Abstract
The utility model relates to a pencil sharpener with a separable knife blade. The utility model is characterized in that a pencil cutting wood layer is separated from a pencil-lead cutting knife blade, a definite cutting angle is kept between the pencil-lead cutting knife blade and a pencil-lead, and the pencil-lead cutting knife blade is fixed on deformable elastic plastics. When a pencil is cut, the pencil-lead cutting knife blade can do light displacement outwards, so the cutting pressure of a pencil core can be reduced. The pencil sharpener can complete the cutting of the pencil one time and can balance the cutting force. In addition, the utility model has the characteristics of no breaking cores, smooth and orderly pencil core, beautiful and durable pencil, fluent writing, environmental protection, economy, etc.
Description
Technical field
The utility model relates to a kind of pencil-knife, and particularly a kind of blade separate type pencil-knife is the improvement to traditional pencil-knife.
Background technology
Existing pencil-knife has only a blade, skin and pen core to pencil cut simultaneously, the pencil that this single blade cutting way cuts can only be a cone shape, the cutting force that pencil is suffered and the size and Orientation of breaking force also are identical, easily disconnected core in the process of cutting, the while is outer wooden different with pen core hardness because of pencil, and the cutting dynamics that pen core is subjected to is inhomogeneous, easier disconnected core causes very big waste.Existing pencil-knife, the outer layer of wood of pencil and pen core are on the same conical surface during cutting, pen core is peeled off not exclusively with a layer of wood, and pen core excessively cut, the pen core cutting is not neat, fractures easily during use, the easy chap of person's handwriting, write not smoothly, need frequently cutting, shorten the service life of pencil.
Summary of the invention
The purpose of this utility model provides a kind of blade separate type pencil-knife, adopts double blade to separate the different piece of cutting pencil, changes the cutting way of existing pencil-knife, and the balanced cutting dynamics has good protective effect to pencil-lead.
The utility model comprises housing, bellmouth, cutting pedestal and cutting tip, is provided with elastic plastic member on the cutting pedestal, and elastic plastic member is the bow type, and an end is fixed on the base, and the other end is connected on the cutting pedestal; Bellmouth center line one side at housing successively is equipped with two blades, and a blade is installed on the pedestal, and another blade is fixed on the elastic plastic member, is provided with displacement position-limiting between two blades.
The utility model is by using different blades to cut to pencil layer of wood and pencil-lead, realizing once finishing cutting.During operation, pencil imports and rotation at bellmouth, and the outer cutting tip of pencil neatly cuts the hard layer of wood of pencil earlier, after separating pencil-lead, pencil-lead is derived through the pen core guide hole, is cut by the pencil-lead cutting tip, and whole different pen core requires to determine dissimilar apertures.Pen core cutting tip and pencil-lead have certain cutting angle, pencil-lead is realized conical cutting, the pen core cutting tip is fixed on the bow type elastic plastic member, bow type elastic plastic member one end is fixed on the base, one end is connected on the outer cutting of the pencil pedestal, when being subjected to pushing, and the distortion of bow type elastic plastic member, drive the outwards slight displacement of blade of cutting pencil-lead, reduce the cutting pressure of pen core.The utility model can be set the aperture and the blade position of different pen core guide holes according to different pencil types, to satisfy the cutting requirement of different pencil types.
The utility model is compared the advantage that has with traditional pencil-knife: this pencil-knife adopts double blade at the structure of pencil; the different piece of separating the cutting pencil; the balanced cutting dynamics; pencil-lead is played good protective effect, and this pencil-knife is once finished the cutting of pencil, has continuous core; pen core is smooth neat; pencil is attractive and durable, fluent writing, characteristics such as environmental protection and saving.

The specific embodiment
Among the figure: 1, housing, 2, bellmouth, 3, the cutting pedestal, 4, cutting tip, 5, guide hole, 6, blade, 7, elastic plastic member, 8, displacement position-limiting.
In the drawings, in housing 1, have bellmouth 2, pencil layer of wood cutting tip 4 is installed on the cutting pedestal 3 at bellmouth 2 edges, pen core cutting tip 6 is installed on elastic plastic member 7, elastic plastic member 7 one ends are fixed on the housing base, and the other end is connected on the cutting pedestal 3.Leave displacement position-limiting 8 between blade 4 and 6, the distortion of bow type elastic plastic member provides the space during for the cutting pencil.The aperture of pen core guide hole 5 is consistent with the pen core diameter, behind the cutting layer of wood, separates pencil-lead, and pencil-lead is derived through guide hole, is cut by pencil-lead cutting tip 6 again.
Claims (4)
1, a kind of blade separate type pencil-knife, comprise housing, bellmouth, cutting pedestal and cutting tip, it is characterized in that on cutting pedestal (3), being provided with elastic plastic member (7), elastic plastic member (7) is the bow type, the one end is fixed on the base, the other end is connected on the cutting pedestal (3), bellmouth (2) center line one side at housing successively is equipped with blade (4) and (6), blade (4) is installed on the pedestal (3), blade (6) is fixed on the elastic plastic member (7), is provided with displacement position-limiting (8) between blade (4) and (6).
2, blade separate type pencil-knife according to claim 1 is characterized in that pen core cutting tip (6) and pencil-lead have certain cutting angle, and pen core is carried out the taper shape cutting.
3, blade separate type pencil-knife according to claim 1 is characterized in that pen core cutting tip (6) is fixed on the bow type elastic plastic member, can be with the outwards slight displacement of pressure.
