CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation of international PCT application serial no. PCT/CN2021/127634, filed on Oct. 29, 2021. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. 
    
    
     TECHNICAL FIELD 
     The present application relates to the technical field of a mounting rack, and particularly to a bracket. 
     BACKGROUND ART 
     A bracket is often mounted on a wall or ceiling, which is a basic component for supporting objects. When in use, it is generally matched with rod components, and the rod components are connected to adjacent brackets, so that the rod is hung in the air. This kind of rod is generally used for items such as hanging curtains, washing supplies, projection curtains. 
     There are generally two connection ways between the bracket and the rod component. 
     The first one is locking fixing. However, the rod components are often more easily damaged than brackets, for example, bending, deforming or breaking. For example, in the case of hanging the curtain, the curtain often needs to be cleaned and changed regularly, and thus such bracket is not convenient for use since it is installed in the wall or ceiling and cannot be detached conveniently. 
     The second one is a bracket provided with a groove on the surface thereof, in which the two ends of the rod are provided Although this way can achieve the purpose of replacing the rod components, the rod components tend to loosen relative to the grooves, having a poor stability. 
     SUMMARY 
     In order to enable a rod component to be mounted on/detached from a bracket while ensuring sufficient stability, the present application provides a bracket. 
     A bracket provided in the present application adopts the following technical solution: 
     a bracket including a base for external connection and a hooking part connected with the base, in which a bending portion of the hooking part forms a groove, a groove wall connected the groove with the base is provided with a mounting hole, the mounting hole is provided with a damping element, and a damping portion of the damping element is located in the groove. 
     In the above technical solution, the base can be externally connected to the wall or ceiling, and the damping element can be selected depending on the specification of the rod components. The damping element can be movably installed into the mounting hole or fixed through the mounting hole in advance. During the mounting process, taking an upward opening of the groove as an example, after the rod component is pressed into the groove from top to bottom, the damping element cannot move up and down due to the limitation of the mounting hole, thus the damping element will stop the rod component from moving up by damping. In this way, disassembling can be realized only by applying a force big enough to the rod component. This achieves the effect that the rod component can be mounted on or detached from the bracket, while ensuring sufficient stability after mounting. 
     Optionally, the mounting hole penetrates through the surface of the hooking part. The damping element includes a tailstock and a damping head fixedly connected with each other. The tailstock penetrates through the mounting hole, and the tailstock is provided with an anti-detachment structure to prevent the tailstock from falling off the mounting hole. 
     In the above technical solution, detachable mounting of the damping element can be realized. The damping element can be replaced according to the specification of the rod component, no matter whether the anti-detachment structure can be detached directly or destructively. 
     Optionally, the anti-detachment structure includes at least one elastic inclining block fixed at a side wall of the tailstock, in which a surface of the inclining block away from the damping head is an inclined guiding surface. When the tailstock is mounted in the mounting hole, the inclined guiding surface contacts the hole wall of mounting hole earlier than other surfaces of the inclining block. 
     In the above technical solution, the tailstock can be directly inserted in the mounting hole. During this process, the inclined guiding surface will provide a guidance and be deformed. 
     After the tailstock is in place, the deformation will be restored, and the inclining block lacking guidance will prevent the tailstock from disengagement. 
     Optionally, a surface of the inclining block near the damping head is a stopping surface, and an acute angle between the stopping surface and a side wall of the tailstock exceeds an acute angle between the inclined guiding surface and the side wall of the tailstock by at least 20°. 
     In the above technical solution, firstly, an angle difference between the stopping surface and the inclined guiding surface represents a degree of easiness for deformation by pressing, that is, easy to mount but difficult to detach, so that the stability after mounting can be ensured. Secondly, the angel between the stopping surface and the tailstock is an acute angle. On the one hand, the tailstock can be pulled out upon the applying of a force big enough; and, on the other hand, during inserting, the stopping surface will press the damping head against the inner wall of the groove during the restoring of the inclined block, so as to improve the overall stability of the damping element. 
     Optionally, the surfaces of the damping head close to and away from the tailstock are arc surfaces, which bulge to the side away from the tailstock. An elastic cushion block is fixed at one side of the damping head close to the tailstock, and abuts against a groove wall of the groove, and at least one of two arc-shaped ends of the damping head abuts against the groove wall of the groove. 
     In the above technical solution, the elastic cushion block and the damping head can adaptively achieve abutting balance with the inner wall pile of the groove. On the one hand, it can achieve a sufficient stability and reduce the shaking of the damping element, and, on the other hand, when the rod components are pressed in, it can improve the amount of elastic deformation of the damping head and improve the damping effect. 
     Optionally, the surfaces of the damping head close to and away from the tailstock are multi-segment arc surfaces, and all of the arc surfaces of the damping head bulge to a side away from the tailstock. An arc surface of the damping head can be divided into a primary arc portion and a secondary arc portion. A connection portion between the groove wall of the groove and the base assumes an arc surface. One end of the primary arc portion abuts against the side wall of the groove, and the end of the primary arc portion connected with the secondary part abuts against the arc surface of the groove wall of the groove connected with the base. All the ends of the secondary arc portion abut against the arc surface connected between the groove wall of the groove and the base body. A side wall of the groove away from the base is provided with a convex portion, and the convex portion faces a connecting portion of the multi-segment arc surfaces of the damping head. 
     In the above technical solution, when the rod component is pressed against the surface of the damping head, an end of the primary arc portion connected with the primary arc portion and the secondary arc portion will be displaced and deformed outward under the guidance of the arc transition portion between the groove wall of the groove and the base, so as to provide a better avoidance for installing the rod component. The abutting connection of the other end of the secondary arc portion provides elastic structural support to avoid excessive deformation. After the rod component is installed into the groove, if it is forced to fall off, the portion of the primary arc portion towards the bottom of the groove will be pressed towards the opening of the groove, so that the middle portion of the primary arc portion toward the groove relative to the mounting hole, and the rod component will be easily stopped by the damping head. Hence, a simple-to-install and difficult-to-separate structure for a rod can be formed, providing the rod component with convenient mounting and higher stability. In addition, the convex portion serves an auxiliary function since the presence thereof will force the rod component to squeeze both the primary arc portion and the secondary part at the same time when being detached. 
     Optionally, the two opposite side walls of the tailstock are respectively provided with a limiting column. The mounting hole includes a main hole portion for the tailstock to pass through and a branch hole portion for the limiting column to pass through, and the number of the secondary holes is same as that of the limiting columns. 
     In the above technical solution, a limitation can be realized by rotation after the tailstock and the limiting column pass through the mounting hole. The specific rotation degree can be set according to the position of the limiting column relative to the tailstock. 
     Optionally, the mounting hole is a rectangular hole, a long side of the rectangle of the mounting hole is in the same direction as that of an axis of the hooking part. The projection of the tailstock along the long direction is of polygon, the polygon has an even number of sides. The number of sides of polygon is at least six, and the tailstock is made of elastic material. When the tailstock is in a final assembled state of the damping element and the hooking part, the two opposite faces of the tailstock are fitted with the two opposite and nearest hole walls of the mounting hole. 
     In the above technical solution, because the hooking part is an arc structure as a whole, in the case of an upward opening of the groove, when the length of the limiting column is in a horizontal direction, a portion of the limiting column abutting against an outer surface of the hooking part can be regarded as a straight line, and when the length of the limiting column is in an upward direction, a portion of the limiting column abutting against the outer surface of the hooking part can be regarded as a curve. Therefore, after the tailstock and the limiting column are inserted from the mounting hole, the rotation of the tailstock changes the orientation of the limiting column rotates from a horizontal direction to a vertical direction. In this process, the tailstock will also be further tightened so that the damping head can closely fit with the inner wall of the groove. In addition, in the process of rotation, since the tailstock is polygonal and the surface thereof fits with the hole wall of the mounting hole, the tailstock is rotated mainly depending on the elastic deformation of the tailstock. After the rotation is completed, the tailstock will not be easy to deflect due to the limitation provided by its shape, so as to ensure a structural stability during use. 
     Optionally, the tailstock is provided with a sliding slot on other opposite surfaces other than that provided with the limit column. The opening width of the sliding slot on the surface of the tailstock is less than the width of the inner cavity of the sliding slot. A side of the sliding slot close to the damping element is provided with an inlet slot, and the sliding slot is slidably connected with a filling block which can be used to fill the gap between the tailstock and the mounting hole. A glue filling slot laterally penetrating through the tailstock along the tailstock is recessed between the sliding slot and the inlet slot. 
     In the above technical solution, after the tailstock is rotatably installed in place, the filling block can be inserted through the inlet slot, then move along the sliding slot and fill the gap between the tailstock and the mounting hole. Therefore, the tailstock cannot rotate, and the tailstock cannot move in the direction away from the mounting hole due to the restriction of the limiting column. After the filling block is installed, a solidifiable glue can be injected into the glue filling slot from the side of the tailstock. After the solidifiable glue solidifies, since the glue filling slot is laterally positioned on the sliding path of the sliding block, it can play a good limiting role with sufficient strength. When the damping element is desired to be detached, a stick or needle smaller than the glue filling slot or the glue filling slot can be used to eject out the solidifiable glue. 
     Optionally, the shape of the mounting hole is an oval hole. An oval long axis of the mounting hole is in the same direction as that of an axis of the hooking part. The tailstock is an oval cylinder, the oval long axis of the tailstock is shorter than the oval long axis of the mounting hole, and the tailstock is elastic. The long axis length of the tailstock is sufficient to be reduced to be consistent with the short axis length of the mounting hole within the elastic deformation range. The limiting column is fixed in the area where the short axis of the tailstock is located. 
     In the above technical solution, for installation, firstly, the oval short edge of the tailstock is moved corresponding to the oval short edge of the mounting hole until the limiting column touches the inner wall of the groove. Then the tailstock is rotated to elastically deform the tailstock, and the limiting column falls into a position where it can pass through the mounting hole. Then, the limiting column is inserted into the mounting hole along with the tailstock and passes through the mounting hole. In this state, the tailstock has the elastic force of reverse rotation for restoring, and can be released or manually reversely rotated. In this way, the limiting column will abut against a surface of the hooking part far away from the damping head, playing the role of limiting and preventing detachment. 
     In summary, the present application includes at least one of the following beneficial technical effects. 
     1. The damping element can be selected depending on the specification of the rod components. The damping element can be movably installed into the mounting hole or fixed through the mounting hole in advance. During the mounting process, taking an upward opening of the groove as an example, after the rod component is pressed into the groove from top to bottom, the damping element cannot move up and down due to the limitation of the mounting hole, thus the damping element will stop the rod component from moving up by damping. In this way, disassembling can be realized only by applying a force big enough to the rod component. This realizes the effect that the rod component can be mounted on or detached from the bracket, while ensuring sufficient stability after mounting. 
     2. On the one hand, the tailstock can be pulled out upon the applying of a force big enough; and, on the other hand, during inserting, the stopping surface will press the damping head against the inner wall of the groove during the restoring of the inclined block, so as to improve the overall stability of the damping element. 
     3. When the rod component is pressed against the surface of the damping head, an end of the primary arc portion connected with the secondary arc portion will be displaced and deformed outward under the guidance of the arc transition portion between the groove wall of the groove and the base, so as to provide better avoidance for installing the rod component. Abutting connection of the other end of the secondary arc portion provides elastic structural support to avoid excessive deformation. After the rod component is installed into the groove, if it is forced to fall off, the portion of the primary arc portion towards the bottom of the groove will be pressed towards the opening of the groove, so that the middle portion of the primary arc portion is pulled toward the groove relative to the mounting hole to, and the rod component will be easily stopped by the damping head. Hence, a simple-to-install and difficult-to-separate structure for a rod can be formed, providing the rod component with convenient mounting and higher stability.

     DETAILED DESCRIPTION 
     The present application is further described in detail below in combination with the  FIGS.  1 - 8   . 
     The present application discloses a bracket. 
     Embodiment 1 
     Referring to  FIG.  1    and  FIG.  2   , a bracket includes a base  1  and a hooking part  2 , and the base  1  is integrated with the hooking part  2 . In this embodiment, the base  1  and the hooking part  2  are made of mental material. In this embodiment, the base  1  is L-shaped, and one of the L-shaped surfaces is provided with one or more holes for connecting with a wall or ceiling through a screw bolt. In other embodiments, it also can be of other shapes adapted to a space corresponding to the wall or ceiling, such as V-shape. In this embodiment, the hooking part  2  is U-shaped, and the L-shaped end of the base  1  without a hole is connected with the U-shaped end of the hooking part  2 . In other embodiments, the hooking part  2  can be of other shapes which can clamp a rod, such as C-shape, V-shape or the like. 
     A curved portion of the hooking part  2  forms a groove  21 , and the groove wall of the groove  21  connected with the base  1  is provided with a mounting hole  22  which penetrates through the U-shaped surface of the hooking part  2 . 
     The mounting hole  22  is provided with a damping element  3  which includes a tailstock  31  and a damping head  32 . The tailstock  31  penetrates through the mounting hole  22 , and the damping head  32  enters the groove  21 . In this embodiment, the tailstock  31  and the damping head  32  are integrally injection molded, and the materials of the tailstock  31  and the damping head  32  can be the same or different. If different, two-color injection molding is adopted, and the material damping factor of the damping head  32  is greater than that of the tailstock  31 . This embodiment takes the same material as an example. 
     Surfaces of the damping head  32  close to and away from the tailstock  31  are arc surfaces, and all of the arc surfaces of the damping head  32  bulge toward a side away from the tailstock  31 . A damping pattern  321  is provided on a surface of the damping head  32  away from the tailstock  31 . An elastic cushion block  33  is fixed on one side of the damping head  32  close to the tailstock  31 , the elastic cushion block  33  abuts against a groove wall of the groove  21 , and at least one of the two arc-shaped ends of the damping head  32  abuts against the groove wall of the groove  21 . After installing damping portion  3 , both ends of the damping head  32  abut against the groove wall of the groove  21 , so that only elastic deformation will occur during the installation of the rod component, avoiding jumping. 
     Referring to  FIG.  2    and  FIG.  3   , the tailstock  31  is provided with an anti-detachment structure  4  to prevent the tailstock  31  from separating from the mounting hole  22 . In this embodiment, the anti-detachment structure  4  includes two inclining blocks  41  fixed at opposite side walls of the tailstock  31 , and the inclining blocks  41  are elastic. A surface of the inclining block  41  away from the damping head  32  is an inclined guiding surface  411 . When the tailstock  31  is mounted in the mounting hole  22 , the inclined guiding surface  411  contacts the hole wall of the mounting hole  22  earlier than other surfaces of the inclining block  41  to provide direction guiding, elastically deforms, penetrates through the mounting hole  22 , and restore its shape. With this, the surface of the inclining block  41  close to the damping head  32  abuts against the surface of the hooking part  2  to prevent the tailstock  31  from detachment. A surface of the inclining block  41  near the damping head  32  is a stopping surface  412 , and the acute angle between the stopping surface  412  and the side wall of the tailstock  31  at least exceeds the acute angle between the inclined guiding surface  411  and the side wall of the tailstock  31  by 20° . In this embodiment, the mentioned angle relative to the guide inclined plane  411  is 30°, and the mentioned angle relative to the stopping surface  412  is 75°. Therefore, after the inclining block  41  penetrates through the mounting hole  22 , the stopping surface  412  can further tighten the damping head  32  to press the damping head  32  against the inner wall of the groove  21 , playing the role of anti-detachment. If a detachment is desired, a force sufficient to elastically deform the stopping surface  412  and pull the tailstock  31  out of the hooking part  2  can be applied. After pulling out, the damping element  3  can be reinstalled and used. 
     In this embodiment, the inclining block  41 , the elastic cushion block  33  and the tailstock  31  are integrally injection molded. 
     The implementation principle of Embodiment 1 is: 
     The tailstock  31  of the damping element  3  can be inserted into the mounting hole  22  of the hooking part  2 , during which the damping element  3  is automatically pressed against the surface of the groove  21  of the hooking part  2 . Then the base  1  will be mounted on a wall and ceiling. A rod component can be mounted in two or more the brackets, which is not easy to fall off since it will be limited by the damping head  32  after being clamped in the groove  21 . 
     After the rod component is detached forcefully, if it is desired to replace a rod with different specifications, the damping element can also be pulled out and different damping elements can be mounted, for achieving the same damping effect. 
     Embodiment 2 
     Referring to  FIG.  4   , the difference between this embodiment and Embodiment 1 is that, the surfaces of the damping head  32  close to and away from the tailstock  31  are multi-segment arc surfaces, and all the arc surfaces of the damping head  32  bulge toward a side away from the tailstock  31 . A connection portion between the groove wall of the groove  21  and the base  1  assumes an arc surface. An arc surface of the damping head  32  is divided into a primary arc portion  322  and a secondary arc portion  323 . One end of the primary arc portion  322  abuts against the groove wall of the groove  21 , and the end of the primary arc portion  322  connected with the secondary arc portion  323  abuts against the arc surface of the groove wall of the groove  21  connected with the base  1 . All the ends of the secondary arc portion  323  abut against the arc surface connected between the groove wall of the groove  21  and the base body  1 . A side wall of the groove  21  away from the base is provided with a convex portion  23 , and the convex portion  23  faces a connecting portion between the multi-segment arc surfaces of the damping head  32 . 
     In this way, when the rod component is pressed against the surface of the damping head  32 , an end of the primary arc portion  322  connected with the secondary arc portion  323  will be displaced and deformed outward under the guidance of the arc transition portion between the groove wall of the groove  21  and the base  1 , so as to provide better avoidance for installing the rod component. After the rod component is installed into the groove  21 , if it is forced to fall off, the portion of the primary arc portion  322  towards the bottom of the groove will be pressed towards the opening of the groove  21 , so that the middle portion of the primary arc portion  322  is pulled toward the groove  21  relative to the mounting hole  22 , and the rod component will be easily stopped by the damping head  32 . Hence, a simple-to-install and difficult-to-separate structure for a rod can be formed. 
     Embodiment 3 
     Referring to  FIG.  5    and  FIG.  6   , the difference between this embodiment and Embodiment 1 is that, the two opposite side walls of the tailstock  31  are respectively provided with a limiting column  42 , the mounting hole  22  includes a main hole portion (not shown) for the tailstock  31  to pass through and a branch hole portion (not shown in the figure) for the limiting columns  42  to pass through, and the number of the secondary holes is equal to that of the limiting columns  42 . The main hole portion and the branch hole portion can be holes with different cross-sectional shapes respectively. For example, the main hole portion is a square hole and the branch hole portion is a circular hole. Alternatively, they can jointly form a regular pattern. For example, a square hole can be divided into a main hole portion for the tailstock  31  to pass through and a branch hole portion for the limiting column  42  to pass through. In this embodiment, the mounting hole  22  is a rectangular hole as an example. A long side direction of the rectangle of the mounting hole  22  is in the same direction as the axis direction of the hooking part  2 . 
     The tailstock  31  made of elastic material. the projection of the tailstock  31  along the long direction is of polygon, the polygon has an even number of sides. The number of sides of polygon is at least six. In this embodiment, the tailstock  31  is an octagonal prism as an example. In a final assembled state of the damping element  3  and the hooking part  2 , the two opposite faces of the tailstock  31  are fitted with the two opposite and nearest hole walls of the mounting hole  22 . 
     Taking an upward opening of the groove  21  as an example, when the length of the limiting column  42  is in a horizontal direction, a portion of the limiting column  42  abutting against a side surface of the hooking part  2  can be regarded as a straight line, and when the length of the limiting column  42  is in an upward direction, a portion of the limiting column  42  abutting against a side surface of the hooking part  2  can be regarded as a curve. Therefore, after the tailstock  31  and the limiting column  42  are inserted from the mounting hole  22 , the rotation of the tailstock  31  changes the orientation of the limiting column  42  from a horizontal direction to a vertical direction. In this process, the tailstock  31  will also be further tightened so that the damping head  32  can closely fit with the inner wall of the groove  21 . In addition, in the process of rotation, since the tailstock  31  is polygonal and the surface thereof fits with the hole wall of the mounting hole  22 , the tailstock  31  is rotated mainly depending on the elastic deformation of the tailstock  31 . After the rotation is completed, its shape can prevent reverse rotation. 
     Embodiment 4 
     Referring to  FIG.  7   , the difference between this embodiment and Embodiment 3 is that, the tailstock  31  is provided with a sliding slot  311  on other opposite surfaces other than that provided with the limit column  42 . The opening width of the sliding slot  311  on the surface of the tailstock  31  is less than the width of the inner cavity of the sliding slot  311 . A side of the sliding slot  311  close to the damping element  3  is provided with an inlet slot  312 , and the sliding slot  311  is slidably connected with a filling block  34  which can be used to fill the gap between the tailstock  31  and the mounting hole  22 . A glue filling slot  313  laterally penetrating through the tailstock  31  along the tailstock  31  is recessed between the sliding slot  311  and the inlet slot  312 . 
     After the tailstock  31  is rotatably installed in place, the filling block  34  can be inserted through the inlet slot  312 , then move along the sliding slot  311  and fill the gap between the tailstock  31  and the mounting hole  22 . Therefore, the tailstock  31  cannot rotate, and the tailstock  31  cannot move in the direction away from the mounting hole  22  due to the restriction of the limiting column  42 . After the filling block  34  is installed, a solidifiable glue can be injected into the glue filling slot  313  from the side of the tailstock  31 . After the solidifiable glue solidifies, since the glue filling slot  313  is laterally positioned on the sliding path of the sliding block, it can play a good limiting role with sufficient strength. When the damping element  3  is desired to be detached, a rod or needle smaller than the glue filling slot  313  or the glue filling slot  313  can be used to eject out the solidifiable glue. 
     In this embodiment, the elastic cushion block  33  can have a reduced thickness or directly omitted to provide convenience for providing the sliding slot  311 . In other embodiments, the inlet slot  312  and the glue filling slot  313  can be provided at one end away from the damping head  32 , so that the filling block  34  can be inserted into the sliding slot  311  from a side of the hooking part  2  (not shown) away from the groove  21 (not shown), and the thickness of the corresponding elastic cushion block  33  can remained unchanged. 
     Embodiment 5 
     Referring to  FIG.  8   , the difference between this embodiment and Embodiment 3 is that, the mounting hole  22  is an oval hole. The oval long axis of the mounting hole  22  is in the same direction as the axis of the hooking part  2 . The tailstock  31  is an oval cylinder, the oval long axis of the tailstock  31  is shorter than the oval long axis of the mounting hole  22 , the oval short axis of the tailstock  31  coincides with the oval short axis of the mounting hole  22 , and the tailstock  31  is elastic. The long axis length of the tailstock  31  is sufficient to be reduced to be consistent with the short axis length of the mounting hole  22  within the elastic deformation range. The limiting column  42  is fixed in the area where the short shaft of the tailstock  31  is located. 
     In this embodiment, the oval short axis of the tailstock  31  coincides with the oval short axis of the mounting hole  22 . 
     For installation, firstly, the oval short edge of the tailstock  31  is moved corresponding to the oval short edge of the mounting hole  22  until the limiting column  42  touches the inner wall of the groove  21 . Then the tailstock  31  is rotated to elastically deform the tailstock  31 , and the limiting column  42  falls into a position where it can pass through the mounting hole  22 . Then, the limiting column  42  is inserted into the mounting hole  22  along with the tailstock  31  and passes through the mounting hole  22 . In this state, the tailstock  31  has the elastic force of reverse rotation for restoring, and can be released or manually reversely rotated. In this way, the limiting column  42  will abut against a surface of the hooking part  2  far away from the damping head  32 , playing the role of limiting and preventing detachment. 
     The above are the preferred embodiments of the present application, which are not intend to limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
