Abstract:
1. Pruning scissors comprising a blade and a counter-blade each integral with a grip and mounted so as to be pivoted around a threaded swivel pin which cooperates with an adjusting nut of the blade and counter-blade, the adjusting nut being rotationally integral with a toothed wheel engaged with a retainer toothed member attached to the counter-blade through a blocking screw, wherein said toothed wheel is separated from the adjusting nut and has an axial opening whose outline corresponds to an external outline of the adjusting nut and is inserted around the adjusting nut and rotates therewith, and wherein the toothed wheel is fixed to a toothed wheel washer which itself has an axial opening whose outline corresponds to an external outline of the adjusting nut, is inserted around said adjusting nut and rotates therewith and is interposed between the counter-blade and the toothed wheel, wherein the toothed member is a toothed gear, and the toothed gear is positioned at the same level as the toothed wheel by a second washer interposed between the counter-blade and the gear, wherein said toothed wheel washer has a radius which is greater than an outer radius of the teeth of said toothed wheel but is less than a distance between a centerline of said adjusting nut and a periphery of said second washer, wherein said second washer has a radius less than a distance between a centerline of said blocking screw and a periphery of said toothed wheel washer, so that when the toothed gear is engaged with the toothed wheel the gear teeth cover the peripheral edge of the toothed wheel washer, thereby retaining the toothed wheel washer and consequently the toothed wheel around the adjusting nut against any axial displacement.
