The strength can only make the wheelchair move gradually. It is not only laborious and not easy to operate. The self-help wheelchair is not equipped with a supplementary force mechanism. If you push the wheel temple, you will reduce the friction force. It is easy for the user to produce slippage due to the large force, which not only causes discomfort, but also hurts when the hand valley touches other components on the wheelchair.
