Abstract
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.
Claims12
A screwing tool comprising:
- an elongate shaft (1),
- an output profile (2, 12) for insertion into a screwing tool insertion opening (23) of a screw (31),
- a first insert (19) and a second insert (25), wherein said inserts (19, 25) are respectively arranged in a first cavity (4) and a second cavity (14), each of the first and second cavities opening toward an end face (3) of the output profiles (2, 12),
- wherein each of the first and second inserts in a rotationally fixed and axially displaceable manner, respectively form an output profile (21, 27) with their ends protruding out of the cavities (4, 14), and are respectively supported with a stop on a counter stop of the shaft (1) in a position, in which the first and second inserts protrude out of the cavities, and can be displaced into the respective cavity (4, 14) against the restoring force of a spring element (10), which is arranged in a chamber (7, 8) extending between the first cavity (4) in the second cavity (14), by exerting an axial force, wherein the first cavity (4) and the second cavity (14) respectively transform into the chamber (7, 8), which has a greater internal cross-sectional area than the adjoining cavity (4, 14), such that a first step (15) and a second step (15′) are formed, wherein the first step (15) forms the counter stop, on which the stop of the first insert (19) is supported, and the second step (15′) forms the counter stop of the second insert (25), on which the stop (11) of the second insert (25), which is configured to be elastically deformed radially inward, is supported.
