Since the inner ring gear 19 and the planetary gear 21 are engaged with each other, when the planetary gear 21 rolls along the inner ring gear 19, it will rotate around its own axis and drive the center gear 22 to rotate.

[0040] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present utility model, the revolution drive assembly:

[0041] The turntable 18 is rotatably disposed on the lifting plate 4 via the third rotating shaft 17, and the central gear 22 is rotatably disposed at the center of the turntable 18; a plurality of sets of planetary gears 21 are rotatably disposed on the turntable 18 and are distributed in an annular manner around the central gear 22;
