The device is characterized in that the rotation rod, the lower scissor body, the upper scissor body, the press handle and the knife edge are assembledinto the nail clipper main body. The rubber pads are rectangular, one end of each support column is provided with the rectangular rubber pads, the length of the two rubber pads is same as the distance between the support columns and the knife edge, and the width of the two rubber pads is matched with the width of the lower scissor body and the width of the upper scissor body; the other ends of the support columns are vertically arranged in the lower scissor body and the upper scissor body respectively, the two support columns are arranged between the knife edge and the rotation rod, and thepositions of the two support columns correspond. When the device is in use, the rubber pads are compressed to clamp cut nails to prevent the nails from splashing, and when the press handle is loosened, the nails fall down along with opening of the rubber pads. The device solves the problem that the nails splash when an existing nail clipper is used for cutting the nails. The device is convenient to use, very low in cost and suitable for popularization.
