Description

technical field

[0001] The invention relates to the technical field of connectors, in particular to a multifunctional easy-to-assemble and disassemble bolt assembly. Background technique

[0002] At present, there is no anti-loosening measure between the pressing surface of the combined bolt and the nut. After a long period of vibration of the equipment, the parts begin to loosen and cause the equipment to fail. Disassembly, but most of the time, because there is no size specification on the bolt and nut, in many cases, the experience of the mechanic is used to judge the size, and then find the corresponding socket or wrench. It is very inconvenient and time-consuming to start the disassembly or assembly work after the corresponding size is determined. Moreover, after the equipment fails, it is almost impossible to know the size of the bolts and nuts to be disassembled. Take a toolbox or tool trolley to the maintenance point for maintenance work, sometimes the tool belt is ...
