Quick clamping device for a portable power tool having at least one rotatably drivable output shaft, in particular an angle grinder

A quick clamping device for a portable power tool having at least one output shaft configured to be driven in rotation, the quick clamping device comprising:

• at least one clamping unit including at least one movably mounted clamping element configured to exert a clamping force on an insert tool unit in a clamping position of the at least one movably mounted clamping element, the at least one clamping unit configured for fixing the insert tool unit to the at least one output shaft without use of tools;
• at least one operator control unit configured to move the at least one movably mounted clamping element into the clamping position and/or into a release position of the at least one movably mounted clamping element;
• and
• at least one decoupling unit configured to decouple the at least one operator control unit from the at least one clamping unit in a manner dependent on a rotational speed of the at least one output shaft,
• wherein, in the release position, the insert tool unit is removable from the at least one clamping unit.
