[0034] This embodiment relates to a folding bracket, which is mainly used to connect with functional devices such as a fan head and a fill light to support and fix the functional devices when they are in use. The folding bracket can be stored and folded for easy carrying or use.

[0035] See also Figures 1 to 3 In one embodiment, the folding bracket includes: a clamping device 1 and a bracket assembly 2. The clamping device 1 is connected to the bracket assembly 2. Obviously, the clamping device 1 is provided on the bracket assembly 2, which not only enables the bracket assembly 2 to be clamped with other objects through the clamping device 1, thereby facilitating the use of functional devices such as fan heads or fill lights on the bracket assembly 2, but also the clamping device 1 can also serve as a base, so that the functional devices assembled on the bracket assembly 2 can be placed on a desktop or table for use, thereby improving the diversity of the use scenarios of the bracket assembly 2.

[0036] In one embodiment, the clamping device 1 includes: a first clamping body 11 , a second clamping body 12 and a fastening assembly 13 .

[0037] Specifically, the first clamping body 11 has a first clamping end 111. The second clamping body 12 has a second clamping end 121. The first clamping body 11 and the second clamping body 12 are rotatably assembled. A portion of the fastening assembly 13 is disposed on the first clamping body 11, and another portion is disposed on the second clamping body 12. The fastening assembly 13 confines the clamped object between the first clamping body 11 and the second clamping body 12, and brings the first clamping end 111 and the second clamping end 121 close to each other, thereby clamping the clamped object. By fixing the first clamping end 111 and the second clamping end 121 by the fastening assembly 13, on the one hand, the stability of the clamping between the first clamping end 111 and the second clamping end 121 can be improved, so that the first clamping end 111 and the second clamping end 121 are clamped more firmly; on the other hand, the clamped object can be prevented from being separated from the clamping device 1, thereby preventing the folding bracket and the functional device assembled thereon from falling directly due to the loosening of the clamping device 1.

[0038] In one embodiment, a clamping groove 100 is provided on the end surface of the first clamping body 11 close to the second clamping body 12 and on the end surface of the second clamping body 12 close to the first clamping body 11. The clamping groove 100 is provided close to one side of the fastening assembly 13. When the clamping device 1 clamps other objects, the clamped object is located between the first clamping body 11 and the second clamping body 12 and is confined in the clamping groove 100, so that the clamping device 1 clamps more stably, which is conducive to the use of the folding bracket.

[0039] In one embodiment, the clamping groove 100 is provided with two groups, namely a first clamping groove 1001 and a second clamping groove 1002. Figure 2 The slot size D1 of the first clamping slot 1001 is smaller than the slot size D2 of the second clamping slot 1002, and the first clamping slot 1001 is closer to the fastening assembly 13 than the second clamping slot 1002. The first clamping slot 1001 and the second clamping slot 1002 with different slot sizes are provided so that the clamping device can be used for clamping rod-shaped objects of different sizes.

[0040] In this embodiment, two first clamping grooves 1001 are provided, and are respectively located on the first clamping body 11 and the second clamping body 12. The two first clamping grooves 1001 can clamp the object by cooperating with each other, and can effectively prevent the clamped object from escaping from the clamping device 1. Similarly, two second clamping grooves 1002 are also provided, and are also respectively located on the first clamping body 11 and the second clamping body 12. The two second clamping grooves 1002 can also clamp the object by cooperating with each other, and can effectively prevent the clamped object from escaping from the clamping device 1.

[0041] It should be noted that the slot size D1 of the first clamping slot 1001 is smaller than the slot size D2 of the second clamping slot 1002, and the cross section of the first clamping slot 1001 is in the shape of an arc, so that the first clamping slot 1001 has better clamping stability for a rod-shaped clamp with a circular cross section. The depth of the second clamping slot 1002 (the distance from the slot to the lowest point of the slot bottom) is greater than the depth of the first clamping slot 1001, and the cross section of the second clamping slot 1002 is in the shape of an ellipse, so that the second clamping slot 1002 has better clamping stability for a rod-shaped clamp with an oblate cross section.

[0042] It should also be noted that the folding bracket of this embodiment is mainly used for a baby stroller fan (i.e., the functional device is a baby stroller fan head), so that the baby stroller fan can be clamped on the rod body of the baby stroller for use. Since the main types of baby stroller rod bodies are cylindrical, oblate cylindrical or elliptical, the cylindrical rod body is suitable for the first clamping groove 1001 on the clamping device 1 for limiting, so that the folding bracket is more stable when in use; and the oblate cylindrical or elliptical rod body is suitable for the second clamping groove 1002 on the clamping device 1 for limiting, thereby improving the stability of the folding bracket when in use. In this way, the folding bracket provided with the clamping device 1 having the first clamping groove 1001 and the second clamping groove 1002 is more convenient for the use of the baby stroller.

[0043] See also Figures 4 to 7 In one embodiment, a clamping rubber pad 14 is provided in the first clamping groove 1001, so that the friction between the clamped object and the first clamping body 11 and the second clamping body 12 is greater, which is more conducive to clamping the clamping device 1 and the clamped object and ensures the stability of the clamping.

[0044] In one embodiment, a support pad 112 is provided on the end surface of the first clamping body 11 away from the second clamping body 12. When the folding bracket is placed on a desktop or table for use, the support pad 112 can increase the friction between the folding bracket and the desktop or table, thereby improving the stability of the folding bracket support.

[0045] In one embodiment, the clamping device 1 further includes a first elastic member 15 and a rotating member 16. The first elastic member 15 is disposed between the first clamping body 11 and the second clamping body 12. Specifically, one end of the first elastic member 15 abuts against the side of the first clamping body 11 away from the first clamping end 111, and the other end is connected to the side of the second clamping body 12 away from the second clamping end 121. The first elastic member 15 makes the end of the first clamping body 11 away from the first clamping end 111 and the end of the second clamping body 12 away from the second clamping end 121 move away from each other, so that the first clamping end 111 and the second clamping end 121 are close to each other to clamp the clamped object. The rotating member 16 penetrates the first clamping body 11 and the second clamping body 12, so that the first clamping body 11 and the second clamping body 12 are rotated and assembled.

[0046] Please continue reading Figures 4 to 7 In one embodiment, an L-shaped limit strip 113 is provided on the side of the first clamping body 11 away from the first clamping end 111, and one end of the first elastic member 15 abuts against the L-shaped limit strip 113. A plurality of clamping strips 122 are provided on the side of the second clamping body 12 away from the second clamping end 121, and the plurality of clamping strips 122 are grouped in pairs. The two clamping strips 122 in the same group are parallel to each other, and a limit gap is formed between the two parallel clamping strips 122, and the other end of the first elastic member 15 is confined in the limit gap. In this embodiment, four clamping strips 122 are provided, and the four clamping strips 122 are divided into two groups to define the two ends of the first elastic member 15 close to the second clamping body 12.

[0047] In one embodiment, a first mounting ear 114 is provided on the first clamping body 11 near the second clamping body 12, and a second mounting ear 123 is provided on the second clamping body 12 near the first clamping body 11. A through hole 101 is provided on both the first mounting ear 114 and the second mounting ear 123, and a rotating shaft portion 161 is provided on the end surface of one side of the rotating member 16, and the rotating shaft portion 161 is passed through and clamped in the through hole 101, so that the first clamping body 11 and the second clamping body 12 are rotatably assembled.

[0048] Please go back Figures 2 to 4 In one embodiment, the fastening assembly 13 includes: a lock buckle 131 and a strap 132. The lock buckle 131 is connected to the first clamping body 11. The strap 132 is connected to the second clamping body 12. The strap 132 passes over the clamped object and cooperates with the lock buckle 131, so that the first clamping end 111 and the second clamping end 121 cooperate to clamp the clamped object, and the first clamping end 111 and the second clamping end 121 are locked in a clamped state.

[0049] In one embodiment, the lock buckle 131 includes a fixed section 1311 and a curved extension section 1312. The fixed section 1311 is connected to the first clamping end 111 and extends to a side away from the first clamping end 111. The curved extension section 1312 is connected to an end of the fixed section 1311 away from the first clamping end 111. The curved extension section 1312 extends to a side away from the second clamping body 12 and forms an angle with the fixed section 1311.

[0050] In this embodiment, there is a deviation angle a between the fixed section 1311 and the horizontal line (see Figure 2), so that the fixed section 1311 and the first clamping end 111 have a smooth transition, so that the first clamping end 111 can clamp an object. One end of the curved extension section 1312 is connected to the fixed section 1311 through a chamfer transition, and the other end extends vertically downward, so that the curved extension section 1312 has a portion parallel to the side wall of the first clamping body 11. In this way, the angle between the fixed section 1311 and the curved extension section 1312 is an obtuse angle, so that the connection between the lock buckle 131 and the strap 132 is more stable. In other embodiments, the angle formed between the curved extension section 1312 and the fixed section 1311 can also be an acute angle, as long as the lock buckle 131 is able to cooperate with the strap 132 and lock the strap 132.

[0051] In one embodiment, the strap 132 is a flexible strap that can be bent and buckled with the buckle 131. The strap 132 is provided with a buckle hole 1321, and a plurality of buckle holes 1321 are provided and penetrate the strap 132. The plurality of buckle holes 1321 are evenly spaced along the length direction of the strap 132. In this embodiment, there are 7 buckle holes 1321, and all of the seven buckle holes 1321 are waist-shaped holes.

[0052] Please continue reading Figures 4 to 7 In one embodiment, a receiving groove 124 is provided on the end surface of the second clamping body 12 on one side close to the bracket assembly 2, and the strap 132 can be accommodated in the receiving groove 124 to facilitate the storage of the strap 132 and improve the overall aesthetics of the clamping device 1.

[0053] In one embodiment, a limiting column 1322 is provided on the end surface of the strap 132 near the bottom of the receiving slot 124. A limiting hole 1241 is provided on the bottom of the receiving slot 124 away from the second clamping end 121. When the strap 132 is received, the limiting column 1322 cooperates with the limiting hole 1241 to firmly limit the strap 132 in the receiving slot 124, so as to prevent the strap 132 from escaping from the receiving slot 124.

[0054] In this embodiment, the limiting column 1322 is made of a flexible material, and an annular protrusion 13221 is provided on the outer side wall of the limiting column 1322. Specifically, the end of the limiting column 1322 away from the binding band 132 is set to be spherical, so that the limiting column 1322 can penetrate into the limiting hole 1241. The radial dimension of the annular protrusion 13221 is slightly larger than the radial dimension of the limiting hole 1241. When the limiting column 1322 cooperates with the limiting hole 1241, a force is applied to the binding band 132 to make the annular protrusion 13221 pass through the limiting hole 1241. When the annular protrusion 13221 passes through the limiting hole 1241, it is elastically deformed by the extrusion of the limiting hole 1241, and the annular protrusion 13221 returns to its original state after passing through the limiting hole 1241. In this way, the limiting column 1322 can be limited in the limiting hole 1241 through the cooperation between the annular protrusion 13221 and the limiting hole 1241, thereby preventing the binding belt 132 from escaping from the receiving groove 124.

[0055] In one embodiment, the fastening assembly 13 further includes a hinge shaft 133. The hinge shaft 133 passes through the end of the strap 132 close to the second clamping end 121, and the two ends of the hinge shaft 132 are respectively connected to the two side walls of the receiving groove 124 extending along the length direction thereof, so as to rotatably assemble the strap 132 and the second clamping body 12.

[0056] In one embodiment, a relief groove 1242 is provided at the bottom of the receiving groove 124 near the second clamping end 121 , so that the hinged end of the strap 132 has enough movable space, thereby facilitating the strap 132 to rotate relative to the second clamping body 12 .

[0057] In one embodiment, the avoidance groove 1242 penetrates the second clamping body 12 , and an n-shaped notch 12421 is disposed on the side wall of the avoidance groove 1242 , and the hinge shaft 133 is inserted into the n-shaped notch 12421 from the first clamping body 11 .

[0058] In one embodiment, two n-shaped notches 12421 are provided, and the two ends of the hinge shaft 133 are respectively installed in two different n-shaped notches 12421. Abutment platforms 141 are protrudingly provided on the end surface of the clamping rubber pad 14 installed on the second clamping body 12 away from the first clamping body 11, and two abutment platforms 141 are provided. The clamping rubber pad 14 is fixedly assembled with the second clamping body 12 by gluing. When the clamping rubber pad 14 is fixedly attached to the second clamping body 12, the two abutment platforms 141 enter the avoidance groove 1242 from the first clamping groove 1001 and respectively abut against the openings of the two n-shaped notches 12421, thereby confining the hinge shaft 133 in the n-shaped notch 12421.

[0059] In one embodiment, a mounting portion 125 is provided on one side of the second clamping body 12 close to the bracket assembly 2 , and the bracket assembly 2 is rotatably assembled with the clamping device 1 through the mounting portion 125 .

[0060] See also Figure 8 Further, the bracket assembly 2 includes: a first bracket 21, a second bracket 22 and a damping shaft 23. The first bracket 21 and the second bracket 22 are rotatably assembled so that the bracket assembly 2 can be folded and stored. The second bracket 22 is rotatably assembled with the assembly portion 125 through the damping shaft 23.

[0061] It should be noted that the first bracket 21 and the functional device, the first bracket 21 and the second bracket 22, and the second bracket 22 and the clamping device 1 are all connected by a damping shaft 23. Not only can the functional device connected to the folding bracket be rotated and adjusted relative to the first bracket 21 and fixed at the adjusted position; but also the first bracket 21 and the second bracket 22 can be fixed at the adjusted position, so as to facilitate the opening and use of the folding bracket. The folding bracket configured in this way enables the functional device assembled therewith to be adjusted in multiple stages relative to the clamped object, and can be stably fixed at the adjusted position, thereby improving the convenience and stability of the use of the folding bracket.

[0062] See also Figures 8 to 12 In one embodiment, the damping shaft 23 includes: a rotating shaft 231, a first shaft seat 232, a second shaft seat 233, a first shaft body 234, a second shaft body 235 and a second elastic member 236. The rotating shaft 231 passes through the first shaft seat 232, the second shaft seat 233, the first shaft body 234, the second shaft body 235 and the second elastic member 236. The second elastic member 236 is disposed between the first shaft body 234 and the second shaft body 235, and squeezes the first shaft body 234 and the second shaft body 235 to both sides, so that the first shaft seat 232 and the first shaft body 234 and the second shaft seat 233 and the second shaft body 235 generate interaction forces, provide damping force for the damping shaft 23, and realize the damping rotation assembly between the second bracket 22 and the assembly portion 125.

[0063] Specifically, the two ends of the rotating shaft 231 are provided with limiting parts, which are respectively a first limiting part 2311 and a second limiting part 2312. The first shaft seat 232 is sleeved on the rotating shaft 231 and abuts against the first limiting part 2311. The second shaft seat 233 is sleeved on the rotating shaft 231 and abuts against the second limiting part 2312. The first shaft seat 232 and the second shaft seat 233 are both connected to the second bracket 22. The first shaft body 234 is sleeved on the rotating shaft 231 and is located between the first shaft seat 232 and the second shaft seat 233. The first shaft body 234 is connected to the assembly part 125, and one end face thereof abuts against the first shaft seat 232. The second shaft body 235 is sleeved on the rotating shaft 231 and is located between the first shaft body 234 and the second shaft seat 233. The second shaft body 235 is connected to the assembly part 125, and one end face thereof abuts against the second shaft seat 233. The first shaft body 234 and the second shaft body 235 can both rotate around the rotation axis 231 relative to the first shaft seat 232 and the second shaft seat 233. The second elastic member 236 is disposed between the first shaft body 234 and the second shaft body 235.

[0064] See also Fig.11 and Fig.12 In one embodiment, the rotating shaft 231 includes: a shaft core 2313 and an end 2314. Specifically, the shaft core 2313 sequentially passes through the first shaft seat 232, the first shaft body 234, the second elastic member 236, the second shaft body 235 and the second shaft seat 233. The first limiting portion 2311 is connected to an end of the shaft core 2313 away from the end 2314, and the second limiting portion 2312 is connected to an end of the end 2314 away from the first limiting portion 2311. The shaft core 2313 and the end 2314 are threadedly assembled, so that the first shaft seat 232, the first shaft body 234, the second elastic member 236, the second shaft body 235 and the second shaft seat 233 are confined between the first limiting portion 2311 and the second limiting portion 2312.

[0065] It should be noted that, in this embodiment, the second elastic member 236 is a spring. After the damping shaft 23 is assembled, the distance between the first limiting portion 2311 and the second limiting portion 2312 is a fixed value, so that the first shaft seat 232, the first shaft body 234, the second elastic member 236, the second shaft body 235 and the second shaft seat 233 are confined in a fixed area. In other embodiments, the second elastic member 236 can also be a spring block or a spring sheet.

[0066] Specifically, one end of the second elastic member 236 abuts against the first shaft 234, and the other end abuts against the second shaft 235. In the damping shaft 23, the second elastic member 236 is in a compressed state, and the elastic potential energy generated by its compression can squeeze the first shaft 234 toward the first shaft seat 232, and squeeze the second shaft 235 toward the second shaft seat 233, so that the first shaft 234 and the first shaft seat 232 and the second shaft 235 and the second shaft seat 233 generate interaction forces, thereby fixing the second bracket 22 and the clamping device 1 in the rotated position. The damping shaft 23 set in this way can avoid looseness and improve the overall support stability of the folding bracket.

[0067] Please continue reading Figures 8 to 12 It should be noted that, under the action of the second elastic member 336, an interaction force is generated between the first shaft body 234 and the first shaft seat 232 and between the second shaft body 235 and the second shaft seat 233, so that the friction force of rotation between the first shaft body 234 and the first shaft seat 232 and between the second shaft body 235 and the second shaft seat 233 is increased, thereby enabling the second bracket 22 and the clamping device 1 to be fixed in the rotated position.

[0068] It should also be noted that during the production process or the use process, the friction between the first shaft seat 232 and the first shaft body 234 and between the second shaft seat 233 and the second shaft body 235 can be adjusted by replacing the second elastic member 236 with different elastic force or the second elastic member 236 with different length, so as to achieve the purpose of adjusting the rotation tightness of the folding bracket. In this way, the problem of inconvenience in using the folding bracket due to frequent loosening of the damping shaft 23 can be avoided, which is beneficial to the use and maintenance of the folding bracket.

[0069] In one embodiment, a first receiving groove 2341 is formed on one side of the first shaft body 234 close to the second shaft body 235 along the axial direction of the rotating shaft 231. A second receiving groove 2351 is formed on one side of the second shaft body 235 close to the first shaft body 234 along the axial direction of the rotating shaft 231. The second elastic member 236 is sleeved on the rotating shaft 231, and two ends of the second elastic member 236 are respectively received in the first receiving groove 2341 and the second receiving groove 2351.

[0070] Please continue reading Figures 8 to 12In another embodiment, a first damping portion 237 is provided on the end surface of the first shaft body 234 close to the first shaft seat 232 and on the end surface of the second shaft body 235 close to the second shaft seat 233. A second damping portion 238 is provided on the end surface of the first shaft seat 232 close to the first shaft body 234 and on the end surface of the second shaft seat 233 close to the second shaft body 235. The first damping portion 237 and the second damping portion 238 can cooperate with each other to fix the first shaft body 234 and the second shaft body 235 at the rotated position, thereby fixing the clamping device 1 and the second bracket 22 at the rotated position.

[0071] In this embodiment, the first damping part 237 is a first tooth surface; the second damping part 238 is a second tooth surface. When the damping shaft 23 is assembled, the first tooth surface meshes with the second tooth surface. When the clamping device 1 is rotated relative to the second bracket 22, the assembly part 125 drives the first shaft body 234 and the second shaft body 235 to rotate synchronously, so that the first tooth surface and the second tooth surface rotate relative to each other, and when the assembly part 125 stops rotating, the first tooth surface and the second tooth surface can cooperate to limit the assembly part 125 to the position after rotation, thereby limiting the clamping device 1 to the position after rotation.

[0072] It should be noted that a plurality of teeth are provided on both the first tooth surface and the second tooth surface. The meshing of the first tooth surface and the second tooth surface can effectively improve the supporting force of the damping shaft 23 and significantly improve the supporting stability of the folding bracket.

[0073] In one embodiment, the assembly portion 125 is provided with an assembly hole 1251, and the first shaft body 234 and the second shaft body 235 are both installed in the assembly hole 1251. Specifically, a limiting platform 1252 is provided on the inner side wall of the assembly hole 1251. The first shaft body 234 is provided with a first groove 2342, and the second shaft body 235 is provided with a second groove 2352. The first groove 2342 and the second groove 2352 are combined to form a limiting groove, and the limiting groove is adapted to the limiting platform 1252, so that the assembly portion 125 can rotate synchronously with the first shaft body 234 and the second shaft body 235.

[0074] In this embodiment, a plurality of limit platforms 1252 are provided, and the plurality of limit platforms 1252 are evenly distributed in a ring shape on the inner side wall of the assembly hole 1251. Correspondingly, a plurality of limit grooves are also provided, and the plurality of limit grooves are evenly distributed in a ring shape. The plurality of limit platforms 1252 and the plurality of limit grooves are provided to improve the connection stability when the assembly portion 125 rotates with the first shaft body 234 and the second shaft body 235.

[0075] Please continue reading Figures 8 to 12In one embodiment, the second bracket 22 is provided with two connection ends on the side close to the assembly portion 125, which are respectively a first connection end 221 and a second connection end 222. The first connection end 221 is provided with a first mounting opening 2210, and the first shaft seat 232 is limitedly installed in the first mounting opening 2210. The second connection end 222 is provided with a second mounting opening 2220, and the second shaft seat 233 is limitedly installed in the second mounting opening 2220.

[0076] It should be noted that the first tooth surface on the first shaft seat 232 extends out of the first mounting opening 2210 and meshes with the second tooth surface. The first tooth surface on the second shaft seat 233 extends out of the second mounting opening 2220 and meshes with the second tooth surface. In this way, a gap can be provided between the first shaft body 234 and the first connecting end 221 and between the second shaft body 235 and the second connecting end 222, thereby preventing the first shaft body 234, the first connecting end 221, the second shaft body 235 or the second connecting end 222 from being worn.

[0077] In one embodiment, a first positioning groove 2211 is provided on the inner side wall of the first mounting opening 2210, and a first positioning block 2321 is provided on the outer side wall of the first shaft seat 232. The first positioning block 2321 is adapted to the first positioning groove 2211, so that the first shaft seat 232 is limitedly installed in the first mounting opening 2210. Similarly, a second positioning groove 2221 is provided on the inner side wall of the second mounting opening 2220, and a second positioning block 2331 is provided on the outer side wall of the second shaft seat 233. The second positioning block 2331 is adapted to the second positioning groove 2221, so that the second shaft seat 233 is limitedly installed in the second mounting opening 2220. Such an arrangement enables the first shaft seat 232, the second shaft seat 233 and the second bracket 22 to remain relatively fixed when the clamping device 1 rotates, so as to facilitate the rotation of the clamping device 1.

[0078] In this embodiment, four first positioning blocks 2321 are provided, and the four first positioning blocks 2321 are circumferentially evenly spaced on the outer side wall of the first shaft seat 232. Correspondingly, four first positioning grooves 2211 are provided, and the four first positioning grooves 2211 are circumferentially evenly spaced on the inner side wall of the first mounting opening 2210. Similarly, four second positioning blocks 2331 are provided, and the four second positioning blocks 2331 are circumferentially evenly spaced on the outer side wall of the second shaft seat 233. Correspondingly, four second positioning grooves 2221 are provided, and the four second positioning grooves 2221 are circumferentially evenly spaced on the inner side wall of the second mounting opening 2220.

[0079] Please continue Figures 8 to 12 In one embodiment, the assembly portion 125 is further provided with a receiving groove 1253 (see Figure 4), two receiving grooves 1253 are provided, which are respectively located at the two ends of the assembly hole 1251, and the two receiving grooves 1253 are communicated with the assembly hole 1251. Two damping rings 24 are also provided between the assembly part 125 and the first connection end 221 and between the assembly part 125 and the second connection end 222. Specifically, one of the damping rings 24 is tightly fixed in the corresponding receiving groove 1253 by the first connection end 221, and the other damping ring 24 is tightly fixed in the corresponding receiving groove 1253 by the second connection end 222. It should be noted that the provision of the damping ring 24 enables the assembly part 125 and the second bracket 22 to rotate to generate a damping force, further improving the stability of the connection of the folding bracket when supporting.

[0080] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0081] 1) By setting a fastening component to bypass the clamped object and bring the first clamping end and the second clamping end closer to each other, the clamped object located between the first clamping end and the second clamping end is clamped, and the clamped object is confined between the first clamping body and the second clamping body. The clamping device set in this way can not only clamp the clamped object, but also lock the first clamping end and the second clamping end through the fastener, so that the clamping effect of the clamping device is better and the clamping stability is effectively improved.

[0082] 2) The bracket assembly and the clamping device are rotated and assembled through the provided damping shaft, so that after the bracket assembly and the clamping device are relatively rotated, they can be fixed in any position after rotation, which is conducive to the use of the folding bracket; at the same time, a second elastic member is provided between the first shaft body and the second shaft body, and the interaction force between the first shaft body and the first shaft seat and the second shaft body and the second shaft seat is provided through the second elastic member, which can effectively avoid the damping shaft from loosening due to frequent use, thereby improving the damping assembly effect between the clamping device and the bracket assembly.

[0083] 3) The first bracket and the functional device, the first bracket and the second bracket, and the second bracket and the clamping device are all connected by a damping shaft. Not only can the functional device connected to the folding bracket be rotated and adjusted relative to the first bracket and fixed at the adjusted position; but also the first bracket and the second bracket can be fixed at the adjusted position, so as to facilitate the opening and use of the folding bracket. The folding bracket configured in this way enables the functional device assembled therewith to be adjusted in multiple stages relative to the clamped object, and can be stably fixed at the adjusted position, which improves the convenience and stability of the use of the folding bracket.

For those skilled in the art, the present invention may have various modifications and variations.
