Abstract

La présente invention concerne un tournevis à spirale. Dans le tournevis à spirale selon la présente invention, une rainure en spirale d'un écrou à billes est accouplée à un écrou hexagonal disposé à l'extrémité arrière d'une tige mobile constituant une vis à billes, de façon à empêcher une marche à vide de la vis à billes, et un outil d'entraînement est accouplé à une rainure concave d'assemblage de la tige mobile et peut ainsi effectuer un serrage et un desserrage de vis d'assemblage. En outre, un boîtier d'écrou à billes peut être tiré vers le haut et déplacé par la force de compression d'un ressort élastique et la force de rotation d'une bille d'acier par la rainure en spirale d'un arbre de vis et de l'écrou à billes, et le boîtier d'écrou à billes ayant été déplacé vers le haut peut être déplacé vers le bas par la force de rappel du ressort élastique, de telle sorte que les vis d'assemblage peuvent être rapidement fixées ou desserrées d'une main. Par conséquent, la présente invention a une excellente maniabilité.
