ABSTRACT:
A power tool, which is preferably configured as a right-angle grinder, has a motor-driven hollow spindle to drive a tool, which is fastened between a clamping flange and a counterflange by means of a quick clamping device via a tension spindle, coaxial with the hollow spindle, that is tensioned in the axial direction by means of elastic elements and is displaceable in the axial direction relative to the hollow spindle, by means of a clamping lever, between a clamped position in which the tool is nonrotatably retained between the flanges, and a released position. The clamping lever is mechanically coupled to the motor switch by means of a link rod in such a way that the clamping lever can be moved into the released position only when the motor is switched off. This rules out improper operation and any potential damage to the power tool.
