[0026] Specifically, by starting the motor 14, its output end drives the rotating shaft 15 and the worm 16 to rotate, and meshes with the special-shaped worm gear 17 on the columnar block 7, so that the adjustment block 10 on the hollow block 12 can slide in the slide groove 9 in the columnar block 7, driving the pressure plate 13 to deflect within 180 degrees.
