An autoinjector having a reservoir (); a piston (); a needle (); a driver module having a body (); a piston rod () movable between rest position and injection positions; an injection spring (); and a lock that blocks the piston rod in its rest position. The lock ha a thread () connected to the piston rod and to a toothed winder wheel (), a locking member () co-operating with a tooth () of the toothed winder wheel, the locking member () movable between a blocking position preventing the winder wheel from turning in the direction of actuation force (Fa) exerted by the injection spring, and an actuated position allowing turning of the winder wheel. The autoinjector includes a re-cocking mechanism () for rewinding the thread on the winder wheel by turning the winder wheel in the opposite direction to its direction during the injection stage.
