The two ends of the lifting rod 33 are respectively connected to the two sets of cross arms, and the middle positions of the two cross arms in the same set along the length direction are rotatably connected to the lifting rod 33 to realize the rotatable connection of the two cross arms together.

[0032] Specifically, the scissor lifting mechanism 3 also includes a hydraulic cylinder 34, the cylinder body of which is rotatably connected to the top of the movable seat 1, and the piston rod is rotatably connected to the lifting rod 33.

[0033] Specifically, the scissor lifting mechanism 3 also includes a guide rail 35, with each roller 36 corresponding to a guide rail 35. The guide rail 35 is provided with a guide groove 351, and the roller 36 rolls in the guide groove 351. The guide rail 35 located at the top of the cross arm is fixedly connected to the lifting plate 21, and the guide rail 35 located at the bottom of the cross arm is fixedly connected to the movable seat 1.

[0034] Specifically, a fixing ring 241 is provided on the outer side of the bottom of the limiting rod 24, and a spring 242 is provided on the outer sleeve of the limiting rod 24, located between the fixing ring 241 and the support plate 22.
