An auxiliary handle device, in particular for a hand-held power tool, has an auxiliary handle and a damping unit with at least one absorber mass element. The absorber mass element is designed in the shape of a sleeve along a main extension direction of the auxiliary handle device.

Auxiliary handle device

In an electric hand machine tool, particularly an angle grinding machine, for the purpose of ergonomic handling the handle, together with the switch bar, is designed to be rotatable, relative to the tool mounting on the gear head (11). For the rapid, problem-free changing of the position of the handle relative to the tool mounting, the handle (12) can be locked against rotation on the motor casing, containing the electric drive, in at least two turned positions by a manually operable locking device, and can be clamped on the motor casing by a manually operable clamp device. In a preferred embodiment the locking device (40) and clamp device are coupled together by constraint and are operated simultaneously by means of a single tightening lever.
