<p>The drive tool has two principal parts. It has an end piece (5) which couples to the rotating socket (2). The end piece includes a fastening mechanism (6) which can be activated to release the coupling and is normally in the fastened position. A drive assembly (7) is provided to rotate the end piece. There is a tolerance of movement (J) between the end piece and drive assembly. This permits a relative displacement along an axis X-X. The drive assembly is adapted to release the fastening mechanism under the simple action of displacing the drive assembly the furthest distance away from the end stop.</p> |
