Coating machine spray gun pull rod braking device

The invention discloses a coating machine spray gun pull rod braking device, and relates to the technical field of coating machines. The coating machine comprises a shell, a coating machine barrel, a sliding rail, a sliding rod, a pull rod, a spray gun supporting rod and a spray gun assembly, the sliding rod is matched with the sliding rail so that the sliding rod can slide in the direction of the sliding rail, the sliding rail is fixedly connected to the top of the shell, and the coating machine barrel is arranged in the shell; one end of the pull rod is fixedly connected and matched with the sliding rod, and the other end is connected and matched with the spray gun supporting rod. By arranging the pull rod, the spray gun assembly can be transversely pulled out and can also rotate, follow-up maintenance is facilitated, when the spray gun assembly is normally transversely pulled out, the spray gun supporting rod is lifted through the supporting plate, the stability of the spray gun supporting rod is guarantee
