Abstract
The utility model discloses a pencil sharpener which is composed of a clamp body and a sharpener body. The clamp body is made into a cylinder body which is matched with the outer diameter of a pencil and an inner wall is provided with screw threads. The surface of the edge of the sharpener body is a spiral shape and a slot is arranged between the edge and a knurling mouth. When the pencil is sharpened, the pencil is extended into the sharpener body from the position of the clamp body and is propelled inwards by the screw threads of the clamp body and the spiral edge. A penholder and a pencil core which are arranged in the sharpener body are ground by the knurling mouth. Wooden chips are chipped by the edge and are discharged from the slot out of the sharpener body. The utility model has the advantages of simple structure. When the pencil is sharpened, force is small and homogeneous and the pencil core can not be broken.
Description
The utility model belongs to the stationery class, belongs to the penknife class particularly.
The cutter that sharpens a pencil has a lot, though the profile different modeling has aesthetic feeling, blade is a strip blade, and cutting edge is a straight line.When adopting this class cutter to sharpen a pencil, because blade is parallel with pen, pen one side is stressed, and the power of cutting is upright impact cutting power, the pen core frangibility.Simultaneously when cutting, cut the vigour of style in literary composition and the depth of cut entirely with hand-power control, excessive slightly, too quickly as power, cause the depth of cut big, impact cutting power is not enough, causes pen core to fracture.
The purpose of this utility model is according to the existing deficiency of above-mentioned penknife, is intended to design the penknife that a kind of power of cutting is sliding cutting power.Penknife is simple in structure, and it is laborsaving to cut pen, and firmly evenly, pen core is frangibility not.
The purpose of this utility model realizes that in the following manner penknife is made of clamp 1 and cutter hub 2.The cylindrical shell of clamp for matching with an external diameter, the inwall car has screw thread, and cutter hub is a cone, and cutting edge limit 3 and annular knurl mouth limit 5 be shape in the shape of a spiral, and there is slot 4 centre.Edge limit and centreline space are 45 ° of angles.Circular hole 6 is arranged at the cone bottom.
The utility model is described with reference to the accompanying drawings.
Fig. 1 the utility model structural representation
Fig. 2 cutter hub 2 launches schematic diagram
With reference to accompanying drawing, the utility model is made of clamp 1 and cutter hub 2, and the two can be processed as one, or fastens as one.Clamp inwall car has screw thread.Cutter hub is a cone, and cutting edge limit 3 on the cone and annular knurl mouth limit be shape in the shape of a spiral.Edge limit and centreline space are 45 ° of angles.
When cutting, pen is stretched into by clamp, spirality advances, and when treating that pencil contacts with edge, promptly pen is cut.Screw thread by annular knurl mouth inwall institute car grinds penholder in the cutter and pen core earlier, and the wood chip that cuts is discharged from the slit.Because the utility model is that a spirality is advanced inwards when cutting, and is both laborsaving, and strength is easy to control, can be not excessive or too quickly, so pen core can not fracture.
The utility model is simple in structure, and is cheap, easy to use, and it is little and even to exert oneself, and pen core can not fracture.
