Abstract
Automatically stretchable folding spectacles, comprising: a first rim, with a first lens being provided within the first rim; a second rim, with a second lens being provided within the second rim; a first leg; and a second leg, wherein the first rim and the first leg are elastically connected via a first elastic member; the second rim and second leg are elastically connected via a second elastic member; a middle beam mechanism is provided between the first rim and second rim; and a locking mechanism is provided between the first leg and the second leg, which makes the spectacles capable of keeping a folded state after the spectacles are completely folded. The wearer needs only to press the locking mechanism with one hand, and the whole spectacles will stretch naturally and exhibit an available state under the action of the tension of the elastic members.
