Protective structure of laser cutting machine

The utility model discloses a laser cutting machine protection structure, and relates to the technical field of laser cutting machines. The device comprises a laser generator, a cutting probe is fixedly installed at the bottom of the laser generator, protective plates are symmetrically arranged on the peripheral side of the cutting probe, inner rods are fixedly connected to the tops of the protective plates, the inner rods are slidably sleeved with outer rods, and the outer rods are connected with the laser generator; when the inner rod is accommodated by the outer rod. By adopting the design of the protection plate, when the laser generator collides with the plate, the cutting probe does not make contact with the plate body, so that the cutting probe cannot be damaged due to collision, and then by adopting the design of an inner rod, an outer rod and a compression spring, impact force generated when the protection plate collides with the plate can be absorbed; therefore, the vibration force transmitted to th
