1. During use, the patient's feet are respectively placed in the two foot bearing mechanisms. When the foot bearing mechanism is on the second slide rail, the feet exert a linear force so that the foot bearing mechanism moves along the second slide rail. The two slide rails move in a straight line, which has the effect of exercise. When the foot bearing mechanism moves to the junction of the inner end of the first slide rail and the second slide rail, the patient can apply force through the foot to push the foot bearing mechanism Switch from the second slide rail to the first slide rail, and then the foot exerts force along the arc line direction, so that the foot bearing mechanism moves back and forth along the arc line direction of the first slide rail, which also has the function of exercising As a result, the foot bearing mechanism can smoothly switch between linear motion and arc motion, which increases the form of motion, improves the fun of exercise, and can improve the enthusiasm of patients for exercise;

2. During use, the azimuth position of the first slide rail and the second slide rail can be changed by the rotation of the disc.
