A limiting sleeve is threadedly connected to the mounting portion, and the outer end of the limiting sleeve abuts the inner end surface of the second external gear. The abutment of the limiting sleeve against the inner end surface of the second external gear effectively limits the second external gear, preventing it from loosening. A locking sleeve is threadedly connected to the mounting portion, and the outer end of the locking sleeve abuts the inner end surface of the limiting sleeve. The abutment of the locking sleeve against the inner end surface of the limiting sleeve effectively limits the limiting sleeve, preventing loosening of the second external gear and the limiting sleeve. The outer wall of the first external gear is provided with a through hole for the screws to pass through, and the through hole is provided with a boss. The end face of the screw head can abut against the boss. A spline is provided in the middle of the gear body.
