  • the operator does not need to make the bracket unit 8 3 abut the workpiece, and the axial movement of the workpiece can activate the reset switch 84 to make the reset switch 84 moves axially along the chute 87 on the housing 6. Since the reset switch 84 is fixedly coupled to the bracket unit 8 3, the bracket unit 83 can be easily moved, and accordingly, the bracket unit 83 can also drive the support unit 81 to move axially. Thereby, the support unit 81 and the bracket unit 83 are returned from the current position to the initial position, which is advantageous for the next operation, and the operation is labor-saving.

Abstract

La présente invention se rapporte à un dispositif de support de vis (2) et à un outil de vissage (1). Le dispositif de support de vis (2) est utilisé pour aider l'outil de vissage (1) à positionner une vis, l'outil de vissage (1) ayant un axe d'arbre de sortie, le dispositif de support de vis (2) comprenant un logement (6), un mécanisme de venue en butée (7) destiné à venir buter contre la vis le long de la direction de l'axe d'arbre de sortie par le biais d'un embout de vis (703), un mécanisme d'entraînement situé dans le logement (6) et un mécanisme de support destiné à supporter une vis; le mécanisme de venue en butée (7) effectue un déplacement lors de la venue en butée contre la vis par le biais de l'embout de vis (703), et le mécanisme d'entraînement entraîne le déplacement du mécanisme de support jusqu'à la position pour supporter la vis en réaction au déplacement du mécanisme de venue en butée (7). L'outil de vissage (1) comprend un dispositif de support de vis (2) qui supports une vis en fonctionnement. Le dispositif de support de vis (2) peut supporter une vis automatiquement.
