Drive work process as follows using drive rod：
During to pedal gear 6 applying downward pressure, with moving down of pedal gear 6, drive rod 81 drives scroll wheel
83 arcuately slideway 82 movements, thereby pull traction belt 84, and traction belt 84 affects the roller of ratchet mechanism 54 to cover 202, by ratchet
211 and the cooperation of ratchet 205, roller set 202 drive roller cores 201, roller core 201 drives installation axle 52, so that sprocket wheel 5 is along forward
Direction rotate, have in the small flywheel coaxial with trailing wheel 4 ratchet mechanism (using known ratchet mechanism, non-aforesaid ratchet
Mechanism 54), sprocket wheel 5 drives this small flywheel by driving-chain when rotating, and final driving trailing wheel 4 rotates, and the scooter with pedal is
Can move ahead.During this, clockwork spring 193 is tightened savings elastic force.
When not to pedal gear 6 applying downward pressure, with the reset upwards of pedal gear 6, traction belt 84 loses pulling force,
Clockwork spring 193 resets, and drives roller set 202 to rotate backward, and by the cooperation of ratchet 211 and ratchet 205, roller set 202 idle running does not drive
Roller core 201, does not just drive installation axle 52 and sprocket wheel 5 yet.
(" any " mentioned here means three kinds of situations to any alternate run of this device two pedals of guarantee：1st, two step on
Plate pushes simultaneously；2nd, two pedals are one on the other；3rd, a pedal rests, and another pedal back and forth runs).
