A reversible manual variable speed driving device is characterized by comprising a rack, a force application handle, a main power shaft, a one-way overrunning clutch, a reset device, a variable gear set, a reversing gear set, a neutral gear trigger and a reversing trigger. One end of the force application handle is fixed to the input end of the one-way overrunning clutch, the output end of the one-way overrunning clutch is fixed to the main power shaft, the force application handle rotates around the main power shaft in a reciprocating mode to sweep over a fan-shaped face to move and do work, and a driving force arm corresponding to the force application handle directly drives the input end of the one-way overrunning clutch to rotate forwards and backwards. Therefore, the output end of the one-way overrunning clutch is intermittently driven to rotate unidirectionally. The output end of the one-way overrunning clutch is fixedly connected with an input end gear of the change gear set through a main power shaft; and a limiting device for ensuring that the angle is less than 60 degrees is arranged between the force application handle and the rack. The invention further provides the rowing-imitating hand-powered car, reversing driving can be achieved, upper limbs can be exercised, and the boating-imitating hand-powered car can be used for physical exercise and enjoyment.

    一种可换向人力变速驱动装置,其特征在于,包括:机架、施力柄、主动力轴、单向超越离合器、复位装置、变速齿轮组和换向齿轮组、空挡触发器、换向触发器;所述施力柄的一端与单向超越离合器的输入端固定,所述单向超越离合器的输出端固定在主动力轴上,施力柄往复的绕主动力轴旋转扫过扇形面运动做功,施力柄对应的驱动力臂直接驱动单向超越离合器的输入端正反双向旋转,从而间歇的驱动单向超越离合器的输出端单向旋转;所述单向超越离合器的输出端与所述变速齿轮组的输入端齿轮通过主动力轴固定连接;施力柄与机架之间设有确保小于60度的限位装置。本发明还提供一种仿划船手摇车,可实现换向驱动,锻炼上肢,既锻炼身体有享受乐趣。
