Description

Adjustable wrench

Technical Field

The utility model belongs to the technical field of hardware and tools, a shifting wrench for revolving twist nut is related to.

Background

The adjustable spanner is a tool which can be used for screwing or unscrewing nuts with various specifications, and structurally comprises a handle and a nut port which is arranged at the end part of the handle and is formed by a fixed block and a sliding block which can be adjusted through a worm. When the worm-screw driver is used, the nut is sleeved into the nut port, the worm is screwed, so that the sliding block moves to clamp the worm-screw driver, and the worm-screw driver can be screwed. However, because the fixing block and the sliding block forming the nut opening are of corresponding parallel surface structures, namely two corresponding parallel edges for clamping the hexagonal nut, the edges and corners of the nut are easily extruded and deformed during forced screwing, and the nut is damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can effectively overcome the angular extrusion deformation's of nut shifting wrench.

Realize the utility model discloses the first technical scheme of above-mentioned purpose does:

the utility model provides a spanner, includes the handle, set up in the nut mouth that the slider that is formed by the fixed block and can adjust through the worm of its tip, its characterized in that: and corresponding triangular openings are respectively arranged on the working surfaces corresponding to the fixed block and the sliding block.

The additional technical characteristics of the adjustable spanner further comprise that:

a round top hole is formed at the top corner of the triangular notch;

-the angle of the triangular opening is 120 degrees;

-the angle of the triangular opening is 90 degrees;

-the angle of the triangular gap is 135 degrees.

Compared with the prior art, the wrench provided by the utility model has the following advantages: firstly, because the corresponding triangular notches are arranged on the working surfaces corresponding to the fixed block and the sliding block which form the opening of the wrench nut, when the wrench nut is used, four edges forming the nut enter the notches, the torque moment to the nut can be greatly improved, the efficiency of screwing the nut is greatly improved, meanwhile, the extrusion deformation of the edges and corners of the nut can be effectively prevented, and the use effectiveness of the nut is ensured; secondly, because the round top hole is arranged at the vertex angle forming the triangular opening, the protection of the edge angle of the nut during screwing can be effectively ensured.

fig. 2 is a second structural schematic diagram of the monkey wrench.

Detailed Description

The structure of the wrench proposed by the present invention will be further explained with reference to the drawings and the embodiments.

As shown in fig. 1, the utility model provides a structure of shifting wrench schematically, the structure that constitutes this spanner includes handle 1, forms fixed block 3 of nut mouth 5 and can adjust the slider 3 constitution of its size through worm 4, is provided with corresponding its contained angle A and is 120 degrees triangle opening 21, 31 on the working face that above-mentioned fixed block and slider correspond. During the use, go into nut 6 card in the nut mouth, constitute two edges and corners card that the nut corresponds promptly and go into two triangle openings for four edges card that constitute the correspondence of nut are in nut mouth 5, and make two limits that constitute the triangle opening constitute the cladding of two edges and corners that correspond, consequently when wrench movement this nut, can effectively protect the nut edges and corners and prevent the damage to the edges and corners.

In order to further improve the protection of the nut edges and corners and effectively prolong the service life of the nut, as shown in fig. 2, a round top hole 7 is arranged at the top corner forming the triangular opening, namely, when the nut is clamped into the nut opening, the corresponding nut edge and corner entering the triangular opening is suspended, so that when the nut is screwed by moving the wrench, the nut edge and corner is in an unstressed state, and the damage of the wrench to the nut edge and corner can be effectively avoided;

in the structure constituting the above-described monkey wrench:

the included angle A of the triangular notch can be set to be 90 degrees so as to adapt to the use of the quadrangular nut;

the included angle A of the triangular notch can be set to be 135 degrees so as to adapt to the use of the octagonal nut.

Claims (5)

1. The utility model provides a monkey wrench, includes the handle, set up in the nut mouth that the slider that is formed by the fixed block and can adjust through the worm of its tip, its characterized in that: and corresponding triangular openings are respectively arranged on the working surfaces corresponding to the fixed block and the sliding block.

2. The adjustable wrench according to claim 1, further comprising: the vertex angle of the triangular opening is provided with a round top hole.

3. The adjustable wrench according to claim 1, further comprising: the included angle of the triangular notch is 120 degrees.

4. The adjustable wrench according to claim 1, further comprising: the included angle of the triangular opening is 90 degrees.
