    摘要: A machine tool, especially a hand-held power tool, comprises a tool spindle and a clamping element turnably mounted on the spindle, in which the turnable clamping element is arrestable during rotation of the spindle for clamping or releasing a tool mounted thereon to thereby make a separate implement for preventing rotation of the clamping element during clamping or releasing the tool on the spindle unnecessary. In a special embodiment of the present invention the clamping or releasing forces during change of the tool are mechanically applied and the turning moment during clamping of the tool is limited to a predetermined value.
