The surface of the fixing shaft 15 is rotatably connected to a positioning wheel 16. A cam 17 is fixedly connected to one side of the positioning wheel 16. The inner side of the installation tube 12 is provided with a connecting tube 19. The outer surface of the connecting tube 19 is provided with a groove 20. The groove 20 is arc-shaped. The outer side of the groove 20 is symmetrically provided with guide holes 21. The bottom end of the connecting tube 19 is fixedly connected to a fixing plate 23. The bottom end of the fixing plate 23 is fixedly connected to an elastic clip 24.

[0027] Specifically, a neodymium iron boron magnet 9 is fixedly installed in a ring at the bottom of the box cover 2, and a sealing groove 7 is opened in a ring on the top surface of the box body 1. An iron plate 8 is embedded in the inner side of the sealing groove 7, and the iron plate 8 and the neodymium iron boron magnet 9 are magnetically attracted to each other.

[0028] Specifically, a groove 3 is provided in a ring on the outer surface of the box cover 2, a sliding sleeve 4 is provided on the inner side of the groove 3, and a connecting cover 5 is rotatably installed on the outer side of the bottom end of the sliding sleeve 4. Multiple sets of first threaded grooves 10 are evenly provided in a ring on the upper outer surface of the box body 1, and the first threaded grooves 10 are rotatably connected to the inner side of the connecting cover 5 by threads.

[0029] Specifically, the outer surface of the fixed plate 23 is provided with multiple sets of second threaded grooves 25 in a ring shape, the bottom of the fixed plate 23 is provided with a fixed sleeve 26, the inner side of the fixed sleeve 26 is connected to the second threaded grooves 25 by a threaded rotation, and the bottom end of the fixed sleeve 26 is fixedly connected with a limit sleeve 27.

[0030] Specifically, both the limiting sleeve 27 and the elastic retaining strip 24 are cone-shaped, and the elastic retaining strip 24 is evenly arranged in a ring around the bottom of the fixed plate 23.

[0031] Specifically, a rubber ring 6 is fixedly installed in a ring above the bottom inner side of the slide 3, and the surface of the rubber ring 6 is correspondingly set with the bottom surface of the slide sleeve 4.
