Abstract

The utility model discloses a wrench, which comprises a pliers handle and a jaw. The pliers handles are divided into two symmetrical strip structures connected by hinges; Jaws are respectively symmetrically opened, and each jaw is in a semi-hexagonal shape. A variety of bolt types are integrated on the wrench, which can work conveniently and quickly, saving the trouble of changing wrenches, one at most.

Description

wrench

technical field

The utility model relates to a tool which can be used for loading and unloading hexagonal bolts, in particular to a wrench which can be used for loading and unloading various bolts. the

Background technique

At present, people often use wrench tools in sheet metal processing, especially when encountering bolts, they usually use torx wrench, but each torx wrench has only two plate heads, which are only suitable for two kinds of bolts, so It is very inconvenient to use. However, although there is an adjustable wrench that can adapt to more bolts, because only two sides of the bolt are under force when the bolt is screwed, it is easy to deform the bolt, causing the bolt to slip off and damage the parts, so the disadvantages are also obvious. the

Contents of the invention

In order to solve the above problems, the utility model proposes a wrench, which is not easy to slip, and can easily tighten or unscrew the bolt without deforming it. the

Based on the above purpose, the technical solution of the present utility model is: a wrench, including a pliers handle and a jaw, the pliers handle is divided into two symmetrical elongated structures and connected by hinges; On the top, from top to bottom, there are respectively symmetrical jaws, and each jaw is in the shape of a half hexagon. the

It also includes two pairs of auxiliary spanners, and the two pairs of auxiliary spanners are respectively connected to the lower end of each pliers handle through hinges. the

The end surface of the auxiliary wrench has a semicircular arc structure, and semicircular arc-shaped grooves are sequentially distributed on the pliers handle, and the auxiliary wrench is located in the groove. the

The combined shape of the two jaws is a slightly open inner hexagon. the

Beneficial effect

1) A variety of bolt types are integrated on the wrench, which can work conveniently and quickly, saving the trouble of changing wrenches, one at most;

2) Add a pair of wrenches to make it easier to grasp by hand and increase the torque. Plus, it can be folded to save space.

Detailed ways

As shown in Figures 1 to 3, the wrench includes a pliers handle and a jaw. The pliers handle is divided into two symmetrical strip structures and connected by hinges; Jaws are respectively symmetrically opened from top to bottom, and each jaw is in the shape of a half hexagon. Also included are two pairs of secondary wrenches, which can be reversed to increase torque. The two pairs of auxiliary spanners are respectively connected to the lower end of each pliers handle through hinges. The end surface of the auxiliary wrench has a semicircular arc structure, and semicircular arc-shaped grooves are sequentially distributed on the pliers handle, and the auxiliary wrench is located in the groove. The combined shape of the two jaws is a slightly open inner hexagon. When tightening the bolts, use three faces on both sides at the same time, that is, a total of six faces the bolts to bear force, so it is not easy to slip, and the bolts can be easily tightened or loosened without deformation. the

The utility model has the following advantages:

1. A variety of bolt types are integrated on the wrench, which can work conveniently and quickly, saving the trouble of changing the wrench, one at most.

2. Add a secondary wrench to make it easier to grasp by hand and increase the torque. the

3. The auxiliary wrench can be folded to save space. the

Claims (4)
