The top surface of the piston rod 1031 is fixedly connected to the bottom surface of the bearing plate 105.

[0030] In this embodiment, the electric push rod 104 is mainly used to drive the supporting plate 105 to move vertically, and the sliding fit between the piston rod 1031 and the piston cylinder 103 can support the supporting plate 105, ensuring the stability of the supporting plate 105 during movement, so that the bottom of the cylinder 108 gradually passes through the No. 1 circular groove 102 and contacts the ground, thereby realizing the position adjustment of the cylinder 108.
