[0053] In this embodiment, when the first buckle 1 is connected with the second buckle 2, the third magnetic member 24 attracts the fourth magnetic member 35, so that the slide buckle 3 moves towards the first buckle 1, that is, the whole watchband is shorter when worn, so that the watchband closely fits the user's arm, which can effectively improve the PPG monitoring function; when the first buckle 1 is separated from the second buckle 2, the first magnetic member 14 repels the fourth magnetic member 35, so that the slide buckle 3 moves away from the first buckle 1, that is, the whole watchband is longer after being taken off, which can facilitate the user to wear and operate, and improve the wearing experience.

[0054] In one embodiment, referring to the drawings attached Figure 3 , In one embodiment, referring to the drawings attached Figure 4 , the magnetic attraction force of the first magnetic member 14 and the second magnetic member 23 is greater than the magnetic attraction force of the third magnetic member 24 and the fourth magnetic member 35, which is greater than the repulsion force of the first magnetic member 14 and the fourth magnetic member 35. By setting the magnetic attraction force of the first magnetic member 14 and the second magnetic member 23 to be larger, the first buckle 1 and the second buckle 2 can be automatically magnetically attracted and aligned when connected; by setting the magnetic attraction force of the third magnetic member 24 and the fourth magnetic member 35 to be greater than the repulsion force of the first magnetic member 14 and the fourth magnetic member 35, when worn, the slide buckle 3 can overcome the repulsion force of the first magnetic member 14 and the fourth magnetic member 35 under the action of the magnetic attraction force of the third magnetic member 24 and the fourth magnetic member 35, and move towards the first buckle 1, that is, the whole watchband is shortened.

When the first watch buckle 1 and the second watch buckle 2 are separated, the fourth magnetic member 35 is away from the third magnetic member 24, the magnetic attraction force of the fourth magnetic member 35 and the third magnetic member 24 disappears, and the fourth magnetic member 35 is only subjected to the repulsion force of the first magnetic member 14, so that the slide buckle 3 moves away from the first watch buckle 1, that is, the slide buckle 3 is elongated.
