摘要

An improved conical head, particularly for fastening tools in machine tools, intended, by means of its external conical surface, to cooperate with a correspondingly shaped conical inner surface of a mounting part, characterized by means of adjustment at the end top of the conical head, concentrically therewith and intended to support at least one elastic washer, whose circumference corresponds essentially, or is somewhat greater than the circumference of said upper end, which is designed with an external chamfered portion that forms an angle with respect to a plane perpendicular to the longitudinal axis of the conical head, which is greater than the angle formed by an unloaded washer and said plane, and by a tubular member surrounding the adjustment means and resting on the washer (highest part) to exert pressure on it when it is held under pressure at its opposite end.
