Abstract
A quick-clamping device for a portable machine tool, in particular for an angle grinder, includes at least one clamping unit and at least one control unit. The clamping unit includes at least one clamping element mounted movably with respect to a movement axis of the clamping unit so that the clamping unit is configured for tool-free fixing of an insertion tool unit to an output shaft of the portable machine tool. The control unit includes at least one movably mounted control element configured to actuate the clamping unit. The control element is mounted at least in a translatory and/or pivotable manner and is configured to transfer the clamping unit from a clamping position into a release position according to a movement of the control element.
