The utility model further provides that: all be equipped with the pilot hole that is used for assembling on the spectacle case on each inflection portion, the pilot hole is provided with a plurality of along connection piece length direction interval.

With the above further arrangement, the fitting hole can facilitate the folded portion to be connected to the case of the glasses case.

The utility model further comprises the following steps: the arc-shaped elastic pieces are arranged in a plurality at intervals along the length direction of the connecting piece.

By adopting the further arrangement, the use is more stable, and the service life of the device can be prolonged.
