[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0023] Please refer to Figures 1-5 , a spray nozzle that is easy to replace for an ink spraying machine, including an ink nozzle 1. A mounting insertion ring 2 is fixedly connected to the top of the ink nozzle 1. A slider 3 is fixedly connected to the outer wall of the mounting insertion ring 2. A convex block 4 is movably connected inside the slider 3. A fixed disk 5 is installed on the outer wall of the mounting insertion ring 2. A chute 6 is opened inside the fixed disk 5. A clamping groove 7 is opened on the inner side wall of the chute 6. The mounting insertion ring 2 is movably connected to the fixed disk 5, and the slider 3 forms a sliding structure with the fixed disk 5 through the chute 6. The chute 6 is L-shaped, and the convex block 4 is snap-connected to the fixed disk 5 through the clamping groove 7. A spring is fixedly connected to one side of the convex block 4, and the convex block 4 forms a sliding structure with the slider 3.
