Description

monkey wrench

technical field

The utility model relates to the field of hardware machinery, in particular to an adjustable wrench.

Background technique

When using the existing adjustable wrench, the clamping distance must be adjusted according to the nuts of different sizes before the nuts can be tightened or loosened, which wastes time and reduces work efficiency. Therefore, we have developed an adjustable wrench. It can directly clamp nuts of different sizes for tightening or loosening, thus improving work efficiency.

Utility model content

The purpose of the utility model is to provide an adjustable wrench to overcome the deficiencies of the prior art, which can directly clamp nuts of different sizes for tightening or loosening, thereby improving work efficiency.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an adjustable wrench, including a fixed head, a fixed handle and a rotating handle arranged at the tail of the fixed head; the fixed head is correspondingly provided with a slidable moving head; The head of the rotating handle is hingedly connected to the moving head, and a rotatable connecting rod is arranged between the head and the middle part of the rotating handle; the other end of the connecting rod is hingedly connected to the tail of the fixed handle.

Preferably, the tail of the fixed handle is provided with a spring connected to the other end of the connecting rod.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The adjustable wrench described in the utility model can directly clamp nuts of different sizes for tightening or loosening, thereby improving work efficiency.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the structural representation of adjustable wrench described in the utility model;

Among them: 1. Fixed head; 2. Moving head; 3. Fixed handle; 4. Rotating handle; 5. Connecting rod; 6. Spring.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1 is the movable wrench described in the utility model, comprises fixed head 1, the fixed handle 3 and the rotating handle 4 that are arranged on the tail of fixed head 1; Said fixed head 1 is correspondingly provided with slidable movable head 2; One end of the rotating handle 4 is hingedly connected with the moving head 2, and the rotating handle is provided with a rotatable connecting rod 5 between the head and the middle, which is relatively labor-saving when clamping using the principle of leverage; the tail of the fixed handle 3 A spring 6 that is hingedly connected to the other end of the connecting rod 5 is provided; when in use: place the nut that needs to be twisted between the fixed head 1 and the moving head 2, and press down the rotating handle 4 by hand, at this time, on the connecting rod 5 Under the support, turn the handle 4 to push the moving head 2 to slide in the direction of the fixed head 1 until the nut is clamped, and then the nut can be tightened or loosened, and the spring 6 plays a protective role during the clamping nut, effectively preventing damage caused by excessive force nuts.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The adjustable wrench described in the utility model can directly clamp nuts of different sizes for tightening or loosening, thereby improving work efficiency.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
