Abstract
Device for blocking the column in rotating drills, characterized in that the support on which the column is guided suitably guided is crowned by an open clamp, which surrounds its upper part and whose corresponding ends are topped on respective lugs between which it is mounted a flat bar, provided with holes that correspond, with others, to the lugs and in which, axes provided with eccentrics are topped, which are housed in the holes of the bar, being in one of these, with one more head long in which the corresponding control lever engages which, when acting, causes the rotation of the eccentrics and the consequent tensile stress on the plate that makes it approach or open to the ends of the clamp according to the direction of rotation of said clamp lever locking or releasing the column.
