A positioning and painting assembly 24 is fixedly installed near the edge at the rear end of the vehicle frame 1, and the feeding pipe 23 is connected to the positioning and painting assembly 24. The positioning and painting assembly 24 includes a mounting frame 241, which is fixedly connected to the rear end of the vehicle frame 1 and extends out. Screws 242 are arranged at both the left and right ends inside the mounting frame 241 through bearings. Knobs 243 are arranged at one ends outside the screws 242. Moving blocks 244 are threadedly connected to the outer walls of the screws 242. Indicator plates 245 are fixedly connected to the bottom sides of the moving blocks 244. The inner walls of the indicator plates 245 and the outer walls of the mounting frame 241 are slidably connected. Scale lines 247 are arranged on one outer surface of the mounting frame 241. Painting heads 246 are fixedly connected to the bottom sides of the indicator plates 245. The feeding ports on one sides of the painting heads 246 are fixedly connected to the feeding pipe 23. By installing the auxiliary positioning device 2, the positions of the two painting heads 246 at both ends can be adjusted according to the distance between the markings at both ends. During adjustment, the indicator plates 245 move synchronously. The distance between the markings at both ends is calculated according to the scale lines 247, which is convenient for adjustment and marking. Moreover, the adjustable painting heads 246 have a larger applicable range.
