Abstract
The utility model relates to a single-edge and angle-changeable type pencil sharpener improved on the basis of the existing pencil sharpeners, comprising a cutting frame and a cutting blade fixed on the cutting frame. The front end part of the cutting blade tilts upward, and the included angle of the upward tilting part and the back part of the cutting blade is 172 DEG-178 DEG; the tail part of the cutting frame is closed. Pencils sharpened by the pencil sharpener have proper lead core nib, and writing force is easy to master. The sharpening degree of the utility model can be controlled, and the lead cores are not easy to break in sharpening.
Description
The utility model relates to a kind of sharpening device of pencil, a kind of single-blade angle pencil sharpener of more specifically saying so.
The blade of existing pencil sharpener only is a slice, and this pencil sharpener volume top rake degree is single, becomes tip-like according to the lead for retractable pencil of cutting out, and is uncontrollable according to the degree of cutting so that the lead for retractable pencil volume is cut loss is many, very easily disconnected point during use, and writing physical strength is difficult for grasp, and the stitching thickness difference of writing is big.The Chinese patent communique discloses a kind of " twolip pencil sharpener ", the patent No.: 93246481.5, be fixed with two blades on its knife rest, two blades are different with horizontal plane angle, its objective is the moulding that the control volume is cut degree and lead for retractable pencil, but when reality is used, serious disconnected plumbous phenomenon occurs in the joint of two blades, it is low that volume is whittled into power, can't normally use.
The purpose of this utility model provides a kind ofly can control that volume cuts that degree, the volume lead for retractable pencil thickness of cutting are moderate, volume is cut in the process the not single-blade angle pencil sharpener of easily broken lead.
The purpose of this utility model can realize in the following manner: a kind of improved pencil sharpener, include knife rest and the blade that is fixed on the knife rest, the leading section of blade upwarps, make between the rear portion of itself and blade and form an angle, angle is 172 °～178 °, the rear portion of blade is used for the roll cutting pencil bar, and front end is used for volume and cuts lead for retractable pencil.
The utility model compared with prior art has following advantage: this pencil sharpener is owing to be processed into the single-blade angle with a blade, making the nib of the pencil cut out of volume is not tip-like, but appropriateness by slightly gradually thin, thereby when writing not easily broken point, writing physical strength is very easily held, and lines are evener.Simultaneously cut not easily broken lead in the process at volume, and volume to cut in the process loss less.
Description of drawings:
Accompanying drawing 1 is a structural perspective of the present utility model.
Accompanying drawing 2 is structural front view of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings:
Shown in accompanying drawing 1,2: a kind of improved pencil sharpener, include knife rest 2 and the blade 1 that is fixed on the knife rest 2, the leading section of blade 1 upwarps, its angle that upwarps between the part and the rear portion of blade 1 is 172 °～178 °, thereby has formed similar twolip pencil sharpener, and the rear portion of blade 1 is used for the roll cutting pencil bar, the front portion of blade 1 is used for rolling up cuts lead for retractable pencil, the pencil thickness that volume is cut out is moderate, and by gradually thin mutually, dynamics is more easily grasped when writing.The afterbody sealing of knife rest 2, thus the degree that pencil is cut by volume can be controlled.
