Detailed Description

Referring to fig. 1, 2, 3 and 4, an embodiment of the reciprocating razor outer blade of the present invention, the outer blade is integrally formed to include a skin-friendly wall 1 having a long shape and a width defined between two opposite lateral boundary lines, and support walls 2 formed by bending two lateral edges of the skin-friendly surface downward and parallel to each other. The integral n-shaped structure formed by the two supporting walls 2 and the skin-friendly wall has a certain guiding effect on the inner cutter, so that the assembly is facilitated, the integrally formed outer cutter has few processing steps, a smooth surface and no burrs, no sharp part is arranged at a bent part, the safety is better, the precision is very high, the matching performance with the inner cutter is better, and the consistency is good. The skin-friendly wall 1 is provided with a cutting blade which is bent back and forth and is in a snake shape and is formed by transversely and alternately arranging and extending a plurality of M-shaped cutting blade units A, the transversely adjacent M-shaped cutting blade units A are reversely connected, namely the transversely adjacent two M-shaped cutting blade units A respectively face two opposite transverse edges of the skin-friendly wall 31, each M-shaped cutting blade unit A comprises a left door part A1 and a right door part A1 with a door groove A4, reversing comb teeth A2 which are connected with the two door parts in the middle and protrude outwards from a transverse boundary line, the upper end and the lower end of an outer edge A11 of each door part A1 are respectively connected with a support wall 2 to form a support connection part 7 of the M-shaped cutting blade unit A on the support wall 2, a large through groove 3 is formed in an area between the two support connection parts 7 on the support wall 2 of the two door parts A1 of the M-shaped cutting blade units A1, the free ends of the reversing comb teeth A2 are bent downwards towards the large through groove 3 to form a Liuhai tips 6, the opposite sides of the large through grooves A3, and the cutting blade ends of the combing groove A and the inner wall are enlarged through the wide through grooves A4. In order to further improve and paste skin comfort level and security, the bang tip of this embodiment is outwards buckled and the most advanced circular arc transition of bang tip down the circular arc from horizontal boundary line, has avoided the outside circumstances that sticks up and influence skin feel and security of side tip. The bending radian of the section of the bang tip between the protruding transverse boundary line and the outer wall line of the support wall 2 is consistent with that of the support joint 7. This structure has ensured the close skin planarization of outer sword when convenient processing, and the security is high.

The cutting edge of the embodiment is arranged on the inner wall of the door groove A4 close to the outer side of the door part A1, the cutting edge A41 on the inner wall of the door groove A4 is parallel to the outer edge A11 of the door part, and the bottom wall of the door groove A4 is in a small-radius arc transition from the side where the self-reversal comb teeth A2 are located. The design of the door slot A4 enables the hair to enter conveniently, and the reverse comb teeth A2 connected with the door slot A can comb the hair softly and personally and ensure that the captured hair is cut at the cutting edge A41 smoothly and cannot be clamped.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
