Abstract
The invention discloses a pencil sharpener which comprises a sharpener cover, a rotating shaft, a sharpener shell and a blade, wherein the sharpener cover and the sharpener shell are hinged and connected through the rotating shaft, the sharpener shell is a shell with a rectangular opening, the shell at the opening of the sharpener shell is shaped as a plurality of connected concave semi-circles, the blade is arranged in the sharpener shell, and one section of blade edge is exposed in each semi-circle concave at the opening of the sharpener shell. Most of the blade is hidden in the sharpener shell and a plurality of small sections of blade edges are exposed, thus a pencil can be conveniently sharpened without hurting hands, the pencil sharpener is very safe, is suitable for pupils to use, and is beneficial to the culturing of operation capability of the pupils.
Description
Technical field
The present invention relates to a kind of daily living article, particularly a kind of pencil-knife.
Background technology
The blade of the pencil-knife that exists is exposed to outside the handle of a knife fully at present, if it is just abnormally dangerous that child uses, accidentally just may cut and set about, present most of pupil's pencil all is that the head of a family cuts, and is unfavorable for very much cultivating pupil's self-manipulative ability.
Summary of the invention
The problem to be solved in the present invention is: a kind of pencil-knife that is difficult for hindering hand is provided.
For addressing the above problem, the present invention includes cutter lid, rotating shaft, cutter shell and blade, cutter lid and cutter shell are articulated and connected by rotating shaft, the cutter shell is a housing with an oblong openings, the hull shape at cutter shell opener place is a plurality of be connected and semicircles of caving inward, blade is installed in the cutter shell, all exposes one section blade in each semi-cylindrical canyon of the opening part of cutter shell.
For easy to use, one side that described cutter covers be shaped as a plurality of be connected and semicircles that outwards protrude, cutter covers semi-cylindrical hill and first circular depressed of cutter shell is corresponding one by one, cutter covers semi-cylindrical hill and can be inserted in first circular depressed of cutter shell.
In order to improve security, described blade tilts to be installed in the cutter shell, all expose the blade that a segment length does not wait in each semi-cylindrical canyon of the opening part of cutter shell, one side that cutter covers be shaped as a plurality of be connected and semicircles of caving inward, cutter covers semi-cylindrical canyon and first circular depressed of cutter shell is corresponding one by one, when cutter lid and cutter shell closure, semi-cylindrical canyon on semi-cylindrical canyon that cutter covers and the cutter shell is formed a plurality of circular holes, expose the blade that a segment length does not wait in each circular hole, be provided with locker between cutter lid and the cutter shell.
Beneficial effect of the present invention: blade major part of the present invention is hidden in the cutter shell, only exposes the blade of a plurality of segments, promptly can sharpen a pencil very easily, can not hurt hand again.Fool proof, be suitable for the pupil and use the self-manipulative ability that helps cultivating the pupil.

The specific embodiment
Specific embodiment one
A kind of specific embodiment as depicted in figs. 1 and 2, it comprises cutter lid 1, rotating shaft 2, cutter shell 3 and blade 4, cutter lid 1 and cutter shell 3 are articulated and connected by rotating shaft 2, cutter shell 3 is the housings with an oblong openings, the hull shape of cutter shell 3 opening parts is a plurality of be connected and semicircles of caving inward, blade 4 is installed in the cutter shell 3, the blade that all exposes one section equal length in each semi-cylindrical canyon of the opening part of cutter shell 3, one side on the cutter lid 1 be shaped as a plurality of be connected and semicircles that outwards protrude, cutter lid 1 first circular protrusions and cutter shell 3 first circular depressed are corresponding one by one, and cutter lid 1 first circular protrusions can be inserted in cutter shell 3 first circular depressed.
Using method: when pencil-knife is in state shown in Figure 1, open cutter lid 1, the blade of blade 4 exposes, and can select for use the blade in any one semi-cylindrical canyon to sharpen a pencil.Because the position protection outside the outstanding blade of semi-cylindrical canyon is arranged, and finger is difficult for the contact blade, therefore is difficult for hindering hand, after having cut, closed knife lid 1 gets final product.
Specific embodiment two
A kind of specific embodiment as shown in Figure 3 and Figure 4, it comprises cutter lid 1, rotating shaft 2, cutter shell 3, blade 4, stator 5 and fixed axis 6, cutter lid 1 and cutter shell 3 are articulated and connected by rotating shaft 2, cutter shell 3 is the housings with an oblong openings, the hull shape of cutter shell 3 opening parts is a plurality of be connected and semicircles of caving inward, blade 4 tilts to be installed in the cutter shell 3, all expose the blade that a segment length does not wait in each semi-cylindrical canyon of the opening part of cutter shell 3, one side on the cutter lid 1 be shaped as a plurality of be connected and semicircles of caving inward, cutter lid 1 first circular depressed and cutter shell 3 first circular depressed are corresponding one by one, when cutter lid 1 and cutter shell 3 closures, semi-cylindrical canyon on the cutter lid 1 and the semi-cylindrical canyon on the cutter shell 3 are formed a plurality of circular holes, expose the blade that a segment length does not wait in each circular hole.Stator 5 is fixed on the cutter lid 1, and fixed axis 6 is fixed on the cutter shell 3, and stator 5 is provided with diameter than the big hole of fixed axis 6 diameters, and when cutter lid 1 and cutter shell 3 closures, stator 5 and fixed axis 6 are interlocked.
Using method: in the time will cutting a new pencil, untie stator 5 and fixed axis 6, cutter lid 1 is turned to state as shown in Figure 4, selects one section suitable blade to sharpen a pencil, just lead for retractable pencil need be cut when pencil and grow when a bit, should cover the cutter lid, fasten stator 5 and fixed axis 6, selected one section suitable blade to sharpen a pencil, at this moment, blade is in the circular hole, more is difficult for hurting hand.
