摘要： PROBLEM TO BE SOLVED: To provide handling for an improved power tool capable of substantially reducing the influence of the physical property of a power supply line and thereby avoiding early fatigue of the power supply line with the adjustment of the radius of curvature of the power supply line. SOLUTION: A supporting device 17 for supporting a flexible power supply line 16 at a supporting point A located a distance from the terminal 15 of the flexible power supply line 16 is mounted on a housing 10, the supporting device 17 being rotationally moved in respect to the housing 10 around a first axis almost corresponding to the longitudinal direction of the flexible power supply line 16 at the terminal 15 of the flexible power supply line 16 and around a second axis perpendicular both to the longitudinal direction of the flexible power supply line 16 and to the first axis at the supporting point A. The flexible power supply line 16 is formed by drawing a sufficient large loops 19 to avoid a harmful and sharp curve between the terminal 15 and the supporting point A.
