The utility model relates to a component of a glasses frame, in particular to an elastic glasses leg. The glasses leg is divided into a head section connected with a glasses frame and a tail section bent and hung on an ear; the head section of the glasses leg is in a sheet structure; a U-shaped through hole is punched in the middle of the bottom of the sheet head section to form a sheet body structure; only the edge of one end of the sheet body structure is in structural connection with the head section; the sheet body structure is bent inward to form an inward bent elastic sheet; the tail section is in a strip structure; and a thermoplastic pipe or rubber is mounted at the tail section in a sleeving manner. According to the glasses leg, the elastic sheet structure is punched at the tail part of the head section of the glasses leg, and has an elastic function by bending, so that elastic unfolding or folding of the glasses leg is achieved; the thermoplastic pipe or silica gel plastic or the rubber serves as an ear hanger part at the tail section of the glasses leg, so that assembly is facilitated, and a comfort level of wearing is raised; and the glasses leg is made of stainless steel, so that the quality and the grade of a product are improved and raised, and the glasses leg is suitable for people pursuing high-grade living.
