Title: Handheld apparatus and photographing device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/CN2019/089706, filed May 31, 2019, which claims priority to International Application No. PCT/CN2018/102454, filed Aug. 27, 2018, the entire contents of both of which are incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the field of image and video photographing devices and, more particularly, to a handheld apparatus and a photographing device, which are applicable to various mobile phones or cameras. 
     BACKGROUND 
     With the appearance of mobile electronic devices including mobile phones and tablets and the improvement of the performance of cameras mounted at these mobile electronic devices, more and more people give up using bulky professional cameras for photographing and instead use the above mobile electronic devices to take photos or videos in daily life or work scenes. 
     In general, when a mobile electronic device such as a mobile phone is used for photographing, the mobile electronic device is usually held by a user, and the length of the user&#39;s arm is limited, resulting in a short distance between a subject to be photographed and a lens of the mobile electronic device. Correspondingly, when one person or multiple people take a selfie, the selfie may become a big-head shot or some people may not be included in the picture. 
     Because of the above problem, a selfie stick that is configured to support a mobile electronic device for photographing is provided in existing technologies. When using the selfie stick, it is only necessary to clamp the mobile electronic device on the selfie stick through clamping arms of the selfie stick, and adjust the length of holding the selfie stick as needed, to achieve photographing requirements at different distances. However, an existing selfie sticks generally only has a fixed length, or only a part of a hollow rod can be extended or retracted to adjust the viewing distance. It is difficult to make full use of the length of the hollow rod to realize the user&#39;s demand for viewing with larger distance. Further, since the clamping arms of the selfie stick completely use the clamping force to clamp the mobile electronic device, the electronic device is easily slipped from the clamping arms, and the safety is poor. 
     SUMMARY 
     In accordance with the disclosure, there is provided a handheld apparatus including a rod and a fixing frame rotatably mounted at a top end of the rod. The fixing frame includes a first buckle member and a second buckle member configured to buckle together to form an opening for accommodating at least a portion of a mobile electronic device. The opening has a close annular shape. At least one of the first buckle member or the second buckle member is provided with a mechanism configured to lock the mobile electronic device. 
     Also in accordance with the disclosure, there is provided a photographing device including a mobile electronic device and a handheld apparatus. The handheld apparatus includes a rod and a fixing frame rotatably mounted at a top end of the rod. The fixing frame includes a first buckle member and a second buckle member configured to buckle together to form an opening for accommodating at least a portion of the mobile electronic device. The opening has a close annular shape. At least one of the first buckle member or the second buckle member is provided with a mechanism configured to lock the mobile electronic device.

       FIG. 1  is a schematic structural diagram of an exemplary photographing device provided by one embodiment of the present disclosure. As shown in  FIG. 1 , the photographing device includes a mobile electronic device and a handheld apparatus  1  for holding the mobile electronic device. 
     In various embodiments, the mobile electronic device may be any suitable electronic device including a mobile phone, a tablet, a camera, or a handheld gimbal. For example, in some embodiments, the mobile electronic device may include a handheld gimbal  9  and a camera may be mounted at the handheld gimbal  9 . 
     As shown in  FIG. 1 , the handheld apparatus  1  includes: a fixing frame  110 , a telescopic rod  200 , a handheld member  400 , and a support structure  600 . The fixing frame  110  is mounted at a top end of the telescopic rod  200 , for supporting the mobile electronic device. As shown in  FIG. 4  and  FIG. 1 , the handheld member  400  is sleeved at a position close to a bottom end of the telescopic rod  200 , such that the bottom end of the telescopic rod  200  may move between a first position and a second position along an axis of the telescopic rod  200  and relative to the handheld member  400 . The support structure  600  is foldably mounted at a bottom end of the handheld member  400 . Further, as shown in  FIG. 5  and  FIG. 7 , when the telescopic rod  200  is in the first position, is able to be in a folded state such that the bottom end of the telescopic rod  200  can be accommodated in the support structure  600 . The support structure  600  can be, e.g., a tripod. 
     In various embodiments, the fixing frame  110  may be a gimbal or another suitable supporting structure including a supporting rod, a supporting block, a supporting platform or a supporting frame. In some embodiments where the fixing frame  110  is not a gimbal, a gimbal may be mounted at the supporting structure that is not a gimbal and the mobile electronic device may be mounted at the gimbal to improve stability of the mobile electronic device. In some other embodiments, the mobile electronic device may be mounted at the supporting structure directly. For example, in various embodiments, the fixing frame  110  may be a single-axis gimbal, a dual-axis gimbal, or a three-axis gimbal suitable for holding the mobile electronic device including a camera or a mobile phone, or a clamping device. 
     In some embodiments, the fixing frame  110  may be mounted at the top end of the telescopic rod  200 . For example, a motor base of the three-axis stabilization gimbal for mounting a yaw axis may be fixed at the top end of the telescopic rod  200 . In some other embodiments, it is also possible to fix a supporting block or a supporting frame at the top end of the telescopic rod  200  as the fixing frame  110 . 
     In some embodiments, as shown in  FIG. 6  and  FIG. 8 , the fixing frame is rotatably connected to the top end of the telescopic rod  200 . The fixing frame  110  may be a supporting platform or another similar structure, such as a structure including a first buckle member  1101  and a second buckle member  1102 , as shown in  FIG. 2  and  FIG. 3 . The first buckle member  1101  and the second buckle member  1102  may be detachably buckled together to form an opening  1103  where the mobile electronic device may pass, such that the mobile electronic device may be mounted. The second buckle member  1102  may be rotatably connected to the top end of the telescopic rod  200 . In some other embodiments, the opening  1103  may be formed at the supporting block, the supporting platform, or other structure connected to the top end of the telescopic rod  200 , to achieve mounting of the mobile electronic device. In some embodiments, the fixing frame  110  may be a frame structure rotatably connected to the top end of the telescopic rod  200 . 
     Optionally, an electrical connection mechanism may be formed at an inner wall of the opening  1103  formed in the fixing frame  110  (or in another part of the fixing frame  110 ), and the mobile electronic device may include an electrical connection structure that cooperates with the electrical connection mechanism. The electrical connection mechanism and the electrical connection structure may be mated together to achieve electrical connection (including at least one of a power supply connection or a communication connection) between the handheld apparatus  1  and the mobile electronic device. For example, the electrical connection mechanism formed at the fixing frame  110  may be a connector of any form, e.g., a wired connector for charging the mobile electronic device, such that the connector may be mated with the interface of the mobile electronic device to realize charging between the handheld apparatus and the mobile electronic device. In some other examples, the electrical connection mechanism may also have other structural forms, including the connector described below or the secondary connection contact. 
     In some embodiments, as shown in  FIG. 6  and  FIG. 8 , the fixing frame  110  is rotatably connected to the top end of the telescopic rod  200  through a damping shaft  1105 , such that the fixing frame  110  may be self-locked when the fixing frame  110  rotates to any position relative to the telescopic rod  200 . The stability and safety of the mobile electronic device mounted at the fixing frame  110  may be improved. Further, the fixing frame may be rotated 360 degrees via adjustment of the damping shaft  1105 , and the angle of the fixing frame  110  may be adjusted freely during use to achieve the purpose of adjusting the orientation of the mobile electronic device. In some other embodiments, the fixing frame  110  may be connected to the telescopic rod  200  rotatably by hinge connection or other means. 
     In some embodiments, to realize the rotational connection between the fixing frame  110  and the top end of the telescopic rod  200 , two opposite lugs  1104  may be formed at the fixing frame  110 , and the two lugs  1104  may be provided with bearing holes  11041 . Therefore, the damping shaft  1105  may pass through the top end of the telescopic rod  200  and be supported by the bearing holes  11041  of the two lugs  1104 . 
     Optionally, the above damping shaft  1105  may include a polygonal shaft, and the bearing holes  11041  formed in the lug  1104  may include polygonal holes matching the shape of the polygonal shaft, such as regular hexagon holes. Correspondingly, shape matching between the shaft and bearing holes  11041  may realize the restriction on the rotation angle of the fixing frame  110 . 
     As shown in  FIG. 4  and  FIG. 5 , the telescopic rod  200  includes a plurality of rods with small to large inner diameters sleeved one over another. The rod with the smallest inner diameter is used to hold the fixing frame  110 , and the handheld member  400  is sleeved over the rod with the largest inner diameter at a position close to an end of the rod. As such, the telescopic function of the telescopic rod  200  can be realized, and the bottom end of the telescopic rod  200  may move between the first position and the second position relative to the handheld member  400  along the axis of the telescopic rod  200 . In another embodiment, some parts of the rod are made to have a continuously folding structure to realize the telescopic rod. 
     To realize the communication connection between the mobile electronic device and the handheld member  400 , as shown in  FIG. 12  and  FIG. 13 , in some embodiments, a communication wire  300  is inserted into the telescopic rod  200 . A first end of the communication wire  300  extends out of the telescopic rod  200  and into the handheld member  400  to be electrically connected to the controller  500  disposed at the handheld member  400 . As shown in  FIG. 8 , a second end of the communication wire  300  extends out of the telescopic rod  200  and into the above fixing frame  110  to be connected to the mobile electronic device mounted at the fixing frame  110 . In order to adapt to the movement of the bottom end of the telescopic rod  200  between the first position and the second position relative to the handheld member  400 , a length of the communication wire  300  extending into the handheld member  400  is reserved with sufficient length variation margin such that the communication wire  300  may extend or bend to adapt to the above position changes. In some other embodiments, to avoid wiring problem, the communication wire  300  may be omitted, and the communication between the handheld member  400  and the mobile electronic device may be established via a wireless connection (including but not limited to WIFI, ZigBee, Bluetooth, infrared, etc.). In some other embodiments, the communication wire  300  may be disposed outside the telescopic pole  200 . 
     Since the telescopic rod  200  needs to be extended or shortened during use, the communication wire  300  disposed in the telescopic rod  200  may have a reserved length so that it may stretch or bend as the telescopic rod  200  is extended or shortened. For example, a part of the communication wire  300  located in the telescopic rod  200  may have a spiral shape. The possibility of the communication wire  300  being broken due to repeated folding of the same part may be reduced. 
     In some embodiments of the present disclosure, as shown in  FIG. 9 , the first end of the communication wire  300  extends out of the telescopic rod  200  and into the handheld member  400  to be electrically connected to the controller  500  disposed at the handheld member  400 . As shown in  FIG. 8 , the second end of the communication wire  300  extends out of the telescopic rod  200  and into the above fixing frame  110  to be connected to the mobile electronic device mounted at the fixing frame  110 . Two ends of the communication wire  300  penetrate openings at two ends of the telescopic rod  200  respectively, such that other modification on the telescopic rod  200  may be avoided. Process of production and cost may be reduced, and the strength of the telescopic rod  200  may not be affected. 
     In some embodiments, a bottom cover  2102  is sleeved at the bottom end of the telescopic rod  200 . After passing through the opening at the bottom end of the telescopic rod  200 , the first end of the communication wire  300  may first pass through a gap between the bottom cover  2102  and the telescopic rod  200 , and then extend into the handheld member  400 . With the bottom cover  2102  provided, when the bottom end of the telescopic rod  200  is in the first position, the top end of the bottom cover  2102  may be covered by the handheld member  400  to prevent the communication wire  300  from being exposed to the external air environment to maintain the overall aesthetics and reduce the possibility of damage to the communication wire  300 . 
     In some other embodiments, the first end of the communication wire  300  may not pass through the opening at the bottom end of the telescopic rod  200 . Instead, near the bottom end of the telescopic rod  200  (for example, at a first predetermined distance from an edge of the bottom end), a first wire-passing hole may be formed, such that the first end of the communication wire  300  may pass through the first wire-passing hole and then extend into the handheld member  400 . To prevent the first cable hole from being seen by the user and improve the overall aesthetics, the first wire-passing hole may be configured to be blocked by the handheld member  400  when the bottom end of the telescopic rod  200  is in the second position and to be blocked by the folded support structure  600  when the bottom end of the telescopic rod  200  is in the first position. 
     Similar to the first end of the communication wire  300 , in some embodiments, the second end of the communication wire  300  may not pass through the top end of the telescopic rod  200 , but instead a second wire-passing hole may be formed near the top end of the telescopic rod  200  (that is, at a position at a predetermined distance from an edge of the top end), such that the second end of the communication wire  300  may pass through the second wire-passing hole and extend into the fixing frame  110 . Correspondingly, the communication wire  300  may be connected to the mobile electronic device disposed at the fixing frame  100  conveniently. 
     To realize the electrical connection between the second end of the communication wire  300  extending into the fixing frame  110  and the movable electronic device, the above electrical connection mechanism may be provided at the fixing frame  110  such that the electrical connection mechanism may be electrically connected to the movable electronic device and electrically connected to the second end of the communication wire  300 . For example, when the movable electronic device is a mobile phone, a Micro-b connector electrically connected to the second end of the communication wire  300  may be mounted at the fixing frame  110 . In use, the interface of the mobile phone is matched with the Micro-b connector of the fixing frame  110  to realize the communication connection and power supply connection between the mobile phone and the controller  500  located at the handheld member  400  described below. In various embodiments, the electrical connection mechanism may be any suitable plug type such as a USB connector, a Type-c connector, a Micro-b connector or a pin plug connector. In some embodiments, the electrical connection mechanism may also be a secondary connection contact that matches a primary connection contact of a mobile electronic device (such as a handheld gimbal). Optionally, the electrical connection mechanism may be formed at the inner wall of the opening  1103  of the fixing frame  110  for the movable electronic device to pass through, or may be formed at the top surface of the supporting platform-type fixing frame  110 . 
     As shown in  FIG. 9  and  FIG. 10 , in some embodiments, the handheld member  400  adopts a sleeve with openings at both ends to realize the function of the telescopic rod  200  being able to move relative to the handheld member  400 . As shown in  FIG. 2  to  FIG. 5 , the handheld member  400  is provided with a controller  500 . The controller  500  may be provided with a joystick for controlling movement of a gimbal, or one or more control buttons (including but not limited to a camera button, a video button, a mode button, etc.) to control the mobile electronic device fixed at the fixing frame  110 . In some embodiments, the controller  500  may also be provided with a functional interface, such as a charging port or a USB interface. The controller  500  may be in communication connection with the mobile electronic device mounted at the fixing frame  110 , for example, through a wireless connection, the communication wire  300  running through the telescopic rod  200 , or the communication wire  300  outside the telescopic pole  200 , as mentioned above. 
     In some embodiments, to realize that the bottom end of the telescopic rod  200  may move between the first position and the second position relative to the handheld member  400 , various structures including a thread structure or a spring structure may be adopted. Specifically, in some examples, internal threads may be formed at the inner wall of the handheld member  400  and external threads may be formed at the outer wall of the telescopic rod  200 . Correspondingly, when the telescopic rod  200  is screwed, the bottom end of the telescopic rod  200  may move relative to the handheld member  400 . In some other embodiments, an upper rib (or lower rib) may be formed at the inner wall of the handheld member  400 , and a lower rib (or upper rib) may be formed at the outer wall of the telescopic rod  200 . A spring may be disposed between the lower rib and the upper rid. Correspondingly, only an external force in the axial direction may need to be applied to the telescopic rod  200  to cause the spring to be compressed or stretched, thereby causing the telescopic rod  200  to move relative to the handheld member  400 . 
     In some embodiments, to limit the position of the bottom end of the telescopic rod  200  when it moves relative to the handheld member  400 , the telescopic rod  200  and the handheld member  400  may be provided with a first limit structure and parts of the first limit structure at the telescopic rod  200  and the handheld member  400  can cooperate with each other. With the first limit structure, the bottom end of the telescopic rod  200  may only move between the first position and the second position relative to the handheld member  400 . As such, on the basis of the telescopic capability of the top of the telescopic end relative to the handheld member  400 , a desired length variation range of the fixing frame  110  relative to the handheld member  400  may be achieved via specific design of the first limit structure to adjust the movement range of the bottom end of the telescopic rod  200 . In some embodiments, the first position and the second position may be the upper and lower limit positions that allow the bottom end of the telescopic rod  200  to move respectively. For example, the first position may be the lower limit position of the bottom end of the telescopic rod  200 , and the second position may be the upper limit position of the bottom end of the telescopic rod  200 . 
     In one embodiment, the first limit structure may be a spring pin and a positioning hole that cooperate with each other. The spring pin may be installed at the telescopic rod  200 , and the positioning hole may be opened on the inner wall of the handheld member  400 . In some other embodiments, the first limit structure may be the length of the internal thread or the external thread in the threaded structure for realizing the relative movement of the telescopic rod  200  and the handheld member  400 . In some other embodiments, the first limit structure may be an upper rib and a lower rib in a spring structure for realizing the relative movement of the telescopic rod  200  and the handheld member  400 . 
     In some other embodiments as shown in  FIG. 9 ,  FIG. 10 ,  FIG. 12 , and  FIG. 13 , the first limit structure includes a groove  2101  and a protrusion block  4101  that cooperate with each other, to limit the position of the movement of the telescopic rod  200  relative to the handheld member  400 . For example, in some examples, a groove may be provided at the handheld member  400 , and a protrusion extending into the groove may be formed at the outer wall of the telescopic rod  200 . 
     In some other embodiments, as shown in  FIG. 10  and  FIG. 13 , an axial groove  2101  is provided at the telescopic rod  200 , and a protrusion block  4101  extending into the axial groove  2101  may be formed at the inner wall of the handheld member  400 . In some embodiments, one or more grooves  2101  may be provided at the telescopic rod  200  along the circumferential direction, and the grooves  2101  may be blind grooves or through grooves. Accordingly, one or more protrusion blocks  4101  extending into the axial grooves  2101  may be formed at the inner wall of the handheld member  400 . The height of the protrusion blocks  4101  may be smaller than the height of the grooves  2101 , such that the grooves  2101  may move up and down relative to the protrusion blocks  4101  to realize the movement of the bottom end of the telescopic rod  200  between the first position and the second position. 
     In some embodiments, the grooves  2101  may be annular. When the annular grooves  2101  are provided at the telescopic rod  200 , the grooves  2101  are blind grooves. Correspondingly, when the grooves  2101  are annular, the protrusion blocks  4101  may also be annular to match the annular grooves  2101 . 
     When the position of the bottom end of the telescopic rod  200  needs to be adjusted, for example, when the bottom end of the telescopic rod  200  needs to be moved from the first position to the second position, it may be only necessary to pull the telescopic rod  200  from the top end of the telescopic rod  200  or push the telescopic rod  200  from the bottom end of the telescopic rod  200  to move the protrusion blocks  4101  of the first limit structure to the top surface  21011  of the grooves  2101  of the first limit structure. When the bottom end of the telescopic rod  200  needs to be moved from the second position to the first position, it may be only necessary to push the top end of the telescopic rod  200  or pull the bottom end of the telescopic rod  200 , such that the protrusion blocks  4101  of the first limit structure move toward the bottom surface  21012  of the grooves  2101  of the first limit structure. 
     Further, in some embodiments, the handheld member  400  and the telescopic rod  200  may be also provided with a lock structure including parts that cooperate with each other for locking the handheld member  400  and the telescopic rod  200  when the bottom end of the telescopic rod  200  moves to a predetermined position. For example, in some embodiments, a matching structure including a fixing pin and a fixing hole may be used as the locking structure to realize the locking function of the handheld member  400  and the telescopic rod  200 . For example, a first positioning hole may be opened on the handheld member  400 , and a plurality of second positioning holes may be opened on the telescopic rod  200 . The first positioning hole at the handheld member  400  and the second positioning hole at the telescopic rod  200  may be aligned. When the bottom end of the telescopic rod  200  moves to the user&#39;s expected position (i.e., the predetermined position), the fixing pin may be passed through the first positioning hole and a second positioning hole aligned with it to lock the handheld member  400  and the telescopic rod  200 . 
     As shown in  FIG. 9 ,  FIG. 10 ,  FIG. 12  and  FIG. 13 , in some embodiments, a friction structure is be used to lock the handheld member  400  and the telescopic rod  200 . Through the design of the frictional force of the friction structure, it may be realized that the telescopic rod  200  and the handheld member  400  may be self-locked at any position between the first position and the second position without external force, to improve stability and security performance of the handheld apparatus  1 . For example, as shown in  FIG. 10  and  FIG. 13 , the friction structure includes a friction plate  4102  provided at the inner wall of the handheld member  400 , and the friction plate  4102  cooperates with a friction surface  2103  at the telescopic rod  200  to improve friction between the handheld member  400  and the telescopic rod  200 , such that the self-locking function is achieved. In some other embodiments, the friction plate  4102  may also be arranged at the outer wall of the telescopic rod  200 , and the inner wall of the handheld member  400  may be provided with a friction surface  2103  matching the friction plate  4102 . 
     Optionally, the friction plate  4102  may be arranged at a position close to the first limit structure to avoid mutual influence between the friction plate  4102  and the first limit structure. Further, the friction plate  4102  may also be arranged separately, to facilitate the replacement of the friction plate  4102 . For example, as shown in  FIG. 10  and  FIG. 13 , the friction plate  4102  may include a first friction plate  4102  and a second friction plate  4102  respectively disposed at two ends of the first limit structure along the axial direction of the telescopic rod  200 . By setting up the friction plates  4102  at two ends of the first limit structure, the area of the friction surface  2103  may be increased, and a better friction value may also be obtained to ensure a good locking effect. In addition, in some embodiments, the friction plate  4102  may be an annular friction plate  4102  to increase the circumferential friction force of the entire telescopic rod  200 , thereby further improving the locking effect. 
     As shown in  FIG. 2 , in some embodiments, the support structure  600  is fixed at the bottom end of the handheld member  400 . The support structure may transform freely between the folded state shown in  FIG. 2  to  FIG. 5 ,  FIG. 7  and  FIG. 9  and the extended state shown in  FIG. 11  and  FIG. 13 . In the following, the matching relationship between the changes in the status of the support structure  600  and the position changes of the telescopic rod  200  is briefly described in connection with the drawings, to more clearly illustrate the matching relationship between the telescopic rod  200 , the handheld member  400 , and the support structure  600 . 
     As shown in  FIG. 4 ,  FIG. 5 ,  FIG. 7  and  FIG. 9 , when the telescopic rod  200  is in the first position, the support structure  600  is in a folded state to accommodate the bottom end of the telescopic rod  200  in the support structure  600 . In another embodiment, when the telescopic rod  200  is in the first position, the support structure  600  may be in the extended state as shown in  FIG. 11  and  FIG. 13 . When the telescopic rod  200  is in the second position, the support structure  600  may also be in the open state or the folded state. In general, when the support structure  600  is in the extended state, the bottom end of the telescopic rod  200  is usually moved to the second position. 
     When the telescopic rod  200  is in the first position, if the support structure  600  is in the folded state, the top end of the telescopic rod  200  may be directly pulled to move the bottom end of the telescopic rod  200  from the first position to the second position, and then whether to extend the support structure  600  may be determined according to the situation. In some other embodiments, the support structure  600  may be extended first, and then the bottom end of the telescopic rod  200  may be pushed or the top end of the telescopic rod  200  may be pulled to move the bottom end of the telescopic rod  200  from the first position to the second position. Subsequently, whether to fold the support structure  600  may be determined according to the situation. When the support structure  600  is in the extended state, either the top end of the telescopic rod  200  may be directly pulled or the bottom end of the telescopic rod  200  may be pushed directly, to move the bottom end of the telescopic rod  200  from the first position to the second position, and then whether to fold the support structure  600  may be determined according to the actual condition. 
     When the telescopic rod  200  is in the second position and the support structure  600  is in the folded state, the top end of the telescopic rod  200  may be directly pushed to move the bottom end of the telescopic rod  200  from the second position to the first position, and then whether to extend the support structure  600  may be determined according to the situation. In some other embodiments, the support structure  600  may be extended first, and then the bottom end of the telescopic rod  200  may be pulled or the top end of the telescopic rod  200  may be pushed to move the bottom end of the telescopic rod  200  from the second position to the first position. Subsequently, whether to fold the support structure  600  may be determined according to the situation. If the support structure  600  is in the extended state, either the top end of the telescopic rod  200  may be directly pushed or the bottom end of the telescopic rod  200  may be pulled directly, to move the bottom end of the telescopic rod  200  from the second position to the first position. Then whether to fold the support structure  600  may be determined according to the actual condition. 
     In various embodiments, when the telescopic rod  200  is in the second position, the bottom end of the telescopic rod  200  may be accommodated in the handheld member  400 , or may be located outside the handheld member  400 , which may be set by those skilled in the art according to actual needs. 
     As shown in  FIG. 11  and  FIG. 12 , the support structure  600  generally includes a plurality of legs  6101 . In some embodiments, the support structure  600  includes three legs  6101 , and is called a tripod  600 . In some embodiments, each leg  6101  is rotatably connected with the handheld member  400 . Specifically, as shown in  FIG. 13 , each leg  6101  and the handheld member  400  are hinged together by a hinge shaft, such that each leg  6101  may rotate relative to the handheld member  400  around the hinge shaft to achieve free transformation between the extended state and folded state. 
     As shown in  FIG. 13 , to limit the opening angle of the leg  6101 , a limit surface  4103  that cooperates with the plurality of legs  6101  is formed at the bottom end of the handheld member  400 , such that the limit surface  4103  may block the plurality of legs  6101  when the legs  6101  are opened by a preset angle to restrict the plurality of legs  6101  from further rotating. Correspondingly, the opening range of the support structure  600  is controlled by limiting the angle of rotation of the legs  6101 . For example, the limit surface  4103  may be configured such that when the plurality of legs  6101  rotate to this position and abut against the limit surface  4103 , the structure formed by the plurality of legs  6101  may enable the telescopic rod  200  located at the center, the fixing frame  110  mounted at the top of the telescopic rod  200 , and the mobile electronic equipment at the fixing frame  110  to stably stand on the ground or table to ensure safety. 
     As shown in  FIG. 9  and  FIG. 12 , each leg  6101  is formed with a recessed part  61011 . The recessed parts  61011  of the plurality of legs  6101  in the folded state enclose to form an accommodation cavity. When the bottom end of the telescopic rod  200  is located at the first position, the whole bottom end of the telescopic rod  200  may be accommodated in the accommodating cavity. 
     In the handheld apparatus  1  provided by various embodiments of the present disclosure, the bottom end of the telescopic rod  200  may move between the first position and the second position relative to the handheld member  400  sleeved near the bottom end of the telescopic rod  200  along the axis of the telescopic rod  200 . Correspondingly, the flexibility of adjusting the length of the handheld apparatus  1  may be improved to meet the user&#39;s viewing requirements in a large range. Moreover, when the bottom end of the telescopic rod  200  is in the first position, the support structure  600  may wrap the bottom end of the telescopic rod  200  in the folded state, such that the support structure  600  may be used as a part of the user&#39;s grip. The length of the handheld member  400  may be reduced, thereby reducing the weight of the handheld member  400  in the handheld apparatus  1  and improving the convenience of use. When the telescopic rod  200  is in the second position, the support structure  600  not only can be configured in the folded state to facilitate the user to hold for handheld remote viewing, but also can be configured in the extended state to be mounted on a support such as the ground or a desktop for photographing. 
     Further, the handheld apparatus  1  provided by the present disclosure may make the distance between the fixing frame  110  and the handheld member  400  farther without increasing the length of the telescopic rod  200 , such that more scene content may be captured when the user takes a selfie. For example, the user may capture a full-body portrait of the user, or capture more people in a group photo or more background content in the screen. When the user is photographing other objects, the camera may be made closer to the subject, to obtain clearer images. For example, it may be suitable for close photographing of distant objects such as plants outside the cliff or lotus at the lake or objects that are not suitable for close proximity. 
     In some embodiments, the long distance viewing may include not only the case where the user moves the camera away from the user when taking a selfie, but also the case where the user moves the camera closer to an object when photographing the object. When the user takes a selfie, since the camera needs to be kept farther away from the user, the distance between the handheld member  400  of the handheld apparatus  1  and the fixing frame  110  should be farther to meet the viewing requirements. When the user photographs other objects, the camera needs to be closer to the objects, and farther away from the user. Therefore, the distance between the handheld member  400  of the handheld apparatus  1  and the fixing frame  110  should also be larger to meet the viewing requirement. 
     The present disclosure provides a photographing device based on the previous embodiments. An electrical connection between a mobile electronic device of the photographing device and the fixing frame of the handheld apparatus may be achieved through contact points. The electrical connection mechanism between the mobile electronic device and the handheld apparatus can be simplified. The volume and weight of the photographing device can be reduced, and quick disassembly and assembly can be achieved. 
       FIG. 14  is a schematic partial structural diagram of the fixing frame of the handheld apparatus shown in  FIG. 1 .  FIG. 15  is a front view of the handheld gimbal shown in  FIG. 1 , and  FIG. 16  is a schematic partial structural diagram of the main body shown in  FIG. 15 . 
     In some embodiments, as shown in  FIG. 1  to  FIG. 3 ,  FIG. 8 , and  FIG. 14  to  FIG. 16 , the photographing device includes: the handheld apparatus  1  and a handheld gimbal  9  (or another mobile electronic device) detachably mounted at the fixing frame  110  of the handheld apparatus  1 . In these embodiments, the structure of the handheld apparatus  1  except for the electrical connection mechanism is similar to the example embodiments described above, which can be referred to for details and will not be repeated here. 
     Specifically, as shown in  FIG. 1  and  FIG. 15 , the handheld gimbal  9  includes: a main body  901  with a substantially rounded rectangular shape, and a gimbal camera  902  (such as a single-axis gimbal camera  902 , a double-axis gimbal camera  902 , or a three-axis gimbal camera  902 ) fixed at a top end of the main body  901 . A camera or another electronic equipment with photographing function may be mounted at the gimbal camera  902 . The main body  901  is provided with a display screen  9011 , a mounting slot  9012 , a control knob  9013 , etc. The display screen  9011  may be used to observe the images captured by the camera in real time or display the functions of the handheld gimbal  9 . The mounting slot  9012  is provided with an electrical connection mechanism for mating with an electrical connection mechanism provided at the handheld apparatus  1 , to realize at least one of functions including power supply or signal transmission between the handheld gimbal  9  and the handheld apparatus  1 . The control knob  9013  may be used to control operation of the handheld gimbal  9  or adjust the parameters of the handheld gimbal  9 , etc. In some other embodiments, the main body  901  may also have any other suitable shape. In some embodiments, when the handheld gimbal  9  needs to be inserted into the opening  1103  of the fixing frame  110 , the main body  901  may have a size and shape suitable for the opening  1103 . 
     The mating member of the handheld gimbal  9  and the handheld apparatus  1  including the electrical connection mechanism, will be described in detail below for a clear understanding of the solution of this embodiment. 
     As shown in  FIG. 14 , in some embodiments, the fixing frame  110  includes a first buckle member  1101  and a second buckle member  1102 . The first buckle member  1101  and the second buckle member  1102  are detachably buckled together to form an opening  1103  and the handheld gimbal  9  may pass through the opening  1103 . A convex platform  11021  is formed at the inner wall of the second buckle member  1102 . The convex platform  11021  is provided with a secondary connection contact  11021   a  to be electrically connected to a second end of the communication wire  300  passing through the fixing frame  110 . The secondary connection contact  11021   a  is disposed at the convex platform  11021  and is electrically connected to the second end of the communication wire  300  extending into the fixing frame  110 . In another embodiment, the fixing frame  110  may also be an integral block structure. The block structure may be provided with an opening  1103  and the handheld gimbal  9  can pass through the opening  1103 . The convex platform  11021  may be disposed at the inner wall of the fixing frame  110 , and provided with the secondary connection contact  11021   a  electrically connected to the second end of the communication wire  300 . In some other embodiments, the fixing frame  110  may also be any other suitable structure with the opening  1103  formed thereon. 
     To mate with the above secondary connection contact  11021   a,  as shown in  FIG. 15  and  FIG. 16 , the mounting slot  9012  opened on the main body  901  of the hand-held gimbal camera  9  is provided with a primary connection contact  90122  to be mated with the secondary connection contact  11021   b . Correspondingly, when the portable electronic device including the handheld gimbal  9  passes through the opening  1103  on the fixing frame  110  of the handheld apparatus  1  and is detachably connected to the fixing frame  110 , the convex platform  11021  in the fixed opening  1103  is partially accommodated in the mounting slot  9012  of the handheld gimbal  9 , such that the primary connection contact  90122  and the secondary connection contact  11021   b  are in contact to achieve electrical connection. Correspondingly, electrical connection between the handheld gimbal  9  and the controller  500  of the handheld apparatus  1  is achieved. 
     In some embodiments, as showing in  FIG. 14 , the secondary connection contact  1102   b  may include a plurality of secondary connection contacts  11021   b  forming a circular or rectangular secondary connection contact array, to improve reliability of electrical connection between the primary connection contact  90122  and the secondary connection contacts  11021   b . For example, in some embodiments in  FIG. 14 , four secondary connection contacts  11021   b  are arranged in a 2×2 rectangular array. Correspondingly, as shown in  FIG. 16 , the number of the primary connection contacts  90122  mated with the secondary connection contacts  11021   b  in the mounting slot  9012  is the same as the number of the secondary connection contacts  11021   b . The primary connection contacts  90122  form a primary connection contact array, and the shape of the primary connection contact array is the same as that of the secondary connection contact array. Optionally, the plurality of secondary connection contacts  11021   b  may include at least one power supply contact and at least one communication contact, such that the communication connection between the handheld gimbal  9  and the controller  500  of the handheld apparatus  1 , and/or power supply to the handheld apparatus  1  from the handheld gimbal  9 , and/or power supply and control of the handheld apparatus  1  from the handheld gimbal  9  may be achieved through mating the primary connection contacts  90122  with the secondary connection contacts  11021   b . The power supply contact includes a positive contact and a negative contact, to form a power supply loop. 
     As shown in  FIG. 14 , in some embodiments, the convex platform  11021  of the fixing frame  110  is further provided with secondary detection contacts  11021   a.  Correspondingly, as shown in  FIG. 16 , the mounting slot  9012  of the handheld gimbal  9  is also provided with primary detection contacts  90121  which may be mated with the secondary detection contact  11021   a  to detect the assembly state of the handheld gimbal  9  and the handheld apparatus  1 . In some embodiments, the convex platform  11021  may include a plurality of secondary detection contacts  11021   a,  and the plurality of secondary detection contacts  11021   a  may form a circular or rectangular secondary detection contact array. Correspondingly, the primary detection contacts  90121  at the mounting slot  9012  for mating with the secondary detection contacts  11021   a  also may include a plurality of primary detection contacts  90121 , and these primary detection contacts  90122  may be also arranged in a circular or rectangular shape substantially consistent with the shape of the secondary detection contact array. In some embodiments, a secondary detection area may be used instead of the above secondary detection contacts  11021   a.    
     In some embodiments, when the handheld gimbal  9  needs to be mounted at the handheld apparatus  1 , the handheld gimbal  9  may be inserted through the opening  1103  of the handheld apparatus  1 , such that the convex platform  11021  in the opening  1103  may extend into the handheld apparatus  1 . When the primary detection contacts  90121  detect the secondary detection area or the secondary detection contacts  11021   a,  it may be determined that the handheld gimbal  9  has been correctly mounted to the handheld apparatus  1 . Correspondingly, one of the handheld gimbal  9  and the handheld apparatus  1  may supply power to another, or control another to execute one or more instructions, through the electrical connection between the primary connection contacts  90122  and the secondary connection contacts  11021   b . For example, the handheld gimbal  9  may supply power to the controller  500  of the handheld apparatus  1  to avoid the increase in weight caused by the need to mount a battery at the handheld apparatus  1 . Further, multiple instructions may be sent to the handheld gimbal  9  to perform corresponding actions, for example, to control the camera mounted at the handheld gimbal  9  to take pictures and video. In some embodiments, the plurality of primary detection contacts  90121  is provided. Correspondingly, when a preset number of the primary detection contacts  90121  or a portion of the plurality of primary detection contacts  90121  in a preset position detects the secondary detection area or the secondary detection contacts  11021   a  corresponding to these primary detection contacts  90121 , it is determined that the handheld gimbal  9  and the handheld apparatus  1  have been correctly assembled together. As such, the accuracy of detection can be improved. 
     The specific forms of the primary connection contacts  90122 , the secondary connection contacts  11021   b,  the primary detection contacts  90121 , the secondary detection contacts  11021   a , and the secondary detection area are not limited in the present disclosure, and may be any proper form, such as elastic metal contacts or springs. 
     Further, as shown in  FIG. 14 , a positioning groove  11021   c  is formed in the convex platform  11021 . Correspondingly, as shown in  FIG. 16 , a retractable positioning block  136  is provided in the mounting groove  9012  of the handheld gimbal  9  to cooperate with the positioning groove  11021   c  of the convex platform  11021 . Therefore, when the handheld gimbal  9  is mounted in the opening  1103  of the fixing frame  110 , the retractable positioning block  136  may be inserted into the positioning groove  11021   c  of the convex platform  11021 , to limit the position of the handheld gimbal  9  and prevent relative movement of the handheld gimbal  9  and the handheld apparatus  1  in the lateral direction.

     In some embodiments, the connection device  121  may be detachably mounted in the mounting groove  123  opened in the main body  122  of the fixing frame  120 , and may be electrically connected with the main body  122  through contacts. Therefore, no connection wire may be required. Further, the connection devices  121  with different connectors  1212  may be changed conveniently by removing the connectors  121 , to achieve the communication connection with mobile electronic devices with different interfaces. 
     Specifically, in some embodiments, the housing  1211  of the connection device  121  may have a shape similar to a rectangular parallelepiped or a cylinder. When the housing  1211  has the shape of a polyhedron, a smooth transition may be made between two adjacent surfaces. For example, as shown in  FIG. 19  to  FIG. 21 , the housing  1211  of this embodiment includes: a front wall  12111  (the lower left side in  FIG. 19 ), a rear wall  12112  (the upper right side in  FIG. 19 ), and four side walls  12113   a,    12113   b,    12113   c,  and  12113   d  between the front wall  12111  and the rear wall  12112 . A smooth transition is formed between the front wall  12111  and the side wall  12113 , between the four side walls  12113   a,    12113   b,    12113   c,  and  12113   d,  and between the rear wall  12112  and the side walls  12113 , as shown in  FIG. 19  and  FIG. 20 . 
     As shown in  FIG. 19  and  FIG. 20 , in some embodiments, an opening is also be opened at the front wall  12111 , such that the connector  1212  may be inserted into the housing  1211  from the opening. Therefore, the connector  1212  may be connected to the electrical connection piece (for example, a circuit board, etc.) at the housing  1211  to be indirectly connected with the following secondary connection contacts  1213 . In some embodiments, the connector  1212  may also be electrically connected to the following secondary connection contacts  1213  directly or through a connection wire after being inserted into the housing  1211 . In some embodiments, the size of the opening opened in the front wall  12111  may be designed according to actual needs. In addition, the electrical connection piece mounted in the housing  1211  may be any one of a PCB board, an FPC board, or a PCB board and an FPC board that are welded together.

     In some embodiments, the side wall  12113  may include an upper cover and a lower cover that may cooperate together to form an accommodation space that may accommodate the above circuit board, connection wires and other components. In some other embodiments, the side wall  12113  may also be selectively designed as a structure including an upper cover and a lower plate, such that the accommodating space for accommodating other components may also be formed when the upper cover and the lower plate are combined together. For the convenience of assembly, other parts of the housing  1211  except the side wall  12113  provided with the secondary connection contacts  1213  may be formed into an integrated piece by molding or other integral molding. For example, when the side wall  12113  includes an upper cover and the secondary connection contacts  1213  are disposed at the lower board, the front wall  12111 , the rear wall  12112  and the upper cover may be integrated into one piece. Therefore, during assembly, the circuit board, connection wires, etc. may be mounted at the lower board first; and then the upper cover formed integrally with the front wall  12111  and the rear wall  12112  may be closed to the lower plate to complete the mounting of the connection device  121 . 
     Specifically, as shown in  FIG. 19  to  FIG. 21 , the side wall  12113  includes an upper side wall  12113   a,  a lower side wall  12113   b,  and a left side wall  12113   d  and a right side wall  12113   c  located between the upper side wall  12113   a  and the lower side wall  12113   b.  The above secondary connection contacts  1213  may be provided at any one of the upper side wall  12113   a , the lower side wall  12113   b,  the left side wall  12113   d,  or the right side wall  12113   c.  In some other embodiments, the secondary connection contacts  1213  may also be provided at multiple of the upper side wall  12113   a,  the lower side wall  12113   b,  the left side wall  12113   d,  or the right side wall  12113   c,  to improve the reliability of the electrical connection. In some embodiments, the primary connection contacts  1233  may be disposed at the surface of the mounting groove  123  that contacts the secondary connection contacts  1213 . For example, when the secondary connection contacts  1213  are disposed at the lower side wall  12113   b,  the primary connection contacts  1233  may be disposed at the lower surface  123   b  of the mounting groove  123 . When the secondary connection contacts  1213  are disposed at the left side wall  12113   d  or the right side wall  12113   c,  the primary connection contacts  1233  may be disposed at the left side  123   d  or the right side  123   c  of the mounting groove  123 . 
     In some embodiments, as shown in  FIG. 20 , the secondary connection contacts  1213  includes a plurality of secondary connection contacts  1213  forming a circular or rectangular secondary connection contact array, to improve reliability of electrical connection between the primary connection contacts  1233  and the secondary connection contacts  1213 . For example, in some embodiments shown in  FIG. 20 , four secondary connection contacts  1213  are arranged in a 2×2 rectangular array. Correspondingly, the number of the primary connection contacts  1233  mated with the secondary connection contacts  1213  in the mounting groove  123  is the same as the number of the secondary connection contacts  1213 . The primary connection contacts  1233  form a primary connection contact array, and the shape of the primary connection contact array is the same as that of the secondary connection contact array, as shown in the top view of the main body  122  in  FIG. 18  and  FIG. 22 . In some embodiments, the plurality of secondary connection contacts  1213  may include at least one power supply contact and at least one communication contact, such that the communication connection between the mobile electronic device and the handheld apparatus  1 , and/or power supply to the handheld apparatus  1  from the mobile electronic device, and/or power supply and control of the handheld apparatus  1  from the mobile electronic device may be achieved through mating the primary connection contacts  1233  with the secondary connection contacts  1213 . The power supply contact in some embodiments includes a positive contact and a negative contact, to form a power supply loop. 
     As shown in  FIG. 20 , in some embodiments, a secondary detection area  1214  is also provided at the side wall  12113  of the housing  1211 , to mate with the primary detection contacts  1234  provided in the mounting groove  123  for detecting a mounting state of the connection device  121  when the connection device  121  is mounted into the mounting groove  123 . In some embodiments, similar to the secondary connection contacts  1213 , the secondary detection area  1214  may also be provided at one or more of the upper side wall  12113   a,  the lower side wall  12113   b,  the left side wall  12113   d,  and the right side wall  12113   c.  Similar to the primary connection contacts  1233 , the primary detection contacts  133  mated with the secondary detection area  1214  may be also arranged at the surface of the mounting groove  123  that is directly opposite to the secondary detection area  1214 . In some embodiments, the secondary detection area  1214  may be a rectangle as shown in  FIG. 20  or may be a circle or other shapes. 
     In some other embodiments, the secondary detection contacts may be used to replace the secondary detection area  1214 . In some embodiments, a plurality of secondary detection contacts may be arranged at the side wall  12113 , and the plurality of secondary detection contacts may form a circular or rectangular secondary detection contact array. 
     Correspondingly, the primary detection contacts  1234  arranged in the mounting groove  123  for mating with the secondary detection area or the secondary detection contacts may include a plurality of primary detection contacts. The plurality of primary detection contacts  1234  may be arranged into a circle or a rectangular roughly same as the shape of the secondary detection area  1214  or the secondary detection contact array. 
     In some embodiments, when the connection device  121  needs to be mounted to the main body  122  for mating with the mobile electronic device, the connection device  121  may be inserted into the mounting groove  123 . When the primary detection contacts  1234  detects the secondary detection area  1214  or the secondary detection contacts, it may be determined that the connection device  121  has been correctly connected to the main body  122 . Further, through the electrical connection between the primary connection contacts  1233  and the secondary connection contacts  1213 , the main body  122  may supply power to the mobile electronic device connected to the connector  1212  of the connection device  121 , or control the mobile electronic device to execute one or more instructions, or the mobile electronic device may send one or more executable instructions to the fixing frame  120  to control the operation of the mobile electronic device, or the mobile electronic device may also supply power to the fixing frame  120 . In some embodiments where there are multiple primary detection contacts  1234 , when the preset number of the primary detection contacts  1234  or the primary detection contacts  1234  at a preset position all detect the secondary detection area  1214  or the secondary detection contacts corresponding to these primary detection contacts  1234 , it may be determined that the connection device  121  has been correctly connected to the main body  122  to improve the accuracy of detection. 
     The specific forms of the primary connection contacts  1233 , the secondary connection contacts  1213 , the primary detection contacts  1234 , the secondary detection contacts, and the secondary detection area  1214  are not limited in the present disclosure, and may have any technical forms in existing technologies, such as elastic metal contacts or springs. 
     In some embodiments shown in  FIG. 20 , the secondary connection contact array and the secondary detection area  1214  may all be arranged at the lower side wall  12113   b  of the housing  1211 . Further, the secondary detection area  1214  and the secondary connection contact array may be arranged at intervals along the length of the connection device  121 . That is, the secondary detection area  1214  and the secondary connection contact array may be arranged sequentially along the direction away from the connector  1212 . In other words, the secondary detection area  1214  or the secondary detection contact array may be arranged at a position close to the connector  1212 , and the secondary connection contact  1213  array may be arranged at a position far from the connector  1212 . In some embodiment, similarly, the secondary detection area  1214  may be replaced by secondary detection contacts. In some other embodiments, the secondary detection area  1214  or the secondary detection contact array may be arranged at a position away from the connector  1212 , and the secondary connection contact array may be arranged at a position close to the connector  1212 . The present disclosure does not exclude the arrangement of the secondary connection contact  1213  array and the secondary detection area  1214  at the upper side wall  12113   a,  the left side wall  12113   d,  or the right side wall  12113   c.  In these alternative structures, the secondary detection area  1214  may also be replaced by the secondary detection contact array. 
     As shown in  FIG. 19  to  FIG. 21  and a partial left view of the main body  122  shown in  FIG. 23 , sliding grooves  1235  are formed at the left side  123   d  and right side  123   c  of the mounting groove  123 . A protrusion  1215  is formed at each of the left side wall  12113   d  and the right side wall  12113   c  of the housing  1211 . Each protrusion  1215  is matched with a corresponding sliding groove  1235 . Through the two protrusions  1215  extending along the length direction of the connection device  121  at the left side wall  12113   d  and the right side wall  12113   c,  the two protrusions  1215  may be slid into the sliding grooves  1235  on both sides of the mounting groove  123  when the connection device  121  is mounted. Further, the sliding groove  1235  may have upper and lower limit function, and the connection device  121  may not move in the vertical direction, to prevent the connection device  121  from falling from the mounting groove  123 . In some other embodiments, only one protrusion  1215  may be provided at one of the left side wall  12113   d  or the right side wall  12113   c,  or a protrusion  1215  may also be provided at the upper side wall  12113   a  or the lower side wall  12113   b.  In some embodiments, one protrusion  1215  may also be provided at the upper side wall  12113   a  or the lower side wall  12113   b.  Correspondingly, the sliding grooves  1235  provided in the mounting groove  123  and matched with the protrusion  1215  may also be adjusted to the lower surface  123   b  or the upper surface of the mounting groove  123  accordingly. In some embodiments, the first sliding structure and the second sliding structure that are respectively provided in the mounting groove  123  and at the side wall  12113  of the housing  1211  are not limited to the sliding grooves  1235  and the protrusion  1215 , and may be other sliding structures including but not limited to balls, raceways, or rollers. 
     As shown in  FIG. 20  and  FIG. 22 , a retractable positioning block  136  is disposed at the lower surface  123   b  of the mounting groove  123 , and a positioning groove  1216  is formed at the lower side wall  12113   b  of the housing  1211  for matching the retractable positioning block  136 . Therefore, when the connection device  121  is mounted into the mounting groove  123  of the main body  122 , the retractable positioning block  136  may be inserted into the positioning groove  1216  of the lower side wall  12113   b  of the housing  1211 , to limit the position of the connection device  121  and prevent the connection device  121  from moving in the lateral direction. Further, the connection device  121  may be also prevented from falling from the main body  122 . In some other embodiments, the positioning groove  1216  may also be disposed at the upper side wall  12113   a,  the left side wall  12113   d,  or the right side wall  12113   c.  Correspondingly, the retractable positioning block  1236  matched with the positioning groove  1216  may be also correspondingly disposed at the upper surface, the left side  123   d  or the right side  123   c  of the mounting groove  123 . In some embodiments, the retractable positioning block  1236  may be an elastic positioning pin or other similar structures. 
     In some other embodiments, the above cooperating retractable positioning block  1236  and positioning groove  1216  may also be replaced by other cooperating first positioning structure and second positioning structure of other suitable forms, including but not limited to snap ring and retaining ring, claw, or other structures. For example, an elastic positioning pin may be provided at the housing  1211 , and a through hole matching the elastic positioning pin may be opened on the main body  122 . The through hole may be connected to the mounting groove  123 , and the elastic positioning pin may penetrate into the through hole and extend out of the main body  122 . Therefore, when the connection device  121  is mounted in the mounting groove  123 , the positioning function may be achieved by the cooperation of the elastic positioning pin and the through hole. When the connection device  121  needs to be removed, the elastic positioning pin may be unlocked by disengaging it from the through hole, such that the connection device  121  may be taken out from the mounting groove  123 . 
     In some embodiments, the secondary detection area  1214 , the positioning groove  1216 , and the secondary connection contacts  1213  may be arranged at the lower side wall  12113   b  of the housing  1211  as shown in  FIG. 20 , and arranged in sequence along the length direction of the connection device  121 . For example, the secondary detection area  1214 , the positioning groove  1216 , and the secondary connection contacts  1213  may be arranged in sequence along the direction away from the connector  1212  as shown in  FIG. 20 . Similarly, in some embodiments, the secondary detection area  1214  described above may be replaced by secondary detection contacts. In some other embodiments, the positioning groove  1216 , the secondary connection contacts  1213 , and the secondary detection area  1214  (or the secondary detection contacts) may not be provided at the same side wall of the housing  1211 , or only two of them may be disposed at the same side wall of the housing  1211 . For example, the positioning groove  1216  and the secondary connection contacts  1213  may be provided at the same side wall  12113  of the housing  1211 , and the secondary detection area  1214  or the secondary detection contacts may be provided at a different side wall  12113 . For example, the positioning groove  1216  and the secondary connection contacts  1213  may be provided at the lower side wall  12113   b,  and the secondary detection area  1214  or the secondary detection contacts may be provided at the left side wall  12113   d  or the right side wall  12113   c.    
     In some embodiments, to facilitate the release of the positioning between the positioning groove  1216  and the retractable positioning block  1236 , the positioning groove  1216  may penetrate the entire housing  1211  to form a positioning through hole, and an elastic pressing part may be provided in the positioning through hole. Therefore, when the connection device  121  needs to be detached from the mounting groove  123 , the retractable positioning block  1236  that extends into the positioning through hole may be compressed by pressing the elastic pressing part to release its blocking effect at the connection device  121 . Furthermore, the connection device  121  may be easily taken out of the mounting groove  123 . As shown in  FIG. 20 , the positioning hole penetrates the upper side wall  12113   a  and the lower side wall  12113   b  of the housing  1211 , and the retractable positioning block  1236  is disposed at the lower surface  123   b  of the mounting groove  123 . An elastic pressing part is provided in the positioning hole. The elastic pressing part may protrude outside the housing  1211 , such as protrude from the upper side wall  12113   a  of the housing  1211 . 
     As shown in  FIG. 17 ,  FIG. 18 ,  FIG. 22  and  FIG. 23 , the mounting groove  123  of the main body  122  is opened at the top of the main body  122 , thereby forming a shape including a front opening  123   e  and an upper opening  123   a.  That is, in some embodiments, the mounting groove includes: a front opening  123   e,  a rear surface opposite to the front opening  123   e,  an upper opening  123   a  located between the front opening  123   e  and the rear surface, a lower surface  123   b,  a left side  123   d,  and a right side  123   c.  Correspondingly, when the above elastic pressing part is mounted in the positioning through hole of the connection device  121  and the connection device  121  is mounted at the main body  122 , the elastic pressing part may protrude from the opening surface of the upper opening  123   a  to facilitate the user&#39;s press. In some embodiments, the size of the upper opening  123   a  of the mounting groove  123  may be designed according to actual needs. It may be understood that in the main body with the structure of this embodiment, the primary connection contacts  1233 , the primary detection contacts  1234 , the retractable positioning block  1236  and the sliding groove  1235  provided in the mounting groove  123  may be provided at one or more of the left side  123   d,  the right side  123   c,  and the lower surface  123   b  of the mounting groove  123 . For example, in some embodiments, the primary connection contacts  1233 , the primary detection contacts  1234 , the retractable positioning block  1236  and the sliding groove  1235  may be provided at the lower surface  123   b  as shown in  FIG. 22 . 
       FIG. 24  illustrates a partial cross-sectional view of another main body provided by various embodiments of the present disclosure. As shown in  FIG. 24 , the mounting groove  123  is opened between the top and bottom of the main body  122 . That is, the mounting groove  123  in this example includes a front opening  123   e,  a rear surface opposite to the front opening  123   e , an upper surface  123   f,  a lower surface  123   b,  a left side  123   d,  and a right side  123   c  located between the front opening  123   e  and the rear surface. Further, one or both of the primary connection contacts  1233  and the primary detection contacts  1234  provided in the mounting groove  123  may be both provided at the upper surface  123   f.  In some other embodiments, the primary connection contacts  1233  and the primary detection contacts  1234  may be provided at one or more of the lower surface  123   b,  the left side  123   d,  and the right side  123   c  of the mounting groove. Optionally, for the convenience of unlocking, in some embodiments, the retractable positioning block  1236  may be provided at the lower surface  123   b,  and an escape hole  1221  opposite to the retractable positioning block  1236  may be disposed at the upper surface  123   f,  to make the connection device  121  more flexible. The pressing part may pass through the escape hole  1221  to facilitate pressing operation to unlock the connection between the connection device  121  and the main body  122 . In practical applications, when the mounting groove  123  also has only one opening surface, a position or shape of the opening surface may be adjusted accordingly as needed. For example, in some embodiments, all of or a part of the upper surface  123   f  of the mounting groove  123  in contact with the elastic pressing part may be made of an elastic material such as silica gel to facilitate the pressing of the elastic pressing part through the upper surface  123   f,  which is not specifically limited here. 
     In some embodiments, the connection device  121  may be mounted in the mounting groove  123  in the forward direction and in the reverse direction, to make the storage of the connection device  121  may be more convenient. The connection device  121  may be mounted in the mounting groove  123  in the forward direction as shown in  FIG. 17 , such that the connector  1212  of the connection device  121  may protrude from the mounting groove  123  to facilitate the mating of the mobile electronic devices. Further, the connection device may also be reversely mounted into the mounting groove  123  as shown in  FIG. 18 , such that the connector  1212  of the connection device  121  is also received in the mounting groove  123  to avoid that the connector  1212  of the connection device  121  interferes with other objects. Therefore, the connector  1212  may be protected and the mounting and transportation of the fixing frame  120  may be facilitated. 
     Specifically, to enable the connection device  121  to be mounted in the mounting groove  123  in the forward and reverse directions, as shown in  FIGS. 18 and 22 , the mounting groove  123  may include a first receiving groove for receiving a housing  1231  of the connection device  121  and a second receiving groove  1232  for receiving the connector  1212  of the connection device  121 . The level of the lower surface of the first receiving groove  1231  is lower than the level of the lower surface of the second receiving groove  1232 . It may be understood that when the connection device  121  is mounted in the mounting slot  123  in the forward direction, the secondary detection area  1214  or the secondary detection contacts of the connection device  121  may contact the primary detection contacts  1234  in the mounting groove  123 , the secondary connection contacts  1213  may contact he primary connection contacts  1233 , and the retractable positioning block  1236  in the mounting groove  123  may be clamped into the positioning slot  1216  of the connection device  121 . When the connection device  121  is mounted in the mounting groove  123  in the reverse direction, the primary detection contacts  1234  does not contact the secondary detection area  1214  or the secondary detection contacts, and the primary connection contacts  1233  may not contact the secondary detection contacts  113 , but the retractable positioning block  1236  in the mounting groove  123  may be inserted into the positioning groove  1216  of the connection device  121 . 
     For description purposes only, the embodiment in  FIG. 17  and  FIG. 18  where the mounting groove  123  is disposed in the horizontal direction and the primary connection contacts  1233  are disposed at the lower surface  123   b  of the mounting groove  123  to improve the reliability of the electrical connection, is used as an example to illustrate the present disclosure, and does not limit the scope of the present disclosure. In some other embodiments, the mounting groove  123  may be disposed in the vertical direction or another suitable direction. 
     In some embodiments, the main body  11  of the fixing frame  120  may be mounted at the top end of the telescopic rod  200  by clamping or screwing, or may be rotatably connected to the top end of the telescopic rod  200  provided by the embodiment 1 through a rotation shaft. The mobile electronic device may be electrically connected to the controller  500  at the handheld member  400  through the connection device  121  and the communication wire  300 , such that the controller  500  at the handheld member  4  may control the operation of the mobile electronic device including taking pictures or video. In some embodiments, the mobile electronic device may also be wirelessly connected to the controller  500  at the handheld member  400  via the connection device  121  and the wireless communication circuit electrically connected to the primary connection contacts  1233 , to realize data transfer with the controller  500  of the handheld member  400 . 
     In addition, in some embodiments, the mobile electronic device may supply power to the connection device  121  and the controller  500  at the handheld member  400 . In some other embodiments, the power supply provided at the handheld member  400  may supply power to the mobile electronic device. 
     In the photographing device provided in some embodiments, the fixing frame  120  may be configured to include a main body  122  and a connection device  121  connected with the main body  122  through contacts, such that the connection device  121  with different types of connectors may mate with the mobile electronic devices with the same type of interface. Therefore, the types of mobile electronic device that may be mated with that the handheld apparatus  1  may be expanded. Further, by further improving the mounting groove  123  of the main body  122 , it may be also possible to store the connection device  121  in the main body  122  when the handheld apparatus  1  is not mated with the mobile electronic device, to prevent the connection device  121  from being lost. 
     The present disclosure also provides a handheld apparatus, as shown in  FIG. 25  to  FIG. 34 .  FIG. 25  is a schematic structural diagram of the handheld apparatus where a telescopic rod is in a retraction state and a clamp member is in an accommodation state.  FIG. 26  is a schematic structural diagram of the handheld apparatus in  FIG. 25  where the telescopic rod is in an extension state and the clamp member is in an expanding state. 
     As shown in  FIG. 25  and  FIG. 26 , the handheld apparatus includes: a fixing frame  81 , a telescopic rod  83 , a handheld member  85 , and a clamp member  87 . The fixing frame  81  is mounted at a top end of the telescopic rod  83 , and is used to fix a mobile electronic device such as a handheld gimbal or a camera. In the description below, unless otherwise specified, the handheld gimbal  9  shown in  FIG. 15  will be used as an example of the mobile electronic device, which should not be interpreted as limiting the scope of the present disclosure. The handheld member  85  is disposed at a bottom end of the telescopic rod  83  such that the user may grasp the handheld member  85  to photograph. The handheld member may be used to accommodate the telescopic rod  83 . The clamp member  87  is fixed at the handheld member  85  for clamping any suitable mobile electronic device such as a mobile phone, a tablet computer, a remote control device, or a display device. In some embodiments, mounting the fixing frame  81  at the top end of the telescopic rod  83  includes mounting the fixing frame  81  at the top surface or a side surface of the top end of the telescopic rod  83 . 
     In some embodiments, a telescopic rod  83  with variable length may be used as the rod for mounting the fixing frame  81 . In some other embodiments, a support rod with a fixed length instead of the telescopic rod  83  may also be used to mount the fixing frame  81 . In some embodiments, the handheld apparatus may be provided with the handheld member  85  and a clamp member  87 . In some other embodiments, the clamp member  87  may not be provided as shown in  FIG. 1 , or both the clamp member  87  and the handheld member  85  may not be provided. 
       FIG. 27  and  FIG. 28  illustrate the fixing frame  81 .  FIG. 27  illustrates the structure of the fixing frame  81  in the closed state, and  FIG. 28  illustrates the structure of the fixing frame  81  in the open state. As shown in  FIGS. 27 and 28 , the fixing frame  81  includes a first buckle member and a second buckle member. The first buckle member and the second buckle member are able to be buckled together as shown in  FIG. 27  to form an opening  812 . The opening  812  has a closed ring shape, and the mobile electronic device such as the handheld gimbal  9  or a camera may pass through the opening  812  and be locked in the opening  812 .  FIG. 29  shows that a part of the main body  901  of the handheld gimbal  9  is locked in the annular opening  812  of the fixing frame  81 . Specifically, to lock the handheld gimbal  9  or another mobile electronic device, a locking structure may be provided on at least one of the first buckle member or the second buckle member. Therefore, when the handheld gimbal  9  is mounted at the fixing frame  81 , it may be ensured that the handheld gimbal  9  will not fall from the opening  812  of the fixing frame  81  during operation. In some embodiments, the closed loop formed by the first buckle member and the second buckle member when buckled together may match the shape of a certain part of the mobile electronic device, such that the fixing frame may provide clamping force around the mobile electronic device to further prevent the handheld gimbal from falling from the opening  812 , especially when the center line of the opening  812  is inclined to a horizontal plane to meet the needs of photographing, for example, when the center line of the opening  812  is vertical to the horizontal plane. 
     In some embodiments, as shown in  FIG. 27  and  FIG. 28 , the first buckle member and the second buckle member are rotatably connected to each other, such that buckling or unbuckling of the first buckle member and the second buckle member may be realized by rotating the first buckle member. In some embodiments, the second buckle member may be rotatably connected to the top end of the rod, such that the entire fixing frame  81  may rotate relative to the rod to adjust the angle of the mobile electronic device mounted at the fixing frame  81 . In some other embodiments, the first buckle member and the second buckle member may also be made into separate components, such that the first buckle member may be put at the second buckle member to achieve buckling of the first buckle member and the second buckle member. The fixing frame  81  may also include a connection member and the connection member may be rotatably connected to the top end of the rod. The first buckle member and the second buckle member may be connected to two sides of the connection member respectively and may be mutually buckled. 
     As shown in  FIG. 28 , the first buckle member includes a first half-enclosing frame  811 , and the second buckle member includes a second half-enclosing frame  813 . The first half-enclosing frame  811  and the second half-enclosing frame  813  are complementary to each other, such that the first half-enclosing frame  811  and the second half-enclosing frame  813  may surround the opening  812  for the handheld gimbal  9  to pass through when they are buckled together. The structure for locking the handheld gimbal  9  may be provided at the first half-enclosing frame  811  and/or the second half-enclosing frame  813 . In some other embodiments, other suitable configurations may also be used. For example, a snap fastener may be separately provided and the snap fastener may pass through the first half enclosing frame  811  or the second half enclosing frame  813  to lock the handheld gimbal  9 . 
     In some embodiments, as shown in  FIG. 28 , the first half-enclosing frame  811  includes a first wall  811   a  and a second wall  811   b,  and the second half-enclosing frame  813  includes a third wall  813   a  and a fourth wall  813   b.  The first wall  811   a  and the third wall  813   a  are arranged oppositely, and the second wall  811   b  and the fourth wall  813   b  are arranged oppositely. The bottom end of the third wall  813   a  is provided with two lugs  8132 , and the top end of the telescopic rod  83  is provided with a mating member  831 . The mating member  831  is located between the two lugs  8132 . Coaxial shaft holes are formed in the mating member  831  and lugs  8132 . The rotation shaft passes through the shaft holes at the mating member  831  and the lugs  8132  to rotatably connect the third wall  813   a  and the telescopic rod  83  together. In some embodiments, the rotation shaft may also be configured to be detachable from the lugs  8132  and the mating member  831 , that is, the second half-enclosing frame  813  may be rotatably and detachably mounted at the top end of the telescopic rod  83 . 
     In some embodiments, the photographing angle of the handheld gimbal  9  can be adjusted by rotating the fixing frame  81  relative to the telescopic rod  83 . In some other embodiments, the extension direction of the free end of the main body  901  of the handheld gimbal  9  can be adjusted by rotating the fixing frame  81  relative to the telescopic rod  83 , such that the handheld gimbal  9  can enter different photographing modes and obtain different video effects. For example, when the fixing frame  81  is rotated to the horizontal position of the center line of the opening, the handheld gimbal  9  can enter the flashlight mode; when the fixing frame  81  is rotated to the vertical position of the center line of the opening, the handheld gimbal  9  can enter the vertical photographing mode or inverted photographing mode. The rotation of the fixing frame  81  relative to the telescopic rod  83  can be a rotation of any angle that can be achieved. The photographing mode of the handheld gimbal  9  is not limited to the above description, and can be determined according to the attitude of the main body  901  of the handheld gimbal  9 . 
     In some embodiments, the second half-enclosing frame  813  is rotatably connected to the top end of the telescopic rod  83 , and correspondingly the center line of the opening  812  can be rotated from the horizontal position in  FIG. 27  to the vertical position in  FIG. 28 . Further, since at least one of the first half enclosing frame  811  or the second half enclosing frame  813  is provided with a structure for locking the handheld gimbal  9 , when the opening  812  is rotated to the vertical direction, the handheld gimbal  9  may be not easy to slip out from the opening  812 , and the safety of the handheld gimbal  9  is ensured. 
       FIG. 27  and  FIG. 28  show that the center line of the opening  812  formed by the first half-enclosing frame  811  and the second half-enclosing frame  813  buckled together can be rotated to the horizontal and vertical positions. In some other embodiments, the center line of the opening  812  may also be rotated from any suitable position to another suitable position. To improve the safety of holding the handheld gimbal  9  when the fixing frame  81  rotates, in some embodiments, the shape of the opening  812  formed when the first half-enclosing frame  811  and the second half-enclosing frame  813  are buckled together may match the shape of an outer contour shape of a part of the handheld gimbal  9 . Therefore, when the first half-enclosing frame  811  and the second half-enclosure frame  813  are buckled together, the handheld gimbal  9  can be further clamped to improve the safety of the operation of the handheld gimbal  9  at the handheld apparatus. Moreover, in some embodiments, one or more of the first wall  811   a  and the second wall  811   b  of the first half-enclosing frame  811 , and the third wall  813   a  and the fourth wall  813   b  of the second half-enclosing frame  813  may be further provided with pads  817  (for example, elastic pads), to increase the clamping force of the first half-enclosing frame  811  and the second half-enclosing frame  813  at the handheld gimbal  9 . 
     Further, the rotatable connection between the second half-enclosing frame  813  and the top end of the telescopic rod  83  may be not limited to the above method. In various embodiments, any suitable rotatable connection structure can be used to realize the rotatable connection between the second half-enclosure frame  813  and the top end of the telescopic rod  83 . For example, in some embodiments, the rotatable connection between the second half-enclosing frame  813  and the top end of the telescopic rod  83  can be realized by a hinged connection. 
       FIG. 30  is a top view of the handheld apparatus when the fixing frame  81  is opened. As shown in  FIG. 30 , the first wall  811   a  of the first half enclosing frame and the fourth wall  813   b  of the second half enclosing frame  813  are rotatably connected to each other by a rotation shaft, and the second wall  811   b  of the first half-enclosing frame  811  is provided with a claw  815 , and correspondingly, a buckle is provided at the third wall  813   a  of the second half-enclosing frame  813 . 
     When the fixing frame  81  needs to be closed, the first half-enclosing frame  811  and the second half-enclosing frame  813  can be buckled together by rotating the first half-enclosing frame  811  and engaging the claw  815  at the buckle. When the fixing frame  81  needs to be opened, it is only necessary to disengage the claw  815  from the buckle and rotate the first half-enclosing frame  811  correspondingly to release the first half-enclosing frame  811  and the second half-enclosing frame  813 . 
     The above embodiment where the claw  815  and the buckle are respectively arranged at the first half-enclosing frame  811  and the second half-enclosing frame  813  is used as an example to illustrate the present disclosure, and does not limit the scope of the present disclosure. In some other embodiments, the claw  815  and the buckle may also be arranged at the second half enclosing frame  813  and the first half enclosing frame  811 , respectively. Further, the embodiment where the first half-enclosing frame  811  and the second half-enclosing frame  813  are detachably buckled through the claw  815  and the buckle is used as an example to illustrate the present disclosure, and does not limit the scope of the present disclosure. In some other embodiments, the first half enclosing frame  811  and the second half enclosing frame  813  may also adopt another detachable connection manner such as a bolt connection. 
     As shown in  FIG. 27  to  FIG. 30 , the fourth wall  813   b  of the second half-enclosing frame  813  is also provided with a mounting groove  8139  for mounting other pre-assembled accessories including a fill light. By providing the mounting groove  8139 , additional functions may be provided for the handheld photographing device. For example, when a fill light is mounted in the mounting groove  8139 , it can provide fill light for the camera mounted at the handheld gimbal  9  to improve its photographing quality. 
     As shown in  FIG. 27 , a boss  8131  is provided at the inner surface of the third wall  813   a  of the second semi-enclosing frame  813 , and the boss  8131  includes a surface and a side surface arranged around the surface. A positioning groove  8133  is provided at the surface of the boss  8131 , and correspondingly, a telescopic positioning block is provided at the handheld gimbal  9  shown in  FIG. 15 . When the handheld gimbal  9  needs to be installed at the fixing frame  81 , it is only necessary to pass the handheld gimbal  9  through the opening  812  formed by the first half-enclosing frame  811  and the second half-enclosing frame  813  buckled together, until the retractable positioning block provided at the surface of the gimbal  9  facing the boss  8131  is inserted into the positioning groove  8133  at the boss  8131  to lock the handheld gimbal  9  in the opening  812 . In some other embodiments, a retractable positioning block may also be provided at the boss  8131  and a positioning groove  8133  may be provided at the handheld gimbal  9  accordingly. In addition, the positioning slot  8133  or the retractable positioning block can also be provided at the first half-enclosing frame  811 , or both at the first half-enclosing frame  811  and the second half-enclosing frame  813 , to improve the locking effect. 
     As shown in  FIG. 27 , protrusions  8135  are provided at one or both sides of the boss  8131 , that is, the protrusions  8135  are provided at one side or two opposite sides of the boss  8131 . Accordingly, the handheld gimbal  9  is provided with a sliding groove which is matched with the protrusions  8135 . When mounting the handheld gimbal  9 , the protrusions  8135  at the boss  8131  can slide along the sliding groove of the handheld gimbal  9  to provide guidance and locking for mounting the handheld gimbal  9 .  FIG. 27  shows that the protrusion  8135  is arranged along the direction indicated by the arrow in the figure, such that when the opening  812  of the fixing frame  81  in the figure is rotated from the horizontal direction to the vertical direction of  28  in the figure, the protrusions may provide a certain locking effect to prevent the handheld gimbal  9  from falling from the opening  812 . In some other embodiments, the protrusions  8135  can also be arranged perpendicular to the direction shown by the arrow in the figure. Correspondingly, to prevent the handheld gimbal  9  from sliding down from the opening  812 , the sliding groove provided at the handheld gimbal  9  can be configured with a groove with an opening  812  at only one end (when the center line of the opening  812  is vertical, the closed end of the sliding groove is located below the end of the opening  812 ), such that when the handheld gimbal  9  is mounted in place, the closed end of the sliding groove can contact the protrusions  8135 . Therefore, a supporting force may be provided for the handheld gimbal  9  to further avoid the risk that the handheld gimbal slips off the fixing frame  81  when the opening  812  of the fixing frame  81  rotates to a vertical position. 
     As shown in  FIG. 27 , one or more contacts  8137  are provided at the surface of the boss  8131  and are offset from the positioning groove  8133 . The contacts  8137  can be used for power supply (including but not limited to a power supply from the handheld apparatus for the handheld gimbal  9  or a power supply from the handheld gimbal  9  for the handheld apparatus), communication (including but not limited to transmitting control signals of the handheld device to the handheld gimbal  9 ), or detecting whether the handheld gimbal  9  is mounted in place, etc. When there are multiple contacts  8137 , these contacts  8137  may be evenly or unevenly distributed at the surface of the boss  8131 , and the multiple contacts  8137  may form one group or multiple groups. In some embodiments, these contacts  8137  can form three groups, where the first group is used for power supply, the second group is used for communication, and the third group is used for detecting whether the handheld gimbal  9  is mounted in place. For the arrangement of the contacts  8137  in this embodiment, reference can be made to the embodiments described above, and the detailed description thereof will not be repeated here. Similarly, the descriptions of the positioning groove  8133  at the boss  8131  that cooperates with the retractable positioning block and the protrusions  8135  that cooperates with the sliding groove are also omitted here, for which reference can be made to the embodiments described above. 
     The embodiments where the contacts  8137  and the positioning groove  8133  in  FIG. 27  are both provided at the third wall  813   a  of the second half-enclosing frame  813  are used as examples to illustrate the present disclosure and should not be regarded as a specific limitation of the present disclosure. In some other embodiments, the boss  8131  may not be provided or the boss  8131  may be provided at the fourth wall  813   b  of the second half-enclosing frame  813 . In some other embodiments, one or two of the contacts  8137 , the positioning groove  8133  and the protrusions  8135  may be not arranged at the boss  8131 . For example, the contacts  8137  and the positioning groove  8133  can be arranged at the surface of the boss  8131 , and the protrusions  8135  can be arranged at the fourth wall  813   b  of the second half-enclosing frame  813 , or the protrusions  8135  and the boss  8131  may be staggered at the third wall  813   a.    
     In some embodiments, when the handheld gimbal  9  is mounted at the handheld apparatus, the first half enclosing frame  811  and the second half enclosing frame  813  is unbuckled firstly, and then the first half enclosing frame  811  is rotated to open the fixing frame  81 . The sliding groove of the handheld gimbal  9  is aligned with the protrusions  8135  on both sides of the boss  8131  of the second half-enclosing frame  813 , and the handheld gimbal  9  is pushed until the retractable positioning block at the handheld gimbal  9  is locked into the positioning groove  8133  to hold the handheld gimbal  9  at the second half-enclosing frame  813 . Finally, the first half-enclosing frame  811  is rotated until the claws  815  of the first half-enclosing frame  811  and the second half-enclosing frame  813  are buckled together. When using the handheld apparatus, according to the different photographing angles, the fixing frame  81  can be rotated to drive the handheld gimbal  9  to rotate. For example, the handheld gimbal  9  can be rotated from a horizontal position to a vertical position. When the telescopic rod  83  is used as a rod, the focus distance can also be adjusted by adjusting the length of the telescopic rod  83  to improve the picture quality. 
     For description purposes only, the embodiment where the first buckle member and the second buckle member include complementary semi-enclosing structures is used as an example to illustrate the present disclosure and does not limit the scope of the present disclosure. In some other embodiments, the first buckle member and the second buckle member may also include an all-enclosed structure. For example, in some embodiments, the first buckle member may include a first ring frame, and the second buckle member may include a second ring frame. The first ring frame and the second ring frame may be disposed opposite to each other. When the two ring frames are buckled together, the ring space of the first ring frame and the ring space of the second ring frame together may form an opening for accommodating the camera. In this embodiment, similar to the first buckle member and the second buckle member of the semi-enclosing frame structure, the first ring frame and the second ring frame can also be detachably buckled by setting buckles and claws. A first blocking wall may be formed at the first ring frame (at the opening edge), a second blocking wall may be formed at the second ring frame (or at the opening edge). The first blocking wall, the first ring frame, the second ring frame and the second blocking wall may surround an annular cavity, and the camera may be clamped in the annular cavity. 
     In some embodiments, contacts may also be provided at the first ring frame and/or the second ring frame, to perform power supply and communication with the camera through the contacts or to detect whether the camera is installed in place. It can be understood that, in some embodiments, a boss can also be formed at the first ring frame and/or the second ring frame, such that the contacts are arranged at the surface of the boss. 
     In some embodiments, to lock the camera at the fixing frame  81 , one of the first ring frame and the second ring frame may also be provided with the positioning groove  8133 .

       FIG. 31  illustrates a partial structural diagram showing the position of the fixing frame  81  of the handheld apparatus. As shown in  FIG. 31 , in some embodiments, the handheld apparatus further includes a base  89  with a built-in wireless communication circuit. The wireless communication circuit may be used to communicate with at least one of the external devices or the controller  86  of the handheld apparatus. When the fixing frame  81  is mounted with a handheld gimbal  9 , the base  89  can be mounted at the bottom of the handheld gimbal  9  as shown in  FIG. 31 , such that the image information of the handheld gimbal  9  can be returned to the external device including, for example, the mobile phone  3 , a remote control terminal or servers, and/or control signals from the mobile phone  3 , remote control terminals, and the controller  86  of the handheld apparatus can be transferred to the handheld gimbal  9  to control the working status of the handheld gimbal  9 . For example, in some embodiments, the handheld gimbal  9  can be mounted at the fixing frame  81  and the mobile phone can be clamped at the clamp member  87 , such that the handheld gimbal  9  can perform communication interaction with the mobile phone at the clamp member  87 , including but not limited to returning the image of the camera installed at the handheld gimbal  9  to the mobile phone, or transmitting the control information of the mobile phone to the handheld gimbal  9 , through the base  89  mounting at the handheld gimbal  9 . 
       FIG. 32  and  FIG. 33  are partial structural diagrams of the clamp member  87  of the handheld apparatus after being turned over.  FIG. 32  shows the structure of the clamp member  87  in the unopened state, and  FIG. 33  shows the clamp member  87  in the open state. As shown in  FIG. 32  and  FIG. 33 , the clamp member  87  includes a connection member  871  connected to the handheld member  85  and a clamp body  873  for clamping devices including mobile phones, tablet computers, monitoring devices, or remote control devices. The clamp body  873  is mounted at the connection member  871 .  FIG. 34  illustrates the use of the clamp member  87  to clamp the mobile phone  3  such that the mobile phone  3  and the handheld gimbal  9  mounted at the fixing frame  81  can be used for image transmission. Therefore, the user can monitor the images taken by the camera mounted at the handheld gimbal  9  in real time. In some embodiments, a certain part of the control of the handheld gimbal  9  can also be achieved through the mobile phone  3  clamped at the clamp member  87 . 
     For description purposes only, the embodiments where the clamp member  87  is used to clamp the mobile phone  3  will be described below as examples to illustrate the structure of the clamp member  87  of the present disclosure, which do not limit the scopes of the present disclosure. 
     As shown in  FIG. 32  and  FIG. 33 , the connection member  871  is configured to have a sheet or block shape, and is fixed at the handheld member  85  by screwing, riveting, welding or bonding. In some other embodiments, the connection member  871  may also be configured to be a sleeve shape to be sleeved at the handheld member  85 . 
     The clamp body  873  may be directly fixed at the connection member  871  or rotatably mounted at the connection member  871 . For example, the clamp body  873  may be rotatably connected to the connection member  871  through a shaft or a hinge, such that the clamp body  873  can be turn upside down or left and right relative to the connection portion  871 . As shown in  FIG. 32  and  FIG. 33 , when the clamp body  873  is in the first position, the clamp body  873  is in an expanded state, and the mobile phone  3  can be clamped at the clamp body  873 . As shown in  FIG. 25 , when the clamp body  873  is in the second position (that is, when it is not turn over), the clamp body  873  is in a stored state, which can hug the handheld member  85 , thereby avoiding the collision between the clamp body  873  and external objects. Damage of the clamping portion  87  may be avoided, and the overall appearance of the handheld apparatus may be simpler and more beautiful. In some embodiments, a controller  86  is provided at the handheld member  85  (refer to the above embodiments for the specific structure, which will not be repeated here), the clamp body  873  can cover at least a part of the controller  86 , thereby avoiding touch at the controller  86  by mistake. 
     In some embodiments, the connection member  871  may be detachably connected to the handheld member  85 , and the clamp member  87  may also be detachably mounted at the connection member  871 . These embodiments are used as an example only and do not limit the scopes of the present disclosure. For example, in some other embodiments, the connection member  871  and the handheld member  85  may both be detachable. 
     As shown in  FIG. 32  and  FIG. 33 , the clamp body  873  includes a first clamping arm  8731  and a second clamping arm  8733 . The first clamping arm  8731  and the second clamping arm  8733  jointly enclose a clamping space. One of the first clamping arm  8731  and the second clamping arm  8733  can move relative to another to change the size of the clamping space to selectively mount or remove the camera. In some embodiments, the first clamping arm  8731  can move relative to the fixed second clamping arm  8733 . In some other embodiments, the second clamping arm  8733  can move relative to the fixed first clamping arm  8731 . In some other embodiments, each of the first clamping arm  8731  and the second clamping arm  8733  can move relative to another. 
     Specifically, as shown in  FIG. 32  and  FIG. 33 , the first clamping arm  8731  is rotatably connected to the connection member  871  through a rotation shaft, such that the clamp body  873  can be turned upside down relative to the connection member  871 . The first clamping arm  8731  is also provided with two sliding rods  8731   a,  and the second clamping arm  8733  is sleeved at the two sliding rods  8731   a  and can slide along the sliding rod  8731   a  to move away from or close to the first clamping arm  8731  to change the size of the clamping space. 
     When the mobile phone  3  needs to be clamped to the clamp member  87 , the clamp body  873  may be turned upwards, and then the second clamping arm  8733  may be driven to slide upward along the sliding rod  8731   a  away from the first clamping arm  8731  to open the clamp body  873 . Then the mobile phone  3  may be placed between the opened first clamping arm  8731  and the second clamping arm  8733 , and the second clamping arm  8733  may slide down along the sliding rod  8731   a,  thereby clamping the mobile phone  3  tightly, as shown in  FIG. 25 ,  FIG. 33 , and  FIG. 34 . When the mobile phone  3  needs to be removed from the clamping portion  87 , the second clamping arm  8733  may be driven to slide upward along the sliding rod  8731   a  to open the clamp body  873 . Then the mobile phone  3  may be removed, and the second clamping arm  8733  may be driven to slide down along the sliding rod  8731   a  to close the clamp body  873 . Finally, the clamp body  873  may be turned downward, as shown in  FIG. 32  and  FIG. 25 . 
     Optionally, a tension spring may be provided at the sliding rod  8731   a.  One end of the tension spring may be fixed to the first clamping arm  8731 , and another end of the tension spring may be fixed to the second clamping arm  8733 . Correspondingly, when the second clamping arm  8733  slides along the sliding rod  8731   a  away from the first clamping arm  8731 , once the driving force is removed, the second clamping arm  8733  may move closer to the first clamping arm  8731  under the tension of the tension spring, to clamp the mobile phone  3  or automatically close the clamp body  873 . 
     As shown in  FIG. 32  and  FIG. 33 , a groove  8733   a  is provided at the clamp body  873 , and the groove  8733   a  is used to accommodate an external interface that is detachably connected to the handheld gimbal  9  at the fixing frame  81  (for example, the connection device in the previous embodiments). When the mobile phone  3  is clamped at the clamp body  873 , the groove  8733   a  may be blocked by the mobile phone  3 . 
     In some embodiments, the second clamping arm  8733  may also be connected to the connection member  871 . Accordingly, the first clamping arm  8731  may move downward relative to the second clamping arm  8733 , to move away from the second clamping arm  8733  and open the clamp body  873 . The embodiment where two sliding rods  8731   a  are provided at the first clamping arm  8731  is used as an example to illustrate the present disclosure and does not limit the scope of the present disclosure. In some other embodiments, any suitable number of sliding rods  8731   a  may be provided. 
     In general, in some embodiments, the fixing frame  81  may be provided at the top of the rod. The two buckle members of the fixing frame  81  may form the closed annular opening  812 , such that the handheld gimbal  9  or camera may be inserted into the opening  812  and may be locked at the fixing frame  81  through a structure provided at least one of the buckle members. When the fixing frame  81  is rotatably arranged at the top of the rod, the handheld gimbal  9  or the camera may be locked at the fixing frame  81 , such that the safety of the handheld gimbal  9  or the camera can be ensured. 
     The present disclosure also provides a photographing device including a handheld apparatus and a handheld gimbal consistent with the present disclosure.
