The invention provides a trigger adaptor to allow 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 comprises a tubular grip (24) surrounding the tool barrel (12) and freely rotatable around it. The grip (24) extends between upper (22) and lower (23) annular securing parts each of which is secured to the tool barrel. A longitudinal groove (24) in the grip carries an auxiliary trigger bar (26) pivoted at its lower end on a pin (35). When the trigger bar (26) is squeezed inwardly, its upper end bears on the underside of a flange (37) at the top of a tube (27). When the flange (37) rises it drives up a pushrod (25), which contacts the tool trigger (15) and moves it to actuate the tool.
