Multi-head cooperative wrench

A multi-head cooperative wrench comprises a box body, a plurality of working arms and wrench working heads, one end of each working arm can rotate around a rotating shaft on the box body, the wrench working heads are installed at the other ends of the working arms, and the rotating axis of each wrench working head is parallel to the axis of the rotating shaft on the box body. The utility model relates to the field of mechanical tools. According to the multi-head cooperative wrench, when tightly-matched parts are disassembled and assembled by overcoming friction force between assembling faces through thread jacking pressure, a plurality of screws can be screwed at the same time in a cooperative mode, so that the stress uniformity of the disassembled and assembled parts in the axis directionof an assembling shaft hole is guaranteed, meanwhile, the disassembling and assembling efficiency is improved, and the disassembling and assembling process is simple, convenient and fast. 一种多头协同扳手，包括盒体、工作臂、扳手工作头，所述工作臂有若干个，其一
