steel wire rope, and the second rectangular channel phase of setting on the sheaves length direction on of the second rectangular channel The logical cavity in concave；The length and width of the length and width and hinge of the second rectangular channel match, and one end of steel wire rope is fixedly connected On hinge, in annular shape, locking post is by hanging over steel with the integrally formed crotch of locking post for the termination of the other end of steel wire rope Cord on circular termination, locking post is made up of metal material, engage post cylinder with diameter greater than the first rectangular channel Width, height and the height in the middle part of hinge of the mid portion of cavity match, and the entire length and height of cavity are to allow The resupinate size of hinge, upper sheaves by several bolts be tightened in it is upper shearing tool rest on, the middle part of cavity just under To be arranged on the side screwed hole of shearing tool rest, near the side of upper shearing tool rest, the width of hinge is little for the side screwed hole for side In the aperture of side screwed hole；Nut is fixedly installed below the hinge and puts mechanism, the nut puts mechanism includes one Bottom surface is provided with the cylindrical connecting plate being fixed on below hinge of cylindrical blind hole, the hole of the cylindrical blind hole Stopper is installed with wall, matching on the lateral wall of the nut is provided with and the corresponding prodger of stopper, the prodger One end is hinged on nut, and the other end of prodger is connected in the groove arrange on nut lateral wall by spring, in connection Be additionally provided with the ring baffle for preventing nut from dropping near the circumference of the
