Abstract
Rotary drive for driving a tool fitting of a hand-held power tool, in particular of a combination hammer or hammer drill, wherein the rotary drive is configured, with respect to a working axis of the tool fitting, to convert a thrust input movement into a rotary output movement, wherein the rotary drive is in the form of a slotted-link mechanism with a freewheel-mounted track body and a ball cage arranged coaxially with the track body, wherein, when the ball cage is subjected to the thrust input movement, at least one ball of the ball cage slides along in an endless track contour formed on an outer surface of the track body and thus brings about a rotation of the freewheel-mounted track body.
