DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] According to Figure 1-Figure 4As shown, it includes a clamping plate 1, a limiting column 11 is installed on one side of the clamping plate 1 near the top, and four groups of limiting grooves 12 are opened on the side surface of the limiting column 11, a top plate 13 is installed on one side of the clamping plate 1 near the limit column 11, and a slide groove 14 is opened inside the top plate 13, an electric push rod 15 is installed on the top of the top plate 13 near one side, and a moving plate 16 is installed at one end of the electric push rod 15, limiting plates 17 are installed on both sides of the moving plate 16 near the top, and the bottom surfaces of the two groups of limiting plates 17 are both arranged to fit the top surface of the top plate 13, and one end of the moving plate 16 passes through the interior of the top plate 13 through the slide groove 14 and is slidably connected to the interior of the slide groove 14.

[0020] A clamping ring 2 is installed at the bottom end of the movable plate 16, and four groups of limit blocks 21 are installed on the inner wall of the clamping ring 2. The limit blocks 21 are located inside the limit groove 12 and are slidably connected to the inside of the limit groove 12. A clamping rod 22 is installed at the bottom end of the limit block 21, and a mounting groove 23 is opened inside the clamping rod 22 near the bottom, and a through groove 24 is opened on one side of the clamping rod 22 near the bottom. A support spring 25 is installed on the top inner wall of the mounting groove 23, and an iron rod 26 is installed at the bottom end of the support spring 25. A toggle plate 27 is installed on the side surface of the iron rod 26, and one end of the toggle plate 27 passes through the through groove 24 and penetrates through the inner wall of one side of the mounting groove 23.

[0021] A base plate 3 is installed on one side of the clamping plate 1 near the bottom end, and a telescopic spring 31 is installed on the top of the base plate 3, an arc plate 32 is installed on the top of the telescopic spring 31, and a mounting plate 33 is installed on one side of the arc plate 32, a magnet disk 34 is installed on the top of the mounting plate 33, and a magnet disk 34 is arranged directly below the iron rod 26.

[0022] When in use, the user can sleeve the brake arm on the outer surface of the limit column 11. At the same time, the arc plate 32 can be adjusted up and down accordingly according to the length of the brake arm, so that the inner wall of the arc plate 32 can be fitted with the bottom end of the brake arm. At this time, the telescopic spring 31 can be compressed accordingly. At this time, under the action of the elastic restoring force of the telescopic spring 31, the inner wall of the arc plate 32 can be tightly fitted with the bottom end of the brake arm, and the setting of the arc plate 32 can support the brake arm, so that the brake arm can be stably sleeved on the outer surface of the limit column 11. After that, the user can start the electric push rod 15, so that under the operation of the electric push rod 15, the movable plate 16 can move in the direction of the brake arm inside the slide groove 14, so that the two sets of limit plates 17 can move accordingly, so that the clamping ring 2, the limit block 21 and the clamping rod 22 can move accordingly. The corresponding movement enables the four groups of limit blocks 21 to slide correspondingly in the corresponding limit grooves 12 respectively, so that the inner surfaces of the clamping ring 2 and the clamping rod 22 can finally fit tightly with the side surface of the brake arm. At this time, the electric push rod 15 can be closed, so that the brake arm can be limited, clamped and fixed under the joint action of the clamping plate 1, the clamping ring 2 and the clamping rod 22. Finally, the user can move downward through the through groove 24 through the toggle plate 27, so that the iron rod 26 can move downward accordingly. At the same time, the support spring 25 will expand and contract downward accordingly, so that the support spring 25 can always support the iron rod 26. When the iron rod 26 moves downward until its bottom end fits with the top of the magnet disk 34 and is adsorbed and fixed, the downward movement of the iron rod 26 can be stopped. At this time, the clamping ring 2 and the clamping rod 22 can be fixed, so as to further improve the clamping stability of the brake arm.
