The axes of the additional ammunition slots 8 are vertical to the axis of the gun barrel, the fire extinguishing bombs are arranged in parallel in the guide grooves of the additional ammunition slots 8, and the lowermost bomb can slide into the magazine hole or the magazine groove of the movable cartridge clip 36. If necessary, a triangular magazine can be additionally arranged above the additional ammunition slots combined into a strip to increase the ammunition storage capacity.

When the magazine is in a groove shape, the additional magazine is arranged above the opening of the magazine groove, a flanging is arranged at the opening of the additional magazine, the flanging is fixed on the upper panel of the guide rail 19, and the bottom surface of the additional magazine is fixed on the reinforcing beam 6.

When the magazine is hole-shaped, one end of the additional spring slot is closed, the slot wall close to the closed end is fixed on the top surface of the guide rail 19, the slot bottom extending section close to the closed end is fixed on an angle iron sheet welded on the gas storage tank, and the slot wall close to the closed end is provided with a hole concentric with the spring loading holes on the two sides of the guide rail 19. The fire extinguishing bombs are arranged in parallel in the guide groove of the additional magazine 8, and the lowermost one can slide into the magazine hole of the movable cartridge holder 36.

When the magazine is hole-shaped, the fire extinguishing bomb can slide down to the hole of the magazine on the movable clip by gravity when the fire extinguishing cannon is shot obliquely, and the fire extinguishing bomb needs to be pushed manually or pneumatically when the fire extinguishing cannon is shot horizontally or shot obliquely at a small angle. The long plunger concentric with the loading hole can be driven by the bullet pushing cylinder 10 to push the fire extinguishing bullet, the plate at the bottom of the closed bullet groove is folded upwards to form an edge, the bullet pushing cylinder 10 is fixed on the folded edge, the axis of the cylinder is parallel to the axis of the gun barrel, the top of the long plunger is fixed with a pressing plate, and the cylinder rod is fixed on the pressing plate.

When the front and the rear fire extinguishing bomb are not far into the cartridge chamber hole of the movable cartridge clip 36, the arc-shaped inclined plane at the top of the cartridge chamber hole can push the rear fire extinguishing bomb.

In order to prevent the fire extinguishing bomb from being too short, the upper bomb simultaneously slides into the bomb chamber hole too deeply, so that the front and the rear two fire extinguishing bombs can be separated when sliding downwards, an elastic rotating hook pin 9 can be additionally arranged, the part of the head of the rotating hook pin, which extends into the bomb groove, is provided with an inclined surface, the inclined surface blocks the reducing part of the fire extinguishing bomb, the inclined surface can be jacked open when the long plunger pushes the fire extinguishing bomb, and the elastic rotating hook pin 9 is fixed below the tightly attached cylinder by a support.

A magnet assembly 13 is fixed to the muzzle of the barrel for exciting the programmable fire extinguishing bombs.

The gun body protective cover is used for beauty.

Although a slotted barrel can also perform the main function of the invention, it is clearly inferior to a box-shaped barrel in terms of strength and the possibility of housing the control air valves and the hinge mounts and enclosing the air valves and the electrical control box within the barrel.
