Abstract
A hand-held machine such as a cleaver or cutter having an engine as the driving source and wherein the drive shaft pipe is formed by telescopically extendable pipe members provided with a fixing means for fixing the pipe members relative to each other. The rotational force of the engine is transmitted to the cutter member via a first drive shaft having a circular section, at least one-way clutch and a second drive shaft on the side of the cutter member, to thereby minimize the size of the device for convenient transportation/storage, to improve the work efficiency, and to secure the safety of the operator.
