The invention discloses a telescopic leg frame of linkage folding glasses, which is used for folding lenses and telescoping the leg frame of the telescopic glasses through the linkage of the transmission components. The transmission components and the guide components are matched by sliding friction. The transmission components comprise an elastic transmission part and a plurality of transmission parts. The shapes of fitting faces of the guide components are convex and concave. The transmission components pull and push the means of the movement of the ear hook component. The glasses have the advantages of convenient opening and closing and small size after being folded, and the leg frame has the advantages of simple structure, strong reliability and convenient process.
