The worm and gear transmission module comprises a motor, a worm; the first worm wheel and the second worm wheel are respectively meshed with the worm for transmission, have the same reference diameter, tooth number, modulus and pressure angle, and are respectively provided with a first winding wheel and a second winding wheel; the first winding wheel and the second winding wheel have the same diameter and synchronously rotate with the first worm wheel and the second worm wheel respectively; when the reference diameter of the first worm gear and the second worm gear is a specified length, the number of teeth of the worm gears is a specified number, and the pressure angle of the first worm gear and the second worm gear is a specified size, the first rope and the second rope are fixed. According to the contact friction coefficient between the first worm gear and the worm and between the second worm gear and the worm after the worm gear and worm transmission module performs preset times of actions, the reference diameter of the worm is set to enable the torque borne by the worm in the pulley direction to be smaller than or equal to 0.
