Estimating the term…
A screwdriving tool includes a gear head and a drive arm. The gear head forms a gear housing, in which a free wheel or ratchet gear having an output rotational axis is arranged. A front side of the gear head includes an output coupling, in the shape of a polygon. The drive arm can be pivoted about a pivot axis, which is substantially transverse to the output rotational axis, from a quick-action screwdriver position, in which the drive arm is in the output rotational axis, into a power-action screwdriver position, in which the drive arm extends substantially transversely to the output rotational axis and can be fixed in both pivot positions by detents. The detents can be moved from a detent position into a release position by means of an actuating member associated with the drive arm.
A screwdriving tool with a drive arm formed at one end as a handle portion and a freewheel gear arranged at the other end of the drive arm, and having a gear head which can be turned round at least through 90° into retained positions, characterized in that between the handle portion and the gear head, there is, on the drive arm, a freely rotatable and axially non-displaceable hand-action sleeve.
