A clamping assembly for clamping the spray nozzle 16 is provided at the end of the damping shaft 18. During specific use, when using the handheld fire extinguisher, firstly, the mounting frame 19 is manually turned to rotate. The damping shaft 18 provides a certain amount of damping to prevent the mounting frame 19 from accidentally rotating. Secondly, the spray nozzle 16 is fixed by the provided clamping assembly, and then the safety pin 14 is pulled out. The handle 12 is held with one hand, and the pressure handle 13 is pressed with the other hand to aim the spray nozzle 16 at the fire source. The fire is extinguished by spraying the fire extinguishing agent through the spray nozzle 16. The device can be aimed at the fire source without taking the spray nozzle 16, and the operation can be completed with one hand. The design of the handheld fire extinguisher is very practical for disabled people who can only operate with one hand.

[0021] As an implementation method in this embodiment, Figure 1 and Figure 2As shown, the clamping assembly includes a lower clamping plate 20 fixedly connected to the mounting frame 19, an upper clamping plate 21 is hingedly connected to one side of the lower clamping plate 20, positioning grooves 22 are provided on the inner walls of the upper clamping plate 21 and the lower clamping plate 20, and positioning blocks 23 adapted to the positioning grooves 22 are fixedly connected to the outer walls on both sides opposite to the top of the nozzle 16, and a fixing assembly for fixing the upper clamping plate 21 and the lower clamping plate 20 is provided on one side of the upper clamping plate 21 and the lower clamping plate 20. During specific use, the nozzle 16 is first placed on the lower clamping plate 20, and at this time, the positioning block 23 of the nozzle 16 needs to be aligned with the positioning groove 22 for placement, and then the upper clamping plate 21 is rotated to the lower clamping plate 20, so as to fix the nozzle 16 between the lower clamping plate 20 and the upper clamping plate 21, and the positioning block 23 and the positioning groove 22 can prevent the nozzle 16 from moving.

[0022] As an implementation method in this embodiment, Figure 2 As shown, the fixing assembly includes an upper fixing plate 30 fixed on the upper clamping plate 21 and a lower fixing plate 31 fixed on the lower clamping plate 20, and the upper fixing plate 30 and the lower fixing plate 31 are inserted with matching threaded columns 32, and the threaded columns 32 are threadedly connected to the upper fixing plate 30 and the lower fixing plate 31, and the top of the threaded column 32 is fixedly connected with a knob 33. During specific use, when the upper clamping plate 21 is placed on the lower clamping plate 20, the threaded column 32 is inserted into the threaded holes reserved in the upper fixing plate 30 and the lower fixing plate 31, and then the knob 33 is manually turned to screw the threaded column 32 into the upper fixing plate 30 and the lower fixing plate 31.

[0023] As an implementation method in this embodiment, Figure 1 As shown, a first fixing ring 40 is fixedly connected to the upper end surface of the knob 33, a second fixing ring 41 is fixedly connected to the upper clamping plate 21, and an anti-lost rope 42 is arranged between the first fixing ring 40 and the second fixing ring 41. The anti-lost rope 42 is arranged to prevent the threaded column 32 from being randomly placed and lost when not in use.

[0024] As an implementation method in this embodiment, Figure 4 As shown, an arc-shaped limit frame 50 for fixing the nozzle 15 is fixedly connected to the side wall of the top of the mounting frame 19 close to the bottle body 10. When the mounting frame 19 is bent into a vertical state, the arc-shaped limit frame 50 fixes the nozzle 15 to prevent the nozzle 15 from swinging randomly and causing the top connection to loosen.

[0025] As an implementation method in this embodiment, Figure 1 As shown, hanging rings 60 are fixedly connected to the outer walls on both sides of the ring 17, and straps 61 are tied to the two hanging rings 60. The straps 61 are hung around the neck to reduce the gravity of the hands.

[0026] Working principle: When using a handheld fire extinguisher, first manually bend the mounting frame 19 to rotate it. The damping shaft 18 provides a certain amount of damping to prevent the mounting frame 19 from rotating accidentally. Secondly, first place the nozzle 16 on the lower clamping plate 20, and at this time, the positioning block 23 of the nozzle 16 needs to be aligned with the positioning groove 22 for placement, and then the upper clamping plate 21 is rotated to the lower clamping plate 20, so as to fix the nozzle 16 between the lower clamping plate 20 and the upper clamping plate 21, and the positioning block 23 and the positioning groove 22 can prevent the nozzle 16 from moving, and then pull out the safety pin 14, hold the handle 12 with one hand, press the pressure handle 13 with the other hand, aim the nozzle 16 at the fire source, and spray the fire extinguishing agent through the nozzle 16 to extinguish the fire.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
