Abstract

The invention relates to a drive mandrel for a drilling stem. The mandrel comprises a tubular element traversed by the drilling stem and having openings for the passage of jaws urged against the stem under the action of wedges. The wedges are spring biased against the jaws, and repelled from said jaws by hydraulic thrust. The wedges are mounted on an axially adjustable flange.
