Abstract
A hand-held power jigsaw includes a clamping device which has an insertion slot (26) for a shaft (153) of the tool and has a transverse aperture (27) extending transversely to the insertion slot (26) and opening out into it. A clamping element (19) for clamping the shaft (153) can slide in the transverse aperture (27) and travels into the insertion slot (26) at one end and protrudes out from the transverse aperture (27) at the other end. A centering piece (18) has a rotatable clamping sleeve (20) equipped with a clamping curve (28) that slides the clamping element (19), equipped with a clamping spring, which engages the clamping sleeve (20) and rotates the clamping sleeve (20). The centering piece (18) has two transverse apertures (27) and in which two clamping elements (19) are supported opposite each other in a movable fashion.
