The watch strap is also an important part of the watch. It not only has high requirements for appearance, but also needs to be durable, easy to wear and adjust, and suitable for wearing. At the same time, because it is easy to sweat when wearing a watch, there are also high requirements for the material of the watch strap. The more conventional watch strap structure is generally composed of middle grains and side grains. The middle grain is set in the middle and the side grains are set on both sides. Multiple middle grains and side grains are connected in series through connecting shafts to form the required watch strap.

The side of the positioning block 21 close to the positioning groove 22 penetrates the positioning groove 22 and extends to the inside thereof to rotate in contact with the inner wall of the positioning groove 22. The positioning block 21 and the positioning groove 22 are both cylindrical in shape.

[0023] The limiting disassembly and assembly mechanism 3 is arranged on the connecting mechanism 2. The limiting disassembly and assembly mechanism 3 includes a through groove 31. The through groove 31 is opened on the side of the positioning block 21 close to the edge particle 11. A connecting groove 32 that is interconnected with the through groove 31 is opened on the edge particle 11 and corresponds to the position of the through groove 31. The left and right sides of the inner wall of the through groove 31 are fixedly connected by a positioning rod 33. The surface of the positioning rod 33 is slidably connected to two moving plates 34. The side of the moving plate 34 close to the inner wall of the through groove 31 contacts the inner wall of the through groove 31. The side of the moving plate 34 close to the edge particle 11 sequentially penetrates the through groove 31 and the connecting groove 32 and extends to the connecting groove 32. The left and right sides of the movable plate 34 and the side away from the edge particle 11 are fixedly connected to the limiting blocks 35, and an annular groove 36 adapted to the limiting blocks 35 is opened on the inner wall of the positioning groove 22 and at the positions corresponding to the two limiting blocks 35. The side of the limiting block 35 close to the annular groove 36 successively penetrates the positioning groove 22 and the annular groove 36 and extends to the inside of the annular groove 36 and rotates in contact with the inner wall of the annular groove 36. The surface of the positioning rod 33 is sleeved with a buffer spring 37, and the two ends of the buffer spring 37 are respectively connected to the movable plate 34. As shown in the figure, the buffer spring 37 at this time has the force to drive the two movable plates 34 to move away from each other.

[0024] The sealing mechanism 4 is arranged on the edge particle 11. The sealing mechanism 4 includes a sealing shell 41. The sealing shell 41 is arranged on the edge particle 11 and corresponds to the position of the positioning block 21. The side of the sealing shell 41 close to the edge particle 11 is in contact with the edge particle 11. A sealing block 42 is fixedly connected to the inner wall of the sealing shell 41.

[0026] When in use, the edge particle 11 can drive the positioning block 21 to rotate in the positioning groove 22, and the limit block 35 can rotate in the annular groove 36, which will not affect the effect of the active connection between the edge particle 11 and the middle particle 1. When the edge particle 11 needs to be removed, the sealing shell 41 is pulled first, and the sealing shell 41 drives the sealing block 42 to move away from the limit block 35, so that the sealing block 42 and the connecting groove 32 are separated, and then the two pulling blocks 43 are pulled closer to each other. The pulling blocks 43 drive the moving plate 34 to move, so that the two moving plates 34 squeeze the buffer spring 37 to move, and the moving plate 34 drives the limit block 35 and the annular groove 36 to separate, so that the limit block 35 moves into the positioning groove 22, and then the edge particle 11 is pulled upward, and the edge particle 11 drives the limit block 35 and the moving plate 34 to move away from the positioning groove 22 through the positioning block 21, so that it can be pulled out of the positioning groove 22 and the edge particle 11 can be removed.
