The output end of the reducer 17 is bolted to the rotating arm 4.

[0024] Since motor 2 8 is mounted on support plate 6 via positioning seat 16, and the output shaft of motor 2 8 is connected to rotating arm 4 via reducer 2, the rotation between support plate 6 and rotating arm 4 can be achieved by rotating motor 2 8.

A sliding groove adapted to the protrusion is opened on the side of the vertical shaft 9.

[0027] Motor 318 drives synchronous pulley 21 to rotate through reducer 319. The rotation of vertical shaft 9 can be achieved through the cooperation of the inner protrusion of synchronous pulley 21 and the sliding groove on the side of vertical shaft 9.

A limiting sleeve 28 is fixedly connected to the upper side of the support frame 23 and sleeved on the outside of the vertical shaft 9.

[0029] Motor 4 24 drives synchronous belt 27 to rotate, and synchronous belt 27 drives vertical shaft 9 to move up and down through positioning block 10.

[0030] In practical use, the rotation of motor 5 enables the rotation of the rotating arm 4, the rotation of motor 8 enables the rotation between the support plate 6 and the rotating arm 4, motor 18 drives the rotation of the vertical shaft 9, and motor 24 drives the vertical shaft 9 to move up and down.
