Title: Safety improvements for power tool

Abstract: A hand-held power tool includes a cutting blade within a housing (5) and a guard (10) placed over the operating head of the tool. The guard is movable in the direction (1) in order to expose the blade during cutting. The sliding mechanism is improved by maintaining alignment between the guard and the head over a larger distance. In one embodiment, this is achieved by sliders (FIG. 8) in grooves (9). Contact over a larger range reduces the likelihood of jamming and improves handle precision. Alternative embodiments provide structure for indicating the blade position (FIG. 11), and a frangible retaining washer for disengaging the cutting blade (FIGS. 13 to 15).
