Because also include fixed block 25, the second fixed plate 26, motor 27, round wheel 28 and guide rod 29, be connected with fixed block 25 on the wire rope 14, base 1 top is fixedly connected with second fixed plate 26, the second fixed plate 26 tops are equipped with motor 27, and motor 27 front sides are connected with round wheel 28, and the eccentric position rotation formula of round wheel 28 front sides is connected with guide rod 29, and one end of guide rod 29 is connected with fixed block 25 front side rotation formulas. So when the patient's arms pull the handle 19 and get tired, the starter motor 27 rotates, and the motor 27 rotates to drive the round wheel 28 to rotate. 14 Move left and right to drive the first slider 8, the first swing seat 9, the second swing seat 10, the first fixed plate 11, the first spring 13, and the strap 12 to move left and right, and this is repeated, thereby achieving the need for manual pulling of the wire rope 14. Carry out the function of exercising the legs.

Because the wheels 30 are also included, the left and right sides of the bottom of the base 1 are equipped with wheels 30 . So when the device needs to be moved, the pusher is moved by the rotation of the wheels 30 .

The above-mentioned embodiments only express the preferred implementation of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be noted that those skilled in the art can make several modifications, improvements and substitutions without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
