[0021] By adopting the above technical solution, when the screw 10 rotates, the screw 10 and the threaded cylinder 3 cooperate with each other, and under the action of the convex plate 4, the threaded cylinder 3 can move up and down.

[0022] A ring 12 is fixedly connected to the top surface of the protrusion 11, and a crossbar 13 is inserted through the ring opening of the ring 12.
