Abstract

The utility model discloses a flat tip pencil sharpener which is invented to solve the troublesome sharpening and other problems of the prior art. The flat tip pencil sharpener comprises a cylindrical shell body and a pencil sharpener; a guide rail or a guide groove is axially arranged on the inner wall of the shell body; in the pencil sharpener, both sides of a sharpener holder are provided with a guide groove or a guide rail which is adapted to the guide rail or the guide groove of the shell body; the pencil sharpener cutter is arranged in the cylindrical shell body and can slide along the guide rail or the guide groove; a flat tip incision is arranged at a position of the bottom of the shell body which corresponds to a pencil lead outlet hole; and a reset spring is arranged between the bottom in the shell body and the bottom of the pencil sharpener cutter. After the structure is adopted, first the pencil holder of a pencil is sharpened into a conical shape, and a pencil lead extends out of the sharpener holder and then the sharpener holder is moved backwards, so that the pencil lead is inserted into the flat tip incision, the flat tip incision sharpens the pencil lead, and the purpose of sharpening a pencil tip into a flat shape (square shape or rectangular shape) is achieved.

Description

Flat nib pencil sharpener

Technical field

The utility model relates to a kind of pencil sharpener, particularly a kind of flat nib pencil sharpener.

Background technology

Pencil usually is made up of wooden penholder and the pen core that is provided with in the penholder, and is that its penholder cross section is generally circle or many ribs.

At present, generally its structure of the pencil sharpener of Shi Yonging is: as shown in Figure 4, a tool rest 7 that has the taper patchhole, be provided with bar shaped discharging opening 3 in taper patchhole one side, bar shaped discharging opening one side be fixed with blade 4, be sharpened in order to make pencil, the end of described taper patchhole is the circular port of slightly larger in diameter in the pen core diameter, but the formed awl point of the extended line of taper patchhole is positioned at tool rest, and the sharp tool rest that is provided with of correspondence awl is provided with blade, the sharp slightly length of length ratio awl of common blade; During use, pencil is inserted the taper patchhole, then in face of the blade Propelling pencil with sharpener in cap of blade, up to being whittled into conical getting final product to penholder and pen core; And at aspects such as design, drawing, drawing, card-coating, engineering constructions, the nib of this pencil will be whittled into flat (square or rectangle) in use usually, therefore existing pencil sharpener then can't be competent at, can only use craft such as pocket knife or blade to cut system, promptly inconvenient, waste pencil again, also occur unexpected easily.

The utility model content

For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of flat nib pencil sharpener easy to use simple in structure.

For achieving the above object, flat nib pencil sharpener of the present utility model comprises:

One barrel-type casing is axially arranged with guide rail or guide groove in inner walls;

One pencil sharpener comprises: have the tool rest of taper patchhole, be provided with the crumb mouth in taper patchhole one side, be fixed with the blade tangent with the taper patchhole on the tool rest of crumb mouth one side; Be provided with the pencil-lead suitable in taper patchhole bottom and stretch out the hole with pencil pen core diameter; Be provided with and housing guide rail or suitable guide groove or the guide rail of guide groove in described tool rest both sides, the described penholder cutter of cutting is located in the barrel-type casing and can slides along guide rail or guide groove; Wherein, the length of the length of blade and tool rest and taper patchhole is suitable, and the formed awl point of the extended line of taper patchhole is positioned at outside the tool rest.

Stretch out corresponding position, hole at described housing bottom and pencil-lead and be provided with the flat nib edge of a knife; The described flat nib edge of a knife can be an ordinary blade, also can be for a U-shaped blade so that be whittled into the nib of fixed thickness.

At described housing inner bottom part with cut between the penholder cutter bottom and be provided with back-moving spring.

Wherein, in described barrel-type casing, also be provided with a circular pencil sharpener side by side.

Wherein, be provided with baffle plate at described barrel-type casing opening sheet, the corresponding taper patchhole of cutting the penholder cutter is provided with the through hole suitable with it on the described baffle plate.

Adopt said structure, can be earlier the penholder of pencil partly be whittled into taper shape, and make pen core partly stretch out tool rest, mobile backward then tool rest, pen core is inserted to the flat nib edge of a knife, the flat nib edge of a knife is cut pen core, thereby reach the purpose that nib is whittled into flat (square or rectangle).

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1 to Figure 3, flat nib pencil sharpener of the present utility model comprises:

One barrel-type casing 1, housing can be square tube shape, also can be cylindrical shape; Be axially arranged with guide rail or guide groove 11 in inner walls;

One pencil sharpener comprises: have the tool rest 7 of taper patchhole, be provided with crumb mouth 3 in taper patchhole one side, be fixed with the blade 4 tangent with the taper patchhole on the tool rest of crumb mouth one side; Be provided with the pencil-lead suitable in taper patchhole bottom and stretch out hole 8 with pencil pen core diameter; Be provided with and housing guide rail or suitable guide groove or the guide rail 21 of guide groove in described tool rest both sides, the described penholder cutter of cutting is located in the barrel-type casing and can slides along guide rail or guide groove; Wherein, the length of the length of blade and tool rest and taper patchhole is suitable, and the formed awl point of the extended line of taper patchhole is positioned at outside the tool rest.

Stretch out corresponding position, hole at described housing bottom and pencil-lead and be provided with the flat nib edge of a knife 5; The described flat nib edge of a knife can be an ordinary blade, also can be for a U-shaped blade so that be whittled into the nib of fixed thickness.

At described housing inner bottom part with cut between the penholder cutter bottom and be provided with back-moving spring 6.

In summary, flat nib pencil sharpener of the present utility model is to cut the penholder part and to cut nib two parts separately, promptly, penholder with pencil partly is whittled into taper shape earlier, and making pen core partly stretch out tool rest, mobile backward then tool rest is inserted to the flat nib edge of a knife pen core, the flat nib edge of a knife is cut pen core, thereby reach the purpose that nib is whittled into flat (square or rectangle).
