Description

Hair-cutting is changed with razor and hair-cutting and is used razor

(1) technical field

The present invention relates to hair-cutting that a kind of part cuts off hair with razor and supply with the hair-cutting replacing razor of hair-cutting with razor.

(2) background technology

To beautify hair is purpose and extensively adopt the hair-cutting razor.

For example, there is the Japan Patent spy to open the invention of the form of 2003-190675 communique record.

In this example, the cutter hub 32 of this razor 30 coats cutter edge 34 usefulness intermittently from cutter edge 34 outstanding half-circle projection 36, and cutter edge 34a that exposes and the cutter edge 34b that is coated alternately are provided with.

And the combing amount that is provided with between adjacent a pair of above-mentioned

projection

36,36 when cutting off hair with restriction is the groove 38 (with reference to Figure 16, Figure 17) of purpose.

(patent documentation 1) Japan Patent spy opens the 2003-190675 communique

But, in the above-mentioned background technology, when cutting off hair, the hair volume that exposes cutter edge 34a that is supplied to above-mentioned cutter hub 32 is stablized by projection 36, such advantage can obtain certainly, but identical with known this kind razor, the cutter edge 34a that exposes with respect to hair with right angle (cross) relatively (with reference to Figure 18, Figure 19).

Therefore, thereby do not deny can positively cutting off hair H by razor 30 is moved along the scalp of head T, but the problem below existing.

Because the cutter edge 34a that exposes is relative with the right angle with respect to hair H, so can not avoid always excessively cutting off the possibility of hair H.

Further specify this problem with reference to Figure 16～Figure 19, as shown in the figure, the cutter edge 34a of cutter hub 32 moves on right angle orientation with respect to hair H, can positively cut off hair H, the angle of inclination of this cutter edge 34a changes it from acute angle to the right angle more with respect to hair H, and to cut off function high more, but along with the raising of cutting off function, be easy to hair H is excessively cut off, the non-hair portion generation difference of cutting off the hair portion of portion and cutting off portion promptly may produce so-called " uneven in length phenomenon ".

On the other hand, for fear of the uneven in length phenomenon of hair H, even expressly excessively cut off the angle of inclination that hair changes cutter edge 34a for suppressing, but this operation is also not necessarily easy.

When oneself cutting off the hair H of head with razor 30, when especially cutting off the hair H at the head back side that is difficult to see, can only rely on intuition and so-called " tricks of the trade " carry out, so excessive the cutting off or the very few situation of the amount of cutting off of opposite hair that hair H may occur, the result is difficult to the phenomenon of avoiding uneven in length.

If avoid this uneven in length phenomenon, the cutter edge 34a of razor 30 must be connect angle with respect to bumping of hair H and carry out suitable adjustment.

But the operation of cutting off that the angle of inclination of the cutter edge 34a of razor 30 is set at necessarily, keeps implement unceasingly under the situation of this angle hair H is extremely difficult from saying in nature of handwork, and the result is difficult to adjustment and obtains balanced hair H.

(3) summary of the invention

Constitute existing problem for solving the above-mentioned background technology, the object of the present invention is to provide and a kind ofly can not cut off excessively that hair can not make the amount of cutting off of hair very few on the contrary yet, the hair-cutting that especially can not produce uneven in length phenomenon is with razor and supply with this hair-cutting and change hair-cutting razor with razor reaches and hair brush makes up with the hair-cutting of razor.

Other purposes of the present invention are to provide a kind of and change the preferable hair-cutting of finger etc., security that cutter when using with razor can not hurt human body with razor and hair-cutting replacing razor in hair-cutting with razor and hair-cutting.

Can simply understand razor is used in hair-cutting with razor and hair-cutting replacing other purposes with reference to following explanation and accompanying drawing.

Action effect

Technical scheme 1 is because have above-mentioned formation, so play following action effect.

Make this hair-cutting with the cutter hub side of razor towards hair, and make its along the general top side from the head of scalp to the neck side shifting.

At this moment, the point of a knife of cutter contacts on right angle orientation with respect to hair unlike background technology, but its point of a knife moves with wiping hair, so hair can not produce step, 1 hair cut off (with reference to Fig. 6) from cutting off beginning portion obliquely to cutting off tail portion.

In the present invention, move by making razor, thus the point of a knife of cutter along with the length direction of hair towards the below, when point of a knife being moved, cut off hair (with reference to Fig. 4, Fig. 5, Fig. 6) at leisure with wiping hair or cutting.

At this moment because the point of a knife of cutter is along hair contact and cut off, so the amount of cutting off of hair from the beginning side direction neck side little by little reduce.

This is because considering hair generally all is that the root of hair side is thick and tapered to the most advanced and sophisticated side of hair, thereby the self-sow situation of simulation hair can not produce so-called uneven in length (with reference to Fig. 4, Fig. 5, Fig. 6).

Technical scheme 2 is because have above-mentioned formation, so except that playing the action effect identical with technical scheme 1, also play following action effect.

When cutting off the hair of head rear side, generally be divided into two kinds of situations: a kind of be the right hand take the hair-cutting razor make the hair-cutting razor from the head the right side of rear side to neck side left to situation about moving; Another kind of opposite with first kind of situation be that left hand takes the razor of having hair cut to make the razor left side of rear side situation about moving to neck side right circular arc from the head.

And in these situations, the point of a knife of wishing cutter is towards its moving direction.

But, for satisfy this hope this razor must be divided into when producing the right hand with and left hand usefulness, but both are separately produced more numerous and diverse, and can cause the production cost increase, so the inventor is configured in different directions with the point of a knife of cutter as previously mentioned, can left and right sides dual-purpose thereby we can say.

Technical scheme 3 is because have above-mentioned formation, so play following action effect.

Except that the action effect that plays technical scheme 1 or technical scheme 2, because point of a knife is the boundary inclination with the hair-cutting razor with the datum line of mother metal, so can further improve the function of cutting off hair.

That is, cutting off of hair is that spherical scalp along human body carries out, but this moment cutter tool arc shape ground with the angular movement of certain limit.

Therefore, corresponding its angle when moving tilts point of a knife, thereby can obtain the angle of cutting off of near ideal, can further preferably cut off hair.

Technical scheme 4 is because have above-mentioned formation, so play following action effect.

Except that playing the action effect identical, because the non-arrangement arranged side by side of cutter, so especially when cutting off bob, for example male sex's hair, hair is stuck on the point of a knife of the cutter that exists with outstanding state easily, thereby helps to cut off bob with technical scheme 2.

Technical scheme 5 is because have above-mentioned formation, so play following action effect.

Except that playing the action effect identical, because the point of a knife of cutter is configured in equidirectional mutually and this cutter disposes side by side, so can expect to cut off the raising of function more with technical scheme 1.

Technical scheme 6 is because have above-mentioned formation, so play following action effect.

Except that

technical scheme

1,2,3,4 or 5 action effects that played, because be provided with the control assembly of the injury when suppressing to use the hair-cutting razor on the point of a knife next door, so can not hurt finger etc.

Technical scheme 7 is because have above-mentioned formation, so play following action effect.

Except that

technical scheme

1,2,3,4,5 or 6 action effects that played, because control assembly double as bristle, so can utilize cutter and bristle combing hair and cut off.

Technical scheme 8 is because have above-mentioned formation, so play following action effect.

Change with razor by having hair cut and to be installed on the hair-cutting razor body, thereby except that playing the action effect identical, use razor because razor can be changed the hair-cutting replacing when aging, so can always obtain cutting the hair-cutting razor of feeling good simply with technical scheme 1.

Technical scheme 9 is because have above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 2 and technical scheme 8.

Technical scheme 10 is because have above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 3 and technical scheme 8.

Technical scheme 11 is because have above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 4 and technical scheme 8.

Technical scheme 12 is because have above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 5 and technical scheme 8.

Technical scheme 13 is because have above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 6 and technical scheme 8.

Technical scheme 14 is because be above-mentioned formation, so play following action effect.

Can obtain the action effect identical with technical scheme 7 and technical scheme 8.

Technical scheme 15 is by integrally formed with razor and hair brush with hair-cutting of the present invention, thereby can obtain the action effect of the hair-cutting that also can expect in brush outbreak already.

Technical scheme 16 obtains the action effect identical with technical scheme 15 basically, but owing in the front and back towards the point of a knife of certain orientation bristle density is provided with difference, so the action effect of the operation that can obtain more successfully having hair cut.

Technical scheme 17 since the bristle density of point of a knife front side is set at littler than the bristle density of rear side, so the better action effect of completion status that can obtain having hair cut smoothly operation and brush are sent out.

Technical scheme 18 can obtain following action effect: when hair-cutting of the present invention being used razor and hair brush integrally formed, even cutting of point of a knife feels blunt, also can simply it be changed, always can continue to guarantee the necessary sense of cutting.

(5) specific embodiment

With reference to accompanying drawing, illustrate that the hair-cutting of the invention process form is changed the invention of using razor 20 with razor 10 and hair-cutting.

(embodiment 1)

Hair-cutting to example 1 is illustrated with razor 10.

In this example, the cutter 12 with point of a knife 12a is fixed on the hair-cutting razor with on the mother metal 14, and cutter 12 is arranged side by side, and each point of a knife 12a of 5 cutters 12 is an equidirectional, and point of a knife 12a is towards the left side (with reference to Fig. 1) in the drawings.

Moreover detailed will further specify, but example shown in Figure 1 be the back side at the hair of the scalp of head T from the right side preferred example when the neck side is cut off hair, can be described as the right hand and use.

On the other hand, the example symmetry, the point of a knife 12a that can be described as with Fig. 1 of example shown in Figure 2 uses towards the left hand of figure right side of face.

The basic comprising of these examples is: the cutter 12 that has point of a knife 12a is respectively holded up on hair-cutting razor usefulness mother metal 14, and this point of a knife 12a is configured on the right angle orientation with respect to the direction of holding up of cutter 12.

In this kind razor 10, generally all can handle 16 be set, but handle 16 only provides the facility in the use, so optional in the present invention at the end of razor of having hair cut with mother metal 14.

Quantity with cutter 12 of point of a knife 12a has only one to get final product in principle, but is generally more than 2, and example is preferably holded up about 5 as shown in Figure 1 and Figure 2.

With further reference to Fig. 3 the concrete formation of cutter 12 is described, the cutter that the plastics that the laminal cutter 12 of rectangle roughly takes the shape of the letter U in the cross section are made is with being built-in with point of a knife 12a in the shroud 12b, and this point of a knife 12a exposes from the open side of shroud 12b.

Cutter 12 as known to be metal, so when cutting off the hair of scalp, must consider dangerous strick precaution.

Therefore, in the present invention, the scalp that cutter 12 touches human body when preventing to use causes injury, thus except that cutting off the necessary point of a knife 12a of hair side, around it major part all use above-mentioned cutter with shroud 12b and hair-cutting razor with mother metal 14 coatings.

In addition, cutter 12 is generally lamellar as mentioned above, and undeniable its intensity is short of to some extent, thus use in the shroud 12b by it being built in cutter, thus hope increases the intensity of cutter 12.

Moreover, when cutter uses plastics with shroud 12b, when utilizing this material also to have can to avoid razor 10 to use to the advantage of the injury of scalp.

As shown in Figure 3, on the shroud 12b of cutter 12, on the right angle orientation of the relative extended line of the point of a knife 12a of cutter 12, be provided with 3 extended lines that surpass point of a knife 12a at regular intervals and outstanding slightly projection 12c.

By these projections 12c, except the intensity that can increase shroud 12b, owing at regular intervals projection 12c is set, thereby the hair H that imports 12 on adjacent cutter when cutting off can be cut apart by projection 12c.

Therefore, hair H is not concentrated in the part of point of a knife 12a, does not have the concentrated stress effect on point of a knife 12a, thereby except that cutting off sleekly the hair H, does not have the load effect on the point of a knife 12a.

The pin shape parts on the point of a knife 12a that holds up at cutter 12 next door are the control assemblies 18 of the finger tip of protection human body when razor 10 uses etc.

This control assembly 18 is not for hindering the hair H that imports point of a knife 12a when cutting off hair H, preferably depart from for example about 5mm from the center line of point of a knife 12a its position.

Action effect to the invention process form 1 describes (with reference to Fig. 4, Fig. 5, Fig. 6).

Making hair-cutting with cutter 12 sides of razor 10 towards hair H, and make its along the general top from the head of scalp T to the neck side shifting.

At this moment, the point of a knife 12a of cutter 12 relative hair H unlike background technology contacts on right angle orientation, but this point of a knife 12a along hair H and moving with wiping hair H.

This point is further described in detail, by razor 10 is moved, thereby the point of a knife 12a of cutter 12 towards the neck side of human body, and along hair H and wiping hair H ground and moving to the arrow Y of Fig. 4, Fig. 5 direction, cuts off hair H simultaneously along with the length direction of hair H at leisure.

At this moment, the point of a knife 12a of cutter 12 with respect to hair H unlike background technology on right angle orientation mobile cutter hub 32, but on the acute angle direction, move.

And, the point of a knife 12a that moves on the acute angle direction moves to the hair H that is positioned at the neck side at leisure from the hair H that is positioned at above-head, at this moment, the moving direction of point of a knife 12a is that relative hair H is close to parallel acute angle direction, so point of a knife 12a will never move on right angle orientation relative to hair H, thereby it is different with respect to the situation that hair moves on right angle orientation with cutter edge 34a in the background technology, hair H can be cut off with cutting, can obtain the hair H of taper state, thereby can not have the beautifying of hair (with reference to Fig. 6) of inharmonious sense.

Therefore,, thereby can not produce uneven in lengthly, can balancedly carry out the adjustment of hair because the portion of cutting off and the non-amount of cutting off of cutting off portion of hair H can not produce difference.

(embodiment 2)

Example 2 is illustrated.

With reference to Fig. 7 this form 2 is described.

This example is less with the difference of example 1 in essence invention, so only formations different on the principle is illustrated, identical formation is quoted the explanation of above-mentioned example 1.

Hair-cutting razor with handle 16 is with holding up 6 cutters 12 with point of a knife 12a on the mother metal 14 side by side.

The point of a knife 12a of the cutter 12 in the example 1 is all towards equidirectional, but in this example as shown in the figure, among the point of a knife 12a of 6 cutters 12, each adjacent point of a knife 12a towards being configured to different directions.

The configuration direction of these points of a knife 12a differs 180 degree mutually in illustrated embodiment, but is not limited to 180 degree.

Identical with example 1, be provided with the control assembly 18 of pin shape on the point of a knife 12a of cutter 12 next door.

Be readily appreciated that out from the explanation of example 1: example 2 is arranged on different directions mutually by the point of a knife 12a with cutter 12, thereby is had the advantage of energy left and right sides dual-purpose in use as can be known by the explanation of front.

(embodiment 3)

Example 3 is illustrated.

With reference to Fig. 8, Fig. 9 this example is described, in above-mentioned example 1, cutter 12 does not be arranged in parallel obliquely, but in this example, with the point of a knife 12a of cutter 12 towards being set at equidirectional, and with datum line L is that boundary is obliquely installed to the drawing upper right side, or is that boundary is obliquely installed (with reference to Fig. 8, Fig. 9) to the drawing upper left side with datum line L.

Therefore, this example is identical with example 1, confession right hand usefulness is arranged during use and supply left hand with two kinds.

When hair-cutting is used with razor 10, the angle of the relative hair H of point of a knife 12a often because of the combing position of user's hobby, hair H, to cut off the position different.

Moreover, infer: the angle difference of relative hair H because the hand of custom usefulness is different.

Therefore, the inventor considers the difference of above-mentioned service condition, attempts studying by experiment use angle.

Consequently learn: when for example custom is used the right hand, hair-cutting is moved from the right side to the neck direction obliquely with the hair H of razor 10 with right back head, when being benchmark with the combing hair H and the situation of cutting off, the angle of inclination of the point of a knife 12a of cutter 12 is the razor scopes of the datum line L of mother metal 14 to drawing upper left side inclination 10～80 degree of having hair cut relatively, is preferably about 60 degree (with reference to Fig. 8).

On the other hand, learn: when for example custom is used left hand, the angle of inclination of point of a knife 12a when being benchmark with the hair H of the left back head of combing and the situation of cutting off for and the razor of having hair cut symmetry noted earlier, relative with the datum line L of mother metal 14 to the tilt scopes of 100～170 degree of drawing upper right side, be preferably 120 degree (with reference to Fig. 9).

(embodiment 4)

Example 4 is illustrated.

With reference to Figure 10 this example is described, in above-mentioned example 1, the point of a knife 12a of cutter 12 only is arranged on a side, but is provided with point of a knife 12a in the both sides of cutter 12 in this example, thereby about need not distinguishing, is the example of considering in the use easily.

Other formations do not have different with example 1.

(embodiment 5)

Example 5 is illustrated.

With reference to Figure 11 this example is described, in above-mentioned example 1, the point of a knife 12a of cutter 12 is configured in equidirectional, and cutter 12 disposes side by side, but in this example, as shown in the figure, and 6 cutter 12n1,12n2,12n3,12n4, the non-configuration arranged side by side of 12n5,12n6.

That is, when overlooking, adjacent 6 cutter 12n point of a knife 12a separately towards different.

And, as shown in figure 11,6 cutter 12n1,12n2,12n3,12n4,12n5,12n6 from the left end of figure to right-hand member, the point of a knife 12a of the 1st cutter 12n1 (left end) is positioned at the top of drawing, the point of a knife 12a of the 2nd cutter 12n2 is positioned at the below of drawing, and cutter 12n2 is outstanding to the drawing top, the point of a knife 12a of the 3rd cutter 12n3 of next coming in order is identical with the point of a knife 12a of the 1st cutter 12n1, be positioned at the drawing top, the 4th cutter 12n4 and the 2nd cutter 12n2 same settings, below, repeat above-mentioned formation, the 5th cutter 12n5, the 6th cutter 12n6 (right-hand member) is concavo-convex to be non-formation side by side.

Adopt when so constituting, the 6th the cutter 12n6 point of a knife 12a next door separately that preferably is positioned at the 1st cutter 12n1 of left end respectively and is positioned at right-hand member on drawing is provided with control assemblies 18 such as foregoing safety pin, when purpose is that suppressing razor 10 uses to the injury of finger etc.

On the other hand, be positioned at cutter 12n2, the 12n3 between these both cutter 12n1,12n6, each point of a knife 12a of 12n4,12n5 and lay respectively at the inboard of the point of a knife 12a opposition side of each cutter 12n1, the 12n2 adjacent, 12n3,12n4,12n5,12n6 with difference.

Therefore, owing to be positioned at the inboard of the point of a knife 12a opposition side of the cutter 12n1 adjacent, 12n2,12n3,12n4,12n5,12n6 with point of a knife 12a, so finger waited the opposition side of each the point of a knife 12a that is subjected to these cutters 12n1,12n2,12n3,12n4,12n5,12n6 to disturb when razor 10 used, thereby except that the point of a knife 12a of cutter 12n1, the 12n6 of both sides, remaining might not need to be provided with above-mentioned control assembly 18.

(embodiment 6)

Example 6 is illustrated.

With reference to Figure 12 this example is described, in above-mentioned example 1, around cutter 12, do not hold up so-called bristle, but in this example, a plurality of control assemblies 18 of the above-mentioned bristle of double as is holded up the next door at point of a knife 12a.

The formation of cutter 12 shown in Figure 12 and the example symmetry shown in the above-mentioned example 5, but be not limited to this.

It is multiple that term in this specification " bristle " is also referred to as brush tooth, broach, bristle, comb tooth etc., shared with these words.

Be generally elongated pin shape, do not get final product but cross section short of corner angle except that circle can not hurt finger etc.

Moreover, when control assembly 18 double as bristles, can in combing hair H, carry out cutting off of hair H.

Below other example of the present invention is illustrated.

Following being noted that considers that above-mentioned hair-cutting wear out with use with the cutter 12 of razor 10, changes the example of using razor 20 at the hair-cutting razor with disassembled and assembled freely hair-cutting on the mother metal 14 for this reason.

Can know the detailed structure of hair-cutting replacing with reference to Figure 13～Figure 15 with razor 20, with respect to cutter 12 with not removable state be installed in the hair-cutting razor with the hair-cutting on the mother metal 14 with razor 10, this hair-cutting is changed with razor 20 and its difference and only is: be substituted in the razor of having hair cut and cutter 12, control assembly 18 be set at razor on mother metal 22 with mounting cutter 12 on the mother metal 14, so, omit its narration to quoting its explanation with the identical formation of razor 10 with above-mentioned hair-cutting.

In addition, the dismantled and assembled hair-cutting formation (with reference to Figure 13, Figure 14, Figure 15) of the razor of razor 10 with mother metal 22 is described in the lump.

Hair-cutting is holded up at razor with the cutter 12 of razor 10 and is used on the mother metal 22, has holded up control assembly 18 (with reference to Figure 13, Figure 14) on above-mentioned cutter 12 next doors.

In this example, cutter 12 is provided with 5, but its quantity is used identical can freely setting of situation of razor 10 as required with above-mentioned hair-cutting.

Hair-cutting is provided with the embedded hole 24 that is formed on the razor usefulness mother metal 22 with razor 10 detachables ground, so the form setting of cutter usefulness mother metal 22 corresponding embedded holes 24 is (with reference to Figure 13～Figure 15).

More particularly, a side of this mother metal 22 forms undulatory male and fomale(M﹠F) 22a, corrugated male and fomale(M﹠F) 22a corresponding the form undulatory male and fomale(M﹠F) (with reference to Figure 14) of razor with embedded hole 24 1 sides with mother metal 22 1 sides of mother metal 14 of having hair cut on the other hand.

Moreover the length direction both sides of mother metal 22 are formed with

block

22b, 22b.

On the other hand, the hair-cutting razor is formed with engaging stage portion 22e, the 22e (with reference to Figure 15) corresponding with above-mentioned

block

22b, 22b with the opening both sides of the embedded hole on the face side of mother metal 14 24.

Therefore, this hair-cutting with cutter 12 sides of razor 10 from the hair-cutting razor with the surface of mother metal 14 towards following, cutter is entrenched in the hair-cutting razor with mother metal 22 uses in the embedded hole 24 of mother metal 14.

And, the corrugated male and fomale(M﹠F) 22a of this mother metal 22 and the corrugated male and fomale(M﹠F) tabling of hair-cutting razor with the embedded hole 24 of mother metal 14, the block 22b, the 22b that are arranged in addition on this mother metal 22 are supported by engaging stage portion 22e, the 22e of hair-cutting razor with mother metal 14, thereby hair-cutting is changed with razor 20 and can not touched on mother metal 14 at the razor of having hair cut, can positively install, with razor 20 handgrip 22c (with reference to Figure 13) is set on this mother metal 22 for unloading the hair-cutting replacing.

Therefore, be entrenched in the hair-cutting razor with on the embedded hole 24 of mother metal 14 by this mother metal 22 of above-mentioned hair-cutting being changed with razor 20, thereby the cutter 12 that can obtain having point of a knife 12a is holded up at the hair-cutting razor with the razor 10 (with reference to Figure 13, Figure 14) of the hair-cutting on the mother metal 14.

Hair-cutting is installed to be changed with the hair-cutting of razor 20 identical with the action effect of razor 10 with above-mentioned hair-cutting with the action effect of razor.

When cutter 12 wears out, will have hair cut to change and unload with mother metal 14, and change with razor 20 by new hair-cutting is installed, thereby can simply obtain cutting off the preferable hair-cutting razor of function from the hair-cutting razor with razor 20.

Again other examples of the present invention are illustrated below.

That is, typically as shown in figure 20, be to make hair-cutting of the present invention with razor 10 integrally formed example in the bristle of hair brush, be understood that especially the density that is characterised in that bristle is different with rear side in the front side of point of a knife.

That is, in the relatively low side of bristle density, the resistance when actual brush is sent out etc. is little, and passing through of hair is good.On the other hand in bristle density upper side, it is big that the resistance that brush is sent out becomes relatively, but brush sends out and itself become fine and smooth and carefully carry out, and can realize good completion status.

Can select to improve relatively the bristle density of hair-cutting arbitrarily according to purpose with either side before and after the point of a knife of razor 10.But, for real experiences in the effect of having hair cut and brush is sent out, must be with minimum being set in more than 5% of bristle density relative different before and after the point of a knife.Preferable situation should be set at 10～30% with the bristle density contrast.

In the present invention, for having hair cut effectively and brush is sent out preferably bristle density with the point of a knife front side to be set at the rear side that compares low.That is, this is because wish that point of a knife can compare rough arrangement before hair-cutting, and the hair after the hair-cutting is applied careful brush outbreak industry.

Utilizability on the industry

When adopting foregoing invention, can be simply and realize rapidly suitable and safe hair-cutting operation, even There is not the people of special professional technique can positively realize the hair-cutting operation of expecting, simultaneously to professional skill is arranged yet The people of art also can need the delicate hair-cutting operation of numerous and diverse operation efficiently in the past, because be May bring the invention of the new wilderness demand of industry, so be construed as utilizability industrially Better.
