AI Technical Summary

Technical Problem

The existing watch strap buckle mechanism cannot adjust the distance between the two watch straps, resulting in it being unable to fit wrists of different sizes and having poor versatility.

Method used

A watch strap buckle device was designed. Through the combination of a telescopic plate, a connecting seat, a bottom bracket, and a base, the adjustable distance of the watch strap is achieved. The cooperation of the toothed parts and the safety buckle allows the telescopic plate to engage or disengage at different positions. The base can be stacked to adjust the strap spacing to accommodate different wrist sizes.

Benefits of technology

The watch strap buckle device has been improved in terms of versatility, making it suitable for wrists of different sizes and ensuring a stable connection and adjustment of the watch strap.
