Description

  The present invention relates to a structure of a pencil sharpener capable of sharpening pencils corresponding to different types of pencils in consideration of convenience.

  Conventional pencil sharpeners are usually used as a single pencil sharpener and are stored in a part of a pencil holder or carried as they are. Pencils are often used using pencil sack, pencil holder, and pencil holder.

  For this reason, the user prepares a pencil sack, pencil holder, pencil holder, etc. separately from the pencil sharpener, and carries those multiple items as necessary, which can be said to be cumbersome and inconvenient. .

  In order to deal with the above problems, a pencil sharpener with a pencil sharpener described in Patent Document 1 and a pencil case with a pencil sharpener described in Patent Document 2, and other related products. Many ideas for combined products have been proposed.

  There are various types of pencils, for example, writing pencils of general dimensions / specifications used for writing in office work or learning, or drawing pencils used for painters. These pencils usually have different core diameters.

  A conventional pencil sharpener has a sharpened tooth structure having a size corresponding to the core diameter of a commonly used writing pencil. In addition, special drawing pencils have been centered by sharpening the pencil with a knife.

  Conventionally, as described above, many ideas for combining with related products have been proposed for pencil sharpeners, but no consideration is given to the difference in the core diameter of the pencil.

  The brush case described in Patent Document 2 has a structure in which at least two pencil sharpeners are assembled so that the pencil sharpening angle can be changed. In addition, the pencil sharpener described in Patent Document 3 is provided with two types of cutting blades before and after the pencil insertion hole to make the outer diameter of the core suitable for the user's preference.

  However, conventional pencil sharpeners including the pencil sharpeners described in the above-mentioned patent documents do not have a structure that takes into account the core sharpening that matches the core diameter of the pencil. As described above, the pencil sharpener that can handle both core diameters is larger in the core diameter of the pencil for drawing and the core diameter of the pencil for drawing that is generally commercially available. There wasn't.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pencil sharpener that solves the above-described conventional problems, can sharpen pencils corresponding to different types of pencils, and is excellent in convenience and portability.

  The pencil sharpener of the present invention, as described in claim 1, a pencil holder for storing and holding a pencil, a pencil sharpener unit, and a first pencil sharpening unit in which a shavings storage unit is integrated, A pencil sharpener unit corresponding to the core sharpening of a pencil having a core diameter different from that of the pencil that can be sharpened by the pencil sharpener of the first pencil sharpening unit, and a shavings storage part are integrated. A pencil sharpening unit, wherein the pencil holder, the first pencil sharpening unit, and the second pencil sharpening unit are formed in a substantially cylindrical shape, and the first pencil sharpening unit is attached to and detached from one end of the pencil holder The second pencil sharpening unit is detachably provided on the other end side.

  According to a second aspect of the present invention, in the pencil sharpener according to the first aspect, the first pencil sharpening unit and the second pencil sharpening unit are detachably provided to the pencil holder by the magnetic force of the magnet. It is characterized by being.

  According to a third aspect of the present invention, in the pencil sharpener according to the first aspect, the first pencil sharpening unit and the second pencil sharpening unit are detachably provided on the pencil holder by a screw structure. It is characterized by that.

  According to a fourth aspect of the present invention, in the pencil sharpener according to the first aspect, a hook member is provided on one side of the pencil holder portion, the first pencil sharpening unit, or the second pencil sharpening unit. It is characterized by that.

  According to a fifth aspect of the present invention, in the pencil sharpener according to the fourth aspect, an anti-slip member is fixed to a part of the hooking member.

  The invention according to claim 6 is the pencil sharpener according to any one of claims 1 to 4, characterized in that the pencil holder has a structure capable of extending and contracting in the axial direction.

  According to the pencil sharpener of the present invention, two pencil sharpening units capable of pencil sharpening (centering) corresponding to different core diameters are provided detachably with respect to the pencil holder portion, and the pencil sharpening unit has shavings. By providing the storage unit, convenience and portability are dramatically improved as compared with the conventional case where a plurality of pencil sharpeners, shavings storage units, and pencil holders are carried and carried individually.

  In addition, since the two pencil sharpening units are detachable, the user can remove and carry one of the pencil sharpening units as necessary, and the range of use is widened.

  Furthermore, the pencil sharpener is locked to the user's pocket or part of the document by providing a hooking member on one side of the pencil holder, the first pencil sharpening unit, or the second pencil sharpening unit. It can also be carried around.
