A spur gear 9 is installed on the connecting shaft 7, and the spur gear 9 meshes with the incomplete gears 10. The two driving rods 11 rotate relative to each other to control the synchronous rotation of the two driving rods 11. The driving rods 11 drive the two incomplete gears 10 to rotate accordingly. The two incomplete gears 10 mesh with the spur gear 9 one by one, thereby driving the spur gear 9 to rotate in different directions.
