Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Society use fields] Fire extinguishers have safety plugs because they must be accidentally radiated when they are carried. Even if you accidentally forget to remove the safety plug in the event of a fire, the safety plug is automatically released when you lift the hose toward the fire,
Reliable operation is expected.

[0002]

Conventional use and disadvantages Conventionally, the fire extinguisher cannot be used unless the safety plug is pulled out by holding the main body. There are many cases where the method of releasing the safety plug was not known and could not be actually used.

[0003]

[Effects of the Invention] The present invention has the effect of a safety plug, so even if you do not know how to use a fire extinguisher at all, or if you forget to use the safety plug, use it in the conventional way. It can radiate quickly because it does not hurt anything.

[0004]

When the hose is lifted, the lot or wire connected to the curved portion of the hose is pushed, and the stopper is released. Next, anyone can tell that the safety plug has jumped up by several tens of centimeters due to the pressure of the spring and has been released.
