Abstract

The invention relates to a clamping device for a hand-held power tool, comprising at least one clamping unit (12; 12') for mounting a machining tool (14; 14') in an axial direction (16; 16') and at least one operating unit (18; 18') for actuating the clamping unit (12; 12'). According to the invention, the operating unit (18; 18') comprises at least one cam mechanism (26; 26') which is designed to move at least one coupling element (28, 30; 28') of the operating unit (18; 18') in at least in one component perpendicular to the axial direction (16; 16').
