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.
Claims27
Tool for driving a rotary element, the tool comprising two main members, namely:
- an adapter for coupling to the rotary element, said adapter having an axis, a distal end and a proximal end and being equipped with a lock mechanism for locking and unlocking the coupling of said adapter to the rotary element, said lock mechanism being normally locked;
- and
- a main drive member for rotating the adapter;
- wherein:
- between the adapter and the main drive member there is play allowing a relative displacement that has a component along the axis of the adapter, and
- the main drive member is designed to unlock the lock mechanism under the effect of said relative displacement of said main drive member with respect to the adapter towards the distal end of the adapter.
