The upper and lower ends of the connection block 110 and the connector body 100 are provided with straight grooves 370 for the limit shaft 390 to slide. One side of the straight groove 370 is provided with an arc groove 380 opened at the upper and lower ends of the connection block 110. The two groups of limit shafts 390 at the upper ends of the inner walls of the left shell 210 and the right shell 220 are rotatably connected with the threaded screw 3910 inside. The top of the threaded screw 3910 passes through the left shell 210 and the right shell 220 and is fixed with a knob 3920. A limiting groove 3911 matching the threaded screw 3910 is provided at the bottom of the arc groove 380, and a fixing groove 281 matching the clamping rod 280 is opened at the upper and lower ends of the inner wall of the adapter 130.

The left shell 210 and the right shell 220 drive the cross block 290 and the limit shaft 390 to move, so that the limit shaft 390 moves in the straight groove 370. When the cross block 290 slides to the inside of the half groove 291, the card shaft 2910 on one side of the cross block 290 will be synchronously inserted into the inside of the circular groove 2911, and the surface of the limit shaft 390 will fit on one side of the arc rod 320. At this time, the connector body 100 and the adapter 130 are plugged in. After the plugging is completed, the left shell 210 and the right shell 220 are rotated again to make the left shell 210 and the right shell 220 rotate with the circular shaft 230 as the center, thereby driving the circular shaft 230 rotates synchronously, so that the round shaft 230 reels the first wire rope 240, and the first wire rope 240 pulls the first inclined block 250 to move, so that the first inclined block 250 pushes the second inclined block 260 to move synchronously, and the second inclined block 260 compresses the spiral spring 330 and drives the clamping rod 280 to extend from the inside of the connecting block 110, so that the clamping rod 280 is embedded in the fixing groove 281 inside the adapter 130, thereby enhancing the fixing effect between the connector body 100 and the adapter 130, ensuring that there will be no accidental falling off during use, thereby improving the stability and reliability of the connection, and at the same time ensuring that the signal transmission between the optical fibers 120 is not disturbed, thereby improving the performance and stability of the entire communication system;

When the protective airbag 350 expands to a certain coefficient, it will extend to the side close to the optical fiber 120, thereby driving the movable annular sleeve 360 ​​to move synchronously, so that the protective airbag 350 tightly wraps the connection between the connecting block 110 and the optical fiber 120, forming a stable protective layer, avoiding loosening or bending of the optical fiber 120 connection caused by external force, ensuring that the signal transmission between the optical fibers 120 is not disturbed, thereby improving the safety of the entire optical fiber. 120 connection system, while also helping to extend the service life of the optical fiber 120 and the connecting block 110, and reducing the cost of maintenance and replacement. Finally, by turning the knob 3920, the threaded screw 3910 is driven down, and the threaded screw 3910 is inserted into the limiting groove 3911, and the fixing component 200 and the protective component 300 are stably limited. When not in use, the left shell 210 and the right shell 220 are re-covered on the outside of the connector body 100, and the opening and closing plates 420 on both sides are reset, which can effectively prevent dust and other tiny particles from entering the interior of the connector body 100. Dust and particles may contaminate its end face, resulting in a decrease in signal transmission quality or unstable connection, thereby ensuring that the connector body 100 remains clean when used next time.

[0046] Please refer to Figures 1 to 3 An optical fiber 120 is disposed on the other side of the connection block 110, and an adapter 130 is plugged into the side of the connector body 100 away from the connection block 110.

After the plugging is completed, the left shell 210 and the right shell 220 are rotated again to make the left shell 210 and the right shell 220 rotate with the circular shaft 230 as the center, thereby driving the circular shaft 230 rotates synchronously, so that the round shaft 230 reels the first wire rope 240, and the first wire rope 240 pulls the first inclined block 250 to move, so that the first inclined block 250 pushes the second inclined block 260 to move synchronously, and the second inclined block 260 compresses the spiral spring 330 and drives the clamping rod 280 to extend from the inside of the connecting block 110, so that the clamping rod 280 is embedded in the fixing groove 281 inside the adapter 130, thereby enhancing the fixing effect between the connector body 100 and the adapter 130, ensuring that there will be no accidental falling off during use, thereby improving the stability and reliability of the connection, and at the same time ensuring that the signal transmission between the optical fibers 120 is not disturbed, thereby improving the performance and stability of the entire communication system;

[0054] When the left shell 210 and the right shell 220 rotate, the limiting shaft 390 will be driven to move synchronously along the arc groove 380, so that the limiting shaft 390 squeezes the arc rod 320, and the arc rod 320 stretches the coil spring 330 and compresses the gas inside the arc tube 310, so that the gas enters the protective airbag 350 through the air pipe 340, so that the protective airbag 350 expands. When the protective airbag 350 expands to a certain coefficient, it will extend to the side close to the optical fiber 120, thereby driving the movable annular sleeve 360 ​​to move synchronously, so that the protective airbag 350 tightly wraps the connection between the connecting block 110 and the optical fiber 120, forming a stable protective layer, avoiding loosening or bending of the optical fiber 120 connection caused by external force, ensuring that the signal transmission between the optical fibers 120 is not disturbed, thereby improving the stability and performance of the entire optical fiber 120 connection system.
