Abstract
The invention discloses a pencil sharpener for a flat pencil point, which solves the problems of troublesome sharpening and the like in the prior art. The pencil sharpener comprises a cylindrical shell, a pencil sharpener, a flat pencil point knife edge and a return spring, wherein a guide rail or a guide slot is axially arranged on the inner wall of the shell; both sides of the knife seat are provided with a guide slot or a guide rail matched with the guide rail or the guide slot of the shell, and the penholder sharpener is arranged in the cylindrical shell and can slide along the guide rail or the guide slot; the flat pencil point knife edge is arranged on the bottom of the shell in the position corresponding to a pencil lead stretching hole; and the return spring is arranged between the inner bottom of the shell and the bottom of the penholder sharpener. The penholder part of a pencil can be firstly sharpened into conical by using the structure, the pencil lead part stretches out of the knife seat, the knife seat is moved backward to ensure that the pencil lead is inserted into the flat pencil point knife edge, the flat pencil point knife edge cuts the pencil lead, and the purpose of cutting the pencil point into flat (square or rectangular) is achieved.
Description
Technical field
The present invention relates to a kind of pencil sharpener, particularly a kind of Flat tip pencil sharpener.
Background technology
Pencil is comprised of wooden penholder and the pen core that is provided with in penholder usually, and its penholder cross section is generally circular or many ribs.
At present, its structure of pencil sharpener of generally using is: as shown in Figure 4, a tool rest 7 with 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 that slightly larger in diameter is in the circular port of pen core diameter, but the formed cone point of the extended line of taper patchhole is positioned at tool rest, and corresponding tool rest of boring the point setting is provided with blade, the sharp slightly length of the Length Ratio cone 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, until will be 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 can't be competent at, can only use the craft such as pocket knife or blade to cut system, namely inconvenient, waste again pencil, also easily occur unexpected.
Summary of the invention
For overcoming defects, the object of the present invention is to provide a kind of Flat tip pencil sharpener easy to use simple in structure.
For achieving the above object, Flat tip pencil sharpener of the present invention comprises:
One barrel-type casing is axially arranged with guide rail or guide groove in inner walls;
One pencil sharpener comprises: with 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 with the pencil-lead diameter and stretch out the hole bottom the taper patchhole; Be provided with in described tool rest both sides and housing guide rail or suitable guide groove or the guide rail of guide groove, the described penholder cutter of cutting is located in 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 cone point of the extended line of taper patchhole is positioned at outside tool rest.
Stretch out corresponding position, hole at described housing bottom and pencil-lead and be provided with the Flat tip edge of a knife; The described Flat tip 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 penholder cutter bottom and be provided with back-moving spring.
Wherein, also be provided with side by side a circular pencil sharpener in described barrel-type casing.
Wherein, be provided with baffle plate at the opening part of described barrel-type casing, on described baffle plate, the corresponding taper patchhole of cutting the penholder cutter is provided with the through hole suitable with it.
Adopt said structure, can be first the penholder of pencil partly be whittled into taper shape, and make pen core partly stretch out tool rest, then mobile tool rest backward, pen core is inserted to the Flat tip edge of a knife, the Flat tip edge of a knife is cut pen core, thereby reach the purpose that nib is whittled into flat (square or rectangle).
Description of drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the schematic diagram when cutting lead for retractable pencil embodiment illustrated in fig. 1.
Fig. 3 is that schematic diagram is looked on a left side embodiment illustrated in fig. 1
Fig. 4 is the structural representation of existing pencil sharpener.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1 to Figure 3, Flat tip pencil sharpener of the present invention 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: with 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 with the pencil-lead diameter and stretch out hole 8 bottom the taper patchhole; Be provided with in described tool rest both sides and housing guide rail or suitable guide groove or the guide rail 21 of guide groove, the described penholder cutter of cutting is located in 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 cone point of the extended line of taper patchhole is positioned at outside tool rest.
Stretch out corresponding position, hole at described housing bottom and pencil-lead and be provided with the Flat tip edge of a knife 5; The described Flat tip 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.
