摘要: An electric cutting tool (10) has a body (100), a chuck (300) for attaching a saw blade (20) having a rear end (22) including a hole (24), and a drive mechanism (200). The chuck (300) has a gap (312) for receiving the rear saw end (22), an internal multi-part fixing means (340) for engaging the hole (24) of the saw end (22) in the gap (312), and an outer cylinder (330) having an inner cam surface (332) for acting upon the fixing means (340). The cylinder (330) is manually rotatable between a locked position in which the cam surface (332) presses the fixing means (340) tight against the saw hole (24) in the gap (312) to fix the saw blade (20) and an unlocked position releasing the fixing means (340). The fixing means (340) is provided by two balls (342 & 344).
