The electric telescopic rod 401 is fixedly installed on the front side of the rectangular block 1. The mounting plate 402 is fixedly installed on the left side of the piston rod of the electric telescopic rod 401. The right side of the mounting plate 402 is fixedly connected to the left side of the movable plate 3.

[0022] In this embodiment, the piston rod of the electric telescopic rod 401 drives the mounting plate 402 to move left and right, so that the mounting plate 402 drives the movable plate 3 to move left and right, and the movable plate 3 drives the first limiting mechanism 6 to move left and right.
