Abstract
Screwing tool (1) with a handle (2), tool holding fixture (3) and ratchet (4), in which the ratchet has a pivotally mounted ratchet element (6) which has several catch cams (5), and a first stop bolt (7), in which stop bolt (7) can be engaged with ratchet element (6) by displacement in an axial direction (9) defined by axis of rotation (8), such that handle (2) can turn relative to the tool holding fixture (3) in a first direction of rotation and can be locked by form-fit in the opposite second direction of rotation. Furthermore, the ratchet (4) has a second stop bolt (7) which can be engaged with ratchet element (6) by displacement in the axial direction (9) such that the handle (2) can turn relative to the tool holding fixture (3) in a second direction of rotation and can be locked by form-fit in the first direction of rotation, and a switching device (10) is associated with the two stop bolts (7) to switch the direction of rotation in which the locking action occurs by selectively disengaging the stop bolts (7).
