[0002] Forest fire refers to a forest fire that loses human control, spreads and expands freely in the woodland, and causes certain harm and losses to the forest, forest ecosystem and humans. When a forest fire occurs, fire prevention tools are needed to extinguish it. Current fire prevention tools are mainly composed of a racket head and a support rod. The racket head is used to extinguish the fire. However, the length of the support rod in the fire prevention tool is mostly fixed, and it is difficult to adjust the length of the support rod according to actual conditions, which can easily cause burns to the hands during the fire fighting process. Utility Model Content
[0003] In order to overcome the above-mentioned defects, the utility model provides a bite-tooth fire-fighting tool, which solves the problem that the length of the supporting rod in the fire-fighting tool is mostly fixed, and it is difficult to adjust the length of the supporting rod according to actual conditions, which leads to the problem of easy burns to the hands during the fire-fighting process.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bite-tooth fire-fighting tool, comprising a mounting plate, a support rod is connected to one side of the mounting plate, a cover plate is rotatably connected to the support rod, a flame-retardant head is clamped in the mounting plate, a groove is provided in the cover plate, a positioning rod is rotatably connected to the support rod, an extension rod is connected to the outside of the positioning rod, two fixing blocks are connected to the outside of the support rod, a connecting plate is connected to the cover plate, a support rod is rotatably connected to the fixing block, a bolt is connected to the outside of the support rod, and a nut is externally threaded on the bolt.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0019] like Figure 1-4As shown, the utility model provides a technical solution: a bite-tooth fire prevention tool, including a mounting plate 1, a support rod 2 is connected to one side of the mounting plate 1, a cover plate 3 is rotatably connected inside the support rod 2, a flame retardant head 5 is clamped inside the mounting plate 1, a groove 10 is provided in the cover plate 3, a positioning rod 9 is rotatably connected inside the support rod 2, and an extension rod 12 is connected outside the positioning rod 9. By setting the positioning rod 9, when a thrust or a pull is applied to the extension rod 12, the extension rod 12 will rotate with the positioning rod 9 as the center, so that the positioning rod 9 plays a certain positioning role in the rotation of the extension rod 12, and avoids the extension rod 12 from getting stuck when rotating;
[0020] The flame retardant head 5 is externally connected to two L-shaped plates 8, and the mounting plate 1 is connected to two sleeve plates 6. The sleeve plates 6 are slidably connected to the limit plates 7, and the limit plates 7 are connected to the guide rods 16. By setting the sleeve plates 6, when a pulling force is applied to the limit plates 7, the limit plates 7 will slide in the sleeve plates 6, so that the sleeve plates 6 play a certain guiding role in the movement of the limit plates 7, thereby preventing the limit plates 7 from being dislocated when moving;
[0021] A fixing plate 17 is connected under the guide rod 16, and a spring 18 is connected to the outer surface of the guide rod 16. The guide rod 16 is slidably connected in the sleeve plate 6, and the fixing plate 17 is connected to the sleeve plate 6 through the spring 18. The limit plate 7 is overlapped with the L-shaped plate 8. By setting the spring 18, when the limit plate 7 slides in the sleeve plate 6, the spring 18 will be driven to deform, so that the spring 18 plays a certain supporting role in the movement of the limit plate 7. When the limit plate 7 loses resistance, it will be reset by the spring 18;
[0022] The support bar 2 is externally connected to two fixing blocks 11, the cover plate 3 is connected to a connecting plate 4, the fixing block 11 is rotatably connected to a support rod 13, the support rod 13 is externally connected to a bolt 14, and the bolt 14 is externally threadedly connected to a nut 15;
[0023] The bolt 14 is clamped in the connecting plate 4, and the nut 15 is overlapped on the fixing block 11. By setting the bolt 14 and the nut 15, when the connecting plate 4 is overlapped on the top of the fixing block 11, the bolt 14 is clamped in the connecting plate 4, and then the bolt 14 is connected to the fixing block 11 through the nut 15, so that the bolt 14 and the nut 15 can limit the position of the cover plate 3 to a certain extent, thereby preventing the cover plate 3 from loosening in the handrail 2.
[0024] The working principle of the utility model is:
[0025] When the fireproof tool is in use, a thrust can be applied to the limit plate 7, and the limit plate 7 will drive the guide rod 16 to slide in the sleeve plate 6. When the guide rod 16 moves, the fixed plate 17 below will drive the spring 18 to deform, and then the flame retardant head 5 will be clamped into the mounting plate 1. When the flame retardant head 5 is fully fitted with the mounting plate 1, the limit plate 7 is released, and the limit plate 7 is reset by the action of the spring 18. After the reset, the limit plate 7 will be clamped with the L-shaped plate 8.
[0026] When it is necessary to extinguish a fire point farther away, the nut 15 can be disengaged from the bolt 14, and then the bolt 14 can be driven to rotate around the support rod 13. When the connecting plate 4 loses resistance, it is pulled, and the cover plate 3 is disengaged from the support rod 2, and then the extension rod 12 is unfolded with the positioning rod 9. When the connecting plate 4 is snapped into the cover plate 3, the connecting plate 4 is overlapped above the fixing block 11, and the bolt 14 is inserted into the connecting plate 4 and then connected by the nut 15.
[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
