Abstract
The invention discloses a pencil sharpener with inner threads. After a steel piece is bent to form a conical hollow structure of a sharpener body with, a cylinder with inner threads is arranged on the end face of one end of a pencil inlet of the sharpener body in the axial direction and can be screwed in or out of the end of a wooden pencil through the inner threads. A blade is arranged at the inner end of the conical hollow structure of the sharpener body, the outer end of the conical hollow structure of the sharpener body covers the blade to enable the blade not to be exposed out of the end face of the outer end, and a shaving discharging gap is formed between the outer end and the blade and is communicated with the conical hollow structure. The blade and the shaving discharging gap extend from the pencil inlet to the small-head tail end of the sharpener body. Anti-slip convex stripes are arranged on the outer diameter face of the cylinder. The pencil point of the wooden pencil can be easily sharpened, the pencil sharpener is not separated from the wooden pencil, and the potential safety hazard that a user is stabbed by the sharp pencil point can be further eliminated. The pencil sharpener is especially suitable for a student.
Description
Technical field
The present invention 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.
Summary of the invention
The object of this invention is 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.
Technical scheme of the present invention 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 present invention 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.
Accompanying drawing explanation
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of concrete structure of the tapped pencil sharpener proposed according to the present invention.
