The bench consists of a shaft with screw thread being formed on it, a foot part gearing the shaft capable of moving up and down by rotating the shaft, operating bar and a converting mechanism. The function of the converting mechanism is to convert reciprocates of the operating bar to rotational motion of the shaft. The operating bar can be operated to rotate the shaft, so as to adjust the vertical position of the foot part.
