Abstract
The embodiment of the invention discloses a kind of pencil-knife making pencil mutually assemble prolongation, including pencil-knife body, described pencil-knife body has conical cavity, and described pencil-knife body surface has the cutter groove connecting described conical cavity, and a trough rim of described cutter groove is set to cut the cutter head of pencil；The nib that also has described pencil-knife body cuts chamber, and described nib cuts cavity wall tool and is provided with and cuts threaded walls, described in cut the threaded walls internal diameter diameter less than described conical cavity；Described pencil-knife body of stating also has a tail and cuts chamber, and described tail cuts to be provided with on the central axis of chamber and cut screw thread cutter head, described in cut the diameter of screw thread cutter head and described to cut threaded walls internal diameter consistent.Use the present invention, the nib of pencil can be carried out the cone shape purpose cutting and reaching to write, when pencil is depleted to certain length, pencil head end and tail end can be cut, and it is fixed assembling by internal and external threads, reach the effect extended, thus avoid unnecessary waste, save resource.
Description
Technical field
The present invention relates to a kind of pencil-knife, particularly relate to a kind of pencil-knife making pencil mutually assemble prolongation.
Background technology
Pencil is a kind of conventional cultural office.Along with the use of pencil, pencil can become shorter and shorter, existing
The general a length of 17-21cm of pencil, when be only left 5-7cm long when, due to the shortest and when cannot grasp, typically
Will lose, cause certain wasting of resources.Although existing pencil elongated instrument in prior art, and it uses fiber crops
Tired, and add use cost, there is also another kind in prior art is remaining for use pencil stub to interleave merging two-by-two lead to
Crossing white glue with vinyl to be fixed, there is various inconvenience in it on using, and does not has relevant pencil-knife can make lead in existing prior art
Pen mutually carries out assembling extending.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, it is provided that a kind of pencil making pencil mutually assemble prolongation
Cutter.The shape that pencil can cut into adaptation carries out extending assembling.
In order to solve above-mentioned technical problem, embodiments provide a kind of pencil making pencil mutually assemble prolongation
Cutter, including pencil-knife body, described pencil-knife body has conical cavity, and described pencil-knife body surface has the described circular cone of connection
The cutter groove in chamber, a trough rim of described cutter groove is set to cut the cutter head of pencil；Described pencil-knife body also has nib and cuts chamber,
Described nib cuts cavity wall tool and is provided with and cuts threaded walls, described in cut the threaded walls internal diameter diameter less than described conical cavity；Institute
Stating pencil-knife body also to have a tail and cut chamber, described tail cuts to be provided with on the central axis of chamber and cuts screw thread cutter head, institute
It is coniform for stating and cutting the front end of screw thread cutter head, described in cut the diameter of screw thread cutter head and described to cut threaded walls internal diameter consistent.
Wherein, described chasing wall front end oral area bore is little by big gradual change.
Wherein, cutting threaded walls described in is that multistage is symmetrical arranged.
Wherein, cutting screw thread cutter head described in is that multistage is symmetrical arranged.
Wherein, it is consistent that described nib cuts chamber, a tail cuts the degree of depth in chamber.
Wherein, described conical cavity, nib cuts chamber, a tail cuts chamber and is arranged on described pencil-knife body not coplanar.
Wherein, described pencil-knife body is that ceramic material is one-body molded.
Implement the embodiment of the present invention, have the advantages that the present invention can carry out cone shape cutting to the nib of pencil
Cut the purpose reaching to write, when pencil is depleted to certain length, can be combined cutting to pencil head end and tail end, and pass through
Internal and external threads is fixed assembling, reaches the effect extended, thus avoids unnecessary waste, has saved resource.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is made into one
Step ground describes in detail.
With reference to the structural representation shown in Fig. 1, Fig. 2 and Fig. 3.
A kind of pencil-knife making pencil mutually assemble prolongation of the present invention, including pencil-knife body 1, pencil-knife body 1
There is conical cavity 10, cut for normally writing, the upper surface of pencil-knife body 1 has cutter groove 11, cutter groove 11 connection circle
Cone chamber 10, the trough rim 12 at cutter groove 11 directly forms the cutter head for cutting pencil writing head end, structural representation as shown in Figure 4
Figure.
Pencil-knife body 1 also has nib and cuts chamber 20, cuts to be provided with on the inwall of chamber 20 in nib and cuts threaded walls 21,
Cut the internal diameter diameter less than conical cavity 10 of threaded walls 21, and in order to smoothly pencil head end be cut into screw-shaped head
End 22, structural representation as shown in Figure 5, cuts threaded walls 21 front end oral area bore little by big gradual change, makes lead head end be smoothed out
Cut, and form cylindric or coniform thread head, be for columned screw thread head end in the present embodiment.
Pencil-knife body 1 also has a tail and cuts chamber 30, and a tail cuts to be provided with on the central axis in chamber 30 and cuts screw thread
Cutter head 31, in order to dig out the thread cavity 32 originally mated with above-mentioned screw thread head end, as it is shown in figure 5, cut screwer to pencil tail end
The front end of 31 is coniform, and the overall diameter cutting screw thread cutter head 31 is consistent with cutting threaded walls 21 internal diameter.
The head end of two sections of pencils and tail end cut chamber 20 respectively through conical cavity 10, nib, a tail cuts after chamber 30 cuts,
Can be fixedly connected with thread cavity forming the screw-shaped head end being connected, reach to extend the purpose of pencil length.
More optimizedly, cut threaded walls 21 and cut screw thread cutter head 31 and be symmetrical arranged in multistage, being in the present embodiment
Four sections are symmetrical arranged.
In order to make screw-shaped head end the most identical with thread cavity, nib cuts chamber 20, a tail cuts the degree of depth in chamber 30
Unanimously.
Certainly, conical cavity 10, nib cut chamber 20, a tail cuts chamber 30 and can be arranged as required on the same face or different
On face, in the present embodiment, not coplanar it is preferably.
In order to make the present invention the exquisitest and environmental protection, the present invention generally ceramic material is one-body molded.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.Right
For those of ordinary skill in the field, can also make on the basis of the above description other multi-form change or
Variation.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or
Change among still in the protection domain of the invention.
