Further, the spring assembly comprises a spring part, a spring shaft and a fixed shaft, wherein the spring shaft comprises a rod piece and a connecting part, the rod piece penetrates through the fixed bearing frame to be connected with the spring part, and the fixed shaft is connected with the rotating bearing frame and the connecting part.

Further, the spring component comprises a spring and a clamp spring for limiting the spring, and the spring and the clamp spring are sleeved on the rod piece.

Further, the spring shaft is integrally formed, and the connecting part is of an open loop structure, so that the spring shaft has elasticity and can generate torsion by friction with the fixed shaft, and therefore, damping sense is obtained.

Further, the arc concave structure is provided with a first connecting hole, the rod piece passes through the first connecting hole to be connected with the fixed bearing frame, the arc convex structure is provided with a second connecting hole, and the fixed shaft passes through the second connecting hole and the connecting part to be movably connected with the rotating bearing frame.

Further, the right-angle protrusions on the inner sides of the arc-shaped protrusion structures are arc-shaped right angles, and abrasion of the right-angle protrusions of the arc-shaped protrusion structures to the arc-shaped concave structures is reduced in the rotating process.

The utility model has the beneficial effects that:

1) The utility model adopts the mode that the arc concave structure and the arc convex structure are matched with each other, thereby realizing the overload function, being convenient for users with different facial forms to wear the glasses and avoiding the situation that the glasses cannot be worn due to too small glasses frame;

2) The utility model obtains torsion through the compression spring, and realizes automatic spring opening and closing.
