Specifically, the first driving member 40 is a hydraulic cylinder, and it is understood that in other embodiments, the first driving member 40 may be replaced by other structures with equivalent functions or functions. The first driving member 40 includes a first hydraulic cylinder 41 and a first piston rod 42, one end of the first piston rod 42 is connected to the first hydraulic cylinder 41, and the other end is connected to the fixing frame 10. The first hydraulic cylinder 41 drives the first piston rod 42 to extend and contract, thereby driving the fixing frame 10 to move. The first hydraulic cylinder 41 contains liquid, and the first piston rod 42 is moved by the change of the volume of the liquid, so that the hydraulic cylinder is commonly used in the prior art, and the description thereof is omitted here.
