[0002] In the prior art, wrist straps are commonly used as a wearing device and are widely used in the identity recognition and information management of patients, newborns and other groups. Traditional wrist straps usually adopt an open type design, and the two ends are closed by a buckle or a latch and other connection methods to adapt to the wrist or ankle sizes of different wearers. However, this design has significant limitations, mainly in terms of wearing comfort and adjustment accuracy.

[0003] The adjustment method of traditional wrist straps usually sets a series of buckle holes at one end of the strap body and a buckle at the other end. When wearing, the buckle is buckled into the corresponding buckle hole to adapt to the outer diameter of the wrist or ankle. Although this buckle connection method similar to a belt has a certain adjustment function, the fixed spacing between the buckle holes limits the adjustment of the hole diameter of the wrist strap. This gap will cause the adjusted wrist strap to be either too loose or too tight when worn, and precise fitting cannot be achieved, especially when worn by newborns. A loose wrist strap is prone to falling off, causing difficulties in information confirmation and inconvenience of repeated wearing. A tight wrist strap may cause discomfort to the wearer and even potential blood circulation disorders, seriously affecting the wearing experience and safety.
