发明名称 Concealed spring hinge for hairstyling devices
摘要 A hairstyling device includes two jaws hinged together about a transverse hinge axis around which a helical spring is helically wound. The spring is contained in an opaque casing attached to the first jaw and which has an end notch through which one second radially projecting end of the spring passes to bear against the second jaw. The casing is in one piece, with a rim at one end covering the outside edge of a first perforated lug to prevent rotation. Its other end has no rim but is associated with another first perforated lug which is oversized and has an outside edge substantially continuous with the outside lateral surface of the casing.
