Abstract
A laser marker including a laser marker body to hold a battery power supply and a control circuit, a laser module pivotably connected to the laser marker body and controlled by a push-button switch of the control circuit board to emit a laser beam, a set of laser firing caps alternatively mounted on the laser module to refract the laser beam by a respective plano-convex length of different focal length for marking a line of light on a workpiece for guiding a cutting tool to cut the workpiece. The laser module can be turned on laser marker body around the X-axis; the laser firing cap can be turned on the laser module around the Y-axis.
