[0002] A spray gun is a device that uses liquid or compressed air to release quickly as power. Spray guns are divided into two types: general pressure type and pressurized type. There are also pressure spray guns, Carle spray guns, and automatic recovery spray guns. The application of spray guns in the industry can be directly loaded with paint, that is, a simple spray gun, which can be installed in automation equipment such as automatic glue spraying machines, automatic glue coating machines, automatic paint spraying machines, coating machines and other spraying equipment. The spray gun nozzles are quickly disassembled and assembled with the spray gun through quick-change connectors, but the existing spray gun nozzles and spray guns are generally fixedly connected by plug-in screws. This connection method is more cumbersome to operate and requires the use of tools to tighten the screws, resulting in low replacement efficiency. For this reason, we propose a melting quick-change connector. Utility Model Content
