ABSTRACT:
A portable power tool has, in order to drive a tool (12), a hollow spindle (14) to which the tool (12) can be fastened between two flanges (16, 18). The outer flange (16) is configured at the end of a clamping bolt (22) that is inserted through a central opening (17) of the tool (12) and projects at its other end out of the housing (42). The clamping bolt (22) can be non-rotatably secured at this end by means of a retaining element (20). For actuation, a clamping device (24) is provided, which can be moved, against the force of spring elements (26), between a clamped position in which the retaining element (20) is acted upon axially to clamp the tool (12), and a released position in which the tool is disengaged for manual changing. The spring elements (26) are arranged between an axial fixed stop (28) and an axially displaceable stop (FIG. 1).
