Abstract

The utility model discloses a double-face pencil sharpener, relating to a tool for planing wooden pencils. The double-face pencil sharpener is mainly composed of an outer shell, and upper and lower cutting blades, wherein, the two cutting blades are positioned on the upper and the lower sides of a jack, and are alternatively arranged on upper and lower cutting frames. Meantime, the two cutting blades are matched with each other. Thus, the utility model has reasonable structural design, a pencil nib and a pencil core are not easy to break in the process of planing, the planing is easy and complete, and the pencil nib is sharpen, etc.

Description

Two-sided pencil sharpener

The utility model relates to a kind of instrument of the pencil of planing, particularly a kind of two-sided pencil sharpener, and it mainly is applicable to the wooden pencil of planing.

Pencil sharpener structure of the prior art as shown in Figure 1 and Figure 2, it is mainly by shell 1 ' and blade 2 ' form, blade 2 ' by screw 3 ' be fixed on and shell 1 ' be connected on the knife rest of one; During use, can plane as long as put wooden pencil into jack 5 ' middle rotation; But the pencil sharpener of this structure remains in actual use in following shortcoming: 1, because this pencil sharpener has only single face a slice blade, it is stressed only in one side, so when pencil is planed the nib place slightly once the nib that firmly fractures easily, simultaneously, pen rocks in rotary course easily, nib is fractureed or is pushed up disconnected in the blade bottom surface; 2, single-edge blade is when blade loses sharp the time, and people will firmly rotate, and so just pencil can't be fined away or cut complete; Because this pencil-knife is subjected to the restriction of above structure, very easily cut disconnected nib or pen core, so people have to spend a large amount of time and cut at leisure with pocket knife, or cost dozens of yuan even unit up to a hundred remove to buy a mouthful penknife and solve problem, be not to lose time but do like this, be exactly economical inadequately, still have many problems.

The purpose of this utility model is to overcome existing deficiency in the prior art, and a kind of reasonable in design is provided, the two-sided pencil sharpener of the nib that can not fracture.

The purpose that the utility model proposes can be achieved through the following technical solutions: this pencil sharpener comprises shell and blade, and its design feature is that said blade is divided into cutter and bottom knife; The upper and lower surface of their seat jacks, and cutter and bottom knife mate mutually.

The purpose that the utility model proposes can also be come further perfect by the following technical programs: cutter and bottom knife are 0.3-0.5 centimetre in the gap at nib place.

Description of drawings is as follows:

Fig. 1 looks cutaway view for the master of pencil sharpener in the prior art.

Fig. 2 is the A-A cutaway view of pencil sharpener in the prior art.

Fig. 3 looks cutaway view for the utility model master.

Fig. 4 is the utility model B-B cutaway view.

Fig. 5 is a vertical view of the present utility model.

Following the utility model will be in conjunction with the accompanying drawings, and be described in further detail by embodiment.

Referring to Fig. 3, Fig. 4, Fig. 5, the utility model is made up of shell 1, cutter 6, bottom knife 9, upper tool post 7 and lower slide 8, cutter 6 and bottom knife 9 are fixed by screw 3 and upper and lower knife rest 7,8, the upper and lower faces of upper and lower blade 6,9 seat jacks 5, and alternately be installed on the upper and lower knife rest 7,8, upper and lower blade 6,9 mates mutually simultaneously, and promptly upper knife edge 6-1 mates mutually with following blade 9-1; For guaranteeing in use not break the tip of a pencil; Cutter 6 is 0.3-0.5 centimetre with bottom knife 9 in the gap of the H of nib place.In addition, the shape of shell 1 can be diversified.

During use, can plane as long as put in the jack 5 wooden pencil into rotation.

The utility model compared with prior art has following advantage: 1, reasonable in design, owing to adopt The upper and lower pencils of clamping of upper and lower two blades, make pen be difficult for rocking, and stress point is worked as usefulness in the rear end of pen Power when rotation order of strokes observed in calligraphy the knife edge prune wood chip and pen core, until cut complete or fine away; Simultaneously, two blades are digging Cut in the process, nib is the easiest cuts disconnected place when cutting, because upper bottom knife two sides is stressed, so nib can not fracture; 2, long service life: Double-face pencil sharpener is longer more than three times, even blade loses cutting edge of a knife or a sword than the life-span of single face pencil sharpener Profit, because of stress point in the rear end, so nib can not fracture yet; 3, because the nib place is designed with 0.3-0.5 Centimetre the gap, so nib can not fracture; 4, saved cost: because nib or pen core can not fracture, Greatly improve the service efficiency of pencil, saved cost.
