Description

Rotary sharpener for moveable pencil

The utility model relates to a kind of propelling pencil pencil sharpener, belongs to the stationery class.

At present, the appearance of propelling pencil on the pencil market, the trend that replaces the conventional wooden pencil is arranged greatly, but because of the pen core of propelling pencil thin easily broken, pen core is thick write fuzzy plain, existing a kind of propelling pencil pencil sharpener comes out, can this pencil sharpener compare with the Wood pencil pencil sharpener that just size is little, structure is just the same, because the propelling pencil pen core rotates in penholder, be difficult for fining away, and inclination is arranged slightly, pen core folding section has a kind of disposable band point bull pencil to overcome above-mentioned deficiency in the recent period again, but need diligent change-fountain pen point, cause waste.

The utility model provides a kind of and is contained on the propelling pencil bar at the problems referred to above, pulls up during use, can be ground to the propelling pencil pencil sharpener of point to pen core.

Task of the present utility model is finished as follows: a pair of T type metal blade inboard is processed longitudinal stripe form the grinding cutting edge, pack into then the falling in the dovetail groove of column type pencil sharpener base, make two blades V-shaped, and by two projection plugs on the pencil sharpener base madial wall at two T type blade shoulders, the angle that limits two blades is the angle of tip of a pencil, the top center place of pencil sharpener cap leaves a small sircle hole that studs with metal edges, and column type pencil sharpener base hypomere is that internal diameter can be slidingly matched with pen core tube, external diameter is less than the pipe of penholder internal diameter.

The utility model produces ground effect because employing processes striped on sheet metal in the time of can making rotation pencil; Again because the angle of blade is the angle of pencil, the top center of pencil sharpener cap is stayed a small sircle hole that studs with metal edges simultaneously, rotates on the axis of pen core pen core is spacing, and pen core is frangibility not; Again because blade adopts the T type, make and leave a space of containing the pen end in the column type pencil sharpener base, and being slidingly matched of the pipe of column type pencil sharpener base hypomere and pen core tube, when pencil sharpener and propelling pencil are combined as a whole, also will as press with pen core in the penholder to outer propelling.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model overall structure figure

Fig. 2 is the pencil sharpener base structure chart

Fig. 3 is pencil sharpener cap figure

Fig. 4 is blade shapes figure

With reference to accompanying drawing 1,2,3,4, a pair of T type metal blade ［ 1 ］ inboard is processed longitudinal stripe form the grinding cutting edge, pack into then the falling in the dovetail groove ［ 3 ］ of column type pencil sharpener base ［ 2 ］, make two blades V-shaped, and by two projections ［ 4 ］ on pencil sharpener base ［ 2 ］ madial wall plugs at two T type blade ［ 1 ］ shoulders, the angle that limits two blades ［ 1 ］ is the angle of tip of a pencil, a small sircle hole ［ 7 ］ that studs with metal edges is stayed at the top center place of pencil sharpener cap ［ 6 ］, and column type pencil sharpener base ［ 2 ］ hypomere is that internal diameter can be slidingly matched with pen core tube ［ 8 ］, external diameter is less than the pipe ［ 5 ］ of penholder ［ 9 ］ internal diameter.During use, pencil sharpener is pulled up from penholder, pen core inserts the small sircle hole ［ 7 ］ of pencil sharpener cap, rotates the propelling pencil grinding and gets final product.
