An operation lever unit for a nail clipper having a clipper body with a pair of jaw portions to cut nail, the operation lever unit comprising:
- a lever member configured to move the jaw portions of the nail clipper from an opened position to a cutting position for cutting a nail inserted between the jaw portions;
- a thumb ring member rotatably mounted to a proximal end of the lever member, the thumb ring member including first and second ring members, said first and second ring members each having a generally circular, elliptical or oval ring shape with an inner opening through which a thumb of a user is to be introduced for clipping operation, the first and second ring members disposed in parallel relation to each other with a predetermined distance there-between which is greater than a width at a proximal tip portion of the clipper body, the thumb ring member further including a connection plate member of a predetermined width and length, said connection plate member formed unitarily with the first and second ring members into one piece, and thereby connecting and bridging between a lower portion of the first and second ring members, the connection plate member having a planar upper surface and including a bore formed vertically through the connection plate member;
- and
- a fastener coupled to the bore of the connection plate member and allowing the thumb ring member to freely rotate relative to the lever member to position the thumb ring member at various operating positions, said operating positions including a first operating position with the first and second ring members aligned in parallel relation with respect to the lever member, and a second operating position with the first and second ring members aligned in perpendicular orientation with respect to the lever member,
- wherein the nail clipper is configured to switch to a storing position with the lever member turned over to overlap the clipper body, thereby having each of the first and second ring members positioned laterally outside of the proximal tip portion of the clipper body with the first and second ring members in the first operating position, and allowing a compact storage configuration without having the first and second ring members interfered with the clipper body,
- wherein the connection plate member further include a counter bore at an upper side of the bore, and a head portion of the fastener is received in the counter bore so as to be generally flush with the planar upper surface of the connection plate member upon coupling, and thereby providing a wider contact surface in combination with the planar upper surface of the connection plate member.
