Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a clamping device and a folding bracket. Background Art

[0002] With the development of science and technology, more and more functional devices (such as fill lights, electric fans, etc.) are appearing in our lives. These devices require brackets for support and fixation when in use. For the convenience of use, existing brackets usually have a clip at the bottom of the bracket, and the bracket is clamped on different objects through the clip to improve the diversity of bracket use. However, the existing clip only clamps external objects through the upper and lower clamping plates, which is very likely to cause the clamping to become loose, thereby causing the bracket and the functional device to fall, which is not conducive to the use of the bracket.

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

[0035] See also Figures 1 to 3 In one embodiment, the folding stand includes a clamping device 1 and a stand assembly 2. The clamping device 1 is connected to the stand assembly 2. Apparently, the clamping device 1 provided on the stand assembly 2 not only enables the stand assembly 2 to be clamped with other objects through the clamping device 1, thereby facilitating the assembly of functional devices such as a fan head or a fill light, but also serves as a base, allowing the functional devices assembled on the stand assembly 2 to be placed on a desktop or tabletop for use, thereby increasing the diversity of the stand assembly 2's usage scenarios.

[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 provided on the first clamping body 11, and another portion is provided 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. Fixing the first clamping end 111 and the second clamping end 121 by the fastening assembly 13 can, on the one hand, improve the stability of the clamping between the first clamping end 111 and the second clamping end 121, making the first clamping end 111 and the second clamping end 121 clamped more firmly; on the other hand, it can prevent the clamped object from detaching 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 near the second clamping body 12, and on the end surface of the second clamping body 12 near the first clamping body 11. The clamping groove 100 is provided near the fastening assembly 13. When the clamping device 1 clamps another object, the clamped object is located between the first clamping body 11 and the second clamping body 12 and is confined within the clamping groove 100, making the clamping device 1 more stable and facilitating the use of the foldable bracket.

[0039] In one embodiment, the clamping grooves 100 are provided in two groups, namely the first clamping groove 1001 and the 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. Providing the first clamping slot 1001 and the second clamping slot 1002 with different slot sizes enables the clamping device to be suitable for clamping rod-shaped objects of different sizes.

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

[0041] It should be noted that the slot dimension D1 of the first clamping groove 1001 is smaller than the slot dimension D2 of the second clamping groove 1002, and the first clamping groove 1001 has an arc-shaped cross-section, which makes the first clamping groove 1001 more secure for rod-shaped objects with circular cross-sections. The depth of the second clamping groove 1002 (the distance from the slot to the lowest point of the groove bottom) is greater than the depth of the first clamping groove 1001, and the second clamping groove 1002 has an elliptical cross-section, which makes the second clamping groove 1002 more secure for rod-shaped objects with oblate cross-sections.

[0042] It should also be noted that the folding bracket of this embodiment is primarily used for a stroller fan (i.e., the functional device is a stroller fan head), allowing the stroller fan to be clamped onto the stroller's rod for use. Since stroller rods are primarily cylindrical, oblate cylindrical, or elliptical, cylindrical rods are suitable for position limiting by the first clamping groove 1001 on the clamping device 1, making the folding bracket more stable during use; whereas oblate cylindrical or elliptical rods are suitable for position limiting by the second clamping groove 1002 on the clamping device 1, thereby improving the stability of the folding bracket during use. In this way, a folding bracket provided with a clamping device 1 having both the first clamping groove 1001 and the second clamping groove 1002 is more convenient for use with a 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 the clamping of the clamping device 1 and the clamped object, ensuring 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 stand is placed on a table or countertop, the support pad 112 can increase the friction between the folding stand and the table or countertop, thereby improving the support stability of the folding stand.

[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 causes 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 to move away from each other, thereby bringing the first clamping end 111 and the second clamping end 121 closer to each other to clamp the clamped object. The rotating member 16 passes through 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 rotatably assembled.

[0046] Please continue reading Figures 4 to 7 In one embodiment, an L-shaped limiting 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 limiting 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 limiting gap is formed between the two parallel clamping strips 122, and the other end of the first elastic member 15 is confined within the limiting 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 end portions of the first elastic member 15 on the side close to the second clamping body 12.

[0047] In one embodiment, a first mounting ear 114 is provided on the side of the first clamping body 11 proximate to the second clamping body 12, and a second mounting ear 123 is provided on the side of the second clamping body 12 proximate to the first clamping body 11. Both the first mounting ear 114 and the second mounting ear 123 are provided with a through-hole 101. A rotating shaft 161 is provided on the end surface of one side of the rotating member 16. The rotating shaft 161 extends through and engages within the through-hole 101, allowing the first clamping body 11 and the second clamping body 12 to be rotatably assembled.

[0048] Please return Figures 2 to 4 In one embodiment, the fastening assembly 13 includes a buckle 131 and a strap 132. The 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 buckle 131, so that the first clamping end 111 and the second clamping end 121 cooperate to clamp the object, and lock the first clamping end 111 and the second clamping end 121 in the clamped state.

[0049] In one embodiment, the lock 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 away from the first clamping end 111. The curved extension section 1312 is connected to the end of the fixed section 1311 away from the first clamping end 111. The curved extension section 1312 extends 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 smoothly transition, allowing the first clamping end 111 to clamp an object. One end of the curved extension section 1312 is connected to the fixed section 1311 via a chamfered 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. With this arrangement, the angle formed between the fixed section 1311 and the curved extension section 1312 is an obtuse angle, making the connection between the buckle 131 and the strap 132 more secure. 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 buckle 131 is able to cooperate with and lock the strap 132.

[0051] In one embodiment, the strap 132 is a flexible strap that can be bent and snapped into engagement with the buckle 131. The strap 132 is provided with multiple buttonholes 1321 extending through the strap 132. The multiple buttonholes 1321 are evenly spaced along the length of the strap 132. In this embodiment, there are seven buttonholes 1321, all of which are waist-shaped.

[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 the 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 at the same time improve the overall aesthetics of the clamping device 1.

[0053] In one embodiment, a limiting post 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 stored, the limiting post 1322 cooperates with the limiting hole 1241 to firmly confine the strap 132 within the receiving slot 124, preventing the strap 132 from escaping.

[0054] In this embodiment, the limiting post 1322 is made of a flexible material, and an annular protrusion 13221 is provided on the outer side wall of the limiting post 1322. Specifically, the end of the limiting post 1322 away from the bandage 132 is configured to be spherical so that the limiting post 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 post 1322 is engaged with the limiting hole 1241, a force is applied to the bandage 132, causing the annular protrusion 13221 to pass through the limiting hole 1241. When the annular protrusion 13221 passes through the limiting hole 1241, it is elastically deformed by the pressure of the limiting hole 1241, and returns to its original shape after the annular protrusion 13221 passes through the limiting hole 1241. In this way, the limiting column 1322 can be confined in the limiting hole 1241 through the cooperation between the annular protrusion 13221 and the limiting hole 1241, thereby preventing the strap 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 near the second clamping end 121, and the two ends of the hinge shaft 132 are respectively connected to the two side walls extending along the length of the receiving slot 124, thereby rotatably assembling 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 to provide the hinged end of the strap 132 with sufficient movable space, thereby facilitating the strap 132 to rotate relative to the second clamping body 12 .

[0057] In one embodiment, the avoidance groove 1242 passes through the second clamping body 12 , and an n-shaped notch 12421 is provided on the sidewall 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 provided on the end surface of the clamping rubber pad 14 installed on the second clamping body 12, which is away from the first clamping body 11. Two abutment platforms 141 are provided. The clamping rubber pad 14 is fixed to the second clamping body 12 by gluing. When the clamping rubber pad 14 is bonded 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 within the n-shaped notches 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 Furthermore, 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 via the damping shaft 23.

[0061] It should be noted that a damping shaft 23 is used to connect 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. This not only allows the functional device connected to the folding bracket to be rotated and adjusted relative to the first bracket 21 and fixed in the adjusted position; it also allows the first bracket 21 and the second bracket 22 to be fixed in the adjusted position, thereby facilitating the opening and use of the folding bracket. This configuration of the folding bracket allows the functional device attached to it to be adjusted in multiple levels relative to the clamped object and to be stably fixed in the adjusted position, improving the convenience and stability 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 toward each other, generating interaction forces 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, thereby providing damping force for the damping shaft 23 and achieving damped rotational assembly between the second bracket 22 and the assembly portion 125.

[0063] Specifically, limiting portions are provided at both ends of the rotating shaft 231, namely a first limiting portion 2311 and a second limiting portion 2312. The first shaft seat 232 is sleeved on the rotating shaft 231 and abuts the first limiting portion 2311. The second shaft seat 233 is sleeved on the rotating shaft 231 and abuts the second limiting portion 2312. Both the first shaft seat 232 and the second shaft seat 233 are connected to the second bracket 22. The first shaft body 234 is sleeved on the rotating shaft 231 and located between the first shaft seat 232 and the second shaft seat 233. The first shaft body 234 is connected to the assembly portion 125, and one end face of the first shaft body 234 abuts the first shaft seat 232. The second shaft body 235 is sleeved on the rotating shaft 231 and located between the first shaft body 234 and the second shaft seat 233. The second shaft body 235 is connected to the assembly portion 125, and one end face of the second shaft body 235 abuts the second shaft seat 233. The first shaft body 234 and the second shaft body 235 are both rotatable 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 Figure 11 and Figure 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 a first shaft seat 232, a first shaft body 234, a second elastic member 236, a second shaft body 235, and a 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, thereby confining 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 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 constant, thereby confining 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 within a fixed area. In other embodiments, the second elastic member 236 may also be a spring block or a spring clip.

[0066] Specifically, one end of the second elastic member 236 abuts the first shaft 234, and the other end abuts the second shaft 235. Furthermore, in the damping shaft 23, the second elastic member 236 is in a compressed state. The elastic potential energy generated by this compression can squeeze the first shaft 234 toward the first shaft seat 232 and the second shaft 235 toward the second shaft seat 233. This creates interaction forces between the first shaft 234 and the first shaft seat 232, and between the second shaft 235 and the second shaft seat 233, thereby securing the second bracket 22 and the clamping device 1 in their rotated positions. This configuration of the damping shaft 23 prevents loosening and improves 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 increases, 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 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 elasticity 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 defined on the first shaft 234 near the second shaft 235, along the axis of the rotating shaft 231. A second receiving groove 2351 is defined on the second shaft 235 near the first shaft 234, along the axis of the rotating shaft 231. The second elastic member 236 is sleeved on the rotating shaft 231, with its ends 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 near the first shaft seat 232 and on the end surface of the second shaft body 235 near the second shaft seat 233. A second damping portion 238 is provided on the end surface of the first shaft seat 232 near the first shaft body 234 and on the end surface of the second shaft seat 233 near the second shaft body 235. The first damping portion 237 and the second damping portion 238 cooperate with each other to fix the first shaft body 234 and the second shaft body 235 in their rotated positions, thereby fixing the clamping device 1 and the second bracket 22 in their rotated positions.

[0071] In this embodiment, the first damping portion 237 is a first tooth surface, and the second damping portion 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 portion 125 drives the first shaft 234 and the second shaft 235 to rotate synchronously, causing the first tooth surface and the second tooth surface to rotate relative to each other. When the assembly portion 125 stops rotating, the first tooth surface and the second tooth surface cooperate to confine the assembly portion 125 in its rotated position, thereby confining the clamping device 1 in its rotated position.

[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, into which the first shaft 234 and the second shaft 235 are both mounted. Specifically, a limiting platform 1252 is provided on the inner sidewall of the assembly hole 1251. The first shaft 234 is provided with a first groove 2342, and the second shaft 235 is provided with a second groove 2352. The first groove 2342 and the second groove 2352 combine to form a limiting groove, which is adapted to the limiting platform 1252, enabling the assembly portion 125 to rotate synchronously with the first shaft 234 and the second shaft 235.

[0074] In this embodiment, multiple limiting platforms 1252 are provided, and the multiple limiting platforms 1252 are evenly spaced annularly on the inner sidewall of the assembly hole 1251. Correspondingly, multiple limiting grooves are also provided, and the multiple limiting grooves are evenly spaced annularly. The multiple limiting platforms 1252 and the multiple limiting grooves can improve the connection stability between the assembly portion 125 and the first and second shafts 234, 235 during rotation.

[0075] Please continue reading Figures 8 to 12In one embodiment, the second bracket 22 has two connecting ends near the assembly portion 125, namely a first connecting end 221 and a second connecting end 222. The first connecting end 221 has a first mounting opening 2210, and the first shaft seat 232 is positioned and installed in the first mounting opening 2210. The second connecting end 222 has a second mounting opening 2220, and the second shaft seat 233 is positioned and 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. This arrangement creates a gap 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 wear on the first shaft body 234, the first connecting end 221, the second shaft body 235, or the second connecting end 222.

[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 fixedly 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 fixedly installed in the second mounting opening 2220. This configuration 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, thereby facilitating 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 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 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 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 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, respectively located at the two ends of the assembly hole 1251, and both receiving grooves 1253 are in communication with the assembly hole 1251. Two damping rings 24 are further provided between the assembly portion 125 and the first connection end 221 and between the assembly portion 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 portion 125 and the second bracket 22 to rotate to generate a damping force, further improving the stability of the connection of the folding bracket during support.

[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 close 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 at 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) Damping shafts are used to connect the first bracket to the functional device, the first bracket to the second bracket, and the second bracket to the clamping device. This not only allows the functional device connected to the folding bracket to be rotated and adjusted relative to the first bracket and fixed in the adjusted position, but also allows the first bracket and the second bracket to be fixed in the adjusted position, thereby facilitating the opening and use of the folding bracket. This configuration of the folding bracket allows the functional device attached to it to be adjusted in multiple levels relative to the clamped object and to be stably fixed in the adjusted position, improving the convenience and stability of the folding bracket.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
