Abstract
Disclosed is a structure for assembling auxiliary spectacles with main spectacles by means of magnetic clips, in which the auxiliary spectacles are not easily separated from the main spectacles after the auxiliary spectacles are attached to the main spectacles. The structure has: at least a magnetic clip including a first magnetic portion and an assembling arm integrated with the first magnetic portion, the first magnetic portion containing a first magnet, the assembling arm having a first assembling hole formed through the assembling arm, the magnetic clip being assembled with the main spectacles by means of an assembling screw; and at least a magnetic attachment member having a first end, at which a second magnetic portion is disposed, and a second end integrated with the auxiliary spectacles, the second magnetic portion containing a second magnet, so that the auxiliary spectacles can be attached to the main spectacles by means of an attraction between the first magnet and the second magnet.
