The lifting rod 6 can support the lifting seat 2, and the first gear 8 and the first rack 7 can control the lifting rod 6 to rise and fall.

[0026] In this embodiment, the lifting assembly also includes a second gear 9 coaxially connected to the first gear 8, a moving rod 10 disposed below the second gear 9, and several sets of second racks 11 disposed on the upper end face of the moving rod 10 and meshing with the second gear 9.

The output shaft of the hydraulic cylinder 26 is provided with a first reinforcing rod connected to the moving rod 10. The hydraulic cylinder 26 controls the second gear 9 to rotate through the second rack 11, thereby controlling the rotation of the first gear 8.

[0027] In this embodiment, the lifting assembly also includes a limiting seat 12 for guiding and limiting the lifting seat 2 and guide slides 13 symmetrically arranged on both sides of the outer surface of the lifting seat 2.
