Abstract[English]
Drill bit adapter (100) and an electric tool. The drill bit adapter comprises: an outer sleeve (110), having a first through-hole (111) arranged in an axial direction; an inner sleeve (120), mounted in the first through-hole in the axial direction, and having a second through-hole (121) arranged in the axial direction; a shank (130), fixedly connected to the inner sleeve, wherein the outer sleeve and the inner sleeve are able to reciprocate in the axial direction, so that the first through-hole or the second through-hole is selectively exposed at an end of the drill bit adapter that is remote from the shank; and wherein the exposed first through-hole and second through-hole are used to mount a first fastener (210) and a second fastener (220) having different dimensions. This enables the connection and operation of fasteners of two different dimensions. As switching is achieved by forward and backward movement, a switching action during a job is simplified.[French]
Adaptateur de trépan (100) et outil électrique. L'adaptateur de trépan comprend : un manchon externe (110), ayant un premier trou traversant (111) disposé dans une direction axiale ; un manchon interne (120), monté dans le premier trou traversant dans la direction axiale, et ayant un second trou traversant (121) disposé dans la direction axiale ; une tige (130), reliée de manière fixe au manchon interne, le manchon externe et le manchon interne étant capables d'effectuer un mouvement de va-et-vient dans la direction axiale, de telle sorte que le premier trou traversant ou le second trou traversant est sélectivement exposé à une extrémité de l'adaptateur de trépan qui est à distance de la tige ; et le premier trou traversant et le second trou traversant exposés étant utilisés pour monter un premier élément de fixation (210) et un second élément de fixation (220) ayant des dimensions différentes. Ceci permet la connexion et le fonctionnement d'éléments de fixation ayant deux dimensions différentes. Comme la commutation est réalisée par un mouvement vers l'avant et vers l'arrière, une action de commutation pendant une tâche est simplifiée.
