Abstract
The utility model provides a pencil cutting knife with double purposes comprising a casing, a cutting blade, and a screw. The cutting blade is fixed on the casing via the screw; the casing has a pencil holding through-hole, wide at the outer part and narrow at the inner part; the cutting blade is arranged in slope along the through hole and the bottom of the casing is provided with a bar-type insertion socket in perpendicular to the axes of the through hole; the insertion socket and the cutting blade intersect at the tail end of the cutting blade; the pencil cutting knife with double purposes further include an insertion sheet corresponding to the insertion socket, and the insertion sheet is provided with a notch. When the insertion sheet is inserted into the insertion socket, the notch on the insertion sheet falls right to the middle of the through hole. The pencil cutting knife can be used to cut not only sharp pencil heads but also thick and round pencil heads as well, thereby meeting different requirements.
Description
Technical field
The utility model relates to a kind of stationery, especially a kind of dual-purpose penknife.
Background technology
Present penknife has various surface structure, yet its actual workpiece and the course of work are identical, the blade that a slice tilts is set in the penknife, its edge of a knife starting point is on the edge, circular section of pencil, the terminal point of the edge of a knife is on the axis of pencil, when sharpening a pencil, pencil is sent in the hole of pencil-knife while rotating gradually, arrive the blade terminal point up to the pencil termination, this moment, pencil was by the point that disappears, yet pencil is not used for writing many times, as scribbles answering card, the fine arts are drawn, draw and indicate line or the like, they all need more slightly but more mellow and fuller pencil stub, common penknife or cut out sharp-pointed pencil stub, or cut out sharp-featured round table surface pencil stub, can't satisfy above-mentioned requirement.
Summary of the invention
At the problems referred to above, the purpose of this utility model is to provide a kind of dual-purpose penknife, and this dual-purpose penknife not only can be cut out sharp-pointed pencil stub, and can cut out thick and mellow and full pencil stub, to satisfy various needs.
The technical scheme that its technical problem that solves the utility model adopts is: this dual-purpose penknife comprises housing, blade, screw, blade is fixed on the housing by screw, has the type through hole wide outside and narrow inside that can hold pencil on the housing, blade is skewed setting along described through hole, the bottom of described housing is provided with the bar shaped socket one, described socket is perpendicular to the axis of described through hole, described socket and blade intersect at the tail end of blade, described dual-purpose penknife also comprises the inserted sheet that matches with socket, described inserted sheet is provided with a recess, when inserted sheet insertion socket matched with it, the recess on the inserted sheet was positioned at the through hole middle.
As preferably, described inserted sheet is a rectangular metal sheet, and described recess is the coarse recess of hemispherical, and sphere diameter is 1mm-3mm.
The beneficial effects of the utility model are: this dual-purpose penknife takes off inserted sheet when fining away sharp pencil stub, pushes while pencil rotated in through hole, gets final product until arriving at the through hole bottom; When cutting thick and mellow and full pencil stub, inserted sheet is inserted in the socket, push while also pencil is rotated in through hole, until the recess that arrives at inserted sheet, then recess is worn into thick and mellow and full shape with pencil stub.This dual-purpose penknife not only can be cut out sharp-pointed pencil stub, and can cut out thick and mellow and full pencil stub, to satisfy various needs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of inserted sheet in the utility model.
Coding among the figure is respectively: 1 is housing; 2 is blade; 3 is screw; 4 is through hole; 5 is socket; 6 is inserted sheet; 7 is recess.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
As shown in Figure 1, this dual-purpose penknife comprises housing 1, blade 2, screw 3, blade 2 is fixed on the housing 1 by screw 3, has the type through hole 4 wide outside and narrow inside that can hold pencil on the housing 1, blade 2 is skewed setting along described through hole 4, the bottom of described housing 1 is provided with bar shaped socket 5 one, described socket 5 is perpendicular to the axis of described through hole 4, described socket 5 and blade 2 intersect at the tail end of blade 2, described dual-purpose penknife also comprises the inserted sheet 6 that matches with socket 5, described inserted sheet 6 is provided with a recess 7, and when inserted sheet 6 inserted socket 5 and matches with it, the recess 7 on the inserted sheet 6 was positioned at the middle of through hole 4.
Above-mentioned dual-purpose penknife, described inserted sheet 6 is a rectangular metal sheet, and described recess 7 is the coarse recess of hemispherical, and sphere diameter is 1mm-3mm.
Above-mentioned dual-purpose penknife when fining away sharp pencil stub, takes off inserted sheet 6, pushes while pencil rotated in through hole 4, gets final product until arriving at through hole 4 bottoms; When cutting thick and mellow and full pencil stub, inserted sheet 6 is inserted in the socket 5, push while also pencil is rotated in through hole 4, until the recess 7 that arrives at inserted sheet 6, then recess 7 is worn into thick and mellow and full shape with pencil stub.This dual-purpose penknife not only can be cut out sharp-pointed pencil stub, and can cut out thick and mellow and full pencil stub, to satisfy various needs.
