The construction wrench is a commonly used tool in construction projects. It is mainly used to tighten and loosen bolts, nuts and other threaded fasteners. According to different work requirements and bolt specifications, there are many types of construction wrenches, such as adjustable wrenches, fixed wrenches, plum wrenches, hexagonal wrenches, etc.

[0003] Many of the existing wrenches used in construction projects are for high-altitude operations. Because the construction project is still under construction, there are often many deficiencies, which makes it inconvenient for workers to work at heights. As a result, when working at heights, they need to carry a large number of tools to avoid the need to get tools up and down from heights during work. However, when workers carry a large number of tools to work at heights, the weight of the large number of tools will bring a great burden to the workers, resulting in a high labor intensity for the workers when working at heights. Therefore, the present application proposes a multifunctional wrench for construction use to solve the above technical problems. Utility Model Content
