Description

Pensil sharpener

The utility model belongs to the school supply and stationery technical field, is mainly used in the planing pencil in the students'learning of school.

At present, the student is low, easy to use with the pencil-knife cost, but exists a fatal weakness, and the blade on the plane is a single-blade, and not how long with, edges dull can't be used, and has wasted steel, plastics, also is a loss economically.

The utility model has designed a hilted broadsword twolip pencil-knife at above-mentioned defective, but two planing pencil, and it is nearly 50% to have saved steel, plastics on original basis, nearly one times of service time.

Now be described in detail technology contents of the present utility model in conjunction with the accompanying drawings.

1 double-edged blade among the figure; 2 fixed screws; 3 alignment pins; 4 dig a bellmouth; 5 chip areas; 6 plastics dig body.

The utility model is improved on traditional pencil-knife basis and is formed, it is made up of planing tool, plane body, planing tool is a twolip, dig the conical bore that two space pens are arranged on one's body, conical bore two hole positioned opposite, its axis staggers mutually, planing tool place between two conical bores above, its two-edged is tangent with two conical bores respectively, and planing tool is fixed on the Luo silk on one's body the plane, digs and respectively is provided with a chip area along planing tool blade place on one's body.For making planing tool respectively establish a short slot at the planing tool two ends digging location on one's body, planing tool placed on one's body by plane and an alignment pin is respectively established in the position corresponding with planing tool two ends short slot, and by stretching out in the short slot.

During use, pencil put in any bellmouth rotate by hand, pencil-knife can be whittled into merit, if blade wearing and tearing rust can put in pencil in another bellmouth, by another blade pencil of planing.
