ABSTRACT:
The invention is based on an electric power tool having at least one drive unit and a gear unit, where the gear unit is a drive element for applying force to a piston unit. It is proposed that the drive element and the piston unit be arranged in an axially parallel manner. At least a region of the drive element overlaps axially with a longitudinal portion of the piston unit. The drive unit is arranged approximately centrally in an axial extension of the piston unit and the longitudinal axis of the drive unit is arranged transversely to the piston longitudinal axis.
