The tool can be locked in the cavity (2) by a holding element (4) which is assigned to the cavity wall in order to prevent the tool from being withdrawn from the cavity (2). The holding element (4) can be deactivated by displacing an actuating member in a form of an actuating sleeve (5). The tool (1) rests backwards against the cavity (2). The tool (1) can be displaced from the resting position in the direction of the opening of the cavity (2) by actuating the actuating sleeve (5). In order to facilitate removal of the bit, the chuck also comprises components (15, 16, 17) for releasing the face (1) of the bit, and a magnet (9) which retains the bit in the cavity from the resting position.

Abstract: The invention relates to a tool, especially a screwing tool having a handle with a chuck, and a blade, especially a screwdriver blade, that can be inserted into an insertion opening of the chuck. The blade inserted into the insertion opening is held by a detent of the chuck, said detent being displaced from a detent position to a release position by actuating a trigger. The inventive tool is characterized in that the detent comprises a detent projection which is located on a spring arm that extends in the axial direction of the insertion opening and on the periphery thereof. Said spring arm is displaced by a control element of the trigger that can be displaced in the axial direction from the detent position to the release position. The insertion opening is configured by an insertion cylinder located in a cavity of the handle. The insertion cylinder is produced from plastic and the spring arm is associated with the insertion cylinder in order to form a single part consisting of the same material.

Abstract: Screwing tool (1) having a grip (2) and a shank (3), which is received removably in a cavity (4) open toward an end of the grip (2) and which at its free end has an actuating portion (5). The shank (3) is retained in a position of use such that it is fixed in terms of rotation on the grip, to avoid sliding in the axial direction, by a retaining element (14) associated with the grip (2). The retaining element (14) can be displaced into a removal position by displacement of an actuating member (6) in order for the shank to be removed from the grip (2). In a storage position, a large part of the shank (3) is located in the cavity (4), where it is held by a holding element (H). The holding element (H) is releasable, so that part of the shank (3) can be moved out.

Abstract: A chuck (1) for tools, especially screwdriver bits with a polygonal section (2), has a polygonal cavity (3) for the insertion of the polygonal section (2). A wall (4) of the polygonal cavity (3) has a window (5) in which is disposed a pressure-piece (6) which can be displaced in the insertion direction (E) and which, in order to secure the inserted polygonal section (2) against being drawn out, is forced against the polygonal section (2), in a direction transverse to the insertion direction (E), by a sloping inner wall (9) of an actuating element. The actuating element is outside the window and is retained in a clamping position by a restoring spring (10), and, in a release position of the actuating element (7), moves aside out of the polygonal cavity (3) in order for the polygonal section (2) to be drawn out.
