Abstract

La présente invention concerne une tige télescopique (10) pour un outil à main, comprenant un tuyau interne (20), un tuyau externe (30) imbriqué sur le tuyau interne, et un ensemble de positionnement (40) disposé sur le tuyau externe. L'ensemble de positionnement comporte un bloc coulissant (42), une goupille de positionnement (46) et un bouton de commande (43). Le bloc coulissant est disposé de manière coulissante sur le tuyau externe, et a une partie supérieure de poussée (421) et une fente de guidage (424) disposé dans la partie supérieure de poussée. La goupille de positionnement peut se déplacer dans le sens axial et passer à travers la fente de guidage du bloc coulissant et vient buter contre la partie supérieure de poussée du bloc coulissant. Le bouton de commande est connecté au bloc coulissant par une pièce de raccordement (44) pour conduire le bloc coulissant à se déplacer. Lorsque le bloc coulissant se déplace dans le sens axial le long du tuyau externe par la traction du bouton de commande, la partie supérieure de poussée du bloc coulissant pousse la goupille de positionnement pour séparer la partie inférieure de la goupille de positionnement depuis un trou de positionnement (22) du tuyau interne, c'est-à-dire, une position relative entre les tuyaux internes et externes est réglable de manière à atteindre le but de réglage de la longueur.
