FIG. 8  is an exploded view of the camera support device  100  of  FIG. 7 . The camera support device  100  of the first embodiment of the present disclosure may include a holding structure  2  and a support structure  1 . The holding structure  2  is configured to hold a camera device, such as a mobile phone, a camera, a pad, and etc. The support structure  1  is configured to support the holding structure  2 . 
     In the first embodiment, the support structure  1  includes a telescopic connecting pipe assembly  10 , which includes a first pipe  11 , a second pipe  12  and a first bendable connection assembly  13 . The first bendable connection assembly  13  includes a first pivot part  131  and a second pivot part  132 , the first pivot part  131  includes a first pivot portion  131   a  and a first connection portion  131   b  connecting the first pivot portion  131   a , and the first connection portion  131   b  is accommodated at one end of the first pipe  11  to connect with the first pipe  11 . The second pivot part  132  includes a second pivot portion  132   a  and a second connection portion  132   b  connecting the second pivot portion  132   a . The second connection portion  132   b  connects the second pipe  12 . The second pivoting portion  132   a  is pivoted with the first pivot portion  131   a , so that the support structure  1  can be retracted and bent. The telescopic bendable support structure  1  includes a support state, bent state and retracted state, so that a camera device supported on the camera support device  100  can be in different heights, angles and positions, etc. 
     In the retracted state, the first pipe  11 , the first pivot portion  131   a , the second pivot portion  132   a  can be substantially accommodated in the second pipe  12  so that make a volume of the whole support structure  1  retracted to a volume of the second pipe  12 . In the retracted state, the camera support device  100  can be located on a table for supporting a camera device, especially for broadcast live. 
     In the support state, the first pipe  11  and the second pipe  12  extends in a same direction, at least part of the first pipe  11  extends out of the second pipe  12 . Specifically, in at least one embodiment, in the support state, one part of the first pipe  11  extends out of the second pipe  12 , the other part of the first pipe  11 , the first pivot portion  131   a  and the second pivot portion  132   a  are accommodated in the second pipe  12 . In at least one embodiment, in the support state, the first pipe and the first pivot portion  131   a  can extend out of the second pipe  12 , while the second pivot portion  132   a  can be accommodated in the second pipe  12 . In at least one embodiment, the first pipe  11 , the first pivot portion  131   a  and the second pivot portion  132   a  can extend out of the second pipe  12 . 
     In the first embodiment, the first connection portion  131   b  is accommodated in one end of the first pipe  11  so as to be connected with the first pipe  11 . The second connection portion  132   b  can be accommodated in the second pipe  12  so as to be connected with the second pipe  12 . In the support state, the camera support device  100  can be supported on the ground to support a camera device, which allows a user to freely adjust a height of the support structure  1  according to an object to be photographed. 
     The first connection portion  131   b  can be accommodated in the first pipe  11 . The first connection portion  131   b  and the first pipe  11  can be made separately from the first pipe  11 , which can realize standardized production of the first pipe  11 . In addition, more pipes can be added according to actual requirements. The material for the first pivot part  131 , the second pivot part  132  can be different from that for the first pipe  11  and the second pipe  12 , which can reduce manufacture cost and improve manufacture efficiency so as to improve competitivity of the support structure. The second connection portion  132   b  can be accommodated in the second pipe  12 . The second connection portion  132   b  can be made separately from the second pipe  12 , which can realize standardized production of the second pipe  12 . In addition, more pipes can be added according to actual requirements. The material for the first pivot part  131 , the second pivot part  132  can be different from that for the first pipe  11  and the second pipe  12 , which can reduce manufacture cost and improve manufacture efficiency so as to improve competitivity of the support structure. Furthermore, the first connection portion  131   b  is accommodated in the first pipe  11 , the second connection portion  132   b  is accommodated in the second pipe  12 , which makes the appearance of the support structure more beautiful. 
     The first connection portion  131   b  is accommodated in the first pipe  11 , and the first connection portion  131   b  is arranged separately from the first pipe  11 , which allows a first connecting pipe assembly  14  to pass through the first pipe  11  to be connected with an end of the first pipe away from the second pipe  12 . The second connection portion  132   b  is accommodated in the second pipe  12 , and the second connection portion  132   b  and the second pipe  12  is arranged separately from the second pipe  12 , which allows the second pipe  12  and the second pivot part  132  to pass through a second connecting pipe assembly  15  to be connected with an end of the second pipe  12  away from the first pipe  11 . Therefore, through the first and second connecting pipe assemblies  14  and  15 , the length of the telescopic connecting pipe assembly can be increased, and the position bendable of the telescopic connecting pipe assembly  10  can be adjusted to meet different application scenarios. Specifically, the first pipe  11  and the second pipe  12  can be replaced with standard pipes available in current market, which do not need to design different molds for pipes and reduce manufacture cost. 
     The rigidity of the first pivot part  131  and the second pivot part  132  is greater than that of the first pipe  11  and the second pipe  12 . When the first pivot part  131  and the second pivot part  132  are bent to be connected together, they both bear large external forces. By making the rigidity of the first pivot part  131  and the second pivot part  132  greater than that of the first pipe  11  and the second pipe  12 , deformation problems caused by the large external force of the first pivot part  131  and the second pivot part  132  can be reduced and service life of the support device can be improved. In addition, the first pipe  11 , the second pipe  12 , and the connecting pipe assemblies  14  and  15  can be made of aluminum, which can not only be the standard parts commonly available in the market, but also have low weight while ensuring support and telescopic functions, which is conducive to the lightweight of the support device. 
     In at least one embodiment, the first pivot part  131  and the second pivot part  132  can made of stainless steel. In other embodiments, outer parts of the first pivot part  131  and the second pivot part  132  can be made of stainless steel while inner parts of the first pivot part  131  and the second pivot part  132  can be made of plastic. 
     Except for the first pipe  11  and the second pipe  12 , in order to increase a telescopic range of the support structure and improve application scenes of the camera support device  100 , the pipe assembly  10  of the support structure  1  may further include a number of connecting pipe assemblies  14  and  15  and a connecting assembly  16  connected between two adjacent connecting pipes. Specifically, the first connecting pipe assembly  14  is telescopically connected to the end of the first pipe  11  away from the second pipe  12 , and the second connecting pipe assembly  15  is telescopically connected to the end of the second pipe  12  away from the first pipe  11 . A connecting assembly  16  can be correspondingly arranged between two adjacent pipes (such as between the first pipe  11  and the first connecting pipe assembly  14 , between two adjacent first connecting pipe assemblies  14 , between the second pipe  12  and the second connecting pipe assembly  15 , and between two adjacent second connecting pipe assemblies  15 ), so as to realize a telescopic connection between the two adjacent pipes. 
     In addition, between the two adjacent pipes, an inner diameter of a lower pipe (i.e. the pipe away from the holding structure  2 ) is slightly larger than the outer diameter of the upper pipe (i.e. the pipe adjacent to the holding structure  2 ), so that the upper pipe can be retracted into or extend out of the lower pipe. Specifically, the connecting assembly  16  may include a limit sleeve  168  installed on the lower pipe and at least one position member  167  clamped between the outer wall of the upper pipe and the inner wall of the lower pipe. In this embodiment, at least one position member  167  is arc-shaped. The at least one position member  167  includes a first position member  167   a  and a second position member  167   b  arranged opposite to the first position member  167   a . One of the first position member  167   a  and the second position member  167   b  is a plastic positioning piece, and the other of the first position member  167   a  and the second position member  167   b  is a metal positioning piece. The limit sleeve  168  is configured to prevent the upper pipe from separating from the lower pipe. 
     In the bent state, among the first pipe  11 , the first pivot portion  131   a  and the second pivot portion  132   a , at least the first pipe  11  extends out of the second pipe  12 . The first pivot portion  131   a  and the second pivot portion  132   a  bent relative to each other to be connected together at a preset bending angle, and then the first pipe  11  and the second pipe  12  are connected together through the first bendable connection assembly  13  in a bent state. In other embodiments, in the bent state, all the first pipe  11 , the first pivot portion  131   a  and the second pivot portion  132   a  can extend out of the second pipe  12 . In the bent state, the camera support device  100  can allow the camera device held by the holding structure  2  to take photographs at any required angle by the user by adjusting a bent connection angle (the angle of the first pivot portion  131   a  relative to the second pivot portion  132   a ) which is more convenient for use, thereby improving user experience. 
     In at least one embodiment, in the bent state, the bent connection angle between the first pivot portion  131   a  and the second pivot portion  132   a  (that is the preset bending angle and is equals to an angle between the first pipe  11  and the second pipe  12 ) may be 90 degrees, which allows the camera device held on the holding structure  2  to shoot objects on a horizontal surface like a table surface or the ground, such as papers or documents. However, in other embodiments, the bent connection angle between the first pivot portion  131   a  and the second pivot portion  132   a  is not limited to 90 degrees, and can be 70 degrees, 80 degrees, 110 degrees or 120 degrees according to actual requirements. In addition, in some embodiments, by setting pivoting friction between the first pivot portion  131   a  and the second pivot portion  132   a , the bent connection angle between the first pivot portion  131   a  and the second pivot portion  132   a  can be adjusted in a range of 0-180 degrees to meet the user&#39;s requirements for shooting at different bent angles. 
     Referring to  FIG. 7 , the bent connection between the first pivot portion  131   a  and the second pivot portion  132   a  can be: the first pivot portion  131   a  bends towards a first direction (for example, a right side shown in  FIG. 7 ), so as to form the bent connection with the second pivot portion  132   a  (for example, a bent connection at a 90 degree angle); or the first pivot portion  131   a  bends towards a second direction (for example, a left side shown in  FIG. 7 ), so as to form the bent connection with the second pivot portion  132   a  (for example, a bent connection at a 90 degree angle), thereby meeting different shooting requirements at different positions or angles. 
     The first pivot portion  131   a  may include a pivot hole  131   c , the second pivot portion  132   a  may include a pivot hole  132   c . The first bendable connection assembly  13  further includes a first pivot shaft  134 . The first pivot shaft  134  passes through the pivot hole  131   c  of the first pivot portion  131   a  and the pivot hole  132   c  of the second pivot portion  132   a  to pivotably connect the first pivot portion  131   a  and the second pivot portion  132   a  together. The first pivot shaft  134  includes a first cap  134   a  and a first shaft  134   b  connected with the first cap  134   a . The first shaft  134   b  passes through the pivot hole  131   c  of the first pivot portion  131   a  and the pivot hole  132   c  of the second pivot portion  132   a . The first bendable connection assembly  13  further includes a first fastener  134   c . The first fastener  134   c  is fixed at one end of the first shaft  134   b  away from the first cap  134   a . Therefore, the first fastener  134   c  and the first cap  134   a  fix the first pivot portion  131   a  and the second pivot portion  132   a  therebetween. 
     One of the first pivot portion  131   a  and the second pivot portion  132   a  includes a first base  132   d  and a second base  132   e  opposite to the first base  132   d , at least part of the other one of the first pivot portion  131   a  and the second pivot portion  132   a  is arranged between the first base  132   d  and the second base  132   e . In the embodiment, the second pivot portion  132   a  includes the first base  132   d  and the second base  132   e  opposite to the first base  132   d , and at least part of the first pivot portion  131   a  is arranged between the first and second bases  132   d  and  132   e . Each of the first and second bases  132   d  and  132   e  defines a pivot hole  132   c . The first pivot shaft  134  passes through the pivot hole  132   c  of the first base  132   d , the pivot hole  131   c  and the pivot hole  132   c  of the second base  132   e  to pivotably connect the first pivot portion  131   a  and the second pivot portion  132   a  together. At least part of the first pivot portion  131   a  is clamped and limited by the first base  132   d  and the second base  132   e , and the first pivot portion  131   a  and the second pivot portion  132   a  are pivotably connected by the first pivot shaft  134 , which ensures stability of the first bendable connection assembly  13  during a bending process. 
     The pivotable connection between the first pivot portion  131   a  and the second pivot portion  132   a  is not limited to above embodiments. There may be a variety of modified embodiments, as long as a bendable connection (or rotatable connection) between the first pivot portion  131   a  and the second pivot portion  132   a  can be realized. There are too many modified embodiments to list one by one. 
     In at least one embodiment, the first bendable connection assembly  13  may further includes a first pad  135  having a first through hole  135   a  and a second pad  136  having a second through hole  136   a . The other one of the first pivot portion  131   a  and the second pivot portion  132   a  defines two grooves  131   d  communicating with the second pivot hole  132   c  at two sides thereof respectively. In the embodiment, the first pivot portion  131   a  defines two grooves  131   d  communicating with the second pivot hole  132   c  at two sides thereof respectively. The first pad  135  and the second pad  136  are respectively accommodated in the two grooves  131   d . The first pivot shaft  134  passes through the second pivot hole  132   c  of the first base  132   d , the first through hole  135   a , the pivot hole  131   c  of the first pivot portion  131   a , the second through hole  136   a  into the pivot hole  132   c  of the second base  132   e  to connect the first pivot portion  131   a  and the second pivot portion  132   a  together. The first pad  135  and the second pad  136  helps to reduce pivot friction between the first pivot portion  131   a  and the second pivot portion  132   a , which facilitates bending of the first bendable connection assembly  13  and improves strength of the pivot connection between the first pivot portion  131   a  and the second pivot portion  132   a.    
     In at least one embodiment, the second base  132   e  defines a first accommodating groove  132   f  communicating with the second pivot hole  132   c  of the second base  132   e  at a side thereof away from the first base  132   d . The first fastener  134   c  is accommodated in the first accommodating groove  132   f  so that the first fastener  134   c  and the second base  132   e  can be integrated to a single part, which cannot interference with the second pivot portion  132   a  during the bending process. The first pivot portion  131   a  includes a body  131   e  and a limit portion  131   f  connected between the body  131   e  and the first connection portion  131   b . The body  131   e  is pivotably connected with the second pivot portion  132   a . The limit portion  131   f  together with the first connection portion  131   b  forms a step structure  131   g . The first connection portion  131   b  is accommodated in the first pipe  11  and the end of the first pipe  11  resists against the limit portion  131   f . During a telescopic process of the support structure  1 , the step structure  131   g  can limit the first pipe  11 . 
     The first bendable connection assembly  13  further includes at least one positioning member  137  arranged between the second connection portion  132  and an inner wall of the second pipe  12 . The positioning member  137  is configured to adjust friction between the second pipe and the second pivot portion  132   b . The at least one positioning member  137  can be arc-shaped.

     Referring to  FIGS. 1, 2 and 7 , the three states (retracted state, support state, and bent state) of the support structure  1  of the camera support device  100  will be illustrated. As shown in  FIG. 1 , when the support structure  1  is in the retracted state, the pipes  15 ,  12 ,  11  and  14  of the pipe assembly  10  can be retracted in turn, so that most of the plurality of pipes  15 ,  12 ,  11 ,  14  and  14   a  located above the second connecting pipe  15   a  are retracted in the lowest pipe  15   a . At this time, a support height of the support structure  1  is relatively small, which is convenient for storage, carrying, etc. of the camera support device  100 , It can also be applied to photographing or lighting by placing the camera support device  100  on the desktop. In particular, in the retracted state, the first pipe  11 , the second pipe  12  and the first bendable connection assembly  13  can be retracted into the lowest pipe  15   a , and the first pipe  11 , the second pipe  12  and the first bendable connection assembly  13  can further achieve effects of being hidden, not easy to be damaged and beautiful. 
     When the support height of the support structure  1  needs to be adjusted, at least part of the pipes of the pipe assembly  10  can be extended, so that the support height of the support structure  1  is increased. Specifically, as shown in  FIG. 2 , when the pipes are fully extended, the support structure  1  can reach the greatest support height. However, when it is not necessary to apply the highest support height, it can make part of the pipes partially extended or part of the pipes fully extended, without making all the pipes fully extend. 
     When it is necessary to adjust the support structure  1  so that the camera device on the holding structure  2  can aim at the object on the horizontal support surface (such as desktop and the ground), at least part of the second pipe  12  can be pulled out, the first pipe  11  can be pulled out of the second pipe  12 , and the first pivot part, the first pipe  11  and the connecting pipe assembly  14  connected with the first pipe  11  and the holding structure  2  connected with the first connecting pipe  14   a  can be bent by an external force. The first pivot part drives the first pipe  11 , the connecting pipe assemblies  14  connected to the first pipe and the holding structure  2  connected to the first connecting pipe  14   a  to rotate (can rotate towards either one of the left side or right side) relative to the second pivot part, the second pipe  12  and the second connecting pipe assembly  15 , so as to facilitate the camera device on the holding structure  2  to shoot objects on the horizontal support surface (such as desktop and the ground). At this time, the position of the holding structure  2  can also be adjusted by adjusting extension lengths of the first pipe  11 , the first connecting pipes  14 ,  14   a , etc; The height of the holding structure can further be adjusted by adjusting extension lengths of the second pipe  12  and the second connecting pipes  15  and  15   a.    
     Referring to  FIGS. 1, 2 and 7 , switch of the three states of the support structure  1  can be achieved by applying external forces to extend/retract the pipes or bend the first pipe  11 , the first connecting pipe assembly  14  relative to the second pipe  12 , the second connecting pipe assembly  15 . It is easy to operate, which should be understood by an ordinary person skilled in the art and is not repeated here. 
     It should be understood that, at each of the three states illustrated in  FIGS. 1, 2 and 7 , the angles of the holding structure  2  relative to the support structure  1  can be adjusted through the first bendable connection assembly so that the camera device supported on holding structure  2  of the camera support device  100  can shoot objects at different angles, positions. 
     In at least one embodiment, through the telescopic bendable support structure, besides telescopic structures are convenient for storage and carrying and the support height can be adjusted, the camera support device  100  can realize telescoping in addition to being bendable between the first pipe  11  and the second pipe  12  through the first bendable connection assembly  13 . Thus, it is convenient to adjust the support height and support angle of the holding structure, which is convenient for users to use in a variety of application scenarios, such as bending to adjust the position, height and angle of the lighting member and the electronic devices such as mobile phones on the holding structure, so as to improve the user experience. 
     In particular, when the camera support device  100  is in use, such as when the user uses the camera support device  100  during live broadcast, the camera (such as front camera or rear camera) of the camera device (such as a mobile phone) on the camera support device  100  can shoot the user&#39;s face or target position. At this time, the display surface of the camera device can be substantially parallel to the vertical direction. When it is further necessary to use the camera device on the camera support device  100  to shoot an object on a horizontal support surface, the first bendable connection assembly  13  can drive the first pivot part to bring the first pipe  11 , the first connecting pipe assembly  14 , the holding structure  2  and the camera device to rotate (e.g. rotate 90 degrees) relative to the second pivot part through the first bendable connection assembly  13 , so that the camera of the camera device (e.g. rear camera) can correspond to the object on the horizontal support surface, and the display screen of the camera device is located to facilitate the user to view the photographed object displayed on the display screen. At this time, the support height of the second connecting pipe assembly  15  of the pipe assembly  10  can also be adjusted to adjust a distance between the camera device and the object to be photographed, or a telescopic length of the first connecting pipe assembly  14  of the pipe assembly  10  can be adjusted so that the camera of the camera device can exactly correspond to the object to be photographed. Through the telescopic bendable support structure  1 , the camera support device  100  can be used in a variety of scenes, which can improve the user experience. 
     When the support structure  1  is in the retracted state, the pipes  15 ,  12 ,  11  and  14  of the pipe assembly  10  can be retracted in turn, so that most of the plurality of pipes  15 ,  12 ,  11 ,  14  and  14   a  located above the second connecting pipe  15   a  are retracted in the lowest pipe  15   a . At this time, a support height of the support structure  1  is relatively small, which is convenient for storage, carrying, etc. of the camera support device  100 , It can also be applied to photographing or lighting by placing the camera support device  100  on the desktop. In particular, in the retracted state, the first pipe  11 , the second pipe  12  and the first bendable connection assembly  13  can be retracted into the lowest pipe  15   a , and the first pipe  11 , the second pipe  12  and the first bendable connection assembly  13  can further achieve effects of being hidden, not easy to be damaged and beautiful.

The telescopic bendable support structure  1  includes a support state, bent state and retracted state, so that the camera device on the camera support device  100  can be in different heights, angles, etc. 
     In the retracted state, the first pipe  11 , the first pivot portion  131   a  and the second pivot portion  132   a  can be basically accommodated in the second pipe  12 , so that the volume of the support structure  1  can be minimized to the volume of the second pipe  12 . In the retracted state, the camera support device  100  can be placed on a desktop to support a camera device, which is especially for live broadcast.

     The following will combine with  FIGS. 14-17  to illustrate differences between the telescopic bendable support structure of the fourth embodiment and the telescopic bendable support structure of the first embodiment. 
     The first pipe  11  defines a first circular recessed portion  112 , and the first connection portion  131   b  defines at least one first circular positioning groove  131   m  configured to receive the circular recessed portion  112  so as to limit an axial position of the first connection portion  131   b  relative to the first pipe  11 .

An inner diameter of the bottom hole is greater than an outer diameter of the second rod  132   j  and is less than an outer diameter of the first rod  132   i . Therefore, the second rod  132   j  can pass through the bottom hole while an end of the first rod  132   i  connected with the second rod  132   j  resists against the bottom wall  133   c  of the auxiliary pipe  133 . The The elastic member  139  can be sleeved on the second rod  132   j  and resists against the bottom wall  133   c  of the auxiliary pipe  133 .

The second gear portion  133   b  can be meshed with the first gear portion  132   h . When an external force is applied on the second pivot part  132  to rotate the second pivot part  132  relative to the auxiliary pipe  133 , the auxiliary pipe  133  moves towards the second pipe to compress the elastic member  139 , so that the second gear portion  133   b  is detached from the first gear portion  132   h . When the second pivot part  132  moves to a desired angle and the external force is released, the elastic member  139  restores to force the auxiliary pipe  133  to move towards the second pivot part  132  until the second gear portion  133   b  meshes with the first gear portion  132   h . In this way, the first pipe  11 , the first bendable connection assembly  13  can rotate around an extension direction thereof relative to the auxiliary pipe  133  and the second pipe  12  at one end of the second pipe  12 .
