The rotation of the planet wheel 8 has two modes, one is that the sun wheel 7 drives the planet wheel 8, and the planet wheel 8 drives the rotation shaft 5 to work. However, since the revolution wheel 9 is rotationally connected with the smooth part of the rotation shaft 5, the rotation of the gear part of the rotation shaft 5 can not drive the revolution wheel 9 to work, i.e. the rotation of the planet wheel 8 can not automatically cause the revolution of the planet wheel 8. Under the condition that the hand crank 3 is inserted into the hand crank 4, the hand crank 4 drives the revolution wheel 9 to work, the revolution wheel 9 is rotatably mounted on the smooth part of the rotating shaft 5, and the synchronous disc 10 is rotatably mounted on the output end of the motor 2.

The revolution wheel 9 rotates to drive the planet wheel 8 to revolve, and the revolution wheel 8 can drive the rotating shaft 5 meshed with the small part of the planet wheel 8 to work. Since the revolution of the planetary gear 8 does not cause the sun gear 7 to operate, the planetary gear 8 in the revolution mode does not spontaneously cause the planetary gear 8 to spin. The rotation mode and revolution mode of the planet wheel 8 are independent of each other and do not affect each other, and the two modes can work independently or together.
Various other corresponding changes and modifications will occur to those skilled in the art from the foregoing description and the accompanying drawings, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
