description The utility model discloses a trachea cannula fixing device, which relates to the technical field of medical instruments and comprises a fixing cover, an external tube is mounted in the middle of the fixing cover, a cannula hole is formed in the middle of the external tube, a trachea body is inserted into the cannula hole, and a plurality of inner grooves are formed in the inner wall of the external tube. The novel trachea cannula has the advantages that when the novel trachea cannula is used, only the outer sleeve needs to be pulled upwards, the spring in the guide groove is compressed, the outer sleeve is limited through the limiting ring, then the trapezoidal groove and the hole groove are located on the same level, then the trachea body is inserted into the cannula hole, the sliding rods can be pushed into the inner groove, and the trachea cannula is fixed. When the air pipe body is inserted into the lower portion of the rubber sealing ring, the outer sleeve is loosened, the spring rebounds to push the ou
