Because the number of teeth of the fourth gear 312 is greater than that of the third gear Therefore, after the transmission of the double gear, the speed of the motor decreases, the torque increases, and the output force increases; the worm 410 also has a deceleration effect. During the transmission between the worm 410 and the second gear 320, the speed of the output shaft of the motor The torque has been reduced, the torque is increased, and the output force of the motor is increased. After further deceleration and torque increase by the first gear 310, the final transmission speed to the gear sleeve 210 will be more stable and the output force will be greater.

Of course, according to the actual situation, in other embodiments, a gear with more teeth than the second gear 320 can be used to be fixedly connected to the output shaft of the motor, the motor is arranged vertically, and the axial direction of the output shaft is the same as the axis of the second gear 320. Since the number of teeth of the gear fixedly connected to the motor output shaft is greater than the number of teeth of the second gear 320, the speed of the motor output shaft will decrease after passing through the second gear 320, and the motor output force will increase.
