Control nozzle / Fire extinguisher nozzle

[Control nozzle]
Fire extinguisher nozzle with the controllable spray angle.
The traditional nozzle of a fire extinguisher cannot control the range of spray. So it is inefficient to put out a fire according to the fire area. The control nozzle which improved the problem can control the spray angle of the powder extinguisher only by adjusting the lever to the left and right. Because of that, it can be applied broadly for a wide range or a narrow range of fire.
