[0020] Appendix Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] See attached document Figures 1-4 A rotary watch clasp, used in conjunction with a first watch strap 1 and a second watch strap 2. The second watch strap 2 has several strap holes, each containing a locking pin 3. A connecting ring 4 is fixedly installed at one end of the first watch strap 1 near the second watch strap 2. A limiting component is installed on the connecting ring 4, and a locking component is provided within the limiting component, engaging with the locking pin 3. The limiting component includes a mounting pin 5, with a second placement cavity 18 at its top. A hollow pin 6 is fixedly connected to the inner wall of the second placement cavity 18. A [missing information - likely a device or structure] is positioned above the second placement cavity 18. The compression spring 12 and the knob 13 have a first placement cavity 17 at their bottom ends. The other end of the compression spring 12 abuts against the inner wall of the first placement cavity 17. The snap-fit ​​assembly includes a rotating rod 7, a fixing block 8, and a stop block 9. The rotating rod 7 is located inside the first placement cavity 17. The top end of the rotating rod 7 is fixedly connected to the inner wall of the first placement cavity 17. The rotating rod 7 passes through the bottom ends of the hollow column 6 and the mounting column 5 and extends to the outside. The bottom end of the rotating rod 7 is fixedly connected to the fixing block 8. The periphery of the fixing block 8 is fixedly connected to the stop block 9. There are two stop blocks 9, and the two stop blocks 9 are symmetrically arranged.

[0022] In this embodiment, the compression spring 12 abuts against the inner wall of the first placement cavity 17 so that the knob 13 will not rotate when it is turned.

[0023] Specifically, the bottom surface of the snap-fit ​​post 3 is provided with a snap-fit ​​cavity 16, the top surface of the snap-fit ​​post 3 is provided with a first clearance groove 10, and two second clearance grooves 11 are provided on the left and right sides of the first clearance groove 10. The second clearance grooves 11 are connected to the first clearance groove 10, and the first clearance groove 10 and the second clearance grooves 11 are connected to the snap-fit ​​cavity 16.

[0024] In this embodiment, the size of the first clearance groove 10 is larger than that of the fixing block 8, and the size of the second clearance groove 1 is larger than that of the stop block 9, so that personnel can move the fixing block 8 and the stop block 9 into the snap-fit ​​cavity.

[0025] Specifically, the rotating rod 7 passes through the first clearance groove 10 and extends into the snap-fit ​​cavity 16. The fixing block 8 and the stop block 9 are located in the snap-fit ​​cavity 16, and the top surface of the stop block 9 abuts against the top surface of the inner wall of the snap-fit ​​cavity 16.

[0026] Specifically, a third clearance groove 14 is provided on the periphery of the knob 13, and the third clearance groove 14 is slidably connected to the inner wall of the second placement cavity 18.

[0027] In this embodiment, when the knob 13 moves downward, it slides into the second placement cavity 18.

[0028] Specifically, a limiting ring 19 is fixedly connected to the periphery of the first watch strap 1, and one end of the second watch strap 2 passes through the limiting ring 19 and extends to the outside.

[0029] In this implementation scheme, the limiting ring 19 can further limit the second watch strap 2 to prevent the second watch strap 2 from being too long and affecting the wearer's ability to wear it.

[0030] The working principle and usage process of this utility model are as follows: When a person wants to wear it, they first press down on the knob 13, causing it to enter the second placement cavity 18. The knob 13 compresses the compression spring 12, at which point the knob 13 drives the rotating rod 7 to move downwards. The rotating rod 7 slides downwards within the hollow column 6, and the downward movement of the rotating rod 7 drives the fixing block 8 and the stop block 9 to move downwards. The fixing block 8 and the stop block 9 enter the snap-fit ​​cavity 16 from the first clearance groove 10 and the second clearance groove 11. At this time, the person rotates the knob 13, which drives the rotating rod 7 to rotate. 7 drives the fixing block 8 and the stop block 9 to rotate in the locking cavity 16. When the knob 13 rotates 90 degrees, the person releases the knob 13. The compressed spring 12 rebounds and drives the knob 13 to move upward. The upward movement of the knob 13 drives the rotating rod 7 to move upward. The upward movement of the rotating rod 7 drives the fixing block 8 and the stop block 9 to move upward. At this time, the top surface of the stop block 9 abuts against the inner wall of the locking cavity 16. The knob 13 and the locking post 3 are limited by the rotating rod 7, the fixing block 8, and the stop block 9, thus completing the connection. The person inserts the second watch strap 2 into the limiting ring 19 to complete the wearing.

[0031] When a person wants to remove the watch, they first press down on knob 13, causing it to enter the second placement cavity 18. Knob 13 compresses the compression spring 12, at which point knob 13 drives the rotating rod 7 to move downwards. The rotating rod 7 slides downwards within the hollow column 6, and the downward movement of the rotating rod 7 drives the fixing block 8 and the stop block 9 to move downwards within the locking cavity 16. At this point, the top surface of the stop block 9 no longer abuts against the inner wall of the locking cavity 16. The person then rotates knob 13, which in turn rotates the rotating rod 7. The fixed block 8 and the stop block 9 rotate within the locking cavity 16. When the knob 13 rotates 90 degrees, the operator releases the knob 13. The compressed spring 12 rebounds, causing the knob 13 to move upward. The upward movement of the knob 13 causes the rotating rod 7 to move upward, which in turn causes the fixed block 8 and the stop block 9 to move upward and out of the locking cavity 16. This removes the limiting position of the knob 13 and the locking post 3. The operator then pulls the second watch strap 2 out of the limiting ring 19, at which point the operator can remove the watch.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
