Detailed Description
The following description will further describe a specific embodiment of the spray gun of the present invention with reference to fig. 1. The utility model relates to a spray gun convenient to dismouting is not limited to the description of following embodiment.
This embodiment provides a concrete structure of a spray gun convenient for disassembly and assembly, as shown in fig. 1 to 3, the spray gun convenient for disassembly and assembly includes:
the spray gun comprises a spray gun shell 2, a thimble 1 is inserted in the spray gun shell 2, and an air inlet 8 and a liquid inlet 9 are respectively arranged on the surface of the spray gun shell 2;
a nozzle pressure plate 3 fitted to one end of the spray gun housing 2 for positioning a nozzle 4 fitted to the surface of the spray gun housing 2; and
and the rear cover 7 is assembled at the other end of the spray gun shell 2, a compression spring 6 is arranged in the rear cover 7, and the compression spring 6 is sleeved at one end of the thimble 1.
