[0040] Embodiment 2:

[0041] As shown in the drawings, Figure 6 The rolling member 4 is a lifting roller that can lift and tighten the skin, and the rolling body 40 is provided with at least two convex parts 41 distributed in the axial direction, and adjacent two convex parts 41 are connected by a concave part 42;

[0042] In this embodiment, as shown in the drawings, Figure 6As shown in (a) of FIG. 1, the convex part 41 has two, and the concave part 42 has one, which is located between the two adjacent convex parts 41. Each convex part 41 has a pressing section 411 in the middle to press the skin, and a stretching section 412 on both sides of the pressing section 411 to stretch the skin of the face. The stretching sections 412 on the opposite sides of the two adjacent convex parts 41 are connected by a smooth transition or a horizontal transition to form the concave part 42. The diameter of the stretching section 412 on both sides of the pressing section 411 decreases with the increase of the distance from the pressing section 411. When rolling in contact with the skin, the pressing section 411 pushes the skin inwardly, and the skin on both sides is pushed to the stretching section 412, so as to stretch the skin. The entire convex part 41 is a spindle-shaped rotary body structure with the outer diameter gradually decreasing from the middle to both sides. The convex part 41 with such a structure has a smooth surface, which can reduce the friction when contacting with the skin, and is more convenient to cooperate with the razor group to shave. On the other hand, the skin can be more smoothly stretched, so as to stretch the skin.

[0043] In actual situations, as shown in (b) of FIG. 1, the convex part 41 can also be provided with three, and the corresponding concave part 42 has two. The convex part 41 can only form the concave part 42 between the two adjacent convex parts 41. When the two convex parts 41 contact with the skin, the skin on both sides can be pushed and stretched toward the middle, so that the skin at the position of the concave part 42 can also be stretched. Figure 6

[0044] In another embodiment, the pressing section 411 and the stretching section 412 can have a clear boundary. At this time, the cross-sectional outer contour shape of the pressing section 411 can be an outward convex arc or a parallel-to-axis straight line, or other shapes, which mainly functions to roll on the surface of the skin to reduce the friction of the razor. The cross-sectional outer contour shape of the stretching section 412 can be one or more of an inclined straight line, an outward convex arc, and an inward concave arc, which mainly functions to stretch the skin. The concave part 42 can be directly formed by the stretching sections 412 on the opposite sides of the two adjacent convex parts 41, or can be formed by the stretching sections 412 on the opposite sides of the two adjacent convex parts 41 and a transition section between the two stretching sections 412, i.e. the transition section is located at the bottom of the concave part 42, and the cross-sectional outer contour shape thereof can be one or more of a horizontal straight line, an outward convex arc, an inward concave arc, and a wave shape.

[0045] The rolling member 4 is located between the two razor groups 3, as shown in (a) of FIG. 2. Figure 7 ​As shown, when all the cutter groups are located at the upper limit of floating (i.e. the guide part 310 is at the highest position), in the height direction, the highest point of the second cutter group 3b (i.e. the cutter group located at the inner side) is located higher than the highest point of the convex part 41 of the rolling member 4, and the highest point of the convex part 41 of the rolling member 4 is located higher than the highest point of the first cutter group 3a (i.e. the cutter group located at the outer side). The height arrangement enables the rolling member 4 to always be located between the first cutter group 3a and the second cutter group 3b in the height direction during the floating of the cutter groups, so that the linkage between the two cutter groups is smoother. The height of the second cutter group 3b can also be flush with the first cutter group 3a or flush with the rolling member 4, but at least the highest point of the rolling member 4 is located higher than the highest point of the first cutter group 3a, which can better ensure the linkage and connection functions of the rolling member 4.

[0046] Embodiment 3:

[0047] This embodiment is basically the same as the above-mentioned embodiment 2, and the difference is that in the above-mentioned embodiment 3, the convex parts 41 are integrally arranged on the rolling body 40, while in this embodiment, the convex parts 41 can be arranged in a separate rotating manner on the rolling body 40. For example, the convex part 41 is a shuttle-shaped cylindrical structure, and the rolling body 40 is a circular rod-shaped structure. The shuttle-shaped cylindrical convex part 41 is rotatably arranged on the circular rod-shaped rolling body 40. The convex part 41 arranged in a separate manner can also have the effect of lifting and pulling the skin.

[0048] Embodiment 4:

[0049] This embodiment is based on the above-mentioned embodiments 1-3, and as shown in Figure 1 and Figure 2 five cutter groups are arranged along the front-rear direction of the cutter head base 21, and they are sequentially arranged from front to rear as the first cutter group 3a, the second cutter group 3b, the third cutter group 3c, the fourth cutter group 3d and the fifth cutter group 3e. The linkage seats 44 are arranged on the static cutter frames of the first cutter group 3a and the second cutter group 3b, and the linkage seats 44 are also arranged on the static cutter frames of the third cutter group 3c and the fourth cutter group 3d.

[0050] The above-mentioned embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application.
