A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

Hand-held power tool

A system includes first and second power tools that each have a percussion mechanism, a motor, and a transmission. The transmission includes a striking mechanism and is configured to transfer a driving motion of the motor to an insert tool held in a tool holder. The transmission has a guide tube that is identical in some regions along a working axis and accommodates a striker. The guide tube is rotatably coupled to the motor by a first transmission unit. The striker is driven to linearly oscillate by a piston of a second transmission unit. A ratio between a diameter of the tool holder and a diameter of the guide tube is 1.8 times greater in the first power tool than in the second power tool. A striking energy of the second power tool is mechanically reduced compared to a striking energy of the first power tool.

A hand-held power tool device, in particular a hammer drill and/or chisel hammer device, includes at least one operating element and at least one locking unit. The at least one locking unit includes at least one locking element and at least one controllable actuator element. The at least one locking element can be moved from at least one storage position into at least one locking position, and vice versa, and locks the operating element in at least one operating state in the locking position. The at least one controllable actuator element influences motion of the locking element.

Hand-held power tool device

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

Hammer drill

The invention relates to a hand tool machine (), in particular a drilling and/or percussion hammer, with a housing () and a vibration-damped handle () elastically supported relative to the housing () with two essentially parallel legs () and a coupling element (or) between each leg (or) and the housing () that is pin-jointed to the leg (or) and the housing (). The coupling elements () are connected to each other by a connector () that synchronizes the movements of the coupling elements ().

Hand-held power tool with a vibration-damped handle

The invention is a striking mechanism for a handheld power tools in particular electric hammer. A piston is arranged in an axially bidirectionally movable manner in a guide tube. A striker is provided which acts on a striking pin and which is held in a movable manner in the guide tube. A compression space is delimited by the piston and the striker such that an air cushion is enclosed therein. It is proposed that at least one spring element is provided between the striker and the striking pin.

Striking mechanism for a handheld power tool

The invention is based on a portable power tool having a vibration-damped handle () which has two legs () running in the longitudinal direction () of the portable power tool and which is motionally coupled to its housing (), wherein at least one lever () oriented transversely to the longitudinal direction () is coupled to each of the two legs () at an articulation point (), and wherein the levers () are coupled to a joint region () lying between the two legs () of the handle (). It is proposed that each lever () have a bearing point () between the joint region () and the respective articulation point ().

Handheld power tool with vibration-damped handle

The invention relates to an additional hand grip () for a hand machine tool, comprising a clamp () for clamping the additional hand grip () to a part of the hand machine tool, a handlebar () for gripping and holding of the additional hand grip (), and a pivot joint () that can be blocked, arranged between the clamp () and the handlebar (). The pivot joint () can be blocked with an eccentric tension lever (), which is formed by a pivotable part () of the handlebar ().
