Background

With the cost compression of new energy lithium batteries, the application space of the lithium batteries is further released in the non-motor vehicle industry. Lithium battery non-motor vehicles have many advantages compared to conventional lead acid batteries, and thus new energy non-motor vehicles are gradually emerging in ordinary households. Since the motor of the non-motor vehicle is integrated in the rear wheel, the rear wheel needs to be detached first during maintenance. At present, in some maintenance points, an electric wrench is used for disassembling nuts of rear wheels. The electric wrench has the advantages of flexibility and labor saving, and also has the defect that the electric wrench needs to be found in full after a motor wire is mistakenly driven and a nut is unloaded during disassembly. Particularly in winter, the motor wire is hardened by cold, and if the wire is hit, the wire is easy to break. The reason that the nuts are found in the full space is that the ground of a maintenance point is disordered, and in addition, the maintenance personnel have no habit of collecting the nuts at the first time of dismounting, and sometimes the nuts are wrongly mounted when being mounted. In particular, one side of the rear wheel is often fitted with two nuts.
