Description

A kind of adjustable pencil sharpener

The utility model is about a kind of pencil sharpener, and particularly adjustable pencil sharpener belongs to cultural goods.

The pencil sharpener kind of Xiao Shouing is a lot of in the market, the blade of being adorned on it is fixed, be subjected to the restriction of pencil model thickness so in use, just not too suitable to thicker pencil such as B6 type etc., sometimes the pencil of cutting is crossed point and should not be write, this type of pencil sharpener easily makes pen core fracture in addition, and current still do not have a pencil sharpener preferably.

The purpose of this utility model is the weak point that solves above-mentioned pencil sharpener, and the cutting that provides a kind of energy to be suitable for various model pencils is cut system lead for retractable pencil length and can oneself be controlled, and adjustable pencil sharpener easy to use.

The utility model is achieved in that has a taper hole shape that matches with pencil to cut a groove on body, with the cracking of taper hole on movably blade is housed, there is the mill stereotype body one side.

Below with reference to drawings and Examples the utility model is described in further details.

Fig. 1 is the utility model first example structure schematic diagram;

Fig. 2 is the utility model mill stereotype partial structurtes schematic diagram;

Fig. 3 is the utility model blade folder spring schematic diagram;

Fig. 4 is a blade structure schematic diagram among the utility model second embodiment.

1. cut 9. springs of a groove 2. insert grooves 3. blades 4. indents 5. handle of a knifes 6. blades folder spring 7. hole clippings, 8. mill stereotypes, 10. grooves, 11. screws among the figure

The utility model comprise have on the body that a taper hole shape and pencil match cut a groove 1, have on the taper hole and crack, blade 3 be installed in crack with insert groove 2 on, blade 3 can be indulged and ask mobilely, in a side of body mill stereotype 8 is arranged

The utility model can be that handle of a knife 5 is arranged on the blade 8, and top is pressed on the indent 4 of blade 3 by blade folder spring 6, and the two ends of blade folder spring 6 are stuck in the hole clipping 7 on the body.

The utility model can also be that its mill stereotype 8 is made up of two plates of mill line the surface, and its a slice links to each other with axle spring 9, can limit the movable angle of two plates.

But the utility model can also be a screw 11 of establishing groove 10 and the fastening blade of turn that is mounted in it on the blade 3, and blade is vertically moved along groove 10.

During use, the pencil of the applicable various models of the utility model, the diameter of visual pencil-lead of time spent, promote the handle of a knife on the blade, sliding blade is along groove and cut a groove sliding blade to the position that is fit to, inserting pencil afterwards rotates, cut the wooden skin of starting writing, more bigger because of cutting a groove taper hole top end diameter than common pencil sharpener, therefore lead for retractable pencil can complete back-out from topped hole, withdraw from behind the pencil more as required on the mill stereotype that to clip two plates with hand angled, rotate pen core and be ground to suitable angle, also removable blade is repaired the nib of non-standard pencil.

The utility model is simple in structure, and is rationally easy to use, is a kind of more satisfactory adjustable pencil sharpener.
