[0003] Background introduction: A wrench is a mechanical tool mainly used to rotate or tighten nuts, bolts, pipes and various fasteners. Wrenches are essential tools in the fields of machinery, plumbing, construction, etc., used for routine tasks of tightening and loosening parts. The main function of a wrench is to rotate nuts and bolts. Wrenches are usually designed to grasp these nuts and bolts and apply the necessary rotational force to tighten or loosen them. In addition, wrenches can be used to tighten (clockwise) and loosen (counterclockwise) nuts and bolts. Traditional wrenches include open-end wrenches, combination wrenches, socket wrenches, pipe wrenches, torque wrenches, etc.

[0004] Using a traditional wrench manually can require a lot of physical effort, especially when working with large fasteners. This can lead to fatigue and potential injury. Additionally, using a traditional wrench can be too time-consuming because they require constant turning and pulling. Many wrenches require the use of both hands to perform routine tasks, especially when working with nuts with long threads, which can present challenges when workers need one hand for another task or to keep steady. Operators, both professionals and DIY operators, would like an improved wrench that can be used to connect and adjust pipes and nuts with long threads.

[0005] The ratchets of many conventional wrenches are not compatible with power tools and are not suitable for connecting and adjusting nuts in a small space. In addition, operators need to carry wrenches of different sizes, which is expensive and difficult to store. People hope to have an improved wrench to overcome the problems of the prior art.

[0006] Therefore, there is a long-standing need in the art for an improved wrench device that combines the functionality of a traditional ratchet wrench with the power of a power tool.
