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.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a cross-sectional view of the head of the present invention.
Figure 3 is a force diagram of the utility model as it is inserted into a pipe.
Fig. 4 is a force diagram of the present invention in twisting a pipe.
The labels in the figure are: 1. the pliers comprise a plier handle body, 2 fixed jaws, 3 eave tile movable jaws, 4 rivets, 5 snap springs, 6 pin shafts, 7 torsion springs.
Detailed Description
As shown in figure 1, a convenient pipe wrench comprises a wrench handle body 1, a fixed jaw 2, a hook movable jaw 3, a rivet 4, a clamp spring 5, a pin shaft 6 and a torsion spring 7, wherein the jaw face of the fixed jaw 2 is milled with tooth-shaped teeth facing to an opening position, the jaw face of the hook movable jaw 3 is milled with tooth-shaped teeth opposite to the jaw face of the fixed jaw, the convenient pipe wrench is characterized in that the fixed jaw 2 is fixed at the front end of the wrench handle body 1 through the rivet 4, the other end of the hook movable jaw 3 is provided with a round hole, the pin shaft 6 passes through the round hole and the torsion spring 7 and is fixed on the wrench handle body 1 through the clamp spring 5, the jaw positions of the hook movable jaw 3 and the fixed jaw 2 are placed on a pipe fitting needing to be turned, force is applied according to the direction of figure 3, the hook movable jaw 3 can be opened according to the size of the pipe fitting, the pipe fitting can slide into the working position formed by the hook movable jaw 3 and the fixed jaw 2, force is applied to the handle part according to the direction of figure 4, the pipe fitting can be turned, when the handle applies force in the opposite direction of figure 4, the hook head movable jaw 3 can automatically loosen the clamping of the pipe fitting, the pipe tongs are easily rotated to a proper position, then the force is applied in the direction of figure 4, the pipe fitting can be turned again, and the process is repeated.
The utility model has the advantages of reasonable design, simple structure, easy manufacture, time and labor saving, convenient opening adjustment, automatic adaptation to pipe fittings and great improvement of working efficiency.
