The present application provides a kind of razor, including body, head structure, swing structure and dust cover, head structure includes head shell and multiple round head;The body includes casing, swing structure includes gear frame connected with head shell and head fixed frame connected with casing, head fixed frame is floatingly connected with gear frame, gear frame is equipped with first limiting part, head fixed frame is equipped with second limiting part;When under external force, first limiting part can be moved relative to second limiting part to realize that head shell is swung relative to casing, so that round head is shaved in the process of swing activity, when there is no external force, first limiting part and second limiting part are mutually close and fit in the rotation direction of motor shaft of drive motor, so that head shell does not occur relative to casing in the rotation direction of motor shaft in the starting moment of drive motor, guarantee the stability of round head, avoid the rotation of head shell in the rotation direction of motor shaft and the situation of running away.

This invention relates to the field of razor devices, and more particularly to a razor blade marking device, comprising a base plate, on which feeding devices are symmetrically arranged on both sides. Each feeding device includes a lead screw and a slide rod mounted on the base plate. The lead screw is driven to rotate by a feeding motor. The feeding device also includes a slide plate, through which the slide rod passes and is slidably connected. A threaded tube is fixed to the slide plate, through which the lead screw passes and is threadedly connected. A positioning rod for holding the blade is also provided on the slide plate. A support rod for cooperating with the blade is fixed above the base plate, passing through and slidably connected to the slide plate. A rotary motor is also fixed to the base plate, with a rotating seat fixed to the output end of the rotary motor. A laser marking head is fixed to the rotating seat. This device eliminates the need to individually place each blade, greatly improving the marking efficiency of the blades.

A razor blade. The razor blade includes a substrate having a first facet and a second facet that converge to define a cutting edge. A first textured surface is formed on the first facet and includes a first plurality of elements having a depth of between about 0.01 m and about 20 m. The first textured surface is spaced from the cutting edge by about 0.05 m to about 2 m.

A razor blade is provided comprising a substrate comprising a first portion and a second portion. The first portion may comprise first and second generally parallel outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet extending directly from the first outer surface of the first portion and an end facet extending directly from the first facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. The split line may pass through the tip and is generally parallel with and extends between the first and second outer surfaces of the first portion.

To provide a hair cut unit of a reciprocation type electric shaver.SOLUTION: A hair cut unit of a reciprocation type electric shaver includes an outer blade, an inner blade, a support, and a holder. The outer blade includes an outer blade arc-shaped wall and two opposite outer blade long walls, wherein the support supports the inner blade, and the holder includes two opposite holding walls. The outer blade long walls are provided with follow holes, at least the one support penetrates through the follow holes, and the outer blade long walls are movable along a support penetrating through the follow holes. When the cut unit receives non-uniform pressure from skin, the outer blade arc-shaped walls follow the moving outer blade long walls, can include the inner blade without being deformed, and accordingly can maintain high hair cut efficiency even at the time of actual use.SELECTED DRAWING: Figure 5
