[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0016] The following is combined with Figure 1-2 This application is described in further detail.

[0017] A square adjustable two-color main nozzle comprises: a support plate 1, a bracket 2, a rivet nut 3 and a fixing screw 4, the bracket 2 is provided with two groups of nozzle assemblies, the support plate 1 is provided with a plurality of mounting holes 5, the bracket 2 is provided with a plurality of waist-shaped holes 6, the positions of the mounting holes 5 and the waist-shaped holes 6 correspond, the rivet nut 3 extends into the mounting hole 5, the fixing screw 4 passes through the waist-shaped hole 6 and is threadedly connected with the rivet nut 3.

[0018] The waist-shaped hole 6 allows the bracket 2 to be adjusted at a small angle when it is fixed to the support plate 1, so that the angle of the nozzle can be adjusted, which makes it easy to adjust the angle of the nozzle according to actual needs.

[0019] In one embodiment, there are two waist-shaped holes 6 , and the waist-shaped holes 6 allow the entire nozzle structure to have an adjustment angle of 2 degrees to the left and right.

[0020] In one embodiment, the bracket 2 includes an aluminum sleeve 21 , a backing plate 22 and a pressing block 23 . The aluminum sleeve 21 , the backing plate 22 and the pressing block 23 are integrated, and the waist-shaped hole 6 is provided in the backing plate 22 .

[0021] The aluminum sleeve 21, the backing plate 22 and the pressing block 23 are integrated so that the machining process of the machine tool is reduced when producing the bracket 2, and the assembly process of the whole device is reduced, thereby improving the assembly efficiency. At the same time, the integrated bracket 2 helps to improve the consistency of the whole device.

[0022] In one embodiment, the nozzle assembly includes a nozzle core 7, an air inlet connector 8, a connecting pipe 9 and a main nozzle 10. The nozzle core 7, the air inlet connector 8 and the connecting pipe 9 are all arranged on the aluminum sleeve 21. The nozzle core 7 and the connecting pipe 9 are arranged on opposite side walls of the aluminum sleeve 21.
