Abstract
An improved mechanical pencil, which is essentially characterized by being constituted by a general tubular body inside which the mine, charcoal or similar is housed, said body having at one of its ends a hole for the passage of that mine and a seat for receiving the base flanged by a clip formed by a bushing provided with longitudinal recesses and terminated with a frustoconical end, the body of said pencil being carrier, and as extension of said seat, of an externally threaded neck to which is threaded an axially perforated tip and provided in its bottom of an equally frustroconical surface that overlaps or fits over that of the gripper, a helical spring possibly being interposed between the bottom of said toe and the rim of the clip, producing the retention and release of the mine or similar with the threaded and unscrewed from said toe, which presses, in the first case, on the clamp, while in the second, it moves away from the same one helped by the action of the spring.
