Abstract

A leg stretcher for physical education comprises leg supporting plates, a fixing pin and a leg fixator. A round base is arranged at the bottom of a leg stretcher body. A lifting jack is fixed to the upper end of the edge position of the base, and a manually-operated hydraulic rod is arranged on the side wall of the bottom end of the lifting jack. A fixing pipe is arranged at the upper end of the lifting jack through welding, and a supporting rod for leg stretching is embedded in the fixing pipe. Limiting balls are arranged at two ends of the supporting rod for leg stretching through welding. Fixing holes are formed in the inner side ring wall of the supporting rod for leg stretching in an array mode. The fixing pin is fixedly arranged on the inner side wall of the fixing pipe. The fixing pin is composed of a fixing pin rod, a return spring and a hand-pulled plug. Massaging balls arranged at the upper ends of the leg supporting plates of the leg stretcher for physical education facilitate playing a certain massaging effect on the legs stretched by a trainer, the muscle tension brought by training is relieved, and accordingly a training effect is improved.
