PROBLEM TO BE SOLVED: To enable connection by an inexpensive structure, to enable drive only in a connected state, and to enhance safety, in an electric bush cutter of a divided-pole type which can be made compact in size at transportation and accommodation.SOLUTION: In an electric working machine having a power supply part for holding a battery at a rear end of a pole, and attached with a working apparatus at a front side of the pole, the pole is divided by a fixed pipe 40 and an extension pipe 80, and the fixed pipe and the extension pipe are fixed by a detachable holder 50. Power is supplied to a motor side from the battery by power lines 35, 85, and when the pole is fixed by the holder 50, the power lines 35, 85 are connected to each other by a conductive member 57 embedded in the holder 50. Since a motor can be driven only when the fixed pipe and the extension pipe are connected by the holder 50, work in an incompletely-fixed state can be prevented.COPYRIGHT: (C)2015,JPO&INPIT【課題】運搬時、収納時にはコンパクトにできる分割竿方式の電動刈払機において安価な構造で連結可能とし、連結状態でのみ駆動可能として安全性を高める。【解決手段】竿の後端にバッテリを保持する電源部を設け、竿の前方側に作業機器が取り付けられる電動作業機において、竿を固定パイプ40と延長パイプ80にて分割し、これらを着脱可能な保持具50にて固定するように構成した。バッテリからモータ側への電力は電力線35、85によって供給され、保持具50にて竿を固定した際に、保持具50に埋め込まれた導通部材57によって電力線35、85が接続されるようにした。このように保持具50にて固定したときのみモータが駆動可能となるので、不完全な固定状態で作業を行うことを防止できる。【選択図】図8
