A tool device including a stationary part and a shifting part which has a tool and which can be shifted relative to the stationary part and in the process carries out a shifting movement in order to set a position of the tool relative to the stationary part, and a guide means which is designed to guide the shifting part relative to the stationary part during the shifting movement. The guide means includes a guide structure that defines a movement path, and a guide part that rests on a guide contour of the guide structure and that can be moved along the movement path in order to carry out the shifting movement. The tool device includes a pressing mechanism which has a spring element which is designed to press the guide part against the guide structure, in order to reduce or eliminate play between the guide part and the guide.

A hand-held milling device for producing a recess in a workpiece that has a bearing means having a bearing structure, which includes a first structure portion and a second structure portion for simultaneously bearing against the workpiece in a stationary manner during the production of the recess, the first structure portion defining a first bearing plane and the second structure portion defining a second bearing plane, and the second structure portion being pivotably mounted relative to the first structure portion. The milling device includes: an electrical positioning device which is designed to displace the milling tool along at least two positioning degrees of freedom relative to the bearing structure; and an electronic control unit which is designed to control the electrical positioning device according to movement information so that the electrical positioning device displaces the milling tool in a movement sequence along the at least two positioning degrees of freedom.

A mobile hand-held sawing machine having: a sawing assembly ( 11 ), which has a sawing tool holder ( 14 ) for a sawing tool ( 15 ) and a saw drive motor ( 12 ) for driving the sawing tool holder ( 14 ); and a guide device ( 17 ), which has a guide body ( 18 ) having a guide face ( 19 ), extending along a longitudinal axis (L), for guiding the hand-held sawing machine ( 10 ) in a working direction (AR) on a workpiece (W); the hand-held sawing machine ( 10 ) having a pre-cutting assembly ( 31 ), which is arranged on the guide device ( 17 ) in front of the sawing assembly ( 11 ) in relation to the working direction (AR) in a longitudinal position in relation to the longitudinal axis (L) and has a pre-cutter tool holder ( 34 ) for a pre-cutting tool ( 35 ) and a pre-cutter drive ( 32 A) for driving the pre-cutter tool holder ( 34 ).

A holding element ( 60 ) for a device for supporting and/or guiding a machine tool ( 20 ) or a workpiece (W), wherein the device includes a contact body ( 40 ) having a contact surface ( 42 ) for contact on a work surface (H) of a workpiece (W) or a wall. It is provided that the holding element ( 60 ) includes an adhesive means ( 70 ) for adhesion to the work surface (H) and a fastening means for a releasable hold on the contact body ( 40 ), wherein the fastening means includes at least one formfitting contour ( 90 ) for formfitting hold on a holding element receptacle ( 55 ) of the contact body ( 40 ).

A wearing device, which is designed as an exoskeleton and/or includes a tool, for wearing on the human body, including a shoulder strap with a shoulder strap resting section for resting on a shoulder of a user. The shoulder strap resting section has a target bending structure extending in the longitudinal direction of the shoulder strap for reducing the bending stiffness of the shoulder strap resting section in a bending direction transverse to the longitudinal direction of the shoulder strap, so that the shoulder strap resting section, in a state resting on the user's shoulder, can be bent in the bending direction by an elevation movement of the user's arm and a resulting formation of a shoulder hollow of the user, in order to assume a bent shape corresponding to the shoulder hollow and thus rest with its surface area against the user in the shoulder hollow.

A connector for coupling a particle outlet of a handheld machine tool to a particle receiving device is described. The connector has a tube-shaped inlet portion extending along an inlet axis and a tube-shaped outlet portion extending along an outlet axis. The tube-shaped outlet portion is for coupling to the particle receiving device. The inlet portion has a body section and an engagement section. The engagement section is resiliently coupled to the body section. The engagement section has an engagement geometry for mating with an engagement counter-geometry on the particle outlet, such that a positive locking effective along a circumferential direction is provided between the engagement geometry and the engagement counter-geometry. Moreover, a lock is coupled to the inlet portion. The lock is for selectively blocking a movement of the engagement section relative to the body section. Moreover, a handheld machine tool, a handheld machine tool assembly, and a method for operating a handheld machine tool assembly are presented.

A blocking element for an emergency brake unit of a sawing device has a circular disc-shaped saw blade. The blocking element has a bearing portion, via which the blocking element is configured to be mounted on the sawing device, a head portion which is designed to engage into the saw blade selectively for braking purposes, and a deformation portion which is located between the bearing portion and the head portion and/or connects the bearing portion and the head portion to one another and which is arcuate and designed to be plastically shortened to brake the saw blade in an arc circumferential direction. A sawing device has a circular disc-shaped saw blade and an emergency brake unit. The emergency brake unit has such a blocking element which is mounted on the sawing device such that it can engage selectively into the saw blade to brake the saw blade.

A sawing device has a frame, a circular disc-shaped saw blade mounted rotatably with respect to the frame, and an emergency brake unit. The emergency brake unit has a blocking element, an actuator unit and a control unit. The blocking element has a bearing portion and a head portion designed to engage into the saw blade selectively for braking. The actuator unit is coupled to the blocking element in a normal blocking element position, such that the blocking element engages with the saw blade selectively with the actuator unit. The blocking element can be selectively disassembled from the frame separately from the actuator unit and/or from the control unit. A triggered emergency brake unit of a sawing device ready for operation may be provided. In this regard, a blocking element is disassembled separately from the actuator unit and/or separately from the control unit and an unused blocking element is mounted.
