[0020] refer to Figure 1 , Figure 3 A fixing ring 2 is fixedly installed on the outer surface of the fire extinguisher body 1 near the top, a hinge block 3 is fixedly installed on the outer surface of the fixing ring 2, an adjusting plate 4 is hinged inside the hinge block 3, and a holding handle 13 is fixedly installed on the side of the adjusting plate 4; the setting of the fixing ring 2 facilitates the installation and fixation of the hinge block 3, and the setting of the hinge block 3 facilitates the internal rotation of the adjusting plate 4, so that the opening and storage of the adjusting plate 4 are convenient.

[0021] refer to Figure 1 , Figure 2 A U-shaped limit plate 5 is fixedly installed on one side of the adjustment plate 4, and a rubber pad 14 is fixedly installed inside the U-shaped limit plate 5; the U-shaped limit plate 5 is provided to facilitate the limiting and fixing of the nozzle / injection head on the fire extinguisher body 1, and the rubber pad 14 is provided to avoid friction between the nozzle / injection head and the inner wall of the U-shaped limit plate 5 as much as possible.

[0022] refer to Figure 1 , Figure 2 The inner bottom surface of the U-shaped limiting plate 5 is provided with a circular groove 6, and the front side of the U-shaped limiting plate 5 is provided with a circular hole 7 corresponding to the circular groove 6. The inner part of the circular hole 7 is plugged with a limiting plug post 8, and one end of the limiting plug post 8 passes through the circular hole 7 and extends to the inner part of the circular groove 6. A magnetic block 9 is fixedly installed in the inner part of the circular groove 6, and the magnetic block 9 and one end of the limiting plug post 8 are adsorbed with an iron sheet; the user first puts the nozzle on the fire extinguisher body 1 into the interior of the U-shaped limiting plate 5, and then inserts one end of the limiting plug post 8 into the interior of the circular hole 7 and the circular groove 6. When the limiting plug post 8 enters the interior of the circular groove 6, the magnetic block 9 and the iron sheet installed at one end of the limiting plug post 8 are attracted to each other, thereby facilitating the fixing of the limiting plug post 8, so that the limiting plug post 8 can limit the nozzle inside the U-shaped limiting plate 5 so that it will not break away from the interior of the U-shaped limiting plate 5.

[0023] refer to Figure 1 , Figure 2 and Figure 3 A fixing ring 2 10 is fixedly installed on the outer surface of the fire extinguisher body 1 near the bottom end.

A connecting piece 12 is installed on the back side of the adjusting plate 4. The magnetic block 2 11 and the connecting piece 12 are adsorbed together. By setting the fixing ring 2 and the fixing ring 10 to have the same size, it is convenient for the magnetic block 2 11 and the connecting piece 12 to be adsorbed together, so that the adjusting plate 4 can be effectively fixed and stored conveniently.

[0024] The implementation principle of the embodiment of the fire extinguisher of the present application that can prevent the spray head from swinging is as follows: the user first puts the nozzle on the fire extinguisher body 1 into the interior of the U-shaped limiting plate 5, and then inserts one end of the limiting plug 8 into the circular hole 7 and the circular groove 6. When the limiting plug 8 enters the interior of the circular groove 6, the magnetic block 9 and the iron sheet installed on one end of the limiting plug 8 are attracted to each other, so that it is convenient to fix the limiting plug 8, so that the limiting plug 8 can limit the nozzle inside the U-shaped limiting plate 5 so that it will not leave the interior of the U-shaped limiting plate 5. Then the user rotates the adjustment plate 4 by holding the handle 13. When the adjustment plate 4 is rotated and adjusted, it is convenient to drive the nozzle inside the U-shaped limiting plate 5 to adjust the angle, thereby improving the fire extinguishing efficiency. The device has a simple structure and is easy to operate. The U-shaped limiting plate 5 is set to facilitate the limiting and fixing of the nozzle, so that the nozzle will not swing left and right when the fire extinguisher body 1 is opened, and the angle of the nozzle can be effectively adjusted by the adjustment plate 4, thereby improving convenience.
