The other end of the first spring 604 is hooked on the fixed rod 605 through a hook. A plug-in rod 606 is slidingly connected in a circular hole of the fixed box body 1. A handle 607 is welded on one end of the plug-in rod 606, and a rectangular block 608 is welded on the other end of the plug-in rod 606. A sealing ring is attached to the outer wall of the plug-in rod 606. The size of the rectangular block 608 is matched with the size of the rectangular groove 602.

[0033] A second spring 609 is sleeved on the outer wall of the plug-in rod 606. The two ends of the second spring 609 are respectively welded on the outer walls of the fixed box body 1 and the handle 607. A first positioning block 610 and a second positioning block 611 are welded on the outer wall of the circular hole of the fixed box body 1.
