The steel wire 55 is sleeved on the outside of the wire wheel 56, and the wire wheel 56 plays a role in changing the direction of the steel wire 55. The steel wire 55 pulls the second toothed slide plate 54 to move toward the center end of the positioning device body 1. The second toothed slide plate 54 is slidably connected to the inner side of the multi-rectangular slide groove 8 through the slider. The movement of the second toothed slide plate 54 drives the gear 53 to rotate, and the gear 53 is rotatably connected to the inside of the multi-rectangular slide groove 8, which is convenient for the gear 5 3 drives the first tooth slide plate 51 to move to the outside of the positioning device body 1, and the first tooth slide plate 51 drives the fixed pressure plate 52 and the double-column slide bar 64 to move, and the double-column slide bar 64 slides out of the oil sliding shell 61, and the double-column slide bar 64 squeezes the spring 63, and the spring 63 plays a role in resetting the double-column slide bar 64.
