[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) During installation, the operator rotates the bolt and inserts it into the threaded hole of the flange nut body for tightening. The anti-slip pattern on the gasket can increase the friction between the gasket and the workpiece, thereby improving the anti-slip effect of the flange nut body. After tightening, the operator pulls the pull ring. When the pull ring is pulled, the pull rod pulls the rack to move. When the rack moves, it drives the slider to slide inside the slide groove, thereby increasing the stability of the rack when it moves. When the rack moves, it drives the gear to rotate along the shaft seat. When the gear rotates, it drives the rotating ring to rotate through the outer gear ring. When the outer gear ring rotates, it drives the limit slip ring to rotate inside the limit ring groove through four fixed rods, thereby improving the stability of the outer gear ring and the rotating ring when they rotate. When the rotating ring rotates, the four pushing bars are driven to rotate and push the four contact balls. When the four contact balls are pushed, the rectangular rods are driven to slide inside the rectangular sleeve through the pushing plates, and the reset springs are squeezed at the same time, so as to ensure the movement stability of the four rectangular rods while making them have the effect of elastic reset. When the four rectangular rods move, the four positioning hoops and four friction pads are driven to clamp and fix the bolts, so as to further increase the anti-slip effect of the nuts. (2) When the pull rod is pulled, it moves along the socket inside the limit block. When the pull rod moves, it drives the two blocks to pass through the two strip grooves. When the pull rod moves, it also drives the two connecting rods to move through the two shaft sleeves. When the two connecting rods move, they drive the two sliding sleeves to slide on the surfaces of the two sliding rods and squeeze the two telescopic springs at the same time. When the block passes through the two strip grooves, the operator drives the pull rod to rotate along the rotating shaft through the pull ring. When the pull rod rotates, the two blocks are driven to correspond to the positions of the two limit grooves. Then the operator releases the pull ring, and under the elastic force of the two telescopic springs, the two blocks are driven by the pull rod to be stuck in the two limit grooves for limiting, thereby achieving self-locking, thereby ensuring the stability of the clamping positioning; (3) This makes the flange nut have good anti-slip ability and can be used in an environment with frequent vibration, thereby meeting the use in an environment with higher anti-slip requirements.
