Abstract: A multifunctional nail polishing head includes a grinding head and a grinding handle, a plurality of first helical grooves are defined on a circumferential wall of the grinding head at intervals, the grinding head is provided with a rack between every two adjacent ones of the plurality of first helical grooves, in a radial section of the grinding head, a plurality of sets of large tooth segment are formed along a circumferential direction of the grinding head, each set of the plurality of sets of large tooth segment consists of a plurality of racks, an arrangement density of the plurality of racks in one set of the plurality of sets of large tooth segment is from sparse to dense, or from dense to sparse, or alternates dense and sparse along the circumferential direction of the grinding head.

Abstract: A five-in-one polishing head includes a blade portion and a handle portion. The blade portion is shaped like a cone having a concave or planar top end. Angle teeth, thin teeth, medium-thin teeth, and thick teeth are sequentially distributed in a conical polishing head according to the tooth density. The angle teeth are located at the top of the conical polishing head in a circle. The thick teeth are located at the end of the blade portion. The center of the end of the blade portion is axially welded and fixed to one end of the handle portion. The conical polishing head is provided with regularly distributed straight lines or oblique lines on a surface from the angle teeth to the thick teeth. The shape of a right-handed groove on the surface is inverted trapezoidal, and the shape of a left-handed groove is triangular.
