ABSTRACT:
A tool includes an adapter for coupling to a rotary element such as a screwing/unscrewing socket. The adapter is equipped with a mechanism for locking the coupling. The lock mechanism is unlockable and normally locked. The tool further includes a main drive member for rotating the adapter, and the main drive member includes, for example, a ball-type universal joint. The lock mechanism is unlocked simply by a displacement of the main drive member towards the distal end of the adapter.
