[0027] In the embodiment, the position of the support 2 mounted on the surface of the rotating shaft 42 and the U-shaped frame 43 can be locked in the locked state through the catch pin 45.

[0028] Specifically, the number of the push blocks 46 is two, and the two push blocks 46 are arranged in a circumferential array about the catch pin 45, so that the push blocks 46 can be held by an operator to facilitate adjustment of the state of the catch pin 45.

[0029] In the embodiment, the clamping assembly 5 comprises a positioning frame 51, the positioning frame 51 is fixedly connected with the arc surface of the support 2, one end of the positioning frame 51 away from the support 2 is fixedly connected with a limiting plate 52, a circular hole is formed in the surface of the limiting plate 52, the limiting plate 52 is rotatably connected with an adjusting screw 53 on the inner wall of the circular hole, the adjusting screw 53 is fixedly connected with an anti-skid knob 54 at an end away from the support 2, a linkage frame 55 is in sliding connection with the surface of the positioning frame 51, a threaded sleeve 56 is fixedly connected with the linkage frame 55 on the side close to the rubber barrier 1, the threaded sleeve 56 is in threaded connection with the surface of the adjusting screw 53, a clamping plate 57 is fixedly connected with the lower surface of the linkage frame 55, and a conical protrusion 58 is fixedly connected with the clamping plate 57 on the side close to the rubber barrier 1.

[0030] In the embodiment, the position of the linkage frame 55 can be locked through cooperation of the adjusting screw 53 and the threaded sleeve 56, and the stability of the linkage frame 55 in the locked state can be ensured.

[0035] When the rubber barrier 1 is sleeved, the rubber barrier 1 is ensured to be in the clamping area formed by the clamping plate 57 and the bracket 2, and then the rubber barrier 1 is limited on the bracket 2 under the action of its own tension to complete the unfolding. After the rubber barrier 1 is unfolded, the anti-skid knob 54 is rotated to adjust the screw rod 53, the screw rod 53 is engaged with the threaded sleeve 56, the threaded sleeve 56 pulls the linkage frame 55 under the action of the screw rod 53, the linkage frame 55 pulls the clamping plate 57 under the guidance of the positioning frame 51, and the clamping plate 57 pushes the conical block 58 close to the rubber barrier 1. When the clamping plate 57 moves to the maximum distance, the clamping plate 57 can cooperate with the conical block 58 and the bracket 2 to clamp the rubber barrier 1, so as to improve the stability of the rubber barrier 1 in the unfolded state. By setting the clamping assembly 5, the stability of the moisture-proof device in use is improved, thereby reducing the problem that the moisture-proof device is only fixed by its own tension, which is prone to looseness during use, and further improving the firmness of the moisture-proof device in the unfolded state.
