6. The alloy spray gun for manufacturing the cooking pot body according to claim 1, wherein: the bottom and the side of movable rod (9) all are provided with vibrating diaphragm (91), and vibrating diaphragm (91) of bottom and vibrating diaphragm (91) of side are linked together, are located on same cross section rotary rod (6) surface evenly encircles and is provided with six movable rod (9).
7. The spraying method of the alloy spraying gun for manufacturing the cooking pot body as claimed in claim 1, comprising the following steps:
firstly, starting a spraying gun, enabling high-pressure gas to enter a transition pipe (11) through a gun barrel (1), enabling the gas to be in contact with a flow dividing piece, arranging flow dividing strips (41) on the surface of the flow dividing piece to enable the gas to be uniformly divided into three parts, enabling the divided gas to enter air holes (21) along the surface of a flow dividing cover (4), and finally enabling the gas to be discharged from the air holes (21) to be in a rotational flow shape through the shape arrangement of the air holes (21);
secondly, simultaneously, the powder box (3) is opened, so that the powder in the powder box (3) is discharged into the middle groove (23) through the feeding pipe (31);
thirdly, in an initial state, the position of the movable plug (7) under the action of spring tension is close to the shunting cover (4), the front hole (42) and the rear hole (51) are in a coincident state, namely a gas channel is opened, when gas passes through the gas channel and enters the middle groove (23), the thrust of the gas drives the movable plug (7) to move towards the side of a pushing piece, the deformation and expansion of the rubber film (8) are realized, so that powder entering the middle groove (23) is extruded and discharged into the material hole (22), and under the shape setting of the material hole (22), the powder is finally discharged out of the material hole (22) and then is in a rotational flow shape;
fourthly, the movable plug (7) moves towards the pushing piece to operate to drive the rotating rod (6) to rotate forwards for 320 degrees, and further drive the blocking block (5) to rotate forwards, the rotation of the blocking block (5) enables the rear hole (51) not to coincide with the front hole (42), the gas channel is closed, gas cannot enter the middle groove (23) linearly, and therefore the movable plug (7) moves reversely under the action of the spring force and drives the rotating rod (6) to rotate reversely for 320 degrees, the initial state is recovered, namely the rear hole (51) coincides with the front hole (42), and the gas channel is opened;
fifthly, the forward and reverse reciprocating rotation of the rotating rod (6) drives the movable rod (9) to rotate, so that the powder stored in the middle groove (23) is lifted, the powder moves towards the axis of the middle groove (23), and the powder is enabled to uniformly enter each material hole (22).
