Compared with traditional adjustable wrenches and ratchet wrenches, the new adjustable wrench solves several problems during use. First, its wrench head is lengthened to avoid touching the surrounding screws and nuts during operation. Secondly, a wrench handle is added in the middle of the wrench handle, which realizes 360-degree rotation, allowing various screws to be tightened at will. This design not only saves maintenance time and reduces the trouble of frequent tool rotation, but also improves the reliability of screw tightening.

[0003] The traditional method of using a new type of adjustable wrench is as follows: First, hold the handle of the wrench and align the wrench head with the position of the screw or nut. Then, by rotating the handle, the force is transmitted to the wrench head to tighten or loosen the screw. During the operation, if the position of the screw or nut is restricted, the flexibility of the adjustable wrench can be used to adjust the angle of the wrench head to facilitate operation.

[0004] When using the above-mentioned traditional adjustable wrench, the size of the wrench opening is usually changed by rotating the adjustment nut or pushing the sliding mechanism. This process requires two-handed operation and is particularly inconvenient when adjusting in a narrow space, which is not convenient for daily use. Utility Model Content
