[0031] The working principle of this utility model:

[0032] When the utility model is in use, first, by rotating the handle 302, the handle 302 drives the disk 303 to rotate, and then the disk 303 drives the rotating rod 304 to rotate. Since the point position of the disk 303 changes when the disk 303 rotates, the disk 303 causes the rotating rod 304 to move when the rotating rod 304 rotates, and then the rotating rod 304 drives the moving rod 306 to move, and then the moving rod 306 drives the sleeve 309 to move, so that the sleeve 309 covers one side of the device body 1, and at the same time, the disk 303 also drives the fixed rod 311 to rotate , and then the fixed rod 311 will drive the sleeve block 312 to rotate.
