A hand-held power tool, particularly a hammer drill, includes a work spindle, a hand-held power tool housing and an intermediate shaft, which is arranged in parallel to the work spindle and mounted in an axially displaceable manner for changing the operational mode, and a tooth sleeve, which is provided to transfer a torque to the intermediate shaft. The tooth sleeve is fixed in the axial direction by means of the hand-held power tool housing.

Hand-held power tool

A portable power tool has a housing, a rotating sleeve provided for rotatably driving a tool and a rotatably supported in the housing by at least one bearing, a driving gear-wheel installed on the rotating sleeve in a freely rotating manner and drivable by a motor, a safety clutch that couples the driving gear-wheel with the rotating sleeve in a rotation-proof manner, the safety clutch having two clutch members that are slippable, with one of the clutch members being assigned to the driving gear-wheel and the other clutch member being assigned to the rotating sleeve in both cases in a rotation-proof manner, and with a coupling sleeve providing a force against which the clutch members are slippable when a limit torque is exceeded, the bearing being seated on the rotating sleeve in an axially displaceable manner and loaded by the coupling sleeve of the safety clutch against an axial stop of the rotating sleeve.

Portable power tool, in particular a drilling hammer and/or impact hammer

A portable power drill or hammer drill having a housing () which consists in particular of half shells () and accommodates a manual gearbox (), wherein a shift element () that can be rotated by hand converts its rotary movement into a shift movement, can be produced cost-effectively and can be easily operated, without lubricant escaping from the housing (), by the shift element () consisting of a shell-like handle part () which can be joined together with a further, shell-like shift part () in a sealing manner from outside and inside relative to a housing shell ().

Portable power drill with gearbox

A tool fitting that is provided to accommodate a rotary hammer bit and/or a chisel bit () and an adapter (). The tool fitting has centering elements () for at least reducing the mobility of the adapter () when mounted in comparison to the mobility of the rotary hammer bit and/or chisel bit () when mounted.

Tool fitting, adapter and system with a tool fitting and an adapter

The present invention relates to a power tool, including at least a first and a second housing part, many components, in particular electric motor components or electrical components, and one fastening element for fastening the many components to the first housing part in such a way that the components are fixed between an inside of the first housing part and the fastening element.
