Abstract

Une structure de maintien de tige de tournevis, en particulier une structure de maintien de tige de tournevis pour une tige d'outil facilement amovible et échangeable, comporte un objet de fixation placé à une extrémité de la gaine de maintien, et un objet de libération attaché sur l'objet de fixation qui peut se déplacer de façon rectiligne et ne peut pas tourner. Une tige d'outils est située dans l'objet de libération et l'objet de fixation. L'objet de libération comprend deux plaques de fixation élastiques pour attacher la tige d'outils. Un bloc poussoir est disposé sur l'objet de fixation de façon à exercer une pression contre les plaques de fixation élastiques, de telle sorte que les plaques de fixation élastiques libèrent la tige d'outils. Selon la structure décrite ci-dessus, l'utilisateur utilise l'objet de libération pour attacher la tige d'outils, quand la tige d'outil est insérée dans l'objet de libération et l'objet de fixation. Et l'objet de libération permet au bloc poussoir de l'objet de fixation de repousser la plaque de fixation élastique, quand l'utilisateur appuie vers le haut sur l'objet de libération, permettant ainsi à l'utilisateur de changer la tige d'outil facilement et d'améliorer la commodité d'utilisation.
