摘要（英）：

The utility model provides a cutting torch and relates to the field of metal cutting devices. The cutting torch comprises a case, an inner core and a lower nozzle. The inner core and the lower nozzle are arranged in the case. The inner core is connected with the lower nozzle which comprises a lower nozzle base, a nozzle core and a lower nozzle sleeve. The cutting torch has the advantages that the nozzle core of the cutting torch and the lower nozzle base are matched through a two-layer tower structure, and therefore the sealing property of the cutting torch is improved; the lower nozzle is provided with a preheating hole, a Laval spraying nozzle is adopted in the inner core, and therefore flame spurt from the cutting torch is high in penetrating power, in the cutting process, a cut seam is small, a cut face is flat, the cutting efficiency is effectively improved, and sources are saved.
