The planetary gears 7 are arranged on the bearing frame 10, the toothed ring ends of the two sets of transmission mechanisms 2 are respectively arranged in a gap between the hollow rolling shaft 4 and the planetary gears 7 from two sides, and the transmission mechanisms 2 are sleeved on the axle center 3 and are in rotary connection with the axle center 3;
the outer side of the gear ring of the transmission mechanism 2 is meshed with the hollow rolling shaft 4 through an overrunning ratchet mechanism; the inner cavity side of the hollow rolling shaft 4 is provided with a ratchet ring, the outer side of a gear ring of the transmission mechanism 2 is provided with a pawl, and the ratchet ring and the pawl form an overrunning ratchet mechanism. The inner gear ring of the transmission mechanism 2 is meshed with the planetary gear 7, the planetary gear 7 is meshed with the sun gear 8, the bevel gear 9 is fixed on the sun gear 8 to form a whole and sleeved on the axle center 3, the bevel gear 9 is rotationally connected with the axle center, and the bevel gear 9 is meshed with the rotary gear 5.

The rotary gears 5 of the present invention are common knowledge in the art, and the synchronous reverse rotation of the input end and the output end is realized by using the transmission of the two rotary gears 5.

When one pedal is stepped down, the winch rotates, and the other pedal synchronously rises to be used for stepping down next time, and the winch is alternately driven to rotate.
