Two second notches 4 are provided on both sides of the other end of each strap link body 1. Connecting ears 5 are provided inside each of the two second notches 4. Rotating grooves 6 that mate with the fixing shafts 3 are provided on each of the two connecting ears 5. A first groove 7 is provided in the middle of the other end of each strap link body 1. A second groove 8 is provided on the side end of the first groove 7. Two first circular grooves 9 communicating with the second grooves 8 are provided on the side ends of each of the two second notches 4. A first circular rod 10 is slidably and sealed inside each of the two first circular grooves 9. The connecting ears 5 are fixedly connected to the corresponding two first circular rods 10. A sealing plate 11 is sealed and installed inside the first groove 7. A fixing mechanism for fixing the two connecting ears 5 is connected to the sealing plate 11.

[0032] Specifically, the two watchband links 1 are connected by inserting two fixed shafts 3 into the slots 6 on the two connecting ears 5 on the adjacent watchband link body 1. By pulling the two connecting ears 5 to the sides, the connecting ears 5 are separated from the fixed shafts 3, thus making it easier to separate the two watchband link bodies 1. This avoids disassembling a large number of small parts and prevents the loss of small parts from affecting the assembly of the watchband.

[0033] Please see Figures 1-4The fixing mechanism includes a second round rod 12 and a cylinder 13. Two sliding plates 14 are slidably disposed inside the second groove 8.

[0036] Specifically, the first sealing ring 27 ensures the sealing between the first round rod 10 and the watch band link body 1, the second sealing ring 29 ensures the sealing between the second round rod 12 and the sealing plate 11, and the sealing gasket 25 ensures the sealing between the sealing plate 11 and the watch band link body 1. This prevents water and sweat from entering the interior of the second groove 8 and avoids water and sweat from contacting the internal structure of the second groove 8, making it easier to clean and maintain the exterior of the watch band link body 1.

[0037] In summary, when using the overall equipment:

[0038] When assembling multiple watchband link bodies 1, pull the throttle 21. The throttle 21 moves the second round rod 12 and the cylinder 13 to the position closest to the sealing plate 11. At this time, the throttle 21 moves to one side of the four positioning blocks 22, and the retaining strip 18 separates from the two retaining plates 15. Then, rotate the throttle 21, the second round rod 12, and the cylinder 13 by 90°. At this time, the two retaining strips 18 are located on the left and right sides of the cylinder 13, respectively. Then, pull the two connecting ears 5 to move to both sides. Then, insert the adjacent watchband link body 1 into the middle of the two connecting ears 5, and align the fixing shaft 3 with the position of the annular groove. Then, move the two connecting ears 5 to the middle, and insert the fixing shaft 3 into the corresponding throttle. Inside the slot 6, pull the handle 21. The handle 21 moves the second round rod 12 and the cylinder 13 to the position closest to the sealing plate 11. At this time, the locking strip 18 separates from the two locking plates 15. Then rotate the handle 21, the second round rod 12 and the cylinder 13 and rotate 90°. At this time, the locking strip 18 corresponds to the locking groove 17 on the two locking plates 15. Release the handle 21. The compression spring 20 pushes the cylinder 13, the second round rod 12 and the handle 21 to move, so that the two locking strips 18 are inserted into the corresponding locking groove 17, thereby fixing the two slide plates 14, the four first round rods 10 and the two connecting ears 5, so that the two adjacent watch strap links 1 are connected together.
