Abstract

The utility model discloses a pencil sharpener, which comprises a holder, a blade and a sharpening groove. The utility model is characterized in that the blade is fixed on the holder; the sharpening groove whose cross section is arc-shaped is arranged on the bottom of the holder; the sharpening groove is provided with an opening for the blade; the edge of the blade is arranged in the opening for the blade; the blade is arc-shaped; the holder is also provided with an object storing cavity, on the top of which a cover is provided. The utility model has the advantages that the pencil sharpener is safe, the pencil lead can not be broken when operating, the sharpening length of the wood part of the pencil can be controlled arbitrarily, and the pencil scraps can be prevented from dropping thus the clean environment can be kept.

Description

Pencil sharpener

The utility model relates to the technical field of the pencil-knife of the pencil of planing.

The pencil-knife exterior design of planing pencil use is different at present, but pencil all rotates with respect to blade in the planing process, easily does the folding lead for retractable pencil.It is all too short that planing length, the pencil guard timber planing length of pencil guard timber have been limited in the existing angle of inclination of pencil-knife blade on knife rest, is unfavorable for that the children that accept the initial stage culture and education form the good custom that holds a pen.

The utility model provides a kind of novel pencil-knife at the deficiency of existing pencil-knife, and this pencil-knife had both had the security of existing pencil-knife, can not break lead for retractable pencil when having operation again, the performance that the planing length of pencil guard timber can arbitrarily be controlled, and can collect shavings, keep clean environment.

Technical solution of the present utility model is such: a kind of pencil-knife comprises plane stock, planing tool, gouging, the cross section of gouging is curved, is opened in the bottom of plane stock, has edge in the gouging, planing tool is fixed on the plane stock, the blade of planing tool is located at the edge place, and blade is curved, mates with edge, be provided with in the plane stock and hold the thing chamber, hold top, thing chamber and be provided with the plane lid.

The utility model is offered gouging with new design in plane stock bottom, the operator is placed on edge place in the gouging with pencil, contacts with blade, move along groove, and the pencil of can planing, lead for retractable pencil can not fracture, and the planing length of pencil guard timber can optionally arbitrarily be controlled.The setting of holding thing chamber and plane lid can prevent that shavings is scattered, and keeps clean.In addition, because blade is located in the gouging, also has reliable security.

Below the utility model is described in further detail with embodiment.

Fig. 1 is a longitudinal profile schematic diagram of the present utility model.

Fig. 2 is a lower, transverse generalized section of the present utility model.

Fig. 3 is a side view of the present utility model.

As shown in Figure 1 and Figure 2, the utility model is by plane stock 1, and planing tool 2, gouging 3, plane cover 12 to be formed, and establishes edge 31 in the gouging 3.Planing tool covers 20 rear and front ends and contacts with planing tool 2, and central authorities arch upward, and with screw fit, planing tool 2 is fixed on the skew wall of plane stock 1.The blade 21 of planing tool 2 is located at edge 31 places, and with gouging 3 couplings, blade 21 is curved, also is provided with in plane stock 1 and holds thing chamber 11, holds thing chamber 11 and is provided with able to turn on or off plane lid 12.

As shown in Figure 3, the utility model is provided with mill road 13 on the sidewall of plane stock 1, and mill 13 surfaces, road are made by wear-resisting sand material, and profile and blade 21 couplings are convex, can pull down planing tool 2 when needing, and blade 21 can grind sharp thereon.
