Description

A kind of porous pencil sharpener

Technical field

The utility model relates to a kind of assistant product of writing or draw, and especially relates to a kind of porous pencil sharpener.

Background technology

Existing pencil sharpener, general all is the pencil sharpener of single hole single blade form, the pencil sharpener that diplopore double blade form is also arranged, as at open (bulletin) number CN2440670Y of disclosed Chinese patent on August 1 calendar year 2001, name is called a kind of diplopore pencil sharpener described in the utility application file of diplopore pencil sharpener, this kind pencil sharpener is provided with two taper pen-rolling holes and two blades, a taper pen-rolling hole is used for the wooden part of roll cutting pencil, another taper pen-rolling hole only is used for volume and cuts pen core, and purpose is can be implemented in a skin and the pen core of difference roll cutting pencil on the pencil sharpener.So such pencil sharpener can only be rolled up the pencil of cutting a kind of diameter, and can only be whittled into a kind of tapering to pencil, when cutting the pencil of different model or different taperings, must adopt a plurality of different pencil sharpeners to roll up and cut.

The utility model content

The purpose of this utility model is to overcome shortcoming of the prior art, provides can rolling up of a kind of three holes to cut two kinds of different-diameters and the combine volume graver that the pencil volume of same diameter is whittled into different taperings.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of porous pencil sharpener comprises tool-post structure, and the taper pen-rolling hole is set on the tool-post structure, and blade is fixed on the tool-post structure, and the inclined-plane of the blade of blade and taper pen-rolling hole is tangent, and described tool-post structure is provided with three taper pen-rolling holes.

In the technique scheme, the aperture of described middle taper pen-rolling hole is greater than left side taper pen-rolling hole and right side taper pen-rolling hole, and taper pen-rolling hole in left side is consistent with the pore size of right side taper pen-rolling hole.

In the technique scheme, the degree of depth of taper pen-rolling hole and right side taper pen-rolling hole in the middle of the degree of depth of described left side taper pen-rolling hole is longer than, middle taper pen-rolling hole is consistent with the degree of depth length of right side taper pen-rolling hole.

Compared with prior art, the beneficial effects of the utility model are:

1. the pencil sharpener of three kinds of different sizes of the utility model set is an one, can roll up the pencil of cutting two kinds of different-diameters, and the pencil volume of diameter of the same race can be cut out different taperings, and is easy to use.

2. the combine volume graver compact conformation that provides of the utility model is easy to carry about with one.

3. compared with prior art, the manufacturing cost of a combine volume graver is far smaller than three common single hole pencil sharpeners, when guaranteeing its function, has also saved manufacturing cost.

Description of drawings

Fig. 1 is the structural representation of combine volume graver.

Fig. 2 is that the I of Fig. 1 is to view.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

Referring to a kind of porous pencil sharpener shown in Figure 1, dotted portion is a taper pen-rolling hole 3 among Fig. 1, be arranged with 3, three blades 2 of three taper pen-rolling holes on the pencil sharpener tool-post structure 1 side by side and be fixed on the tool-post structure 1, and the blade of blade 2 and taper pen-rolling hole 3 inclined-planes is tangent.

Referring to Fig. 2, as preferably, the aperture of middle taper pen-rolling hole 32 is greater than left side taper pen-rolling hole 31 and right side taper pen-rolling hole 33, and left side taper pen-rolling hole 31 is consistent with the pore size of right side taper pen-rolling hole 33.When roll cutting pencil or paintbrush, middle taper pen-rolling hole 32 just can be used for volume and cut larger-diameter pencil or paintbrush, and the taper pen-rolling hole 31 and 33 of both sides is used to roll up pencil or the paintbrush of cutting common diameter, can realize rolling up pencil or the paintbrush of cutting two kinds of different-diameters.

Referring to taper pen-rolling hole 3 shown in Figure 1, taper pen-rolling hole 32 and right side taper pen-rolling hole 33 in the middle of the degree of depth of described left side taper pen-rolling hole 31 is longer than, middle taper pen-rolling hole 32 is consistent with the degree of depth length of right side taper pen-rolling hole 33.When volume is cut the pencil of common diameter or paintbrush, when needing volume to cut out elongated pen core, can cut by left side taper pen-rolling hole 31 volumes; When needs volumes is cut out thick pen core, can roll up by right side taper pen-rolling hole 33 and cut; When thinking that volume is cut larger-diameter pencil or paintbrush, can roll up and cut by middle taper pen-rolling hole 32.

Claims (3)

1. a porous pencil sharpener comprises tool-post structure (1), and taper pen-rolling hole (3) is set on the tool-post structure (1), blade (2) is fixed on the tool-post structure (1), the inclined-plane of the blade of blade (2) and taper pen-rolling hole (3) is tangent, it is characterized in that, tool-post structure (1) is provided with three taper pen-rolling holes (3).

2. a kind of porous pencil sharpener according to claim 1, it is characterized in that, the aperture of taper pen-rolling hole (32) is greater than left side taper pen-rolling hole (31) and right side taper pen-rolling hole (33) in the middle of described, and left side taper pen-rolling hole (31) is consistent with the pore size of right side taper pen-rolling hole (33).

3. a kind of porous pencil sharpener according to claim 1, it is characterized in that, taper pen-rolling hole (32) and right side taper pen-rolling hole (33) in the middle of the degree of depth of described left side taper pen-rolling hole (31) is longer than, middle taper pen-rolling hole (32) is consistent with the degree of depth length of right side taper pen-rolling hole (33).
