A device in which, within a rotating holster (1), an arranged body (8) can be bought into a rotation movement relative to the holster from a body (9) surrounding the holster. The inner body's (8) outer surface (5) and the outer body's (9) inner surface (6) form circular cylindrical guide surfaces. These surfaces (5, 6) are mutually parallel but eccentrically placed relative to the holster's (1) rotational axle and the inner body (8) is eccentrically deployed relative to its guide surface (5). The holster (1) is equipped with a number of openings (3), in which radially movable separator units (4) are arranged. This arrangement, which preferably consists of spherical objects (4), is designed to be deployed in the holster's rotational movement and during rotation works with both guide surfaces (5, 6). The device can be used to advantage in connection with a screw extractor with an inner reverse thread for the screw. The reverse thread is thereby connected with the inner body.<IMAGE> |
