The utility model discloses an
ankle joint artificial limb adjusting mechanism which comprises an
ankle joint artificial limb, at least two gears are arranged in the
ankle joint artificial limb and correspond to each other, one side of each gear is fixedly connected with a supporting shaft, the
lower half portion of each supporting shaft is fixedly connected with a driving
pulley, and the
lower half portion of each supporting shaft is fixedly connected with a driving
pulley. The end, away from the gear, of the supporting shaft is rotationally connected with the ankle joint artificial limb, the driving
pulley is connected with a screw in a meshed mode, a driven pulley is arranged on one side of the driving pulley, a guiding pulley is arranged on one side of the driven pulley, and a stress pulley is arranged on one side of the guiding pulley. The stress pulley and the guide pulley are installed at the corresponding positions. According to the
ankle joint prosthesis, the supporting plate is arranged and can rotate by a certain angle according to the size of a shoe, so that the
ankle joint prosthesis can be tightly attached to the shoe, the situation that a user is hurt due to the fact that the shoe falls off or loosens in the walking process is avoided, and the wearing stability of the
ankle joint prosthesis is improved.
