Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: An electric vehicle fire hook includes a plurality of connecting rods 1, which are made of metal material and can withstand large tensile and compressive forces to ensure that they will not be easily bent or broken during use. The right end of the right connecting rod 1 is fixedly connected with a facilitating operation support component. The support component includes a main grip 2, which is designed in a shape that conforms to ergonomics and is covered with anti-slip material on the surface, which can effectively prevent the operator's hand from slipping during operation and will not cause discomfort to the hand even during long-term holding. The left end of the main grip 2 is fixedly connected to the right end of the right connecting rod 1. The outside of the right connecting rod 1 is fixedly connected with a sub-handle 3. The setting of the sub-handle 3 provides the operator with more holding options and is convenient for applying force flexibly in different operation scenarios and angles. The left ends of the two right connecting rods 1 are both fixedly connected with connecting discs 4. The connecting discs 4 have a solid structure, which can ensure the stable and reliable connection between the connecting rods 1;

[0025] Both the inner sides of the connection disk 4 are provided with two sliding grooves 6. A sliding rod 7 is slidably connected inside the sliding groove 6, which reduces the resistance when the sliding rod 7 slides therein. A connection rod 8 is rotatably connected to the adjacent sides of the two sliding rods 7. The outside of the connection rod 8 is slidably connected to the inner side of the outside of the connection disk 4. This sliding connection method ensures that the connection rod 8 can move stably during operation without jamming or deviation. One side of the connection rod 8 is fixedly connected with a pressing block 9. The surface of the pressing block 9 has certain protrusions or textures to facilitate accurate pressing operation by the operator when needed. A sliding hole 10 is provided inside the sliding rod 7;

[0026] A sliding column 5 is slidably connected inside the sliding hole 10 to ensure that the sliding column 5 can slide stably therein. A locking block 11 is rotatably connected to the outside of the sliding column 5. The rotational connection method of the locking block 11 is flexible and reliable, and it can be quickly locked or unlocked when needed. The outside of the locking block 11 is slidably connected to the inner wall of the connection disk 4. A limiting plate 12 is fixedly connected to the left side of the locking block 11. The limiting plate 12 can limit the movement range of the locking block 11 to prevent its excessive movement from causing structural failure. Two moving holes 13 are provided inside the connection disk 4. The outside of the limiting plate 12 is slidably connected to the inside of the moving hole 13. This sliding connection method ensures that the limiting plate 12 can move within a specified range and plays an effective limiting role. A spring 14 is arranged inside the moving hole 13. The spring 14 has a suitable elastic coefficient and can provide stable elastic force to ensure that the locking block 11 can quickly reset when needed. One end of the spring 14 is fixedly connected to one side of the limiting plate 12;

[0027] The other end of the spring 14 is fixedly connected to the inner side of one side of the moving hole 13 and can maintain stable performance during long-term use. The right ends of the left two connecting rods 1 are both fixedly connected with limiting disks 15. Two locking holes 16 are provided on the outside of the left two connecting rods 1. The outside of the locking block 11 is slidably connected to the inside of the locking hole 16, and the cooperation with the locking block 11 is tight to ensure that the locking block 11 can slide smoothly therein to realize the reliable connection between the connecting rods 1. The outside of the two limiting disks 15 are respectively slidably connected to the inside of the right two connecting rods 1.

[0028] Refer to Figure 2 、 Figure 4 and Figure 5, at the left end of the left connecting rod 1, a rotating disk 17 is fixedly connected, ensuring its connection with the connecting rod 1 is tight and stable, capable of withstanding large torsional forces and not loosening or falling off during operation. An external rotating rod 18 is fixedly connected to the rotating disk 17. The surface of the rotating rod 18 is specially treated, having good anti-slip performance, facilitating the operator's rotation operation and effectively transmitting torque to make the rotation action smoother and more efficient. Threaded columns 19 are fixedly connected to both the left and right sides of the rotating disk 17. An adapter block 20 is threadedly connected to the external thread of the left threaded column 19. The internal thread of the adapter block 20 perfectly matches the threaded column 19, enabling a firm connection and also being easily operable when disassembly or replacement is needed;

[0029] The left end of the adapter block 20 is fixedly connected to a fire hook 21. The external thread of the right threaded column 19 is threadedly connected to the left inner part of the left connecting rod 1. This threaded connection makes the assembly and disassembly process simple and fast, and can ensure the stability and reliability of the connection. The fire hook 21 is made of alloy steel. The fire hook 21 is made of high-quality alloy steel and has undergone strict heat treatment processes, having extremely high hardness and strength, being able to easily handle various complex fire scenarios, not being easily deformed or damaged. A wear-resistant layer 22 is provided inside the connecting rod 1, which can significantly reduce the wear of the connecting rod 1 caused by friction during use, improving its service life and reliability. A heat-insulating layer 23 is provided inside the connecting rod 1, which can effectively block the transfer of heat, protecting the operator from being scalded due to the overheating of the connecting rod 1 during use, and also reducing the influence of heat on the internal structure of the connecting rod 1 to ensure the stability of its performance.

[0030] Working principle: During operation, the operator first firmly holds the main grip 2 and the sub-grip 3, thus obtaining a stable and comfortable gripping experience, providing strong support for subsequent operations. Then, press the pressing block 9. Under the pressing action of the pressing block 9, the connecting rod 8 is driven to move, and then the sliding rod 7 can smoothly slide inside the sliding groove 6.

[0031] Subsequently, under the sliding action of the connecting rod 8, the sliding column 5 is further driven to slide inside the sliding hole 10. During this process, the locking block 11 will be driven to move accordingly, and then the locking block 11 will separate from the inside of the locking hole 16.

[0032] Moreover, during this series of actions, the limiting plate 12 will also be driven to slide inside the movable hole 13, thereby squeezing the spring 14 and causing the spring 14 to be stressed. Due to the stress of the spring 14, a strong resilience will be generated. And this resilience will provide the required force for subsequent clamping and locking. Through this series of coherent and coordinated operations, the adjustment and fixation of the length of the connecting rod 1 are finally successfully achieved, being able to conveniently adapt to various different operation requirements.

[0033] When the angle and position of the poker need to be adjusted, the operator rotates the rotating rod 18. Through this rotation action, with the close cooperation between the threaded column 19 and the connecting block 20, the angle and position of the poker can be accurately adjusted to achieve precise operation.

[0034] Next, when performing the operation of replacing the poker, first firmly hold the connecting block 20, and then pull the rotating rod 18 forcefully, thereby driving the rotating disc 17 to rotate. Under the rotation of the rotating disc 17, the threaded column 19 on its left side is driven to rotate, and then the connecting block 20 moves, and finally disengages from the outside of the threaded column 19, creating convenient conditions for subsequent replacement operations.

[0035] In addition, the wear-resistant layer 22 inside the connecting rod 1 can significantly reduce the wear caused by friction between components, effectively extending the service life of the connecting rod 1. At the same time, the heat-insulating layer 23 can efficiently block heat transfer, protecting the operator from being scalded due to the over-high temperature of the connecting rod 1 during operation, and can reduce the adverse effects of heat on the internal structure of the connecting rod 1, effectively ensuring the stable performance of the poker 21.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
