Abstract

The utility model discloses a universal pencil sharpener, which comprises a cutter carrier (1), a cutter blade (2) fixed on the cutter carrier (1), and a conical pencil sharpening hole (4) which is arranged in the cutter carrier (1) along the edge (3) of the cutter blade; the pencil sharpening hole (4) is provided with a pencil sharpening slot (5) along the direction of the edge of the cutter blade; the cutter carrier (1) is provided with a limiting body (6) which is sleeved with the pencil sharpening hole (4); and the limiting body (6) is provided with a through hole (8). By adopting the structure, the universal pencil sharpener can not only cut pencils with different diameter, but also cut pencils with the same diameter into pencil leads with different diameters, and is convenient to carry.

Description

A kind of general use volume graver

Technical field

The utility model relates to a kind of sharpening device, relates in particular to a kind of general use volume graver.

Background technology

General pencil sharpener all has tool-post structure, be fixed on blade, the taper pen-rolling hole in tool-post structure on the tool-post structure, also have a volume groove that is provided with in pen-rolling hole upper edge knife-blade direction.During use, pencil is directly inserted taper pen-rolling hole scrolling just can cut.But such pencil sharpener can only cut the pencil pen core of identical thickness in working angles, and the pencil of different-diameter just is difficult to cutting.

In order to address the above problem, just must be equipped with the pencil sharpener of different size.So, the pencil sharpener that is designed to diplopore was also arranged afterwards, the pencil that can adapt to the different-diameter size cuts, but such technical scheme will increase the cost of single pencil sharpener, and volume increases, particularly at the eyebrow pencil user, often will carry such pencil sharpener, volume is in case increase is carried just very inconvenient.

The utility model content

The utility model provides a kind of and can be fit to the cutting of different-diameter pencil and can cut different thicknesses pen core and portable pencil sharpener at deficiency of the prior art.

In order to solve the problems of the technologies described above, a kind of general use volume graver of the present utility model, comprise tool-post structure, be fixed on blade on the tool-post structure, in tool-post structure along the taper pen-rolling hole of knife-blade setting, be provided with a volume groove in pen-rolling hole upper edge knife-blade direction, described tool-post structure is provided with the limit body with the pen-rolling hole socket, is provided with through hole in the described limit body.

In the technique scheme, the end that is shaped as of described limit body is provided with the cylinder of thrust along circumference, and described cylinder axial cross section is T-shaped.

In the technique scheme, described limit body is provided with the crest line of some projections, and described crest line is near being provided with an end of thrust, and extends axially along the limit body surface.

After adopting such structure,, can be fit to the pencil cutting of different-diameter because tool-post structure is provided with limit body, when needing the thicker pencil of cutting diameter, as long as unload limit body, when needing the thinner pencil of cutting diameter, only need limit body is socketed on the pen-rolling hole and get final product;

After adopting such structure, because tool-post structure is provided with limit body, can cut the pen core of different thicknesses to the pencil of same diameter, when unloading the structure of limit body,, cut thinner pen core easily because that the pen core of pencil enters the degree of depth of pen-rolling hole is deep, when socket upper limit body, because the internal diameter in hole diminishes, the degree of depth that pen core can enter also just shortens, and also just cuts thicker pen core easily.

As a kind of improvement of the present utility model, be provided with thrust at an end of limit body along circumference, make socket very easily of this limit body and dismounting; Limit body is provided with the crest line of some projections, and near at thrust one end, and the friction that can make limit body and pen-rolling hole produce squash type makes more firm being socketed on the pen-rolling hole of limit body.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

Extremely shown in Figure 4 by Fig. 1, a kind of general use volume graver, the taper pen-rolling hole 4 that comprises tool-post structure 1, is fixed on blade 2 on the tool-post structure, in tool-post structure, is provided with, be provided with a volume groove 5 in pen-rolling hole upper edge blade 2 blades 3 directions along the blade 3 of blade 2, described tool-post structure 1 is provided with the limit body 6 with the pen-rolling hole socket, is provided with through hole 8 in the limit body 6.The end that is shaped as of described limit body 6 is provided with the cylinder of thrust along circumference, and described cylinder axial cross section is T-shaped.Described limit body 6 is provided with the crest line 7 of some projections, and described crest line 7 is near ends that are provided with thrust, and extends axially along limit body 6 surfaces.

When needs cut the pencil of thick diameter, the user can unload limit body 6, and pencil is directly inserted taper pen-rolling hole 4, and the scrolling pencil just can cut the pencil of thick diameter; When needs cut the pencil of thin diameter, the user can connect limit body 6 covers, and pencil is directly inserted taper pen-rolling hole 4, and the scrolling pencil just can cut the carefully pencil of diameter.

In the time need cutting thinner pen core to the pencil of same diameter, the user can unload limit body 6, pencil is directly inserted taper pen-rolling hole 4,, cut thinner pen core during the scrolling pencil easily because that the pen core of pencil enters the degree of depth of pen-rolling hole is deep; In the time need cutting thicker pen core to the pencil of same diameter, the user can connect limit body 6 covers, pencil is directly inserted taper pen-rolling hole 4, because the internal diameter in hole diminishes, the degree of depth that pen core can enter also just shortens, and also just cuts thicker pen core during the scrolling pencil easily.

Though the utility model is described by embodiment; yet the utility model is not limited to embodiment as described herein; also be not limited to the pencil sharpener of cutting pencil or eyebrow pencil; as long as adopted by mode and realized cutting the pencil sharpener of function, all dropped among the protection domain of the present utility model with pen-rolling hole socket limit body.
