[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1, Figure 1-4 A portable fire extinguisher, as shown, includes a canister 1. A nozzle 4 is mounted on the top of the canister 1, and a pressing block 5 is fixedly connected to the outer surface of the nozzle 4. An auxiliary device 2 is mounted on one side of the canister 1. The auxiliary device 2 includes two grooved rods 21 and an arc-shaped plate 24. One side of each of the two grooved rods 21 is fixedly connected to both sides of the canister 1. A groove 22 is formed on the outer surface of each grooved rod 21. Sliding plates 23 are fixedly connected to both ends of the arc-shaped plate 24. One end of each sliding plate 23 slides along the inner wall of the groove 22 on the outer surface of each grooved rod 21. A push block 25 is slidably connected to the inner wall of the arc-shaped plate 24. A rubber plate 26 is fixedly connected to one end of each push block 25. A spring 27 is mounted on the outer surface of each push block 25. The two ends of each spring 27 are fixedly connected to one side of the push block 25 and one side of the arc-shaped plate 24, respectively. Two operating blocks 28 are fixedly connected to one side of the arc-shaped plate 24. When using the fire extinguisher, the thumb and ring finger of one hand can be used to pinch the two operating blocks 28 on one side of the arc-shaped plate 24. The outer surface of the operating block 28 controls the arc plate 24 to move through the sliding plates 23 at both ends in the sliding groove 22 within the groove rod 21. Adjusting the high position of the sliding plate 23 makes it easy to place the index finger on the pressing block 5. Then, the palm is pressed against one side of the push block 25 to push the push block 25 towards the tank body 1 and compress the spring 27, pressing the rubber plate 26 at one end of the push block 25 against the outer surface of the tank body 1 to fix the arc plate 24 on one side of the tank body 1. Then, pressing the pressing block 5 controls the solid extinguishing agent inside the tank body 1 to be sprayed out through the nozzle 4 for fire extinguishing. By setting the auxiliary device 2, the fingers are pressed on the outer side of the two operating blocks 28 on one side of the arc plate 24, making it easy to pinch the outer surface of the arc plate 24 to control the tank body 1 for fire extinguishing operation. This avoids the tank body 1 from slipping when using the fire extinguisher and falling off. Furthermore, the arc plate 24 controls the tank body 1 so that the hand does not come into direct contact with the tank body 1 and is not affected by the increased internal and external temperature of the tank body 1, which affects the normal use of the fire extinguisher.

[0032] Figure 1 , Figure 2 and Figure 4The outer surface of the push block 25 shown is located inside the spring 27. The inner diameter of the spring 27 is slightly larger than the outer diameter of the push block 25. When the push block 25 moves and causes the spring 27 to deform, the spring 27 will move outside the push block 25. The push block 25 can reinforce the internal shape of the spring 27 and prevent the spring 27 from twisting as much as possible. An auxiliary groove 210 is provided on one side of the operating block 28. The inner wall of the auxiliary groove 210 is provided with an anti-slip rubber sheet. The anti-slip rubber sheet surface of the auxiliary groove 210 on the outer surface of the two operating blocks 28 can increase the friction between the finger surface and the outer surface of the operating block 28, and further improve the stability of the tank 1 when controlled by the arc plate 24.

[0033] Figure 2 and Figure 4 Two support rods 29 are fixedly connected to the outer surface of the arc plate 24 shown. The ends of the two support rods 29 away from the arc plate 24 are fixedly connected to one side of the operating block 28. By setting the support rods 29, the connection between the operating block 28 and the arc plate 24 can be reinforced, so as to avoid the connection between the operating block 28 and the arc plate 24 being tilted and broken as much as possible.

[0034] Figure 1-3 A positioning device 3 is provided on one side of the tank 1 shown. The positioning device 3 includes two L-shaped rods 31. A cylinder 32 is fixedly connected to one side of the L-shaped rods 31. A sliding rod 33 is slidably connected to the inner wall of the cylinder 32. A suction cup 34 is fixedly connected to one end of the sliding rod 33. When storing the fire extinguisher, the sliding rods 33 on the inner wall of the two cylinders 32 can be pulled to slide away from the tank 1, so that the two suction cups 34 are away from the side of the tank 1. Then the two suction cups 34 are attached to the flat surface, which can further restrict the position of the tank 1 at the storage location, making it easier to store the fire extinguisher and improving the convenience of using the fire extinguisher.

[0035] Figure 2 and Figure 3 A rectangular block 35 is fixedly connected to one side of the two sliding rods 33 that are close to each other. Several protruding strips are fixedly connected to one side of the rectangular block 35. By pressing the protruding strips on one side of the rectangular block 35 with your hand, you can more easily push the rectangular block 35 to control the movement of the two sliding rods 33. Adjusting the position of the sliding rods 33 and the suction cup 34 is convenient for using the positioning device 3.

[0036] Figure 2 and Figure 3A rectangular piece 36, made of rubber, is fixedly connected to one side of the suction cup 34. After the suction cup 34 is attached to the flat surface, when a fire extinguisher is needed, the suction cup 34 can be pulled by pinching the outer surface of the rubber rectangular piece 36 to make one side of the suction cup 34 tilt up, making it easier to control the suction cup 34 away from the suction surface. A positioning block 37 is fixedly connected to one end of the cylinder 32. The positioning block 37 is made of elastic metal. When the sliding rod 33 is pulled to move on the inner wall of the cylinder 32, one end of the elastic metal positioning block 37 will bend outward. After the sliding rod 33 is released, one end of the positioning block 37 will press against the outer surface of the sliding rod 33 to restrict the position between the sliding rod 33 and the cylinder 32.

[0037] Working principle: When storing the fire extinguisher, the sliding rods 33 on the inner walls of the two cylinders 32 can be pulled to slide away from the tank body 1, causing the two suction cups 34 to move away from the side of the tank body 1. The two suction cups 34 are then attached to the flat surface, further restricting the position of the tank body 1 at the storage location, facilitating the storage of the fire extinguisher. When using the fire extinguisher, pinch the outer surface of the rubber rectangular plate 36 and pull the suction cup 34 to lift one side of the suction cup 34. Then push the sliding rods 33 to move the suction cup 34 away from the suction surface. Use the thumb and ring finger of one hand to pinch the two suction cups on one side of the curved plate 24. The outer surface of the operating block 28 controls the arc plate 24 to move through the sliding plates 23 at both ends in the sliding groove 22 within the groove rod 21. Adjusting the high position of the sliding plate 23 makes it easy to place the index finger on the pressing block 5. Then, the palm is pressed against one side of the push block 25 to push the push block 25 towards the tank body 1 and compress the spring 27, pressing the rubber plate 26 at one end of the push block 25 against the outer surface of the tank body 1 to fix the arc plate 24 on one side of the tank body 1. Then, pressing the pressing block 5 controls the solid extinguishing agent inside the tank body 1 to be sprayed out through the nozzle 4 to extinguish the fire.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
