The top end of the first hydraulic cylinder 3 is hinged to the top of the frame 1, and the bottom end of the first hydraulic cylinder 3 is hinged to the lifting frame 2. The first hydraulic cylinder 3 is used to drive the lifting frame 2 to move up and down along the guide rail 11.

[0017] like Figure 4 As shown, a first limiting component 4 is provided in the middle of the frame 1. The first limiting component 4 includes a fixed frame 41, a first guide rod 42, a support block 43, and a second hydraulic cylinder 44. The fixed frame 41 is provided on the frame 1, the first guide rod 42 is slidably provided on the fixed frame 41, the support block 43 is provided at one end of the first guide rod 42 near the lifting frame 2, and the second hydraulic cylinder 44 is provided on the fixed frame 41.

The piston rod of the second hydraulic cylinder 44 is connected to the connecting plate 45. The second hydraulic cylinder 44 can push the connecting plate 45 to translate, so as to drive the support block 43 to move horizontally, so that the support block 43 moves closer to or away from the lifting frame 2.

[0020] Preferably, the bottom of the lifting frame 2 is provided with a buffer pad 23.

[0021] like Figure 2 As shown, preferably, a second limiting component 5 is provided at the bottom of the frame 1.
