The invention is based on a power tool with at least one handle () that comprises at least one grip part () that is firmly connected to a mounting part () via at least one elastic, vibration-damping element (), via which the grip part () is affixable to a housing (). It is proposed that the connection between the grip part () and the mounting part () is secured by means of the elastic element () via at least one movable retaining element ().

Hand machine tool comprising at least one handle

A tool-holding device for an insert tool () equipped with an at least essentially disk-shaped hub (), in particular for a hand-guided angle grinder () or a hand-guided circular saw, having a drive device () that includes a leaf spring unit () and is able to clamp the insert tool () in the axial direction (). The leaf spring unit () has at least one freely extending spring piece () that extends at least partially in the circumference direction ().

Tool-holding device

An insertion tool () for an angle grinder () that has a hub () with at least a first fastening means for fastening the hub () to a driving device () of the angle grinder (). The first fastening means if located on a partial circle () with a radius () of between 12 mm and 25 mm.

Insertion tool for an angle grinder

A tool-handling device for an insert tool() equipped with an at least essentially disk-shaped hub (), in particular for a hand guided angle grinder () or a hand-guided circular saw, having a drive shaft () and a drive device () equipped with at least one locking element() that is supported so that it is able to move in relation to a spring element () in order to fix the insert tool () in a form-locked manner in the circumference direction (). The drive shaft () has at least one form-locking element () formed onto it in a non-cutting manner in order to connect it in a form-locked manner in the circumference direction () to a drive torque-transmitting mechanism of the drive device ().

Tool-holding device for an insert tool with at least essentially disk-shaped hub

A hand power tool has housing, a motor arranged in the housing and having a drive shaft with two opposite ends, bearings each supporting one of the ends of the drive shaft in at least one component, an insert tool, a drive element through which the drive shaft is operatively connected with the insert tool, at least one of the bearings of the drive shaft being supported on the component over one part of its length in a radial direction through a sliding seat, and also being supported on the component over another part of its length in the radial direction through a synthetic plastic ring.

Hand power tool

An electric hand power tool has an on/off switch, an elongated switching key having a front end and a rear end and actuating the switch, a blocking lever carried by and projecting from the switching key to prevent or to allow turning on of the latter, the switching key being supported turnably, the switching key having a convex curvature starting substantially centrally and extending toward the rear end, the switching key carrying the blocking lever near the rear end, the blocking lever having an upper edge located under a tangent between the convex curvature and the rear end of the switching key.
