An anti-loosening component 7 is installed in the mounting groove 4, and the two ends of the anti-loosening component 7 extend into the interior of the two arc-shaped grooves 5 respectively. The anti-loosening component 7 includes an adjusting shaft 8, which is located in the middle of the mounting groove 4. A support bearing 9 is rotatably mounted on the bottom of the adjusting shaft 8 and is fixedly mounted in the middle of the bottom of the mounting groove 4. A positioning bearing 10 is rotatably mounted on the outside of the adjusting shaft 8 and is fixedly mounted in the middle of the top of the mounting groove 4. The top of the adjusting shaft 8 extends through and into the interior of the circular opening 3. A cross-shaped adjusting groove 11 is provided on the top of the adjusting shaft 8. An adjusting thread 20 is provided on the outside of the top of the adjusting shaft 8. A locking nut 21 is installed on the outside of the adjusting thread 20, and the bottom of the locking nut 21 contacts the top of the stud 1. An adjusting plate 12 is fixedly installed inside the mounting groove 4 and outside the adjusting shaft 8. A connecting shaft 13 is symmetrically fixedly installed on the top of the adjusting plate 12. A movable bar 14 is rotatably installed on the connecting shaft 13. A movable shaft 15 is rotatably installed at the end of the movable bar 14 away from the connecting shaft 13. An arc-shaped movable frame 16 is fixedly installed at the end of the movable shaft 15 away from the movable bar 14. Arc-shaped airbags 17 are symmetrically fixedly installed on the inner wall of the mounting groove 4. The two arc-shaped movable frames 16 are respectively in contact with the outer side of the two arc-shaped airbags 17. A fastening airbag 18 is fixedly installed inside the two arc-shaped grooves 5. An air hole 19 is opened in the middle of the outer side of the fastening airbag 18. The air hole 19 is horizontally aligned with the connecting hole 6. The arc-shaped airbag 17 communicates with the interior of the fastening airbag 18 through the connecting hole 6 and the air hole 19. A connecting block 22 is fixedly installed on the top of the arc-shaped movable frame 16, and a positioning slide sleeve 23 is fixedly installed on the top of the connecting block 22. A positioning slide rod 24 is slidably installed inside the positioning slide sleeve 23, and one end of the positioning slide rod 24 is fixedly connected to the inner wall of the mounting groove 4. A circular limit block 25 is fixedly installed on the other end of the positioning slide rod 24. Positioning sliders 26 are symmetrically fixedly installed on the inner wall of the positioning slide sleeve 23. Positioning grooves 27 are symmetrically opened on the outer side of the positioning slide rod 24, and the positioning sliders 26 are slidably installed inside the positioning grooves 27.

[0015] In use, the interaction of the hexagonal nut 2, circular opening 3, stud 1, arc groove 5, connecting hole 6, mounting groove 4, and anti-loosening component 7 ensures that the high-strength alloy screw can prevent loosening during use, improving its fastening performance and thus facilitating better practicality. Furthermore, the interaction of the connecting block 22, positioning sleeve 23, positioning slide rod 24, circular limit block 25, positioning groove 27, and positioning slider 26 ensures that the arc-shaped movable frame 16 can achieve better stability during movement, thereby ensuring that the anti-loosening component 7 can work stably.

[0016] During operation, rotating the hexagonal nut 2 causes the stud 1 to rotate and enter the preset fixing hole. After the bottom of the hexagonal nut 2 contacts the top of the preset fixing hole, stop rotating the hexagonal nut 2. Then, insert a Phillips head screwdriver into the Phillips head adjustment slot 11 to keep the adjustment shaft 8 stationary. Then, loosen the locking nut 21 to release the fixing of the adjustment shaft 8. Then, rotate the adjustment shaft 8, which drives the adjustment plate 12 to rotate. The adjustment plate 12 drives the connecting shaft 13 to move. The connecting shaft 13 drives the movable bar 14 to move. The movable bar 14 pushes the arc-shaped movable frame 16 to move through the movable shaft 15. The arc-shaped movable frame 16 drives the connecting block 22 to move. The connecting block 22 drives the positioning sleeve 23 to slide on the outside of the positioning slide rod 24. The positioning sleeve 23... The movable positioning slider 26 slides inside the positioning groove 27, ensuring better stability of the arc-shaped movable frame 16 during movement. Simultaneously, the movement of the arc-shaped movable frame 16 compresses the arc-shaped airbag 17. Under this compression, air inside the arc-shaped airbag 17 enters the fastening airbag 18 through the connecting hole 6 and the air hole 19, causing the fastening airbag 18 to expand. The expanded fastening airbag 18 then comes into close contact with the inner wall of the preset fixing hole, increasing the friction between the outer side of the stud 1 and the preset fixing hole, preventing the stud 1 from loosening. Then, the rotation of the adjusting shaft 8 stops, and the locking nut 21 is tightened to reposition the adjusting shaft 8. This ensures that the high-strength alloy screw achieves an anti-loosening effect during use, improving its fastening performance and facilitating better practicality.
