[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] Firstly, the support structure of this utility model embodiment is as follows: Figures 1 to 4 As shown, the system includes a first frame 1 and a second frame 2 rotatably connected by a rotating connection structure. The first frame 1 has a damping surface 11 arranged around the central axis of the rotating connection structure. A damping pad 21 is fixed to the second frame 2 at a position corresponding to the damping surface 11. The damping pad 21 is preferably made of silicone or rubber. The damping pad 21 is in close contact with the damping surface 11 to restrict the relative rotation of the first frame 1 and the second frame 2. In this embodiment, due to the close contact between the damping pad 21 and the damping surface 11, a large resistance is felt during the adjustment of the bracket angle. When the angle is adjusted to the desired position, the stable and strong friction between the damping pad 21 and the damping surface 11 effectively restricts the relative rotation between the first frame 1 and the second frame 2, thus maintaining stability after the bracket is adjusted to the required angle, ensuring the angle limiting effect of the bracket. This structure is simple in design, easy to assemble, has a relatively low manufacturing cost, and can meet the angle fixing requirements of the bracket in practical applications.

[0025] Preferably, the damping surface 11 can be an arc surface or a circumferential surface, with the central axis of the arc surface or circumferential surface coinciding with the central axis of the rotating connection structure. When adjusting the bracket angle, the contact surface between the damping surface 11 and the damping pad 21 can maintain stable sliding friction, avoiding jamming caused by uneven surfaces or design defects, thus ensuring the uniformity and stability of friction force throughout the entire rotation range. The arc surface adopts a partial ring design, which is suitable for a smaller angle adjustment range; while the circumferential surface is a complete ring design, suitable for large angle adjustment.

[0026] refer to Figures 1 to 4The first frame body 1 is provided with an axial shaft body 10 along the rotating connection structure, the two ends of the shaft body 10 are provided with connecting shafts 101 protruding outward along the axial direction, and the damping surface 11 is arranged on the side circumferential surface of the shaft body 10. The second frame body 2 is provided with two opposite connecting plates 20, the connecting plates 20 are provided with connecting holes 201 corresponding to the connecting shafts 101, the connecting shafts 101 and the connecting holes 201 are inserted and matched to form the rotating connection structure, so that the relative rotation between the first frame body 1 and the second frame body 2 is realized.

[0027] Referring to Figure 3 and Figure 4 , the second frame body 2 is provided with the damping rubber pads 21 at the two ends close to the connecting plates 20, and the shaft body 10 is provided with the damping surfaces 11 corresponding to the damping rubber pads 21. By arranging the damping rubber pads 21 close to the two connecting plates 20 and the damping surfaces 11 matched with the damping rubber pads 21, uniform distributed damping force can be provided, so that the stability and balance of the force between the first frame body 1 and the second frame body 2 are improved.

[0028] Continuing to refer to Figure 3 and Figure 4 , in order to prevent the connecting shaft 101 from exiting from the connecting hole 201, the connecting shaft 101 is fixed with a limiting screw 3 at the end, the limiting screw 3 is provided with a stop pad 30, the stop pad 3 forms a stop position from the outside to the connecting plate 20, so that the connecting shaft 101 and the connecting hole are kept inserted, the stability of the structure is enhanced, and the accidental disengagement of the connecting shaft 101 from the connecting hole 201 is avoided to cause connection failure.

[0029] Preferably, the damping rubber pad 21 is adhesively fixed on the second frame body 2, the adhesive bonding makes the damping rubber pad 21 closely combined with the second frame body 2, effectively preventing the damping rubber pad from loosening or falling off during use.

[0030] Further, referring to Figure 2 , in order to enhance the limiting effect on the damping rubber pad 21, the second frame body 2 is provided with a limiting groove 22, and the damping rubber pad 21 is fixed in the limiting groove 22. The limiting of the damping rubber pad 21 by the limiting groove 22 can effectively prevent the damping rubber pad 21 from shifting or falling off during use. Preferably, the limiting groove 22 is a strip-shaped groove arranged along the axial direction of the rotating connection structure, so that a plurality of damping rubber pads 21 can be arranged at intervals along the length direction of the strip-shaped groove, or the damping rubber pad 21 is fixed in the entire limiting groove 22 to ensure the damping limiting effect.
