Screwdriving end fitting for a screwdriving tool and a screwdriving tool including such an end fitting

Abstract

A screwdriving end fitting for a screwdriving tool for tightening a self-breaking fastener, such as a self-breaking nut or screw, includes a screwdriving socket and a retention module. The self-breaking fastener includes a threaded portion linked to a screwdriving head via a breaking area. The screwdriving socket of the screwdriving end fitting is capable of cooperating with the self-breaking fastener in order to drive it in rotation, and the retention module retains a broken portion of the self-breaking fastener in the screwdriving socket after the fastener has broken. The retention module includes at least one retainer movable between a locked position in which the retainer inhibits the broken portion of the self-breaking fastener from exiting the screwdriving socket and an unlocked position in which the retainer allows this exit.

Dependencies are inferred from the claim text.
