Description

A multifunctional wrench

technical field

The utility model belongs to the field of power line operation, in particular to a multifunctional wrench.

Background technique

Power line construction and maintenance work is a cornerstone to support the normal operation of the entire power grid system. In this work, the wrench is the most important tool for installing and removing hardware. This tool uses the principle of leverage to turn hexagonal or square bolts, screws, nuts and other tools such as hole or open fastening tools or the same type of wrench to hold bolts or nuts together or used alone.

During the use of the wrench, due to the different sizes of the nuts, the size of the opening needs to be adjusted frequently. For example, when screwing a set of bolts and nuts, it is necessary to use two adjustable wrenches to cooperate with the operation. During the operation, the size of the bolt (cap) passes through the middle. The adjustment screw nut is used to adjust the size of the opening. However, it is very inconvenient to frequently adjust the size of the wrench opening. If the opening is too large, the nut will slip during the twisting process. If the opening is too small, the wrench cannot take out the nut or screw after tightening it, or the rotating nut of the adjustable wrench is corroded and cannot be screwed at all. It is very inconvenient to use time-consuming and labor-intensive operations when operating personnel use adjustable wrench like this. In some height-climbing operations, it is often necessary to use a hammer to strike tools, such as adjusting the position of the hoop. When working at heights, it is inconvenient to carry a hammer, and an adjustable wrench is often used instead, resulting in a shortened service life of the adjustable wrench and premature scrapping.

A handle cover made of rubber is set on the handle, which improves the anti-skid performance of the handle and effectively prevents the wrench from slipping and causing high-altitude fall accidents during high-altitude operations.

As a preference, a clamping groove is provided inside the barb pliers, the clamping groove includes a bottom surface, a first mating surface inclined to one side of the bottom surface, and a second mating surface inclined to the other side of the bottom surface, the clamping groove The opening gradually increases from the inside to the outside. During the use of the universal wrench, the barb pliers and arc pliers do not need to manually adjust the opening size, which can greatly improve the work efficiency of the operators, and the efficiency is more significant in the equipment with many round bolts.

As a preference, the side of the fixed pliers head is provided with a positioning groove for accommodating the hammer, the side wall of the positioning groove is provided with a positioning pin and a spring for pushing the positioning pin to slide into the positioning groove, and the side of the hammer is provided with a A positioning hole matched with the positioning pin, and a slide block that drives the positioning pin to release the cooperation with the positioning hole is provided on the outside of the fixed pliers head. The hammer body and the fixed tong head are detachably connected, so that operators can replace the hammer body according to actual needs when they are on the ground, thereby improving adaptability. The hammer body is fixed by the positioning pin and the spring, which can effectively prevent the hammer body from detaching from the positioning groove. The positioning pin controls the connection with the hammer body through the slider, which is convenient for quick replacement of the hammer body.

Preferably, one end of the hammer body is a plane, and the other end of the hammer body is provided with a pointed tip. The shape of the hammer body can be selected between flat and pointed, which further improves the functionality of the hammer body.

The beneficial effects of the utility model are: (1) reducing jaw adjustment time and improving work efficiency; (2) flexible switching between various functions, good adaptability and versatility, and reducing the number and weight of carrying tools.
