Glasses frame with external expansion type elastic structure

The utility model relates to the technical field of glasses frames, in particular to a glasses frame with an external expansion type elastic structure, which comprises glasses frames and a cross beam, the inner sides of the left glasses frame and the right glasses frame are fixedly connected through the cross beam, lenses are fixedly connected in the lower parts of the glasses frames, and external expansion devices are mounted on the outer sides of the glasses frames. And a connecting device is mounted on the outer side of the external expansion device. When the glasses frame is worn, the two glasses legs can drive the pile heads to move towards the outer side through the supporting legs, the pile heads drive the second vertical plates to move, and the second vertical plates are matched with the first vertical plates to stretch the springs, so that the springs are elastically deformed; the glasses legs can be attached to the head of an operator through the elastic performance of the springs and the like, so t
