Abstract

The utility model relates to a children's pencil sharpener for sharpening pencils, which comprises a sharpener frame (3), a blade (1) and a pencil sharpening hole (2). The improvement is that the blade can be movably positioned on the knife groove, and the pencil lead can not be cut by the blade through different positioning of the blade when the pencil is cut. The utility model has the characteristics of simple structure, convenient to use, difficult disconnected lead when cutting the pencil etc, be particularly suitable for preschool children or pupil to use, reinforcing children's hands-on ability.

Description

Pencil-sharpener for children

The utility model belongs to stationery, and particularly a kind of children bore graver.

Boring pen needs cutting to expose pen core before use.Cutting process can be used pencil-knife, also available brill graver, and a kind of method in back is well suited for children or pupil and uses, but that the brill graver of producing at present dynamics when the cutting pencil is grasped is bad, will cause the disconnected plumbous cutting effect that influences.

The way that solves all is usually when the cutting pencil, reduces into vigour of style in literary composition degree when cutting arrives pen core, and it is plumbous effectively to prevent from like this to break, but for preschool child or pupil, is difficult to implement this operation, because they also do not possess this ability.

The purpose of this utility model is to provide a kind of improved children to bore its disconnected plumbous phenomenon can effectively prevent to cut pencil time of graver device.

The purpose of this utility model is achieved in that former brill graver knife rest is strengthened, and makes blade removable location on the knife edge groove, and the difference location by blade during the cutting pencil can make blade cut less than pencil-lead, has prevented the pencil plumbous phenomenon of breaking.Also can shorten former brill graver blade lengths, make blade cut less than pencil-lead.

The utility model strengthens former brill graver knife rest or shortens blade lengths because of only needing, and structure is very simple, simultaneously because blade can running fix in the cutter groove, and the problem of cutting of applicable different thicknesses pencil.

Specify with by way of example below in conjunction with accompanying drawing

Fig. 1 shows that children bore the graver structure chart

Fig. 2 shows that children bore graver A-A profile

Among the figure, the 1-blade; 2-bores a hole; The 3-knife rest; 4-adjusts the hole; 5-knife edge groove; 6-blade location a chain for binding criminals silk; The 7-file; 8-file location a chain for binding criminals silk; 9-locatees scale.

Embodiment 1, and cutting 2HB pencil unloads file, adjusts blade (1) to locating the scale minimum of a value; Tighten blade location a chain for binding criminals silk, will bore graver and insert and Propelling pencil with sharpener in cap from boring a hole (2) front end, blade (1) is the machinable pencil, cuts the brill pen core of suitable length as required, and then cutwork is finished.

Embodiment 2, and cutting 2HB pencil is installed file, tighten file location a chain for binding criminals silk, adjust blade (1) to locating the scale minimum of a value, tighten blade location a chain for binding criminals silk, other work such as embodiment 1, and this moment, pencil-lead was pointed through behind the file pen core being worn into.
