POWER TOOL

摘要

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.

1. A power tool, comprising:
a driving shaft for driving a working element; a clamping device for clamping the working element to the driving shaft, the clamping device having a clamping position where the working element is fixed relative to the driving shaft and a release position where the working element is removable from the driving shaft; an operating member coupled to the clamping device, the operating member being manually moveable to cause the clamping device to move between the clamping position and the release position; and a flange member connected with the driving shaft and driving the working element; wherein the operating member drives the flange member to move along a longitudinal axis of the driving shaft, the clamping device further has a rotating position in which the working element is clamped on the power tool and free to be angularly rotated relative to the driving shaft, and the operating member is moveable to an operating position corresponding to the rotating position.
