A holding device for hand machine tools, in particular a drill and/or a chipping hammer holding device, includes a hammer tube and at least one blocking body, which, when installed, connects the hammer tube to at least one additional holding component. The blocking body is provided with at least one blocking surface that is curved around at least one load tipping axis.

Holding device for hand machine tools, in particular holding device for a drill and/or chipping hammer

The invention relates to a hand machine tool (), particularly a percussion drill and/or percussion hammer, comprising a housing () having two parallel appendages (), a hollow, U-shaped, rounded handle () with a yoke () and two parallel legs (), said handle being movably supported on springs in relation to the housing () for the purpose of damping vibration. The appendages () of the housing () extend into both hollow legs () of the rounded handle (). The invention also comprises two coupling elements () situated in the hollow yoke () of the rounded handle () which serve to synchronize the movements of both legs (). The external end faces of the coupling elements () are flexibly connected to the appendages (). The coupling elements () are connected on the other end faces thereof to the rounded handle (), and cross each other, and are flexibly connected to each other at the crossing point.

Hand-held power tool with a vibration-damped rounded handle

A hand-operated power tool has a housing with a drive mechanism for driving a tool, a tool receptacle for receiving a tool, a handle assembly for grasping and handling located in a rear region which is remote from the tool receptacle and engaging the housing, wherein the handle assembly is vibration-damped with respect to the housing with components contained in the housing, at least and substantially in an axial direction.

Power tool with a rotating and/or hammering drive mechanism

A hand power tool has at least one safety coupling arranged in a drive train, the safety coupling having at least two coupling elements for transmitting a torque around a rotary axis, at least one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, a guiding element, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage, and the arresting element unlatching and keeping in contact with a surface toward which the arresting element is urged by the spring in response to exceeding of predetermined torque.
