Description

An adjustable wrench with adjustable inclination angle

technical field

The utility model relates to an adjustable wrench, which belongs to the improvement of the structure and function of the adjustable wrench, in particular to an adjustable wrench with an adjustable inclination angle.

Background technique

At present, the adjustable wrench is a tool for tightening or loosening parts, and is widely used. Various adjustable wrench tools are relatively mature, but there are still some problems. The adjustment range of the traditional adjustable wrench is small, and the angle of adjustment is limited and fixed.

Although the existing adjustable wrench is applicable to nuts or screws of different sizes, when the existing adjustable wrench intends to rotate the nut or screw located in the narrow space, since the wrench of the existing adjustable wrench is oblique to the shank. It is straight and the structure cannot be changed. Therefore, the existing adjustable wrench can hardly turn the nut or screw located in the narrow space, especially the installation and disassembly of the faucet under the kitchen sink. Due to the small space and a certain depth, the ordinary wrench is completely It is inconvenient to operate and needs to be improved. Therefore, an adjustable wrench that has a large working range and can be adjusted at various angles is needed.

The wrench head of the ordinary adjustable wrench is relatively large, which is inconvenient to wrench in a narrow space, and needs to be improved. At the same time, the occlusal surfaces of the fixed wrench and the movable wrench of the ordinary adjustable wrench are parallel and smooth, and cannot be used to twist the pipe. , and sometimes even after adjusting the size of the adjustable wrench and the nut, it will be difficult to loosen and remove the nut due to slipping. The utility model aims to provide a multifunctional movable wrench with large clamping force, no looseness, and the ability to prevent the outer hexagons of the nut from being rounded, and at the same time, to be used to twist nuts or pipes in narrow spaces.

Utility model content

Aiming at the lack and insufficiency of the existing movable wrench structure and operation, the utility model designs and improves a movable wrench with adjustable inclination angle, which can provide a convenient operation by changing the structure of the wrench head and the wrench handle. And the purpose of adjustable wrench angle adjustable, its structure is reasonable, easy to use.

The utility model comprises a handle and a wrench head. The wrench head includes a fixed wrench, a movable wrench, an accommodating groove and a rotating screw rod. The screw is set in the accommodating groove, and the rotating screw meshes with the tooth row to make the movable wrench slide. The upper part of the handle is provided with a fitted groove that can make the wrench head rotate, which can be used to adjust the inclination angle of the wrench head, and has The butterfly lock nut is also provided with a rotatable fitted slot line at the lower part of the handle; a hollow slot hole is provided in the middle of the rear end of the handle; anti-slip teeth are provided on the occlusal surface of the fixed wrench and the movable wrench, And the fixed wrench is not parallel to the occlusal surface of the movable wrench, and has a small inclination angle, forming a trapezoidal surface with a large outer opening and a small inner opening after opening.

The accommodating groove of the utility model is arranged in the center of the wrench head, and the wrench head and the wrench handle are in a straight line, which is more convenient to use in a narrow environment. Compared with the movable wrench, the ordinary wrench is smaller, and the arc of the wrench periphery is reduced to facilitate the use in a narrow environment.

Since the fixed wrench and the movable wrench are opened to form a trapezoidal jaw with a large outer mouth and a small inner mouth, anti-slip teeth are symmetrically and evenly arranged on the occlusal surface between the fixed wrench and the movable wrench. , so the clamping force is large, it will not loosen, it can prevent the outer hexagon of the nut from being rounded, and it can loosen the nut that is difficult to loosen; it can also be used to twist the pipe, and can play the role of a pipe wrench.

The two ends of the hollow slot hole of the utility model are inner hexagonal, which are formed by serial connection of three inner hexagonal hollow slot openings of different sizes and continuously distributed.

The utility model has reasonable design, simple structure, convenient use and easy adjustment, and is suitable for use in a narrow space environment.

detailed description

In conjunction with the accompanying drawings, the working conditions of an adjustable wrench with an adjustable inclination angle will be described in detail below.

As shown in Figure 1 and Figure 2, the utility model includes a handle 1 and a wrench head 2, the front end of the wrench head 1 is provided with a fixed wrench 3 and a movable wrench 4, the fixed wrench 3 is arranged at one end of the head, and the movable wrench The bottom of the wrench 4 is provided with a tooth row 7, and the rotating screw 6 is arranged in the accommodating groove 5. The rotating screw 6 meshes with the tooth row 7 to make the movable wrench 4 slide. The upper part of the handle is provided with a wrench head Part 1 rotates a fitted groove line 9, and has a butterfly lock nut 10, a rotatable fitted groove line 11 is also provided at the lower part of the handle 1, and a hollow slot hole 12 is provided in the middle of the rear end of the handle 1; Anti-slip teeth 8 are all provided on the occlusal surfaces of the fixed wrench 3 and the movable wrench 4.

The fixed wrench 3 of the movable wrench of the utility model is not parallel to the occlusal surface of the movable wrench 4, and has a small inclination angle. After the jaws between the fixed wrench 3 and the movable wrench 4 are closed, a symmetrical triangle is formed, and the fixed wrench 3 After opening between the movable wrench 4, a trapezoidal surface with a large outer mouth and a small inner mouth is formed, and non-slip teeth 8 are symmetrically and evenly arranged on the occlusal surface between the fixed wrench 3 and the movable wrench 4.

The adjustable wrench of the present utility model can form a series of size changes in proportion to facilitate the use in different environments. The angle between the opposite surface of the fixed wrench 3 and the movable wrench 4 and the vertical surface is 6-9 degrees. To provide greater clamping force.

When in use, adjust the position of the movable wrench 4 by adjusting the screw rod 6, so that the middle part of the clamp between the fixed wrench 3 and the movable wrench 4 is slightly larger than the nut or pipe to be turned, and the upper and lower parts of the handle can be adjusted respectively. Fitted groove line, clamp the nut or pipe to be turned to the lower part of the jaw, because there are anti-skid teeth 8 on the wrench, so the nut or pipe to be turned can be clamped tightly, so as to complete the tightening or loosening open.

The utility model has a light and flexible structure, is convenient to use, improves work efficiency, has strong practicability, and is suitable for use in a narrow space environment.
