Abstract

The utility model discloses a self locking pipe twist which consists of a movable jaw (1), a hinge axis (2), a clamp body (4), and a clamp handle (5); the distinction is that a torsion spring (3) is connected between the movable jaw (1) and the hinge axis (2), therefore, the holding pipe diameter can be automatically regulated; the structure is simple; the self locking pipe twist is time and labor saving and is especially fit for holding a round work piece; the work efficiency is high; the danger is little.

Description

A kind of self-locking pipe wrench
Technical field:
The utility model relates to a kind of pipe wrench, particularly a kind of self-locking pipe wrench.
Background technology:
At present, the pipe wrench of domestic use needs to adjust the opening degree of adjustable clamp when changing the clamping pipe diameter, wastes time and energy, and in use, often the loosening opening degree of pipe wrench that makes because of nut changes, and industrial accident easily takes place, and brings danger to the operator.
Summary of the invention:
The purpose of this utility model just provides a kind ofly can adjust the clamping caliber automatically, simple in structure, time saving and energy saving, the self-locking pipe wrench of high efficiency.
The purpose of this utility model is achieved in that a kind of self-locking pipe wrench, is made up of moving jaw (1), hinge axis (2), caliper (4), pincers handles (5), it is characterized in that being connected torsionspring (3) between described moving jaw (1) and the hinge axis (2).
An optimum implementation of the present utility model is: an end of torsionspring (3) is connected on the aperture (8) in the outside, moving jaw (1) hinge place, and the other end is connected in the radial slot (9) of hinge axis (2).
The utility model compared with prior art has the following advantages:
Be connected the version of torsionspring (3) owing to adopted between moving jaw (1) and the hinge axis (2), thereby can adjust the clamping caliber automatically, simple in structure, time saving and energy saving, high efficiency, danger is little.
