Abstract
A stroke controller is mounted on a key duplicator and has a base, a drive shaft, a knob and a driven shaft. The base has a longitudinal shaft hole and a transverse shaft hole. The drive shaft is mounted rotatably through the transverse shaft hole. The knob is mounted on the drive shaft and has a drive gear. The driven shaft is mounted slidably through the longitudinal shaft hole and has a rack section engaging the drive shaft so that rotating the knob drives the driven shaft to slide relative to the base. The stroke controller precisely controls the movement of an original key and a key workpiece clamped on the key duplicator to manufacture a fine key duplicate.
