Description

The diplopore pencil sharpener

The utility model belongs to pencil sharpening device technique field, relates to a kind of diplopore pencil sharpener.

Existing pencil-knife all is on pencil volume hole a blade to be arranged, during use, sharpen a pencil skin and pencil-lead carries out simultaneously, the pen core that the pencil of cutting out exposes is too short, too sharp, not anti-writing, when blade was sharp inadequately, pencil-lead was impaired easily: impaired when not too serious, the pencil-lead internal injury, one write broken; Impaired when serious, can't be whittled into, pen core constantly ruptures.

The purpose of this utility model is will provide a kind of a skin and pen core can be rolled up respectively cut, and makes pen core not be subject to contribute, and cut the pen core adjustable in length of system, whenever cut pen core one time, but writing time is long, the diplopore pencil sharpener that improves the efficient of writing.

The purpose of this utility model realizes with the following methods.This diplopore pencil sharpener comprises shell, pen-rolling hole, pencil sharpener sheet, and pen-rolling hole has two, pen-rolling hole for the hole of peeling, another pen-rolling hole for cutting the core hole, the pencil sharpener sheet corresponding with it, the Kong Shangwei that peels peel blade, cutting on the core hole to cutting the core blade.

Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail.

Fig. 1 the utility model front view

Fig. 2 is the A-A cutaway view of Fig. 1

Fig. 3 is the vertical view of Fig. 1.

Wherein: core hole, the 1-blade 2 of the peeling-tool rest 3 of peeling-adjustment seat 4-adjust bolt 5-cut core blade 6-cut core tool rest 7-pencil sharpener shell 8-pen-rolling hole 9-pencil sharpener sheet 10-hole 11 of peeling-cut

It is that two-stage is formed that the utility model is equivalent to by two pencil sharpeners, the shell that first order structure sharpens a pencil for hole (10) special use of peeling is promptly rolled up and is reamed the outer wooden skin of pencil-lead, and do not damage pencil-lead, cut in the process appearance, structural strength at volume and do not have influence at all pencil-lead.The outlet of taper hole in hole (10) of peeling is greater than pencil-lead, and when first order volume was cut, pen core was injury-free.There is the adjusting device of regulating pen core length the peel rear end in hole (10).This adjusting device is by adjusting (3) and constituting at the bolt of adjusting on the seat (3) (4), by regulating length adjustment arbitrarily between the 6-16 millimeter that bolt (4) can make pen core expose.Second level structure is to cut core hole (11), cuts the shape that core blade (5) is used for processing pencil-lead, the pencil-lead nose shape is met write, the needs of drawing etc.

The utility model is used for roll cutting pencil, make not easy fracture of pen core, saved pencil greatly, reduced environmental pollution, every volume is cut pencil one time, and the amount of writing of use increases, raise the efficiency more than ten times, because volume is peeled and pen core separates, and makes pencil sharpener not fragile, and improved more than 5 times the service life of pencil sharpener.
