In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0022] See also Figure 1-4 A fire-proof fire extinguisher comprises a fire extinguisher body 1. The outer wall of the fire extinguisher body 1 is sleeved with two sleeves 2 distributed up and down. The upper and lower sides of the outer walls of the two sleeves 2 are fixedly connected with a plurality of ear blocks 3 distributed in an array. Connecting rods 4 are fixedly connected between the plurality of ear blocks 3. The outer walls of the two connecting rods 4 on the same side are sleeved with elastic members 10.
[0023] In this embodiment: when the fire extinguisher body 1 is hit or dropped, the impact force acts on the elastic member 10, causing the elastic member 10 to deform, thereby buffering the impact force. After the elastic member 10 is subjected to the impact force, its two ends slide upward and downward along the connecting rod 4 respectively, and the impact force is further buffered by the spring 8, thereby preventing the fire extinguisher body 1 from exploding after being subjected to the impact force.
[0024] As a technical optimization solution of the utility model, the outer walls of the two sleeves 2 are each provided with a notch 9, and connecting plates 5 are fixedly connected on both sides of the two notches 9. Bolts 6 are installed between the two connecting plates 5 located on the same vertical line, and nuts 7 are threadedly connected to the outer walls of the two bolts 6.
[0025] In this embodiment: during installation, the two sleeves 2 are sequentially sleeved on the outer wall of the fire extinguisher body 1, and the two sleeves 2 are fixed to the upper and lower ends of the fire extinguisher body 1 by bolts 6 and nuts 7. The sleeves 2 are fixedly connected to the fire extinguisher body 1 by bolts 6 and nuts 7, which facilitates the replacement of the fire extinguisher body 1.
[0026] As a technical optimization solution of the present invention, the outer walls of the plurality of connecting rods 4 are sleeved with springs 8 located outside the elastic member 10 .

[0032] As a technical optimization solution of the present utility model, the material of the two sleeves 2 is iron.
[0033] In this embodiment, by setting the material of the two sleeves 2 to iron, when the nut 7 is tightened, the sleeves 2 are deformed and thus fixed on the fire extinguisher body 1.
[0034] As a technical optimization solution of the utility model, the exteriors of the two sleeves 2 are sprayed with paint.
[0035] In this embodiment, paint is sprayed on the outside of the two sleeves 2 to prevent the sleeves 2 from rusting.
[0036] The working principle and use process of the utility model are as follows: during installation, the two sleeves 2 are sequentially sleeved on the outer wall of the fire extinguisher body 1, and the two sleeves 2 are fixed to the upper and lower ends of the fire extinguisher body 1 by bolts 6 and nuts 7. The sleeves 2 are fixedly connected to the fire extinguisher body 1 by bolts 6 and nuts 7, which is convenient for replacing the fire extinguisher body 1. When the fire extinguisher body 1 is hit or dropped, the impact force acts on the elastic member 10, causing the elastic member 10 to deform, thereby buffering the impact force. After the elastic member 10 is subjected to the impact force, its two ends slide along the connecting rod 4 to the upper and lower sides respectively, and the impact force is further buffered by the spring 8, thereby preventing the fire extinguisher body 1 from exploding after being subjected to the impact force.
