[0013] Figure 3 is an enlarged detailed view of the specific details of the cutter head of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] As Figures 1 - 3 shown, a double-edged cutter head for a hair clipper, including a moving blade 100 and a static blade 200, both the moving blade 100 and the static blade 200 are of an annular structure, both the moving blade 100 and the static blade 200 have a center of a circle, and the centers of the moving blade 100 and the static blade 200 coincide. An outer ring toothed cutting edge a is arranged at the center of the outer rings of the moving blade 100 and the static blade 200, and an inner ring toothed cutting edge b is arranged at the center of the inner rings of the moving blade 100 and the static blade 200. In this embodiment, the main bodies of the moving blade 100 and the static blade 200 adopt an annular structure, and toothed cutting edges are arranged on both the inner and outer sides of the moving blade 100 and the static blade 200. The working principle of hair cutting is the same as that of a traditional hair clipper, that is, the moving blade 100 and the static blade 200 cooperate to achieve hair cutting. The advantage of setting inner and outer cutting edges is that during hair cutting, both the inner and outer cutter heads can fully contact the hair, which can effectively improve the hair cutting efficiency and neatness.

[0015] In the solution adopted in this embodiment, the static blade 200 and the moving blade 100 are arranged in an up-and-down distribution structure. The outer diameter of the static blade 200 is larger than that of the moving blade 100, and the inner diameter of the static blade 200 is smaller than that of the moving blade 100. This solution is more convenient for processing and assembly, and this solution is preferably adopted.

[0016] The static blade 200 and the moving blade 100 are arranged in an inner and outer covering structure. The outer diameter of the static blade 200 is larger than that of the moving blade 100, and the inner diameter of the static blade 200 is smaller than that of the moving blade 100. The inner ring toothed cutting edge b and the outer ring toothed cutting edge a of the static blade 200 are both formed into a cavity by bending. The outer ring toothed cutting edge a and the inner ring toothed cutting edge b of the moving blade 100 are both placed in the cavity formed by the static blade 200 to form a covering structure. This solution is more complex in processing and installation compared with the solution of the up-and-down distribution structure.

[0017] The static blade 200 has a threaded hole 210 for connecting the hair clipper, and the static blade 200 is fixedly assembled with the hair clipper by screwing a bolt 220 into the threaded hole 210; the moving blade 100 has a travel slot 110 through which the bolt 220 passes, and the moving blade 100 also has a connection hole 120 for connecting the drive assembly of the hair clipper. The installation structure of the static blade 200 and the moving blade 100, the travel slot 110 is an arc-shaped long slot that fits the annular blade body, mainly to ensure that when the moving cutter head rotates or swings left and right, it will not be blocked by the bolt 220. As for the hair clipper and the drive assembly, they are both conventional hair clipper structures, and no more details will be given here.

[0018] Arc-shaped bosses 230 are provided at the bottom ends of the outer ring toothed cutting edge a and the inner ring toothed cutting edge b of the static blade 200. The function of the arc-shaped bosses 230 is that they will not scratch the skin during hair cutting. That is, when the hair clipper is pushed on the scalp, the arc-shaped bosses 230 at the end of the cutter head first come into contact with the scalp, avoiding scratching the scalp with the toothed knife tips.

[0019] The present utility model provides an inner and outer double-edge cutter head for a hair clipper. By changing the traditional single-edge cutter head to a double-edge cutter head, when in use, the contact range between the cutter head and the hair is larger, and both the inner and outer cutter heads can cut hair, improving the hair cutting efficiency and the neatness of hair cutting, and it is convenient and fast to use, suitable for the elderly and people who need to cut short hair or shave their heads.

[0020] The above-mentioned direction words such as up, down, left, right, inner, and outer are all based on the attached Figure 1 drawing 1 or 2, and actually change accordingly according to the angle change and position of the product.

[0021] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, simple modifications and substitutions by ordinary technicians in the field are within the protection scope of the present utility model.
