An improved clutch mechanism for electromechanical lock cylinders is disclosed. The aim of the invention is to improve the performance of the clutch mechanism and to increase the battery life of the motor which is included in the electromechanical lock cylinder. The improved clutch mechanism comprises an electromagnetic motor (2) with a threaded spindle (3) on its shaft; and a movable cart (4), which comprises a resilient device determined by two front springs (26) joined together at one of their ends by a common transverse portion (26′) engaged in a valley of the spindle (3) thread, which moves the movable cart (4) by means of the common transverse portion (26′) between a disengaged position and an engaged position, such that in both positions the common transverse portion (26′) carries out a continuous thrust on the spindle (3). |
