Abstract
Screwing device which incorporates a screw charger. The device comprises a tube which encloses axially aligned screws and which is capable of being made integral with a maneuvering shaft. The tube comprises, at its free end, rings for blocking the head of a screw and allowing only the threaded part of the screw to protrude. The screw is brought into this position with the aid of an axial thrust shaft which can be maneuvered by the user. For rotationally blocking the screw in the screwing position, the tube comprises at least two longitudinal slots which confer on the free end a certain transverse elasticity permitting a screw to be brought into the screwing position, and ensure that the screw is not driven in rotation and is released when the limit torque is reached.
Claims4
Screwing device which comprises a tube (2) which encloses axially aligned screws and a maneuvering shaft, said tube having a free end with means for blocking the head of a screw and allowing only a threaded part of said screw to protrude in a screwing position and for blocking the screw against rearward and forward displacement, axial thrust means for bringing said screw (5) into the screwing position and which can be maneuvered by the user;
- means for rotationally blocking the screw in the screwing position;
- said tube also comprising, at said free end, at least two longitudinal slots which confer on said free end transverse elasticity for preventing the screw brought into the screwing position from being driven in rotation when a limit torque is reached.
