Abstract
Pencil double mine, which is essentially characterized by being constituted by a tubular body, equipped with a guide nozzle to exit the mines, inside which moves the driving element thereof, consisting of a cable that presents in its ends, respective clamping devices thereof and whose cable exits to the outside by recesses made in the opposite end of the tubular body and bends and rests on a pulley mounted in said recesses, forming a protruding ring whose rotation in one or the other direction drives one or another mine towards the tip of the pen, for its use.
