Nozzle structure and mortar spraying gun
The invention provides a nozzle structure and a mortar spraying gun. The nozzle structure comprises a spraying gun head, an outer nozzle and an inner nozzle, wherein the outer nozzle is connected to the end part of the spraying gun head; the inner nozzle is arranged at the inner side of the outer nozzle; and the inner diameter of the inner nozzle is smaller than the minimum inner diameter of the outer nozzle. The mortar spraying gun comprises the nozzle structure. The nozzle structure only replaces the inner nozzle without needing to replace the whole outer nozzle when the mortar nozzle is worn, so that the material cost of the nozzle structure and the maintenance cost of the mortar spraying gun are reduced.
