Description
Technical field
The utility model relates to pencil sharpener technical field, especially a kind of tapped pencil sharpener.
Background technology
Existing pencil sharpener kind is a lot, except structure is usually complicated, also has the following disadvantages: one is with more painstaking during hand scroll point wood pencil written; Two is owing to depositing in addition after pencil sharpener use, usually meeting the embarrassment that can not find pencil sharpener at one's side for the moment; Three is sharp easy prick into human body of nib, there is potential safety hazard.
Utility model content
The purpose of this utility model be to provide a kind of easily can roll up sharp wood pencil nib, never leave each other with wood pencil and the pencil sharpener of the potential safety hazard of sharp nib prick into human body can be eliminated.
The technical solution of the utility model is: the tapped pencil sharpener comprising cutter hub, after described cutter hub is curled into conical hollow structure by one piece of steel disc, the end face of pen inlet one end of cutter hub is provided with tapped cylinder vertically, and described cylinder can pass through internal thread precession or back-out in one end of wood pencil.
The inner of the conical hollow structure of described cutter hub is set to blade, the end, outer end of the conical hollow structure of cutter hub covers above blade, make blade can not expose the end face of end, outer end, be provided with chip removal between end, described outer end and blade to stitch, described chip removal seam communicates with conical hollow structure.
Described blade and chip removal seam extend to the little tail end of cutter hub from pen inlet.
Anti-skidding burr is provided with outside the footpath of described cylinder.
Because the end face of pen inlet one end of cutter hub is provided with tapped cylinder vertically, only pencil sharpener written one end from wood pencil need be screwed in and turns clockwise, stylus head can be rolled up like a cork; Spool nib, be rotated counterclockwise, screw in a tail after taking off pencil sharpener, pencil sharpener can be fixed on a tail; Complete after writing, then taken off from a tail by pencil sharpener, screw in nib, the pencil sharpener being fixed on nib can cover sharp nib, thus eliminates the potential safety hazard of sharp nib prick into human body.
The utility model easily can roll up the nib of sharp wood pencil, never leaves each other and can eliminate the potential safety hazard of sharp nib prick into human body with wood pencil.Especially be applicable to student to use.
