    摘要： A tool attachment for mounting on a hand-held machine tool provided with a tool holder, the tool attachment having an output shaft and a base body at whose outer circumference a locking sleeve is disposed in a manner allowing it to rotate to release at least one assigned locking element; at the outer circumference of the base body, an anti-rotation unit is formed for the twist-proof mounting of the base body on a fastening unit assigned to the hand-held machine tool; on the anti-rotation unit and at an inner circumference of the fastening unit, complementary geometrical forms are provided which are configured to mesh with each other for the releasable, twist-proof mounting of the base body on the fastening unit.

    摘要： A hand power tool is described having a drive arrangement providing on initial energization of the unit automatic gripping of a tool. The drive arrangement includes a fluid pump which is driven by the motor of the tool when it is first started. The pump delivers fluid pressure to a chamber within the tool chuck and drives a piston therein which, in turn, drives the jaws of the chuck into clamping engagement with the tool piece shank. The jaws of the chuck are meshed with one another in a manner assuring that they uniformly move radially inward to grip the shank and align the tool with the rotational axis of the chuck.
