載の塗料噴射ガン。[Scope of Claim for Utility Model Registration] (1) An injection gun body having a paint injection port at one end and a paint flow path and a gas flow path communicating with the injection port, and a paint injection of the injection gun body. A grip is provided on the injection gun body at a certain angle with respect to the direction, and a gas introduction channel and a paint introduction channel are provided in the grip, and both of the introduction channels are , respectively, communicate with the gas flow path and the paint flow path via gas and paint flow path on-off valves provided in the injection gun body, and each valve rod of both flow path on-off valves: A paint injection gun configured to open and close the flow passage opening/closing valves by engaging a lever handle pivotally connected to the injection gun body or the grip to an end projecting outside the injection gun body. (2) The valve rod of the gas passage opening/closing valve, which is biased in the closing direction by spring pressure, extends and protrudes from the injection gun body in a direction approximately parallel to the direction in which the grip is connected to the injection gun body. A valve rod engaging edge provided on the lever handle is in contact with the protruding end of the valve rod at an unequal distance from the center of rotation of the lever handle, and the engaging edge is in contact with the protruding end of the valve rod with respect to the center of rotation of the lever handle. 2. A paint spray gun according to claim 1, wherein the other end of the engaging piece is engaged with the valve rod of the paint passage opening/closing valve on one side of the opposite side. (3) The gas flow path is composed of a fumarole pipe that can be attached and detached to the discharge side of the gas flow path opening/closing valve, and the fumarole pipe is surrounded by a ring wall formed coaxially around the fume pipe. A paint flow path is provided, and the coating pattern is adjusted by rotating a nozzle cap screwed into the ring wall to move the distance between the paint injection port provided in the nozzle cap and the jet port of the blow tube. A paint spray gun according to claim 1 or 2, which is configured to do so.
