Abstract

The utility model discloses a pencil sharpener, in particular to a pencil sharpener which is particularly convenient to sharpen the carpenter pencil and widely used in various pens rotatablely sharpened, such as a pencil, a crayon and a makeup pencil, which comprises a sharpener body (1) and a blade (5); wherein, a tail end (11) of the sharpening edge takes a curving shape, and the curing shape is a straight line (11-1) or a curved line (11-2). The utility model has the reasonable structure design and the convenient production and processing, and can sharpen the pencil into a cylindrical thick pencil lead, which makes the utility model unnecessary to repeatedly sharpen the pencil when used; the utility model is particularly applied to carpenter pencils, eyebrow pencils, lip contour pencils, etc.

Description

Pencil sharpener

Technical field

The utility model relates to a kind of pencil sharpener, especially a kind of pencil sharpener of being convenient to cut carpenter's pencil especially, and it can be widely used in the various pens that need rotary cutting, as pencil, wax crayon, cosmetic pencil etc.

Background technology

Pencil sharpener is the instrument very widely that uses in people's daily life.In the prior art, the employed blade structure of pencil sharpener as shown in Figure 7, terminal 13 along continuous straight runs of its cutting edge are linearly, the pencil pen core 14 that comes out with this blade cut is cone, as shown in Figure 8, head is point, and very fast easily polishing needs cutting repeatedly, use very inconvenient, especially when needs use thick pen core, as the rule carpenter's pencil of usefulness of carpenter, cosmetic eyebrow pencil, lip liner etc.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of simple and reasonable for structure, can overcome the pencil sharpener of above-mentioned deficiency in the prior art.

The technical scheme in the invention for solving the above technical problem is: this pencil sharpener comprises cutter hub and blade, and its design feature is: the cutting edge of described blade is terminal to be bending.

Bending described in the utility model linearly.

Bending described in the utility model also can be camber line.

The utility model compared with prior art has the following advantages: reasonable in design, be convenient to production and processing, and can cut and be cylindrical thick pen core, make it not need in use to cut repeatedly, be particularly useful for carpenter's pencil, eyebrow pencil, lip liner etc.

The specific embodiment

Referring to Fig. 1, Fig. 2, cutter hub I of the present utility model is made up of annulus 1, movable axis 2, spring 3, screw 4, blade 5, gland 6, main body 7, connector 8, rotary body 9.Rotary body 9 is connected on the main body 7 by connector 8; Gland 6 is connected on the main body 7 by movable axis 2 and spring 3; Blade 5 is connected on the main body 7 by screw 4.

Referring to Fig. 3～Fig. 5, the movement locus of pen and blade during according to rotary cutting, the cutting edge of blade 5 of the present utility model terminal 11 is a bending, described bending is 11-1 or camber line 11-2 linearly.

Cutting edge described in the utility model terminal 11 refers to blade 5 position near nib on the cutting edge horizontal direction.

Referring to Fig. 1, Fig. 2, Fig. 6, during use, pencil 10 is inserted in the cone of main body 7 from the outer end of rotary body 9, and carry out rotary cutting, when being cut to certain position, the pencil pen core 12 that cutting is come out is cylinder.

Claims (3)

1, a kind of pencil sharpener comprises cutter hub and blade, it is characterized in that: the cutting edge end (11) of described blade (5) is a bending.

2, pencil sharpener according to claim 1 is characterized in that: described bending is (11-1) linearly.

3, pencil sharpener according to claim 1 is characterized in that: described bending also can be camber line (11-2).
