The second fixing column 10 can slide into the interior of the slot 8 and fit with the first fixing column 9 to form a cylinder, which is convenient for the insertion of the ring 12. The interior of the slot 8 is movably connected with a plug 11, and one end of the plug 11 is fixedly connected with a ring 12. The ring 12 can be inserted into the outside of the cylinder to prevent the first fixing column 9 and the second fixing column 10 from separating.
