Description

Technical Field

[0001] The utility model belongs to the field of special disassembly and assembly tools, and in particular relates to a special wrench for disassembling and assembling a threaded locking ring. Background Art

[0002] The threaded locking ring is a commonly used locking workpiece. When the threaded locking ring is in use, a large amount of acetal drying glue is often coated on the bottom of the threaded locking ring to prevent loosening and seal the threaded locking ring. If the workpiece locked by the threaded locking ring needs to be replaced, the threaded locking ring needs to be removed first; when disassembling the threaded locking ring, a certain axial force and torque need to be applied to the four notches on the upper end face of the threaded locking ring at the same time. Due to the strong "anti-disassembly force" generated by the solidification of the acetal drying glue and the limitation of the disassembly space of the threaded locking ring, ordinary tools cannot load the appropriate axial force on the threaded locking ring, and thus it is difficult to load the torque required for disassembly; if an ordinary screwdriver or tweezers is used to disassemble and assemble the threaded locking ring, the threaded locking ring will be subjected to uneven force and will be difficult to disassemble and assemble; using general tools to forcibly disassemble and assemble the threaded locking ring will cause damage to the threaded locking ring.
