[0024] Fire is a common disaster in daily life and industrial production, posing a huge threat to people's lives and property. In order to quickly extinguish fires before they form and protect injured people, a fire prevention tool with teeth has emerged.

[0025] This type of fire-fighting tool usually has a biting tooth body, a fire-proof layer and a handle. The biting tooth body can quickly bite off burning objects such as wires, ropes, etc. The fire-proof layer in the fire-fighting tool can prevent the fire-fighting tool from spontaneous combustion and provide good heat resistance for users to use stably for a long time.

[0026] In order to ensure that the main body of the bite has good strength and service life, it is usually made of metal and provided with an anti-rust layer on the metal surface. However, if the fireproof tool is placed naked, the main body of the bite will be damaged and become brittle, and it will also easily hurt people.

[0027] To do this, please refer to Figure 1 The present application provides a biting fire prevention tool, including a handle 1, a connector 2, a biting body and a shell 4.

The housing 4 can be made of metal, such as iron, and can be treated to prevent rust. The housing 4 can be cylindrical or prismatic. The opening 42 of the housing 4 can be configured to correspond to the shape of the connecting plate to facilitate sliding between the housing 4 and the connecting plate.

[0033] The biting tooth body 3 in the present application can be accommodated in the cavity 41 of the shell 4 by sliding between the shell 4 and the connecting body 2, so that the biting tooth body can be well protected by the cavity 41 of the shell 4, avoiding the impact of foreign objects during daily placement, and also avoiding people or animals from accidentally contacting the biting teeth 33 and getting injured, thereby improving the safety of the fire-fighting tool; at the same time, the fixed setting of the shell 4 helps to set the fire-fighting tool at a fixed point, and facilitates the search for fire-fighting tools. When in use, the biting tooth body can be directly pulled out of the shell 4 by holding the handle 1, so as to facilitate more convenient and quick response to sudden dangers.

[0034] Please refer to Figure 1 In some examples, the connector 2 is provided with a sliding step 21, which is located at the end of the connector 2 away from the handle 1. The sliding step 21 is slidably connected to the housing 4, and the end surface of the sliding step 21 near the handle 1 abuts against the housing 4. The sliding step 21 allows smooth sliding between the housing 4 and the connector 2, while also limiting the maximum sliding distance between the housing 4 and the connector 2, thereby preventing the tooth body from contacting the inner wall of the housing 4 and protecting the tooth body.

[0035] In some examples, the sliding step 21 can be formed by performing subtractive processing such as cutting or grinding on the edge of the connector 2 , and a gap can be provided between the sliding step 21 and the inner wall of the housing 4 .

[0036] Please refer to Figure 1In some examples, the housing 4 further includes a flexible body 43, which is disposed within the housing 4 and located at the opening 42 of the housing 4. The flexible body 43 abuts against the sliding step 21.
