Abstract

L'invention concerne un dispositif d'enfoncement, comprenant un boîtier (1) guidé à la main dans lequel est logé un élément de transmission d'énergie (2) servant à transmettre de l'énergie à un élément de fixation, et un mécanisme d'entraînement (7) servant à faire avancer l'élément de transmission d'énergie (2). Le mécanisme d'entraînement (7) comprend un accumulateur à ressort (8) équipé d'au moins un élément à ressort (12) déformable élastiquement qui s'appuie sur une butée (3, 3b, 3c, 21) de l'accumulateur à ressort (8). La position de la butée (3, 3b, 3c, 21) peut être modifiée de manière réglable au moyen d'un organe de réglage (3b, 18, 21) afin d'ajuster l'absorption d'énergie par l'élément à ressort (12) pour une course prédéfinie.
