Why does the Xiaomi Smart Band 8 wristband buckle easily come off?

When wearing the band, be careful not to scratch the end of the short strap (the buckle end) with hard objects to avoid accidentally touching the buckle and causing the buckle to detach. The watch strap is designed with an arc-shaped structure that imitates the wrist. If the buckle comes loose accidentally, it will not fall off automatically without external force. Just tighten the buckle in time. If the corresponding buckle hole is worn and deformed due to long-term wear, causing the buckle to be easily detached, the strap needs to be replaced in time.
