[0002] In industrial production, mechanical maintenance and various DIY handcrafts, wrenches, as a common fastening and dismounting tool, play an indispensable role. The types of traditional wrenches are relatively diverse, such as fixed-size spanner wrenches, open-end wrenches, etc. Although they can provide stable torque in the operation of nuts or bolts of specific specifications, they have a significant limitation, i.e., each wrench can only adapt to workpieces of specific sizes. In actual work scenarios, operators often have to face nuts or bolts of various specifications, which means that they have to prepare a large number of wrenches of different sizes, which is not only inconvenient to carry, but also consumes a lot of time and effort in tool selection and replacement, seriously affecting work efficiency. In addition, in some mechanical maintenance, metal processing and other work, in addition to fastening and dismounting operations, simple finishing work on workpieces is often required, such as removing burrs on the surface of workpieces, polishing uneven parts, etc. In this case, additional tools such as files are required. However, carrying and managing multiple types of tools not only increases the cost of work, but also easily causes the loss or confusion of tools, further reducing the convenience and smoothness of work. Moreover, traditional wrenches mainly focus on fastening functions in design, and do not consider the comfort and safety of operators during use. When using a wrench for a long time, the hands are prone to fatigue due to friction and pressure with the handle, and even may slip, which not only affects the work progress, but also may cause accidental injury to the operator. In summary, the existing wrenches have many shortcomings in terms of functional diversity, use convenience and operation safety, and there is an urgent need for a new type of wrench that can integrate multiple functions, be easily adjusted and safe and comfortable to use to meet the increasingly complex work requirements.
