A hand-held fire extinguishing apparatus, the embodiment of which is shown in figure 1:

comprises a tank body 1, a siphon pipe 13 arranged in the tank body 1 and a head valve body arranged at the top of the tank body 1.

A handle is fixedly arranged at the top of the tank body 1, and a safety pin 4 is also inserted at one side of the handle. The handle is divided into two parts, namely a pressing handle 2 and a lifting handle, the pressing handle 2 and the lifting handle are mutually hinged, and the pressing handle 2 is arranged above the lifting handle.

The top of the tank body 1 is also provided with a pressure gauge 5 communicated with a valve body of the machine head, and the tail end of the valve body of the machine head is connected with a connecting hose 9. An adjusting nozzle is arranged at the tail end of the connecting hose 9.

In the tank 1, dry powder 14 is filled, a siphon tube 13 installed in the tank 1 extends to the inner bottom surface of the tank 1, and high-pressure gas is filled in the tank 1 above the dry powder 14. When the safety pin is not used normally, the safety pin 4 on the handle is inserted between the pressing handle 2 and the handle, and the safety pin 4 can be taken out for use.

As shown in fig. 1 and 2, the adjusting spray head comprises a fixed pipeline communicated with a connecting hose 9, four connecting rods 7 respectively hinged around the fixed pipeline, baffle plates 6 respectively arranged on two sides of the connecting rods and a reset piece arranged between the tail ends of the connecting rods 7.
