| titleOfInvention | Pipe wrench structure |
| abstract | The invention relates to a water pipe wrench structure, comprising a ratchet block, the pivot shaft of which is sheathed with a torsion spring; the ratchet block is located between a first clamp arm and a second clamp arm, the pivot shaft is connected to the first clamp arm and the cross pivot point of the second clamp arm; the first clamp arm is provided with a long opening with a ratchet segment, the ratchet block is located in the long opening, the short spring foot of the torsion spring is fixed on the ratchet block, and the long spring The foot pushes against the smooth side wall of the long opening, and the ratchet block engages with the ratchet segment; the ratchet block also includes an eccentric shaft pivoted through the arc-shaped hole of the second clamp arm. By pulling the second clamp arm in two stages, the arc-shaped hole can use one end wall to push against the eccentric shaft and then push and rotate the ratchet block, disengaging from the engagement with the ratchet segment, so that the second clamp arm can move down and change the water pipe. The size of the jaws of the pliers provides a moderate idle stroke rotation angle, which can moderately loosen the jaws to adjust the operating posture without affecting the engagement state of the ratchet block and the ratchet segment, so as to improve the traditional ratchet block. The problem of easy disengagement. |
