Abstract

Selon un mode de réalisation, il s'agit d'un système de saisie de clé à tiges qui permet de visser ensemble des tiges de forage et de les dévisser. Le système de saisie est fixé à l'élément rotatif de la clé à tiges. Le système de saisie comprend une mâchoire active et deux mâchoires statiques à l'intérieur de l'élément rotatif. De préférence, les deux mâchoires statiques sont à moins de 120 degrés l'une de l'autre et sont fixées à l'élément rotatif de manière à pouvoir pivoter. Le système de saisie est conçu et disposé de manière à permettre à chaque mâchoire statique d'imprimer une force égale à la force de préhension appliquée par la mâchoire active. Dans un autre mode de réalisation, un appareil de verrouillage rotatif permet de verrouiller ou de déverrouiller l'élément rotatif de la clé à tiges.
