The utility model relates to a spanner especially relates to a multifunctional spanner.
In the machining and maintenance industry, a wrench is one of the indispensable tools. At present, the types of wrenches are various, but most of the wrenches have the defect or the defect of single function, for example, although the electric wrenches, the hydraulic wrenches, the pneumatic wrenches and the like have the advantages of labor saving and high operation efficiency, the wrenches need to be additionally connected with a power source, the application occasions of the wrenches are also greatly limited, and the wrenches are complex and heavy in structure and cannot be used in working environments with strong mobility, poor working conditions and the like. And when carrying out maintenance work, because the function singleness of most spanners, consequently often need carry multiple spanner, not only loaded down with trivial details but also waste time and energy, still forget on the scene easily, cause the potential safety hazard. If when a welder uses fire welding on a welding site, the oxygen cylinder and acetylene cylinder switch are often required to be opened and closed, a dead-end wrench and an internal square common wrench are usually used at present, but the handle of the internal square wrench is short, labor is wasted, the size is small, and the normal work is influenced to a certain extent.
