Abstract: A hand-guided stroke-type saw includes a stroke rod and a saw-blade receiver that is supported by the stroke rod. The stroke rod defines a stroke axis extending axially through the stroke rod. The saw-blade receiver is configured to receive a saw blade and defines a saw-blade receiver axis that extends axially through the saw-blade receiver and is substantially parallel to the stroke axis such that the saw-blade receiver is offset radially from the stroke axis in a first direction opposite to a direction of advance.

Abstract: A tool chucking device, especially an oscillation tool chucking device, includes at least one chucking unit which has at least one pin-type chucking element for clamping a treatment tool in an axial direction and at least one grip head arranged on the chucking element. The tool chucking device further includes at least one movement conversion unit which is designed to displace at least the grip head at least substantially along the axial direction into at least one direction different from the axial direction depending on the movement of the chucking element.

Abstract: A tool chucking device, especially an oscillation tool chucking device, includes at least one chucking unit which has at least one chucking element for clamping a treatment tool in an axial direction and at least one control unit for actuating the chucking element. The tool chucking device further includes at least one conversion unit which is designed to modify a conversion ratio depending on at least one movement component of a control element of the control unit.

Abstract: A tool clamping device, in particular an oscillating tool clamping device, includes a clamping unit that has at least one clamping element configured to securely clamp a working tool in an axial direction and at least one clamping head arranged on the clamping element and configured to clamp the working tool at a free end of the clamping unit. The clamping unit further includes a guiding unit configured to guide at least one movement of the working tool along at least one direction of movement that deviates significantly from the axial direction in at least one operating state.

Abstract: A hand-guided semiautonomous jigsaw includes a tool receiver and an electronic control unit. The tool receiver is configured to receive a saw blade having a cutting edge for sawing along a predefined reference cutting line on an assigned workpiece. An electromechanical actuator is configured to swivel the tool receiver within a predefined angular range about a swivel axis coincident with a rotation axis of the saw blade in response to a signal from an assigned optoelectronic mechanism in order to automatically align the saw blade when sawing along the predefined reference cutting line. The electronic control unit is configured to compensate a parallel distance between the cutting edge and the rotation axis of the saw blade during sawing.

Abstract: A portable power tool actuating element for a jigsaw includes a bar-shaped handle that is intended to provide, at least indirectly, an on and off function for the power tool drive unit that drives at least one tool. A tool speed, in particular a tool stroke rate, is regulatable by the at least one portable power tool actuating element. A jigsaw includes the portable power tool actuating element. A method is provided for operating such a jigsaw.

Abstract: A tool chucking device, in particular an oscillation tool chucking device, includes a tool holder that has a first form locking element and a second form locking element. The form locking elements are provided at least for a form locking connection to a machining tool in a circumferential direction about a rotational machining axis. The form locking elements are mounted rotatably with respect to each other at least relative to a rotational axis that is oriented at least substantially parallel to the rotational machining axis and/or are mounted movably with respect to each other along at least one movement axis that is oriented at least substantially perpendicular relative to an axis that is parallel to the rotational machining axis.
