[0026] The working principle of the utility model is as follows: when in use, the connecting plate 3 is inserted into the slot on the pier 1, and the slider 10 is inserted into the slide slot, and then the baffle 11 is rotated so that the end of the baffle 11 is stuck in the limit frame 12 to block the opening of the slide slot, so as to block the slider 10, and then the handle is pulled to drive the limit plate 18 to drive the moving block 19 to slide and squeeze the spring four 20, and then one end of the connecting rod 4 is passed through the two connecting plates 3 and the pier 1, and the stop handle and the connecting plate 3 are squeezed against the spring one 5, and at the same time, the tooth groove at the bottom of the connecting rod 4 will mesh with the gear 14, so that the connection The rod 4 continuously drives the gear 14 to rotate, and at the same time, the tooth groove at the top of the connecting rod 4 squeezes and pushes the card seat 15, so that the card seat 15 is separated from the tooth groove. At the same time, the card seat 15 pushes the push rod 16 and squeezes the spring three 17. When the tooth groove of the squeezed card seat 15 is misaligned with it, the card seat 15 is reset and moved down under the elastic force of the spring three 17, and this cycle is repeated continuously. After the two connecting plates 3 are preliminarily connected by the connecting rod 4, the connecting shaft of the gear 14 can be driven by manually cranking the hand crank handle, thereby driving the gear 14 to rotate synchronously, so as to apply force, thereby making it convenient for the gear 14 to drive the connecting rod. 4 moves, so that the connecting rod 4 pulls the stop handle at one end to further squeeze the spring 5, until the connecting rod 4 moves to a suitable position, so that the assembly connection between the connecting plate 3 and the pier 1 is realized, which improves the assembly efficiency and is more practical; and when it is necessary to adjust the slider 10 to move toward the pier 1, the adjusting bolt can be twisted out of the corresponding socket, and the handle can be turned to drive the rotating rod 22 to rotate, thereby driving the winding drum 23 to rotate synchronously to wind the wire rope, so that the wire rope pulls the slider 10 to move toward the pier 1 under the guidance of several guide wheels, so as to change the direction of the pier 1. The position of the slider 10 is changed, and the rotation of the rotating rod 22 will drive the ratchet 24, so that the ratchet 24 will squeeze and push the block 25 to rotate, so that it moves to the outside of the ratchet 24, and the block 25 will squeeze the spring 5 26. When the teeth on the ratchet 24 that squeeze the block 25 are separated from it, the block 25 will be reset under the elastic force of the spring 5 26, thereby engaging with the ratchet 24, so as to limit the ratchet 24 and prevent the rotating rod 22 and the winding drum 23 from rotating. The instant adjustment and stop can be achieved, and then the torsion adjustment bolt is inserted into the corresponding socket to improve the fixing effect of the winding drum 23, which is more practical.
