One end of the worm 4 is rotatably connected to one side of the inner wall of the inner cavity through a bearing. By utilizing the self-locking property of the worm 4 and the worm wheel 5, the fixation is more stable. The other end of the worm 4 passes through the box body 1 and is fixedly installed with a rotating block 6. A positioning hole 7 is also provided on the box body 1, and secondary fixation can be performed through the positioning hole 7.

[0026] Specifically, by rotating the rotating block 6, the worm 4 is driven to rotate, thereby driving the worm wheel 5 meshingly connected to the outer wall of the worm 4 to rotate, and then driving the screw 211 fixedly mounted on the inner wall of the worm wheel 5 to rotate, so that the screw lifting plate 212 threadedly mounted on the outer wall of the screw 211 moves upward, so that the piston 214 can be driven by the connecting rod 215 to move upward on the inner wall of the piston chamber 213, so that the inner wall of the piston chamber 213 is negative pressure, so that the suction cup 216 can be sucked at the specified position, thereby achieving the purpose of facilitating the fixing of the box body 1. By utilizing the self-locking property of the worm 4 and the worm wheel 5, the fixation is more stable, making it convenient to fix on a wall or the like, and it can also be fixed for a second time through the positioning hole 7.

[0027] like Figure 1-4As shown, the sealing mechanism 31 includes a sealing cover 311, which is arranged on the top of the box body 1, and a sealing ring 312 is fixedly installed on the bottom of the sealing cover 311.
