At the same time, the limiting member 4 is embedded and installed on the upper and lower sides of the outer surface of the positioning seat 1 3 and the positioning seat 2 5.

[0034] The inner surface of the stationary disc body 1 is threaded with a positioning bolt 6, and a positioning post 17 is installed on the lower surface of the positioning bolt 6. The outer surface of the positioning post 17 is engaged with a limiting member 4. At the same time, the stationary disc body 1 forms an engaging positioning structure with the limiting member 4 through the positioning bolt 6, the positioning post 17 and the positioning member 4.

[0035] Before the static disk body 1 needs to be assembled, a sealing ring 2 will be nested and assembled on the lower surface of the static disk body 1 to ensure the sealing of the static disk body 1 during use. A positioning seat 3 will be installed on the limiting component 4 nested and assembled on the static disk body 1, and a positioning seat 5 will be installed on the other side of the static disk body 1. The positioning bolt 6 of the static disk body 1 will be controlled, thereby controlling the positioning post 17 installed on the positioning bolt 6 to form a positioning engagement with the limiting component 4, thereby improving the stability of the positioning seat 3 and positioning seat 5 assembled on the limiting component 4.

[0036] The rotating shaft 7 is rotatably connected to the inner surface of the positioning seat 3, and a spur gear 8 is mounted on the outer surface of the rotating shaft 7. A toothed gear 9 is meshed with the outer surface of the spur gear 8.

The spur gear 8 and the toothed gear 9 form a meshing structure, and the toothed gear 9 and the toothed gear 11 form a limiting engagement structure through the connecting piece 10.

[0038] The inner surface of the toothed gear 9 is provided with a sliding groove 12, and a sliding shaft 13 is slidably connected to the inner surface of the sliding groove 12. A locking piece 14 is installed on the lower surface of the sliding shaft 13, and the locking piece 14 is limited to slide on the inner surface of the positioning seat 3.
