摘要： A screwing tool includes an elongate shaft which has, at each of its two ends, an output profile for insertion into a screwing tool insertion opening of a screw, and comprising a first insert and a second insert, which inserts: are each axially slidably arranged for conjoint rotation in a first and second cavity which are open toward an end face of the output profiles; each form, by means of their ends protruding from the cavity, an output profile; when in a position protruding from the cavity, are each supported, by means of a stop, on a counter-stop of the shaft; and can, by applying an axial force, be moved into the respective cavity against the restoring force of a spring element arranged in a chamber extending between the first cavity and the second cavity.

摘要： A screw driving tool including 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 torque-transmitting coupling being released when the torque transmission element leaves the depression in an edge-controlled manner against the force of the force accumulator, which can be adjusted by an adjustment device, when a limit torque is exceeded. In order to develop the tool in an advantageous manner in terms of application, a switchover element is proposed which can be moved from a release position into a blocking position and which allows the torque transmission element to leave the depression in the release position but blocks the torque transmission element in the blocking position.

摘要： 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.

摘要： 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.

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.

摘要： A screwdriver tool including a gear ratio arranged in a handle for multiplying a rotation angle transmitted from the hand to a blade protruding from the handle. A blocking element can be rotated from a release position, in which a first handle section can be rotated relative to a second handle section for the purpose of quick-action screwing, into a blocking position, in which a blocking element secures the blade to the handle in a rotationally fixed manner. The switching between the release position and the blocking position occurs by means of a push-button arranged in the tip of the handle, which is moved back into its starting position in a spring-loaded manner after being actuated.
