[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: A firearm RFID radio frequency identification device includes a sleeve 1. A barrel 2 is slidably connected inside the sleeve 1. A grip 3 is fixedly connected to the bottom of the sleeve 1. A trigger 4 is fixedly connected to the outer wall of the grip 3. A protective cover 5 is arranged inside the sleeve 1. A chip 8 is arranged at the bottom of the protective cover 5. Antennas 9 are fixedly connected to both sides of the chip 8. A fixing plate 13 is arranged at the bottom of the chip 8. A connecting column 14 is fixedly connected to the bottom of the fixing plate 13. The connecting column 14 is made of high-strength stainless steel and its surface is finely polished, smooth and firm. A round table fixing block 15 is fixedly connected to the bottom of the connecting column 14. The round table fixing block 15 is made of hard aluminum alloy and its surface is anodized, which not only has good wear resistance but also can effectively prevent corrosion. A plurality of square clamping blocks 16 are arranged on the outer wall of the round table fixing block 15. The square clamping blocks 16 are made of engineering plastics with good toughness, having certain elasticity and strength. One side of each square clamping block 16 is fixedly connected to a telescopic column 17. The telescopic column 17 is fixedly connected inside the sleeve 1. A first spring 18 is fixedly connected to the outer wall of the telescopic column 17. The first spring 18 is fixedly connected to the outer wall of the square clamping block 16. A protective component is arranged on the outer wall of the chip 8 for protecting the chip 8. A plurality of screws 6 are threadedly connected inside the protective cover 5. The screws 6 are threadedly connected inside the fixing plate 13. Threaded tubes 7 are threadedly connected to the bottoms of the screws 6. The screws 6 are made of high-strength alloy steel with fine threads and can closely cooperate with the threaded tubes 7. The threaded tubes 7 are fixedly connected inside the sleeve 1.

[0034] Specifically, during the installation of the device, first, the connecting column 14 at the bottom of the chip 8 drives the frustum fixing block 15 to move to the outer wall of the square clamping block 16. The outer wall of the frustum fixing block 15 is an arc-shaped inclined surface, which can squeeze and contract the square clamping block 16 during the movement. When the arc-shaped inclined surface of the frustum fixing block 15 squeezes the square clamping block 16, it will drive the telescopic column 17 and the first spring 18 to contract. The contraction movement of the telescopic column 17 is used to limit the compression of the first spring 18, which can effectively prevent the first spring 18 from bending, thereby preventing the situation where the square clamping block 16 deviates from its movement trajectory. When the top of the frustum fixing block 15 passes through the square clamping block 16, the rebounding force of the first spring 18 will drive the acute-angle groove on one side of the square clamping block 16 to position and fix the top and inclined surface of the frustum fixing block 15. And the screw 6 is rotated threadedly into the threaded tube 7, which enhances the stability of the chip 8 and ensures that the chip 8 will not shift during use.

[0035] Refer to Figure 2 , Figure 3 and Figure 5 , the protection component includes a rubber protection sleeve 10, which is fixedly connected to the side wall of the chip 8. The rubber protection sleeve 10 is made of high-quality natural rubber and has good elasticity and toughness. Its thickness is moderate and it can closely fit on the side of the chip 8, providing the first buffer defense line for the chip. A first sponge protection plate 11 is fixedly connected to the top of the chip 8, and the first sponge protection plate 11 is fixedly connected inside the protection cover 5. A second sponge protection plate 12 is fixedly connected to the bottom of the chip 8. The first sponge protection plate 11 and the second sponge protection plate 12 are made of high-density sponge material, with soft and elastic texture. This sponge material has good energy absorption performance and can quickly deform and absorb a large amount of impact force when an impact occurs. The second sponge protection plate 12 is fixedly connected inside the fixing plate 13. A plurality of connecting plates 19 are fixedly connected to the bottom of the fixing plate 13. The connecting plates 19 are made of stainless steel material with a smooth surface, which can reduce the frictional resistance during movement. Limit plates 20 are fixedly connected to both sides of the connecting plates 19. The outer walls of the two limit plates 20 are slidably connected to a fixed base 22. The limit plates 20 are made of high-strength plastic and have certain rigidity and wear resistance. Its shape matches the inner wall of the fixed base 22 and can maintain a stable movement trajectory during sliding. The fixed base 22 is fixedly connected inside the sleeve 1. Second springs 21 are fixedly connected to the bottoms of the connecting plates 19, and the second springs 21 are fixedly connected to the inner walls of the fixed bases 22.

[0036] Specifically, during the process of the chip 8 being impacted, first, the rubber protective sleeve 10 protects the side of the chip 8. When an external force impacts the side of the chip 8, the rubber protective sleeve 10 can effectively absorb and disperse the impact force, reducing the direct impact on the chip. And the sponge protection plate one 11 and the sponge protection plate two 12 protect the top and bottom of the chip 8. When the chip 8 is impacted, it drives the connecting plate 19 to move up and down through the fixing plate 13. The up and down movement of the connecting plate 19 drives the limiting plate 20 to slide on the inner wall of the fixed base 22. At the same time, the impact on the chip 8 causes the second spring 21 to generate a compression movement, thereby absorbing the impact energy and providing additional buffer protection for the chip. Using the sliding of the limiting plate 20 on the inner wall of the fixed base 22 to limit the second spring 21 can effectively prevent the second spring 21 from bending during the compression process, ensuring that it can always maintain stable elastic performance. Finally, through the coordinated action of the rubber protective sleeve 10, the sponge protection plate one 11, the sponge protection plate two 12, and the second spring 21, all-round protection of the chip 8 is achieved, effectively avoiding damage to the chip 8 during the impact process and improving the protection performance of the device.

[0037] Working principle: During the installation of the device, the connecting column 14 at the bottom of the chip 8 drives the frustum fixing block 15 to move to the outer wall of the square clamping block 16. The arc-shaped inclined surface on the outer wall of the frustum fixing block 15 squeezes and contracts the square clamping block 16, thereby driving the telescopic column 17 and the first spring 18 to contract. Using the contraction movement of the telescopic column 17 to limit the compression of the first spring 18, preventing the first spring 18 from bending, and thus avoiding the situation where the square clamping block 16 deviates from its movement trajectory. When the top of the frustum fixing block 15 passes through the square clamping block 16, the rebound force of the first spring 18 drives the acute-angle groove on one side of the square clamping block 16 to position and fix the top and inclined surface of the frustum fixing block 15, thereby achieving the fixing effect on the chip 8. And the screw 6 is rotated into the internal thread of the threaded tube 7, thereby enhancing the stability of the chip 8 and ensuring that the chip 8 does not shift during use. During the impact on the chip 8, the rubber protective sleeve 10 protects the side of the chip 8, and the sponge protection plate one 11 and the sponge protection plate two 12 protect the top and bottom of the chip 8. When the chip 8 is impacted, it drives the connecting plate 19 to move up and down through the fixing plate 13, thereby driving the limiting plate 20 to slide on the inner wall of the fixed base 22 and causing the second spring 21 to generate a compression movement. Using the sliding of the limiting plate 20 on the inner wall of the fixed base 22 to limit the second spring 21 and prevent it from bending, ultimately achieving all-round protection of the chip 8 and avoiding damage to the chip 8 during the impact process.
