[0031] Reference Figure 1 and Figure 2The utility model provides an embodiment: a high-strength rivet, including a mounting plate 1, the bottom of the mounting plate 1 is rotatably connected to a rotating plate 2 4 of a ring array, the bottom of the rotating plate 2 4 is rotatably connected to a rotating plate 1 3, the bottom of the rotating plate 1 3 is rotatably connected to a top head 2, the center of the top head 2 is rotatably connected to a limiting block 7, the top of the limiting block 7 is fixedly connected to a connecting column 10, the top of the connecting column 10 is fixedly connected to a threaded column 8, a threaded opening 11 is opened in the center of the mounting plate 1, the threaded column 8 is threadedly connected to the threaded opening 11, a stretching assembly is arranged inside the mounting plate 1, the stretching assembly includes a driving column 5, the outer wall of the driving column 5 is slidably connected to the inside of the connecting column 10, and the outer wall of the driving column 5 is slidably connected to the inside of the threaded column 8;

[0032] Specifically, the rivet adopts an aluminum alloy structure, which can achieve the effect of light weight and high strength. When the rivet is used, first, the handle 9 is used to pull the driving column 5, and then the driving column 5 pulls the threaded column 8. Then, the threaded column 8 is connected with the connecting column 10, and the connecting column 10 lifts the head 2 through its bottom limit block 7. This step is to allow the rotating plate 1 3 and the rotating plate 2 4 to be folded and unfolded. With the cooperation of the connecting column 10 and the mounting plate 1, the rivet is fixed. Finally, the driving column 5 drives the threaded column 8 to rotate. This step is to allow the threaded column 8 to rotate and tighten inside the threaded port 11, so that the rivet is further fixed.

[0033] Reference Figure 1 and Figure 3 , a slide rod 16 is slidably connected inside the driving column 5, one end of the slide rod 16 is fixedly connected to a button 6, both sides of the outer wall of the driving column 5 are fixedly connected to handles 9, one side of the outer wall of the slide rod 16 is fixedly connected to a sliding ring 18, a slide groove 17 is provided on one side of the driving column 5, the sliding ring 18 is slidably connected inside the slide groove 17, a spring 19 is sleeved on the outer wall of the slide rod 16, one end of the spring 19 is fixedly connected to one side of the outer wall of the sliding ring 18, and the other end of the spring 19 is fixedly connected to the driving column 5, one end of the slide rod 16 is fixedly connected to a conical block 12, the outer wall of the conical block 12 is slidably connected to the driving column 5, a slide groove 14 is provided on both sides of the driving column 5, and a card ball 15 is slidably connected on both sides of the outer wall of the conical block 12, and the outer wall of the card ball 15 is slidably connected inside the slide groove 14, and a card groove 13 is provided on both sides of the connecting column 10, and the outer wall of the card ball 15 is slidably connected inside the card groove 13;

[0034] Specifically, when the driving column 5 needs to be removed, only the button 6 needs to be pressed, and the button 6 will push the slide rod 16 forward. During the movement of the slide rod 16, the resistance generated by the spring 19 needs to be overcome. After overcoming the resistance, the conical block 12 will be pressed down, and the card ball 15 will lose the constraint of the conical block 12. Since the card ball 15 is no longer restricted, it will slide out of the slide groove 14 opened on the inner wall of the connecting column 10. During the sliding out process, the card ball 15 will slide out of the card groove 13, causing the card ball 15 to retract into the slide groove 14, and then the driving column 5 can be removed from the connecting column 10.

[0035] When the rivet is fixed, the driving column 5 can be pulled by the handle 9, and the driving column 5 can pull the threaded column 8 and the connecting column 10, and the connecting column 10 can lift the top 2 through the limit block 7 at the bottom of the connecting column 10, so that the rotating plate 1 3 and the rotating plate 2 4 are folded and unfolded, so as to cooperate with the mounting plate 1 to fix the rivet, and then the threaded column 8 is driven to rotate by the driving column 5, and the threaded column 8 can be rotated and tightened inside the threaded mouth 11, so that the rivet can be further fixed. When the driving column 5 is removed from the inside of the connecting column 10, the button 6 can be pressed, and the button 6 pushes the sliding rod 16 to overcome the force of the spring 19 to press the conical block 12 down, and the card ball 15 will lose the restriction of the conical block 12, thereby sliding out of the card slot 13 opened on the inner wall of the connecting column 10 and retracting into the slide slot 1 14, so that the driving column 5 can be removed. This usage method does not require the device to be caught, so it can be easily used in various different usage scenarios.
