"AUTOMATIC PENCIL OF A SINGLE MINE" characterized by the fact that the mine emerges from the interior of the handle and is hidden therein, driven by its own weight, when the pencil is placed in the vertical position, with the point directed downwards or upward, as desired to protrude or hide, making the retention of the mine, using a clamp -1-, attached to a tube that is fixed inside the handle -5-, which is composed of three or more jagged mouths on its inner surface that approach or separate, changing the diameter of the jaw, in line with the thickness of the mine they imprison, by virtue of a moving part -2-, which wraps the said jaw, which when advancing driven by a spiral spring -5-, housed inside an inner sleeve -4-, reduces the diameter of the jaw -1- to a limit fixed by the conical shape that has the outer surface of said jaw.
