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
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.

The specific embodiment:
Pipe wrench maybe can meet the requirements of other metal material processing by structural alloy steel and make
The hinge place of moving jaw (1) is processed as cross drilling behind the groove, insert in the groove of caliper after caliper (4) boring, the alignment of three holes, insert in hinge axis (2), hinge axis (2) radially uses rivet to fixedly connected with caliper (4), process a radial slot (9) at an end of hinge axis (2), the outer side plane of the groove of moving jaw (1) bores an aperture (8), one end of torsionspring (3) is loaded in the radial slot (9) of hinge axis, the other end inserts in the aperture (8) of said moving jaw (1), one section extra heavy pipe of front end welding of pincers handles (5), weld after the outer silk of car internal thread and caliper (4) is connected, the front end overstriking of Telescopic handle (7) cooperates with the endoporus that clamps handles (5), afterwards, cover jump ring and fixed cover (6), again with fixed cover (6) with manage handle (5) by being threaded.
During use, moving jaw (1) is pulled open, be stuck in the surface of the work of required rotation, adjust the length of expansion link and can use.
Claims (2)
1, 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).
2, a kind of self-locking pipe wrench according to claim 1 is characterized in that an end of torsionspring (3) is connected on the osculum (8) in the outside, moving jaw (1) hinge place, and the other end is connected in the radial slot (9) of hinge axis (2).
