Abstract
A quick clamping device for a portable power tool, in particular an angle grinder, includes an output shaft that is configured to be driven in rotation and at least one clamping unit that is configured to fix an application tool unit to the output shaft without tools. The clamping unit has at least one movably mounted clamping element configured to apply a clamping force to the application tool unit in a clamping position of the clamping element. The clamping element is formed by a positive-locking element that is movable transversely to an axis of rotation of the output shaft and is configured to engage behind at least a subregion of the application tool unit in a positive-locking manner so as to secure the application tool unit.
