The fixing portion 463 of the spray cap 46 is concave, while the fixing portion 442 of the positioning ring 44 is convex, so that the two can be fixed. The setting of the lug 462 makes the sprayed area of the spray paint not a circle, but an ellipse.

A spray cap ring 47 is sleeved on the spray cap 46 and screwed on the air inlet piece 43 .

Referring to Fig. 4 to Fig. 6, it is the schematic diagram of painting of the utility model. The trigger 13 of the utility model is buckled and pressed, and can be divided into continuous type and discontinuous type. When the user wants to use the spray gun continuously, he can press the trigger 13 by means of the hook 15 to spray paint continuously, reducing the operator's hand fatigue. But if run into intermittent painting, the operator can manually operate to control whether painting or not voluntarily, without the help of the described hook 15. In the utility model, the gun body 10 corresponds to the trigger 13 and is provided with a bounce device 16. When the trigger 13 is not pressed, the bounce device 16 will automatically bounce against the trigger 13. Trigger 13, and make described spray gun form the closed state.

When the trigger 13 is pressed, the control member 14 is moved from the air-closed position in FIG. 4 to the open position in FIG. Leave the nozzle 451, and make the through hole 111 unblocked. The paint material of the spray paint comes out from the through hole 111 , while the gas comes out from the air intake groove 113 .
