With the pencil sharpener with a curved cutting edge, students can conveniently sharpen proper column-shaped pencil tips which can extend writing time, and the pencil cores are not easy to break in sharpening. With compact structure and portability, the utility model is suitable for students, engineering drawing personnel, etc. to use.
Description
The utility model relates to a kind of stationery, is mainly used in to sharpen a pencil.
Pencil sharpener is the stationery that preprimary child and pupil use always.At present the pencil sharpener that uses mainly contains two kinds, and the one, blade is a flat, blade is linear pencil sharpener, though its safety simple to operate, the pencil of cutting out is not write several words with regard to chap, and yet frangibility of pen core in the working angles.The 2nd, the pencil sharpener that adopts differential milling garden to bore, though it is difficult for cutting disconnected pencil-lead, its structure is complicated, volume is big, cost is higher, also is not easy to carry.Because pencil manufacture craft and material problem are added the pure or children's misoperation of sword, pencil frangibility etc.
The purpose of this utility model is by adopting the pencil sharpener of new construction angle of throat, make the student be difficult for taking place pen core and cut disconnected phenomenon, and the pen core of cutting out can be write the long period, also is difficult for taking place the disconnected phenomenon of pencil sharper.
Above-mentioned purpose is achieved in that the utility model is made of tool rest and the angle of throat that is positioned on the tool rest with screw, mainly be that the angle of throat sheet is a curved-edge blade, the section of having on angle of throat is unilateral " V " shape curved slot, the degree of depth of its curved slot is between 0.5-1.0MM, and width is between 3.0-5.0MM.One or several curved-edge blades can be installed on the tool rest form series.
Use this song sword pencil sharpener to sharpen a pencil, the student can cut out the diameter of appropriateness easily at the garden of the different size of 0.4-1.3MM cylindricality pen core.Pen core is difficult for cutting disconnected, has also prolonged the time of writing, and its overall structure is tightly beaten, and is easy to carry, and is applicable to student and Graphing of Engineering personnel etc.
Accompanying drawing 1 is a front sectional structure schematic diagram.
Accompanying drawing 2 is a vertical view.
Accompanying drawing 3 is the bent sword pencil sharpener of a biplate vertical view.
Embodiment: with the bent sword pencil sharpener of monolithic is example.Tool rest 1 is with the once injection molded plastic casing of common plastics, is provided with pen-laying hole in the tool rest 1, and curved-edge blade 2 usefulness screws 3 are fixed on the upper surface of tool rest 1.Angle of throat sheet 2 employing carbon element steel bands are cold rolling, punching press heat treatment grinding forms.Will distance be arranged slightly between the pen-laying hole axis of angle of throat sheet 2 and tool rest 1 during installation, generally be advisable at 0.2-0.6MM, this distance is the minimum diameter of cutting pen core, forms garden post nib, and writing time can prolong.Tool rest 1 is provided with screw hole, so that mounting screw 3 when angle of throat sheet 2 is installed.This pencil sharpener can become series of products, and 1 or several angle of throat sheets are installed on a tool rest, and service time is longer.
