[0022] The helix lead angle of the worm 8 is smaller than the equivalent friction angle between the meshing teeth of the worm 8 and the worm wheel 7, so that the worm wheel 7 and the worm 8 can be self-locking. That is, only when the worm 8 rotates can the worm wheel 7 rotate. When the worm 8 does not rotate, the worm wheel 7 and the rotating ring 11 can be automatically fixed, so that the position of the limit plate 5 is also fixed.
