Claim:
1. An electromechanical lock, comprising: an electronic circuit configured to read data from an external source, and match the data against a predetermined criterion; a support configured to move by electric power to an open position provided that the data matches the predetermined criterion; a locking mechanism configured to hold the lock, when engaged, in a locked state, and, when disengaged, in a mechanically openable state; a lever coupled with the locking mechanism configured to receive mechanical power from a user to store mechanical energy to a return spring, and to output the mechanical power to mechanically disengage the locking mechanism from a locked state provided that the support is in the open position; and a return mechanism for the support comprising a reset spring whose end is configured to, during the reception of the mechanical power from the user, move past the support with mechanical power outputted by the lever, and, finally, force the support with the mechanical energy outputted by the return spring to a locked position.
