Claims

[Scope of utility model registration request]

A through hole is provided in the socket attachment part of the main shaft of the tightening tool, which is perpendicular to the shaft center, a threaded part is formed at one end of this hole, and a pipe-shaped bushing with a threaded part formed on the outer periphery is screwed into this threaded part. one end of a plunger formed in the shape of a stepped rod is attached to the hole in the bush so that it cannot be pulled out but is slidable, and a spring is provided between the bush and the plunger to press the plunger in the projecting direction. Socket mounting structure for tightening tools.
