[0032] Others, such as Figure 6 As shown in , a rotating motor 604 is installed on the main seat 602, a turntable plate 600 is rotatably installed on the top of the main seat 602 through a turntable bearing 603, and a housing 700 is installed at the bottom of the main seat 602, which is sleeved on the outside of the rotating motor 604 and communicated with the hollow shaft 605. Among them, the housing 700 can play a waterproof role, and the hollow shaft 605 is convenient for inserting the connecting wire therethrough.

[0033] In implementation, the bearing seat 204 of the ball bearing 205 is fixedly installed in the installation groove a203, the mouth of the installation groove a203 is fixedly installed with a cover plate 201, and a curved pipe 202 is installed on one side of the cover plate 201. When in use, the bearing seat 204 is fixed in the installation groove a203 by bolts, and after the cover plate 201 is removed, the bearing seat 204 is conveniently removed as a whole.

[0034] When implementing, Figure 4 As shown in FIG. 6 , one end of the curved pipe 202 can communicate with the interior of the housing 700 through the hollow shaft 605, and the other end of the curved pipe 202 is vertically arranged downward. The curved pipe 202 is arranged downward, which can achieve a good waterproof effect.

[0035] Specifically, a servo motor 400 for driving the harmonic reducer 302 is fixedly mounted on the other side of the support base B300.

[0036] Example 2

[0037] Different from the first embodiment, a positioning post 606 is fixedly connected to the center of one side of the disk 601, and a positioning hole 305 is provided in the center of the connecting disk 304 to fit the positioning post 606.
