Lock nut disassembling and assembling tool

The invention relates to the field of nut dismounting and mounting, in particular to a locknut dismounting and mounting tool which comprises a supporting rod. One end of the connector is detachably connected to one end of the supporting rod, and the connector and the supporting rod are coaxial; the pair of shifting teeth is detachably connected to the other end of the connector; and the handle is vertically and detachably connected to the other end of the supporting rod. Due to the fact that the stirring teeth are in threaded connection with the connector, the problem that the stirring teeth need to be integrally replaced and machined after being damaged is effectively solved, only the stirring teeth need to be replaced, and therefore the machining cost is reduced. 本发明涉及螺母拆装领域，具体涉及一种防松螺母拆装工具，包括：支撑杆；连接头，该连接头一端可拆卸连接在支撑杆的一端，且连接头与支撑杆同轴；一对拨动齿，一对该拨动齿可拆卸连接在连接头的另一端；把手，该把手垂直可拆卸连接在支撑杆另一端。本发明由于采用了拨动齿与连接头螺纹连接，有效解决了拨动齿在损坏后需要进行整体更换加工的问题，进而实现了只用更换拨动齿即可，从而减少加工成本。
