Abstract
A trigger adaptor allowing a conventional pistol-grip type hand held power tool to be used when suspended pointing vertically downwards, so that the operator may grip the tool and position it where desired and still be able to actuate the tool trigger. The adaptor includes a tubular grip surrounding the tool barrel and freely rotatable around it. The grip extends between upper and lower annular securing parts each of which is secured to the tool barrel. A longitudinal groove in the grip carries an auxiliary trigger bar pivoted at a lower end thereof on a pin. When the trigger bar is squeezed inwardly, its upper end bears on the underside of a flange at the top of a tube. When the flange rises it drives up a pushrod, which contacts the tool trigger and moves it to actuate the tool.
