Description

Convenient pipe wrench

Technical Field

The utility model relates to the technical field of manual hardware tools, in particular to a convenient pipe wrench which is opened by pressing, automatically adapts to the size of a pipe fitting, automatically releases the clamping of the pipe fitting by rotating in a reverse direction, and is convenient and quick.

Background

At present, when pipe fittings are twisted, a common pipe wrench needs to rotate a nut to adjust the size of a jaw opening, the adjusting time is long, labor is wasted, and the working efficiency is low.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a convenient pipe wrench.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the jaw face of the fixed jaw is milled with tooth-shaped teeth facing to the opening direction, the jaw face of the hook movable jaw is milled with tooth-shaped teeth opposite to the jaw face of the fixed jaw, the jaw face of the hook movable jaw is fixed at the front end part of the jaw body through the rivet, a groove is arranged beside the end part, round holes are arranged at two sides of the groove, an upper limiting wall and a lower limiting wall are arranged between the front end part of the jaw body and the groove, the other end of the hook movable jaw is provided with a round hole, the pin shaft penetrates through the round hole of the hook movable jaw and the torsion spring and is fixed in the round holes at two sides of the groove of the jaw body through the snap spring, one end of the torsion spring is pressed at a position between the upper limiting wall and the lower limiting wall of the jaw body, the other end of the hook movable jaw is pressed at one end of the hook movable jaw, and the jaw face of the hook movable jaw can be pressed towards the fixed jaw face all the time through the pressing force of the torsion spring, the opening surface of the hook movable jaw and the opening surface of the fixed jaw can keep a certain minimum opening size through the upper limiting wall, the maximum opening size of the opening surface of the hook movable jaw and the opening surface of the fixed jaw can be limited through the lower limiting wall, the twisting position of the torsion spring can not exceed the limit position, the service life of the torsion spring is protected, when in use, the opening surfaces of the fixed jaw and the hook movable jaw are twisted to a pipe fitting required, the hook movable jaw is automatically opened and can automatically adapt to the size of the pipe fitting, the pipe fitting automatically slides into the working positions of the fixed jaw and the hook movable jaw, force is applied to the handle part of the plier handle body according to the direction of figure 4, the hook movable jaw and the fixed jaw automatically compress the pipe fitting and can twist the pipe fitting, when force is applied to the handle part of the plier handle body in the opposite direction, the hook movable jaw automatically releases the clamping of the pipe fitting, so that the jaw easily rotates around the pipe fitting, when the pipe fitting reaches a proper position, force is applied according to the direction of the figure 4, and the pipe fitting can be twisted, so that the function of the pipe wrench is repeatedly and easily realized.

The utility model has the advantages of reasonable design, simple structure, easy manufacture, time and labor saving, convenient use and high working efficiency.
