A square groove 121 is formed on the inner hole of the upper end of the installation seat 12, a plurality of square grooves 121 are correspondingly arranged with the square teeth 261, and the square teeth 261 are clamped in the square grooves 121. When the main shaft 26 rotates around its own axis direction, the installation seat 12 is driven to rotate around its own axis direction through the clamped square teeth 261 and the square grooves 121.

[0036] The output shaft of the driving motor 13 rotates to drive the small helical gears 21 to rotate, the small helical gears 21 drive the large helical gears 22 to rotate, the large helical gears 22 drive the rotating shaft 23 to rotate around its own axis direction, the rotating shaft 23 drives the small spiral bevel gear 25 to rotate, the small spiral bevel gear 25 drives the large spiral bevel gear 24 to rotate, the large spiral bevel gear 24 drives the main shaft 26 to rotate, and the main shaft 26 drives the installation seat 12 to rotate around its own axis direction through the square tooth 261.

[0037] Referring to Figures 2-4A lifting seat 3 is fitted onto the outer side of the mounting base 12. The lifting seat 3 is coaxially arranged with the mounting base 12. The mounting base 12 is fixed inside the lifting seat 3 by bearings. A transmission shaft 4 is arranged on the radial side of the mounting base 12 near the drive motor 13. The transmission shaft 4 is horizontally arranged, and its axis is perpendicular to the output shaft axis of the drive motor 13. A transmission gear 45 is coaxially fixed on the transmission shaft 4. A transmission rack 31 is formed on the side of the mounting base 12 near the transmission gear 45. Multiple teeth of the transmission rack 31 are arranged vertically, and the transmission gear 45 and the transmission rack 31 mesh with each other.

[0038] A large reduction gear 6 is mounted on the drive shaft 4. A reduction shaft 83 is located on the side of the drive shaft 4 away from the lifting seat 3.
