Abstract: In a rotary tool (1) for tightening or releasing a screw connection, in which the rotary tool (1) has a freewheel mechanism (29), it is provided that the rotary tool (1) is configured to be electrically isolated in a partial region between a tool attachment point (6) and the freewheel mechanism (29).

Abstract: The invention relates to a screwing tool for transmitting a set torque. Two torque-limiting arrangements (5, 7) are provided that are biased by the same spring element (9).

Abstract: A screwing tool includes a head, which has a fixed jaw and a movable jaw and which is fastened to a handle so as to be pivotable about a pivot axis against a restoring force from a small distance position of the two jaws into a large distance position of the two jaws. In order to be able to touch live parts by means of a screwing tool of this type, the handle has an insulating casing and an actuating element is provided, which can be displaced relative with respect to the handle and which, during its displacement, displaces the head from the small distance position into the large distance position.

Abstract: A screw driving tool includes a torque output element which defines an axis and is mounted in a housing, a torque transmission section with a plurality of depressions, and a torque transmission element, which is pretensioned by the force of a force accumulator and engages into at least one of the depressions, for coupling the torque transmission section to the housing so as to transmit a torque. The coupling is released when the torque transmission element leaves the depression in an edge-controlled manner against the force of the force accumulator, which is adjustable by an adjustment device, when a limit torque is exceeded. A switchover element is movable from a release position into a blocking position and allows the torque transmission element to leave the depression in the release position but blocks the torque transmission element in the blocking position.

Abstract: A screwing tool, including an elongate handle which, at each of the two ends thereof, bears a head pivotable about a pivot axis and having two torque transmission flanks in each case and has a force application flank for introducing a force in order to produce a torque on the head remote from the relevant force application flank, wherein, in a pivoting end position of the head, in which a stop of the head lies against a counter stop of the handle, a narrow side of the head functionally directed away from the stop forms an extension of the force application flank. The second head forms an extension of the force application flank and can be used as a hand grip.

Abstract: Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.

Abstract: Stripping pliers have two outer clamping jaws, two inner cutting jaws and two handle parts, wherein, in the course of pressing together the handle parts, the cutting jaws can be displaced from a starting position into an end position by a pull rod against the force of a spring acting on the pull rod. The pull rod is traversed by a pull pin which can move in a slot. In order to configure the stripping pliers such that they are further improved in a manner which is advantageous for handling, the pull rod has, at its handle-side end, a displacement part which is fastened to the pull rod and which is displaceable against the force of the spring relative to the pull rod, to free the pull rod from a handle-side mounting.

Abstract: Gripper jaws for an insulation stripper have a gripping surface and an attachment extension with ribs which run transversely to a longitudinal direction of a cable to be gripped when the gripping surfaces are fitted, and have groove-like recesses corresponding to the ribs and running between the latter. When the gripper jaws are fitted, the ribs can enter into the recesses of the opposing gripper jaw in accordance with the thickness of the cable to be gripped. Blades for an insulation stripper have, on their free ends that run into a blade tip with an acute angle in cross-section, a contour line which has a depression, when seen from a side view in which the contour line forms the termination line of the blade.

Abstract: A pair of crimping pliers for crimping, in particular for crimp joining, workpieces, has two oppositely arranged pressing jaws and two pliers jaws, wherein one pliers jaw is stationary and the associated pressing jaw is fastened to this stationary pliers jaw by means of a spring-loadable holder part. The holder part is fixedly connected at its end farthest from the pressing jaw to the pliers jaw. Between the stationary connection and the end of the holder part closest to the first pressing jaw, a stop connection is formed between the stationary pliers jaw and the holder part and comes into effect when a predetermined pressing force is exceeded.

Abstract: An insulation-stripping tool designed as a hand tool for stripping insulation from a cable has a first insulation-stripping cutter for stripping the insulation transversely to a longitudinal direction of the cable and a second insulation-stripping cutter for stripping the insulation in the longitudinal direction of the cable.

Abstract: A torque-limiting device having two torque transfer bodies, which, as a consequence of oblique flank contact during relative rotation about an axis, can be moved relative to each other in the direction of the axis against the restoring force of a spring element, which is supported on a shoulder of an abutment, the position of which shoulder is set during calibration of a limiting torque. The torque-limiting device is calibrated by applying a predefined force to the spring element. The resulting spring length defines the axial position of the shoulder of the abutment, which axial position is irreversibly fixed.

Abstract: Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.
