Water pipe clamp structure

Abstract

The invention relates to a water pipe clamp structure which comprises a ratchet block, and a pivot shaft of the ratchet block is sleeved with a torsion spring in a penetrating mode. The ratchet block is located between the first clamp arm and the second clamp arm, and the pivoting shaft is pivoted with a crossed pivoting point of the first clamp arm and the second clamp arm; the first clamp arm is provided with a long opening with a ratchet section, the ratchet block is located in the long opening, a short spring foot of the torsion spring is fixed to the ratchet block, a long spring foot abuts against the smooth side wall of the long opening in a pushing mode, and the ratchet block is meshed with the ratchet section. The ratchet block further comprises an eccentric shaft which is pivoted in the arc-shaped hole of the second clamp arm in a penetrating mode. By pulling the second plier arm in two stages, one end wall of the arc-shaped hole can be used for pushing the eccentric shaft to rotate the ratchet block to be separated from the engagement with the ratchet section, so that the second plier arm moves downwards, the size of the jaw of the water pipe plier is changed, a proper idle stroke rotation angle is provided, and the jaw can be properly loosened to adjust the operation posture. And the meshing state of the ratchet block and the ratchet section cannot be influenced, so that the problem that a traditional ratchet block is easily disengaged from meshing is solved.

Description

technical field [0001] The present invention is related to hand tools, more specifically, it is a water pipe wrench structure. Background technique [0002] Known plumbing wrench, such as Figure 1 to Figure 4 , with a first pliers body 1 and a second pliers body 2 that are cross-pivoted, the first pliers body 1 is provided with a long slot 4 with a ratchet section 3, and a C-shaped spring 5 is arranged on the second pliers body 2. In the ring groove 10 provided, an arc hole 9 is also established in the ring groove 10, and the second spring foot of the C-shaped spring 5 passes through the arc hole 9, and resists the two end walls of the arc hole 9 respectively, wherein one spring foot Combined with a ratchet block 6 , the ratchet block 6 is accommodated in the slot 4 and rotates synchronously with the rotation of the second pliers body 2 . [0003] In operation: to adjust the size of the jaws of the water pipe wrench, it is mainly to reduce and expand the size of the jaws b...

AI Technical Summary

Problems solved by technology

[0005] There is a problem in the combination and operation of the above-mentioned mechanisms, which leads to room for improvement in operation. The problem is that when the jaws are opened, the ratchet block 6 will move with the rotation of the second pliers body 2. "synchronous" is driven to rotate, that is, when the rotation angle of the second pliers 2 is equal to or greater than the meshing size of the ratchet block 6 and the ratchet segment 3, the second pliers 2 will slip off, which This is an overly sensitive phenomenon, which may cause malfunctions during actual on-site operations.
