Abstract
The utility model discloses a composite pencil sharpener, comprising a base, a vertical blade, a plurality of arrayed blades and a screw. A conical bore is arranged in the base. The utility model is characterized in that the vertical blade and the arrayed blades are fixed in the two grooves of the base respectively through screw holes by the screw, the edge of the vertical blade is closely pressed on the tangent of the conical bore, the circular concave side of the arrayed blades is closely pressed on the conical end of the conical bore, the cutting mouths are arranged in the bore body of the conical bore and on the edges of the vertical blade and arrayed blades, the vertical blade is in a rectangular shape, and the edges of the arrayed blades are evenly arranged in a spiral shape. The utility model has the advantages of sharp cutting, unbreakable refill, low cost and portability.
Description
The utility model relates to a kind of pencil-knife, relates to specifically a kind ofly being fixed on pencil-knife on the same pedestal by two kinds of different cutters.
Existing pencil-knife has two types.The first kind is the blade type pencil-knife, and weak point is the pencil-lead that do not fracture in order to cut, and makes screw blade production technology and required precision height, the production cost height.Second class is the hand-rail type pencil-knife, and weak point is that volume is big, heavy, inconvenience is carried, production cost is higher, price is high.
Pencil-lead, combined type pencil-knife that cost is low fast, do not fracture when the purpose of this utility model provides a kind of the cutting.
In order to achieve the above object, the technical solution of the utility model is: a kind of combined type pencil-knife, by pedestal, the straight knife sheet, row's cutter, screw is formed, conical bore is arranged in the pedestal, it is characterized in that: straight knife sheet groove 11 and row's cutter groove 12 are arranged on the pedestal 1, the shape of straight knife sheet groove 11 and row's cutter groove 12 respectively with straight knife sheet 2, the shape of row's cutter 3 is corresponding, there is screw hole in straight knife sheet groove 11 central authorities, on pedestal 1 and row's cutter groove 12 vertical planes screw hole 7 is arranged and communicate with row's cutter groove 12, straight knife sheet 2, there is screw 7 in row's cutter 3 back side central authorities, straight knife sheet 2 is arranged in the straight knife sheet groove 11 and by screw 5 fixedlys connected with pedestal 1 by screw 7, fixedlys connected with pedestal 1 by screw 7 in row's cutter 3 row's of being arranged on cutter grooves 12 and by screw 5; The blade of straight knife sheet 2 is close on the tangent line of conical bore 4, row's cutter circular concave 10 of row's cutter 3 is close to the awl end parts of conical bore 4, there is cutting mouth 6 at the blade place of the blade of the hole body of conical bore 4 and straight knife sheet 2 and row's cutter 3, cutting mouthfuls 6 communicates with the hole of conical bore 4: straight knife sheet 2 is a rectangle, row's blade 9 of row's cutter 3 is that spirality is evenly distributed, and row's edge of a knife 8 is arranged between row's blade 9.
The blade cutting face close parallel of straight knife sheet 2 and row's cutter 3 is listed in the same side of the conical bore 4 of pedestal 1.
Since adopted said structure, the first, and the blade of straight knife sheet 2 is close on the tangent line of conical bore 4, is used to cut the wooden part of pencil, even blade weares and teares because of use, still can cut pencil when emergent, does not influence cutting effect.The second, the blade of row's cutter 3 is close to the awl end at conical bore 4, the carbon core part that is used to cut pencil, pencil-lead fast, does not fracture during cutting, this is that the cam cutter in the Hand pencil sharpener is improved to recessed flywheel knife, on the one hand, has not only kept its blade along tiltedly vertically multiple spot cutting of pencil-lead, and enlarged the contact-making surface of cutting, make the cutting effect of pencil-lead better, on the other hand, cam cutter that will be bigger is improved to very little recessed flywheel knife, save raw material greatly, reduced production cost.The 3rd, both effectively combined the cutting principle of hand-rail type pencil-knife and blade type pencil-knife, kept the volume of blade type pencil-knife again, saved raw material on the one hand, reduced cost, easy to carry on the other hand.
Below in conjunction with each accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model embodiment 1 structural front view.
Fig. 2 is the utility model straight knife chip architecture schematic diagram.
Fig. 3 is the utility model row cutter side structure schematic diagram.
Fig. 4 is the utility model row cutter Facad structure schematic diagram.
Fig. 5 is the utility model embodiment 2 structural front view.
1-pedestal wherein, 2-straight knife sheet, 3-row cutter, 4-conical bore, 5-screw, 6-cutting mouthful, 7-screw, 8-edge of a knife, 9-blade, 10-row cutter circular concave, 11-straight knife sheet groove, 12-row cutter groove.
Most preferred embodiment 1: as shown in Figure 1, the utility model is by pedestal 1, straight knife sheet 2, row's cutter 3, screw 5 is formed, pedestal 1 is three-dimensional trapezoidal, straight knife sheet groove 11 and row's cutter groove 12 are arranged on the pedestal 1, the shape of straight knife sheet groove 11 and row's cutter groove 12 respectively with straight knife sheet 2, the shape of row's cutter 3 is corresponding, there is screw hole in straight knife sheet groove 11 central authorities, on pedestal 1 and row's cutter groove 12 vertical planes screw hole is arranged and communicate with row's cutter groove 12, straight knife sheet 2, there is screw 7 in row's cutter 3 back side central authorities, straight knife sheet 2 is arranged in the straight knife sheet groove 11 and by screw 5 fixedlys connected with pedestal 1 by screw 7, fixedlys connected with pedestal 1 by screw 7 in row's cutter 3 row's of being arranged on cutter grooves 12 and by screw 5; The blade of straight knife sheet 2 is close on the tangent line of conical bore 4, and row's cutter circular concave 10 of row's cutter 3 is close to the awl end parts of conical bore 4, and there is cutting mouthfuls 6 at the blade place of the blade of the hole body of conical bore 4 and straight knife sheet 2 and row's cutter 3, and cutting mouth 6 communicates with the hole of conical bore 4; Straight knife sheet 2 is a rectangle, and row's blade 9 of row's cutter 3 is that spirality is evenly distributed, and row's edge of a knife 8 is arranged between row's blade 9.
