Abstract

There are many trimmer models with 2 main parts, the static comb blade and the side moving cutter blade driven by electric motor/vibrator. These blades differ in many ways, shapes, sizes . . . which require fine adjustments and tenth of millimeter clearance at the end of the blades. Some models come with an adjuster that fits its model only with a fixed clearance that cannot be modified and does not fit other models. The proposed inventions are universal trimmer blades adjusters that fit most trimmer blades models and the clearance can be varied to meet the users' requirements. First invention design has one moving part with non-linear smooth adjustments and second invention design has two moving parts with linear fine adjustments.
