Detailed Description

The present invention will be further described with reference to the drawings and examples below in order to more clearly understand the objects, technical solutions and advantages of the present invention to those skilled in the art.

In the description of the present invention, it should be understood that the terms "upper," "lower," "left," "right," "inner," "outer," "transverse," "vertical," and the like indicate or are based on the orientation or positional relationship shown in the drawings, and are merely for convenience in describing the present invention, and do not indicate or imply that the apparatus or element to be referred to must have a specific orientation, and thus should not be construed as limiting the invention.

The invention will be described in detail below with reference to the attached drawings: as shown in figure 1, a rotary ceramic circular knife comprises a knife head body 1, wherein the body 1 is composed of a knife holder 2 and a knife head 3, the knife holder 2 is a circular connecting block, a rotary connecting hole 4 is arranged in the middle, a plurality of positioning holes 5 are further arranged around the rotary connecting hole 4, connecting pieces 6 which are distributed at equal intervals are arranged around the side of the knife holder 2, the knife head 7 is arranged on the connecting pieces 6, the knife head 7 is composed of a knife blade 8 and a connecting piece 9, the connecting piece 9 is fixed on the connecting pieces 6, two knife blades 8 are respectively arranged on two sides in front, the two knife blades 8 are integrally in an L-shaped structure, the front ends of the two knife blades are mutually closed to form a sharp knife tip 9, and a bottom plate 10 and the connecting piece 9 are arranged between the bottoms and the interiors of the two knife blades 8.

The rotary ceramic circular knife designed by the utility model has the advantages that the knife head consists of the blades and the connecting sheets, the two blades are of an L-shaped structure, the front ends of the two blades are mutually close to form a sharp knife tip, and the sharp knife tip can ensure that the whole shaving effect is better.

The rotary connecting hole 4 is internally provided with a circle of annular groove 12, an upper clamping interface and a lower clamping interface (not shown in the figure) are arranged in the groove 12, the clamping interfaces are clamped on a rotating shaft (not shown in the figure), the rotating shaft is fixed on a rotating drive (not shown in the figure), the upper surface and the lower surface of the tool apron are also provided with spring grooves 13, the spring grooves 13 are used for keeping the tool apron 2 at the middle position of the rotating shaft to move up and down, the spring grooves can penetrate through the whole tool apron, the length of a spring can be increased, and the spring can be elastically attenuated even after being used for a long time, so that the spring grooves are more ideal.

The annular groove can ensure that the ceramic circular knife after being mounted is firmly fixed and cannot shift to a great extent, and the arrangement of the spring groove can ensure that the knife holder keeps moving up and down at the middle position of the rotating shaft, so that the knife holder can better fit the extending beard for cutting, the comfort is ensured, the shaving effect is improved, and the use experience of a user is greatly improved.
