Definitions

  • the present invention relates, in general, to nail clippers and, more particularly, to a nail clipper, which is constructed so that a holding part pivots around one shaft, thus making it easy to hold the nail clipper, and which is provided with a stopper means, thus preventing cutting blades from being damaged when the nail clipper is not in use.
  • the present invention is directed to a scissor-type nail clipper, which is capable of eliminating noise when fingernails or toenails are cut, thus reducing the unpleasant feeling for surrounding people, and which is provided with a nail collecting tray for collecting removed fingernail or toenail fragments, so that additional cleaning operation is not required after the fingernails or toenails are cut.
  • a nail clipper is constructed so that cutting edges are provided on ends of upper and lower plates which are elastic and are connected to each other, a support shaft passes vertically through the front portions of the upper and lower plates, and a pressing plate serving as a lever is coupled to the support shaft.
  • the conventional nail clipper is operated as follows. That is, when the pressing plate is pressed, the cutting edges, which are provided on the ends of the upper and lower plates, bite each other, thus cutting fingernails or toenails.
  • the nail clipper is held in one hand, while the nails of the other hand are trimmed.
  • the nail clipper may obstruct a user's vision, according to the position of the nail clipper, so that it is difficult to neatly trim nails at one time, thus being inconvenient for the user.
  • the conventional nail clipper generates noise when nails are cut with a crack, thus giving an unpleasant feeling to surrounding people. Further, the cut nails may fly all around.
  • the nail clipper includes upper and lower plates each having on one end thereof a cutting edge, and a pressing piece which is coupled to the upper surface of the upper plate via a support shaft.
  • nippers are provided on ends of the upper and lower plates, and have edges which are aligned with each other in the same plane.
  • the upper plate has on the left side of one end thereof a left upper cutting edge, and has on the right side of one end thereof a right upper cutting edge.
  • a left lower cutting edge is provided on the left side of one end of the lower plate to correspond to the left upper cutting edge
  • a right lower cutting edge is provided on the right side of one end of the lower plate to correspond to the right upper cutting edge.
  • the cited reference 1 is characterized in that two pairs of cutting edges are provided on the left and right sides of the nail clipper, thus ensuring a user's vision so that the user can observe the nails which are being cut, preventing noise from being generated when nails are cut, and preventing cut nails from flying all around.
  • the cited reference 1 has a problem in that it is impossible to collect the cut nails.
  • This nail clipper has another problem in that force acts in a vertical direction, as in the conventional nail clipper, so that the wrist is strained, and thus a user may feel fatigue.
  • the nail clipper has a further problem in that it may slip from the hand during the use of the nail clipper, so that the nails or hands may be injured. Disclosure of Invention
