[0019] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is explained in detail below with the figures and specific embodiment. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not limited to the utility model.

[0020] In the description of the utility model, it is understood that the directions or position relations indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the directions or position relations shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0021] As shown in Figure 1 , 2 , the air switch wiring device comprises a wiring part 20 and a clamping part 10, the length and width of the clamping part 10 are greater than the length and width of the wiring part 20; the clamping part 10 comprises an upper metal sheet 11 and a lower metal sheet 12, one end of the upper metal sheet 11 and the lower metal sheet 12 is connected with the wiring part 20 integrally, and the wiring part 20 is provided with a wiring threaded hole 21; a spring washer 30 is embedded between the upper metal sheet 11 and the lower metal sheet 12; in order to avoid the spring washer 30 from coming out, one end of the upper metal sheet 11 and the lower metal sheet 12 away from the wiring part 20 is provided with an inward flanging structure, and the two side edges of the upper metal sheet 11 and the lower metal sheet 12 are provided with inward flanging structures; the outer surfaces of the upper metal sheet 11 and the lower metal sheet 12 are provided with anti-skid lines.

[0022] As shown in Figure 3 , 4 , 5, the air switch 40 comprises a shell 41, a fixed pressing wire sheet 42, a movable wiring frame 43 and a bolt 44, the movable wiring frame 43 is in the shape of "Fang" character, the upper end of the movable wiring frame 43 is movably connected with the shell 41 through the bolt 44, and the lower end of the movable wiring frame 43 forms a wire inlet between the fixed pressing wire sheet 42.
