This utility model relates to the field of water-jet looms and discloses a nozzle structure for a polyester water-jet loom, including a limiting ring fixed to the outer wall of the nozzle body. The limiting ring has several receiving holes, and the inner wall of each receiving hole has a receiving groove. A magnet is fixed to the inner wall of the receiving groove. A fixing cover is provided at one end of the nozzle body, and the fixing cover has a through hole corresponding to the nozzle body. Several L-shaped retaining strips are fixed to the fixing cover, and these L-shaped retaining strips are magnetically attracted to the magnet. In this utility model, through the synergistic action of the receiving groove, magnet, fixing cover, and L-shaped retaining strips, the nozzle core can be axially limited and circumferentially locked under the action of the pressing ring, ensuring greater stability of the nozzle core within the inner wall of the nozzle body. This effectively prevents the fixing cover from rotating due to vibration and avoids the risk of the nozzle core falling out of the nozzle body.
