Background

With the development of intelligent watches, the types of watches are more and more, functions are more and more, the watch band design of the intelligent watches continues to be the watch band design of the traditional watches, the watch needle buckle is taken as one of the watch buckles which are most common to people, the circumference of the watch band can be automatically adjusted, but the needle buckle type watch buckle has the defect of easily damaging the watch band, in order to make up the defect of the traditional needle-hole type watch band, the two-fold type watch band and the three-fold type watch band are sequentially born, the biggest progress is that a pinhole is only used as a part of the fixed watch band, the watch band is fixed by using the pinhole, the other end is the metal folding buckle, the action of taking off the watch every day is just folding buckle to play a role, the periphery of the watch band and the hole cannot be hurt, but one remarkable defect of the folding watch buckle is that a folding mechanism is complex, the watch band needs to be opened by key unlocking, the production cost is high, and the fault rate is not in line with the current market needs. In addition, the other common disadvantage of the needle-button type watch buckle and the folding watch buckle is that the watch buckle opening and closing modes of the two modes are complicated and inconvenient.

In addition, the current functions of the intelligent watch do not meet the simple functions of timing, step counting or GPS and the like, advanced functions of sleep monitoring, heart rate monitoring or blood oxygen monitoring and the like are newly added on more intelligent watches, and the realization of the functions depends on more accurately acquiring information of a user, for example, the heart rate monitoring requires that the light rays of the signals acquired by the sensor are not interfered by an external light source. Therefore, the wristwatch needs to be tightly attached to the skin, otherwise, more noise signals are introduced, and two methods for adjusting the length of the watchband in the market at present are approximately adopted, namely, a pin-buckled watchband is provided with adjusting holes at different positions on the watchband, the watchband can be adjusted to be connected with the pin buckle, the general adjusting length is 6mm, the length of the watchband is adjusted by increasing or decreasing chain links, the length of the chain links takes a single chain link as a minimum unit, the two adjusting modes can not realize continuous adjustment of the length of the watchband, the arm size of all people can not be met, and the problem of partial tightness and partial tightness can exist.
