The first connecting end 1 includes a first head link 10 and a first watch strap 11. The second connecting end 2 includes a second head link 20. Both the first head link 10 and the second head link 20 include a head link body 3. A connecting lug 30 is provided on one side of the head link body 3. A strap hole 31 is formed between the connecting lug 30 and the head link body 3. The head end of the first watch strap 11 has a first hanging ring 110 movably disposed on the connecting lug 30 of the first head link 10. The first watch strap 11 can pass through the strap hole 31. Magnets 5 are arranged side by side at equal intervals inside the first watch strap 11, and the magnetic poles of adjacent magnets 5 are arranged in opposite directions.

[0033] Its working principle is as follows: the first end link 10 and the second end link 20 are respectively installed on the lugs on both sides of the watch case. When wearing the watch, the end of the first strap 11 can be passed through the strap hole 31 of the second end link 20 and the first strap 11 can be tightened. The excess length of the first strap 11 can be overlapped. Double or triple overlap can be performed according to the excess length of the first strap 11. Since magnets 5 are arranged in parallel at equal intervals inside the first strap 11 and the magnetic poles of adjacent magnets 5 are arranged in opposite directions, the corresponding magnets 5 at the overlapping part of the first strap 11 can attract each other, thereby keeping the strap in a tight state. There is no need for cumbersome operation, making it easier and more convenient to use, with low maintenance requirements and high durability.

[0034] Example 1, as shown in the appendix Figure 2 , 3 As shown, the first watch strap 11 is movably disposed in the strap hole 31 of the second end piece 20. (The attached text appears to be incomplete and requires further context.) Figure 2 In the double-layered state of the first watch band 11, two magnets 5 overlap at corresponding positions of the overlapping portion of the first watch band 11, with the polarities of the two overlapping magnets 5 arranged in opposite directions to achieve positioning after the first watch band 11 is double-layered; (See attached image) Figure 3 The first watchband 11 is in a three-layer overlapping state. Three magnets 5 at corresponding positions of the overlapping portions of the first watchband 11 overlap, with the polarities of the three overlapping magnets 5 arranged in reverse order to achieve positioning after the first watchband 11 is stacked in three layers. This type of second connecting end 2 has no watchband, making it suitable for people with smaller wrists.

[0035] Example 2, as shown in the appendix Figure 4 , 5 As shown, the second connecting end 2 also includes a second watch strap 21 and a pull-back ring 22. The two ends of the second watch strap 21 are respectively provided with a second loop 210 and a third loop 211. The second loop 210 is movably disposed on the connecting lug 30 of the second end piece 20. The pull-back ring 22 includes a U-shaped loop 220 and a gantry-shaped connecting part 221 connecting the middle of the two sides of the U-shaped loop 220. The U-shaped loop 220 includes a first connecting rod 220a and a second connecting rod 220b. The third loop 211 is movably disposed on the first connecting rod 220a. The tail end of the first watch strap 11 passes between the gantry-shaped connecting part 221 and the second connecting rod 220b. (The attached text is incomplete and requires further context.) Figure 4 In the double-layered state of the first watch band 11, two magnets 5 overlap at corresponding positions of the overlapping portion of the first watch band 11, with the polarities of the two overlapping magnets 5 arranged in opposite directions to achieve positioning after the first watch band 11 is double-layered; (See attached image) Figure 5The first watchband 11 is in a three-layer overlapping state, with three magnets 5 overlapping at corresponding positions in the overlapping portion of the first watchband 11. The polarities of the three overlapping magnets 5 are arranged in reverse order to achieve positioning after the first watchband 11 is three layers overlapping. This type of second connecting end 2 has a second watchband 21, which is suitable for people with larger wrists.

[0036] Based on the above embodiments, the first connecting end 1 further includes an anti-detachment tail piece 4, which is fixedly connected to the tail end of the first watch strap 11. The anti-detachment tail piece 4 cannot pass through the gap between the gantry-type connecting part 221 and the second connecting rod 220b, preventing the tail end of the first watch strap 11 from detaching from the return ring 22. This eliminates the need for frequent piercing operations of the first watch strap 11 onto the return ring 22, making it more convenient to use.

[0037] Based on the above embodiments, one side of the anti-detachment tail piece 4 is provided with a connecting groove 40 that matches the tail end of the first watch strap 11, and the tail end of the first watch strap 11 is riveted into the connecting groove 40. After the tail end of the first watch strap 11 passes through the gap between the gantry-type connecting part 221 and the second connecting rod 220b, the tail end of the first watch strap 11 is then riveted into the connecting groove 40, which can prevent the tail end of the first watch strap 11 from detaching from the pull ring 22.

[0038] Based on the above embodiments, both the first headpiece 10 and the second headpiece 20 further include a spring ear assembly 32. The spring ear assembly 32 includes a button 33, a limiting plate 34, a return spring 35, a first pin slider 36, and a second pin slider 37. The headpiece body 3 has an internal movable cavity 300. The first pin slider 36 and the second pin slider 37 are symmetrically arranged in the movable cavity 300 and can move within the movable cavity 300. The first pin slider 36 and the second pin slider 37 each include a slider 360, a connecting part 361 connected to one end of the slider 360, and a pin 362 connected to the outer end face of the connecting part 361. Both sides of the headpiece body 3 have through-holes 301 communicating with the movable cavity 300. The pin 362 is movably disposed in the through-holes 301. The two ends of the return spring 35 abut against the... Between the inner end faces of the two connecting parts 361, the outer side of the slider 360 is provided with a first inclined surface 360a. The bottom of the headstock body 3 is provided with a receiving groove 302 that matches the limiting plate 34. The receiving groove 302 is connected to the movable cavity 300. The limiting plate 34 is detachably connected to the receiving groove 302. A through hole 340 that matches the button 33 is provided through the limiting plate 34. Limiting parts 330 are symmetrically provided on both sides of the bottom of the button 33. The button 33 is movably disposed in the through hole 340. A second inclined surface 331 that matches the first inclined surface 360a is symmetrically provided on the bottom of the button 33. The second inclined surface 331 abuts against the first inclined surface 360a. A plurality of first arc-shaped ribs 360b are arranged in parallel on the first inclined surface 360a. A plurality of second arc-shaped ribs 363 are arranged in parallel on the bottom of the slider 360.
