DETAILED DESCRIPTION

[0022] Below, the utility model is further described in combination with the drawings and specific embodiments:

[0023] Embodiment 1

[0024] Reference Figures 1 to 5 Embodiment 1 is described, including first connecting column 5, first connecting column 5 rotatory connection connecting ring 1, connecting ring 1 another side rotatory connection second connecting column 12, second connecting column 12 passes through second fixed plate 17, second fixed plate 17 connects dismounting device, second fixed plate 17 is equipped with connecting device, the first shell 4 of dismounting device one side fixed connection second fixed plate 17, first shell 4 inner wall fixed connection first sliding rail 10, first sliding rail 10 sliding connection first sliding block 11, first sliding block 11 lower end fixed connection second connecting column 12, second connecting column 12 lower end fixed connection second sliding block 13, second sliding block 13 sliding connection second sliding rail 14, second sliding rail 14 lower end fixed connection first shell 4 inner wall, second connecting column 12 one end fixed connection first spring 15, first spring 15 another end fixed connection third connecting column 16, first shell 4 outer wall is equipped with upper ring 2, upper ring 2 is connected through screw 6 lower ring 3, lower ring 3 lower end fixed connection first fixed plate 7, first fixed plate 7 is provided with snap ring 8, snap ring 8 lower end sleeve joint decorative disc 9;

[0025] In this embodiment, the screw 6 is unscrewed, and the upper ring 2 and the lower ring 3 are disassembled to replace the decorative disc 9. Pulling the second connecting column 12 moves the first sliding block 11 and the second sliding block 13 along the first sliding rail 10 and the second sliding rail 14, respectively. After loosening, the first spring 15 pulls the second connecting column 12 back to its original position, thereby adjusting the length of the bracelet.

[0026] Example 2

[0027] Reference Figures 1 to 5 To illustrate Example 2, this embodiment further explains Example 1, including a connecting device. The fourth connecting column 18 on the connecting device is fixedly connected to the third fixed plate 19 on one side. The third fixed plate 19 is fixedly connected to the second spring 25 on the other side. The second spring 25 is fixedly connected to the piston 24 on the other side. The third fixed plate 19 is fixedly connected to the second housing 20 on one side. The second housing 20 is provided with a sliding groove 22. The second housing 20 is fixedly connected to the fourth fixed plate 26 on the other end. The fourth fixed plate 26 is provided with the movable rod 23 inside. The movable rod 23 is fixedly connected to the pull rod 21 on the upper end.

[0028] In this embodiment, the movable rod 23 is placed into the second housing 20, and the pull rod 21 is pulled. The pull rod 21 moves along the sliding groove 22, and the movable rod 23 moves along with the pull rod 21. The movable rod 23 drives the piston 24 to move, and the piston 24 compresses the spring. When the pull rod 21 reaches the designated position, the pull rod 21 is loosened. The spring pushes the piston 24, and the piston 24 pushes the movable rod 23, which drives the pull rod 21, thereby realizing the wearing function.

[0029] In specific applications, unscrewing the screw 6 can disassemble the upper ring 2 and the lower ring 3, thereby conveniently replacing the decorative disc 9 to meet different aesthetic needs or occasion requirements. Pulling the second connecting column 12 can move the first sliding block 11 and the second sliding block 13 along their respective first sliding rail 10 and second sliding rail 14. This function allows users to adjust the length of the bracelet according to the wrist size. After loosening, the first spring 15 will automatically pull the second connecting column 12 back to its original position, ensuring that the adjusted bracelet maintains the best wearing comfort and aesthetics. Placing the movable rod 23 into the second housing 20 and pulling the pull rod 21 will move the pull rod 21 along the sliding groove 22 while driving the movable rod 23 to move. The movement of the movable rod 23 will further drive the piston 24, causing the piston 24 to compress the second spring 25. When the pull rod 21 reaches the designated position, the pull rod 21 is loosened. At this time, the second spring 25 will generate a reverse thrust due to compression, pushing the piston 24 back to its original position. The piston 24 pushes the movable rod 23, which drives the pull rod 21 back to the locking position, realizing a safe and reliable wearing function. This design not only simplifies the wearing process of the bracelet but also enhances the convenience and stability of use, making the bracelet easy to wear, adjust the length, and replace decorative elements.
