Description

Technical Field

[0001] The utility model relates to an adjustable spanner. Background Art

[0002] Traditional adjustable wrenches use a head rotating method to adjust the distance between the clamping heads to adapt to nuts or bolts of different sizes. However, in actual use, the connection of the clamping heads may not be firm or stable enough, resulting in the clamping heads being easily loosened or failing during use, affecting the performance and reliability of the wrench. At the same time, traditional adjustable wrenches cannot meet the requirements of adjusting nuts or bolts of different sizes in narrow spaces, and the use effect is poor. Therefore, an adjustable wrench is proposed. Utility Model Content

At the same time, the traditional adjustable wrench cannot meet the adjustment of nuts or bolts of different sizes in a narrow space, and the use effect is poor.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an adjustable wrench, comprising a handle, one end of the handle is provided with a clamping plate A, an adjustment component is provided inside the handle, the handle is connected to a clamping plate B through the adjustment component, and the clamping plate B is located on the side of the clamping plate A away from the handle,

[0005] Wherein, the handle adjusts the distance between the clamping plate A and the clamping plate B through the adjustment component.

[0006] Preferably, the adjustment assembly includes an adjustment screw disposed inside the handle, the outer periphery of the adjustment screw is cooperatively connected with a threaded sleeve, and the threaded sleeve is connected to the clamping plate via an arc bridge.

[0007] Preferably, one end of the adjusting screw is connected to an adjusting knob, and the adjusting knob is located at the end surface of the handle away from the clamping plate A.

[0008] Preferably, a rotation groove is provided on a side of the adjusting knob closer to the handle, so that the adjusting knob can rotate at the handle.

[0009] Preferably, one end of the handle away from the clamping plate A is provided with a rotating ring plate that cooperates with the rotating groove.

[0010] Preferably, a groove for accommodating the adjusting screw is provided inside the handle so that the adjusting screw can rotate inside the handle.

[0011] Preferably, a guide groove for linear movement of the screw sleeve is provided on the side of the inner groove closer to the clamping plate A.

[0012] Preferably, the upper parts of the clamping plate A and the clamping plate B are both chamfered, and clamping pads are provided on opposite sides of the clamping plate A and the clamping plate B.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model can quickly adjust the distance between the clamping plate A and the clamping plate B by means of the adjustment component, so that the wrench can adapt to nuts or bolts of different sizes, providing a wider range of applications.

[0015] The adjustment component adopts the structure of adjusting screw and screw sleeve, and the distance between the clamping plates can be easily adjusted by rotating the adjusting knob. The adjusting knob is also designed to be located at the tail end of the handle. This design allows the distance between clamping plates A and B to be adjusted by the adjusting knob at the tail end when the wrench is inserted into a narrow space. Compared with the traditional adjustable wrench, the adjustment process is simple and quick, which improves the use efficiency.

[0016] The clamping plate B is connected to the handle through the adjustment assembly. After the adjustment is completed, the adjustment knob can be held to prevent the adjustment screw from deflecting and ensure a firm and reliable connection. This design ensures the stability and reliability of the wrench during use and avoids the problem of the clamping head loosening or failure.

[0017] The conventional adjustable wrench is less effective in adjusting nuts or bolts of different sizes in a narrow space, while the adjustable wrench of the utility model has the characteristic that the clamping plate B is located on the side of the clamping plate A away from the handle, which can better meet the working requirements in a narrow space.

[0018] The chamfering of the clamping plates A and B and the addition of the clamping pads improve the clamping ability of the wrench to the nut or bolt, and increase the stability and safety of the work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to solve the problem that the connection of the clamping head of the traditional adjustable spanner may not be firm or stable enough, which causes the clamping head to loosen or fail easily during use, affecting the performance and reliability of the spanner, and the traditional adjustable spanner cannot meet the adjustment of nuts or bolts of different sizes in a narrow space, and the use effect is poor, the embodiment of the utility model provides an adjustable spanner. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.
