Technical Field

The utility model belongs to the technical field of glasses, and particularly relates to a screwless temple connection structure with self-resetting function.

Background Art

Glasses are used more and more widely in life as vision correction tools and shading tools. Glasses frames are mainly used to support the lenses and act as a support for the glasses when worn on the eyes. Glasses frames are mainly composed of a frame and two temples. The frame is provided with a stud, and the temples are connected to the stud by hinges. The two temples are arranged on both sides of the frame and can be hooked on the ears of the wearer to fix them when worn.
