[0009] Furthermore, the output end of the cylinder faces the ground, and a rubber pad is installed on the output end of the cylinder.

[0010] Furthermore, one end of the hollow block is fixedly connected to a connecting pipe, and two arc-shaped plates are provided and are respectively fixedly connected to two side walls of the hollow block.
