Claims

[Scope of utility model registration request]

In a hand-held working machine in which a working means is rotatably provided at the tip of a drive shaft pipe and the working means is rotated at high speed via a drive shaft connected to a drive mechanism, the drive shaft pipe is formed to be freely expandable and contractable in the axial direction. On the other hand, the drive shaft is constituted by a circular section shaft on the drive mechanism side and a rotary work side shaft pipe into which the circular cross section shaft is inserted, and one or more one-way clutches are provided at the end of the rotary work side shaft pipe. 1. A hand-held working machine characterized in that a telescopic fixture is further attached to a predetermined location of a drive shaft pipe.
