Abstract

L'invention concerne un appareil d'aide à la fixation de vis, comprenant une tige de manchon (100). La tige de manchon (100) présente une cavité interne creuse, et est remplie d'un agent de protection qui peut former une couche de protection sur la surface d'une vis. Une extrémité avant (110) de la tige de manchon (100) est utilisée pour monter une tête de vis, et l'extrémité avant (110) est pourvue d'un canal d'écoulement (200) en communication avec la cavité interne creuse. Une extrémité arrière (120) peut être connectée à une extrémité rotative d'un outil de vissage, et peut amener la tige de manchon (100) à tourner de manière synchrone avec l'extrémité rotative. Lorsque la tige de manchon (100) tourne, l'agent de protection s'écoule à travers le canal d'écoulement (200) jusqu'à un côté de vis. Lorsque l'outil de vissage entraîne la tige de manchon à tourner de manière synchrone pour visser une vis dans un élément à fixer, l'agent protecteur s'écoule de la cavité interne creuse vers le côté de la vis à travers le canal d'écoulement, et est distribué sur la surface de la tête de vis pour former un nouveau revêtement protecteur, ce qui permet de protéger efficacement la vis et d'améliorer la résistance à la corrosion et la sécurité d'utilisation de la vis.
