As a preferred manner of the above, the multi-tooth portion and the mounting portion are integrally formed; the mounting portion is provided with a mounting hole for fixing.

Through the above technical solutions, the provided installation holes are convenient for installation, fixation, disassembly and replacement of the present invention.

As a preferred manner of the above, the alloy welding wire is welded between the bottoms of two adjacent teeth through gas protection.

Through the technical solution, the arrangement of the alloy welding wire helps to increase the strength of the upper teeth of the multi-tooth portion and prolong the service life of the utility model.

As a preferred embodiment of the above, the concave portion is arc-shaped.

Through the technical solution, the provision of the concave portion can reduce the material of the whole blade, and the concave portion is arc-shaped, which can increase the use safety of the present invention, and will not scratch the user when replacing the blade.

As a preferred form of the above, an arc chamfer is provided between the front and back surfaces of the mounting portion.

Through the above technical solutions, the setting of the arc chamfer can prevent the user from being scratched when the utility model is used and replaced.

As a preferred form of the above, the bottom surface of the guide block is in the shape of an arc, and several guide blocks are provided in the same direction as the axis of the mounting portion.

Through the above technical solution, the function of the guide block is that the bottom of the guide block can fit the head of the person to be barbered to perform a straight haircut when in use.

Compared with the prior art, the advantages of the present utility model are: 1. The installation holes provided are convenient for the installation, fixation, disassembly and replacement of the present utility model; 2. The setting of the alloy welding wire helps to increase the strength of the upper teeth of the multi-tooth portion, Increase the service life of the utility model; 3. The setting of the concave portion can reduce the material of the overall blade, and the concave portion is arc-shaped, which can increase the safety of the utility model, and will not scratch the user when replacing the blade; 4. The setting of the arc chamfer can prevent the user from being scratched when the utility model is used and replaced; 5. The function of the guide block is that the bottom of the guide block can fit the head of the barber to perform a straight haircut when in use.
