Problems solved by technology

[0002] The glasses hanger is mainly an auxiliary part of the glasses frame. For example, when walking in the sun, hang the hanger of the dark lens on the glasses, which can prevent the strong sunlight from irritating the eyes and play a protective role. At the same time, the glasses hang Frames are also widely used. Traditional eyeglass hangers such as clip-on sunglasses include many clips for detachably attachable short-sighted or long-sighted sunglasses so that the wearer does not need to carry or purchase another pair of short-sighted or long-sighted sunglasses. However, during the installation process, the metal medium on the clip may scratch the main lens of the glasses. Although the glasses hanger is located on the outside of the glasses, if the glasses hanger cannot coincide with the main lens well, it will block the sunlight. The effect is not guaranteed, and the vision of the eyes is affected at the same time, so that the part that the eyes see is dark and the part is white, which causes rapid fatigue of the eyes. In the frame beam telescopic device, the beam of the glasses hanger stretches and contracts through the return spring to make the two lenses move in the opposite direction, and the hanger opens, and then the hook on the glasses hanger is fastened to the main frame to fix it. This setting requires the wearer to simultaneously Only two hands can be used to wear or take off the glasses hanger. If the wearer wears the glasses hanger with both hands when driving a vehicle, it may cause unnecessary danger and trouble. Its appearance is not beautiful after being put on the lens, there are too many internal parts in the telescopic mechanism, and the setting is not reasonable enough
