Abstract: A laser engraving machine having dual quick release mirror holders is provided. The laser engraving machine comprises a machine station, a first mirror holder and a second mirror holder. The machine station has a working platform, a rail and a first laser tube. The first mirror holder is disposed on the rail and receives the laser light emitted from the first laser tube for carrying out a laser processing on the working platform when moves back and forth on the rail. The second mirror holder is composed of a second laser tube assembled on an output module, wherein the output module has a first binding portion and a second binding portion. The first binding portion detachably attaches to the rail for the second mirror holder to move on the rail. The second binding portion detachably attaches to the first mirror holder.

Abstract: A laser cutting and engraving machine with a fire safety mechanism, comprising a machine body, a laser engraving mechanism provided in the machine body, and a work platform. The laser engraving mechanism is mounted on a work track and is movable along the work track to cut or engrave a workpiece provided on the work platform. The fire safety mechanism is provided in the machine body. The fire safety mechanism comprises a fire source sensing unit, a fire extinguishing unit, and a control unit, in which the control unit is electrically connected to the fire source sensing unit and the fire extinguishing unit, and it receives and processes a signal delivered from the fire source sensing unit to determine if the machine body is ignited and thereby controlling the activation of the fire extinguishing unit.
