Abstract:
    The utility model provides a uneasy loosened rimless glasses screw cap. The rimless glasses screw cap has a hexagon surface for the application of force and the inner surrounded by the hexagon surface is provided with screw threads. A sleeve is formed by inward shrinking at one axial end of the rimless glasses screw cap and a soft circular rubber jacket is provided inside the sleeve. The screw rod cooperating with the screw cap has a screw cap cover at one axial end. The bottom of the screw cap cover is planar and in the middle stretches a rod body provided with screw threads. On the bottom the screw cap cover has cross furrows, whose crisscross has unequal lengths. Accordingly, when coupling the spectacle frame or the bridge with the lens by the screw rod, locking them with the rimless glasses screw cap can make lock firmly because the rubber jacket can absorpt shock. As a result, the coupled lens, the spectacle frame, the bridge, the screw rod, the screw cap and so on get protection and the service life will not shorten for usual disassembly.
