Abstract:
1. A versatile adjustable stylus for a key duplicating machine, comprising an arm laterally secured at one end on the periphery of a cylindrical body, and laterally movably attached at an other end to a substrate by an engagement base secured on the substrate of the said key duplicating machine, wherein the direction of lateral movement is generally parallel to the longitudinal axis of an original key to be duplicated and the rotational axis of a duplicating cutter, whereby the arm and the cylindrical body are arranged to move closer to or further away from the duplicating cutter in accordance with different duplicating distances between the duplicating cutter and the original key to be duplicated; a retractable spring-loaded tracer movably engaged in one end of the said cylindrical body, for pre-tracing depths of key teeth of an original key; and a regulating grip angularly movably engaged in an other end of the said cylindrical body, for regulating retractable movement amount of the said retractable spring-loaded tracer.
