Abstract
A portable power tool has a drive unit for rotationally driving a tool receptacle about an axis of rotation, the drive unit having at least one drive motor and a shiftable transmission, which is arranged in a transmission housing with an at least partially sleeve-like clutch housing and a transmission cover fastened thereto. The tool includes a shifting element for shifting the shiftable transmission between at least two different gears, and a locking sleeve for locking the shifting element in at least a first and a second shifting position is arranged in the clutch housing. The shiftable transmission forms, at least in the first shifting position, a cross-sectional plane perpendicular to the axis of rotation in which the locking sleeve is arranged at least regionally between the transmission cover and the shifting element and the shifting element is arranged at least regionally between the locking sleeve and the clutch housing.
