The support rod 12 has a sliding connection to the insert rod 16. The insert rod 16 has a threaded connection to the double-acting screw A17. The top surface of the slide rod A14 is fixedly installed with a handrail 18. The crossbar 13 has a sliding connection to the slide rod B20. The crossbar 13 has a spring A19 inside. One end of the crossbar 13 is fixedly installed with a connecting plate 21. The lifting plate C8 is rotatably connected to the output end of the hydraulic cylinder 7. The lifting plate A4 is fixedly connected to the base plate 3. The lifting plate A4 is rotatably connected to the lifting plate C8. The lifting plate B6 is rotatably connected to the lifting plate D9. The lifting plate C8 is rollingly connected to the top plate 10. One end of the spring A19 is connected to the surface of the slide rod B20, and the other end is connected to the inner surface of the crossbar 13. The connecting plate 21 is slidably connected to the worktable 11. The insert rod 16 is slidably connected to the positioning hole 15.

[0026] In this embodiment: the hydraulic cylinder 7 drives the lifting plate C8 to rotate. When the lifting plate C8 rotates, it drives the lifting plate A4 to rotate, thereby causing the lifting plate A4 to slide inside the base plate 3. When the lifting plate C8 rotates, it drives the top plate 10 to move upward. At the same time, the lifting plate C8 also slides inside the top plate 10.
