The motor 4 can drive the mandrel 8 to rotate in the middle of the connection cylinder 5. Two limiting rings 14 are arranged between the outer wall of the mandrel 8 and the inner wall of the connection cylinder 5. A rotating groove is arranged between the limiting ring 14 and the inner wall of the connection cylinder 5. The limiting ring 14 is rotationally connected to the inner wall of the connection cylinder 5 through the arranged rotating groove. The limiting ring 14 is used to limit the mandrel 8 to prevent the mandrel 8 from falling off from the middle of the connection cylinder 5. A rotating interface is arranged between the upper end of the mandrel 8 and the fixing frame 3. The mandrel 8 is rotationally connected to the bottom of the fixing frame 3 through the arranged rotating interface.

[0023] As Figures 1 - 4As shown, at the lower end of the mandrel 8, a first connecting rod 11 and a second connecting rod 15 are provided below the sun gear 6. The first connecting rod 11 and the second connecting rod 15 can rotate below the sun gear 6 through the mandrel 8. The first connecting rod 11 and the second connecting rod 15 are perpendicularly crossed. At both upper ends of the second connecting rod 15, planet gears 7 are provided. The two sets of planet gears 7 mesh with the sun gear 6. When the second connecting rod 15 rotates, the planet gears 7 will revolve along the outer wall of the sun gear 6.
