The larger the effectiveness of the existing fire extinguisher is, the better, but the weaker is required to put a fire extinguisher with a national standard total weight of less than 20kg on hand, which is impossible, but the design problem is not put on hand, which is not effective, most eastern countries stipulate that the fire extinguisher must be put on the ground to be padded a little higher, with a box or a fire extinguisher seat that may be expensive over the fire extinguisher, because the eastern human body is slightly smaller than the western one, if it is difficult to take off and hang on the wall like the western one, but the western people change the height standard of the hanger the lower the height standard, because the foot is seriously injured if dropped, the foot drop is guaranteed to be injured no matter how low the height, and if a wheel is added, the cost is increased the other standard. Therefore, as shown in fig. 4 and 5, the fire extinguisher of the utility model can be installed on a small wheel vehicle and also can be installed on a hand buggy.

As shown in fig. 6, the present invention can also adopt the fire extinguisher structure as shown in fig. 6, the blocking valve 24 is disposed in the middle of the first rigid pipe 21, and the first rigid pipe 21 is provided with a plurality of round holes above the blocking valve 24; when in use, the valve 25 of the disposable broken pipe is broken, the first rigid pipe from the broken part to the uppermost part moves upwards to prop against the second barb cushion block 28, and the dry powder in the fire extinguisher bottle moves into the hose from the broken part and is sprayed out from the top outlet of the first rigid pipe 21 through a plurality of round holes.

The utility model has the advantages that:

the utility model discloses entangle flexible pipe 22 with second rigid pipe 23, second rigid pipe 23 calls the extension rupture handle, protect disposable rupture pipe valve 25 place not by the rupture, during the use take out safety cock 210 who goes up fixer 29, fold the safety rope and straighten and pull back again like air gun pressurization handle, this action equals to make once only rupture pipe valve 25 place rupture of making a round trip each, fire extinguishing agent jets out this moment, but the spring force of the spring on the spray gun pushes down and makes it stop at the spray gun, then jet out according to the valve handle down, accord with the fire extinguisher national standard.

The utility model discloses spray gun hose tail end is also spray gun mouth intraductal nothing: when the spray gun handle is used as a hose clamp, a fixed displacement device is clamped in the hose, and when the fixed displacement device is clamped by a spring, the fixed displacement device is closed and is opened to the maximum by hand.

The utility model discloses it is heavy that the smooth lower portion of extension handle swift current replaces carrying the hair: the handle is raised by one time, when 45 degrees, the total weight is reduced by more than half at once, the handle is inclined randomly, two radians slide on the ground in one direction, the handle is designed to slide only when a fire happens, the handle is not used for carrying when the fire happens, 4 feet/radians are also equal to the height of the pad, and the height of the pad does not have the chance of falling down to hurt people.

The utility model can be operated according to the standard, the situation that the powder can pass through completely is passed, namely, the 'fluidity tester' in the national standard of the dry powder extinguishing agent is arranged behind the glass bead window in the bottle, or the powder can be completely extracted out without decompressing during the national standard visual inspection, but the fluidity tester can be proportionally reduced to the situation that the discharge diameter of the fluidity tester is unqualified when the powder does not flow, rather than the time of freely passing through the discharge opening.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
