A power tool has a driving shaft for driving a working element and a clamping device for clamping the working element. The clamping device has a clamping position in which the working element may be fixed relative to the driving shaft and a release position in which the working element can be removed from the driving shaft. An operating member is coupled to the clamping device for moving the clamping device between positions. The clamping device also has a rotating position in which the working element can be rotated by an angle relative to the driving shaft and the operating member has an operating position that corresponds to the rotating position.
