The invention relates to a screw driver with integrated screw holder, comprising A) a shaft (2) that can be linked with drive means and that has a cross-sectional area (9) that is orthogonal to the longitudinal axis (3). Said shaft has a front shaft segment (5) that can be inserted into a receiver adapted to receive a screw driver on a screw head and in which at least one longitudinal recess (7) having a longitudinal axis (8) that is oriented at an angle to the longitudinal axis (3) is provided. The screw driver further comprises B) at least one spring element (6) that is inserted into the at least one recess (7) and that projects beyond the cross-sectional area (9) of the front shaft segment (5) at an angle to the longitudinal axis (3). The screw driver is further characterized in that C) the spring element (6), on its part projecting beyond the cross-sectional area (9) at an angle to the longitudinal axis (8) of the recess (7), is elastically deformable.
L'invention concerne un tournevis muni d'un porte-vis, qui comprend A) une tige (2) raccordable à des éléments d'entraînement, qui présente un axe longitudinal (3), une surface de section transversale (9) orthogonale à l'axe longitudinal (3) et un segment de tige avant (5) pouvant être introduit dans une cavité appropriée pour le tournevis, sur la tête de la vis et dans lequel est aménagé au moins un renfoncement longitudinal (7) avec un axe longitudinal (8) orienté transversalement par rapport à l'axe longitudinal (3) ; et B) au moins un élément à effet ressort inséré dans le renfoncement (7) (au moins au nombre de un), faisant saillie transversalement à l'axe longitudinal (3) au-dessus de la surface de section transversale (9) du segment de tige avant (5), C) l'élément à effet ressort (6) étant à déformation élastique sur sa partie en saillie au-dessus de la surface de section transversale (9), transversalement à l'axe longitudinal (8) du renfoncement (7).
