Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an improvement of the nozzle type sharpener pencil, particularly the tip pipe slide type cap.

(Prior Art) As shown in Fig. 1, a pipe-slide type sharpening pencil has a tip pipe 1 that contacts the paper surface when writing and allows writing while being pushed backwards. Covering as much as possible has the advantage of preventing breakage of the lead 2 and extending the writing distance of the lead 2 with one knock.

(Problem to be solved by the invention) However, since the paper surface is constantly rubbed, it has the drawback of impairing the feel of the brush and damaging the paper surface. SUMMARY OF THE INVENTION An object of the present invention is to provide a base for a sharpening pencil that overcomes these drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the base of the sharpening pencil according to the present invention is provided with a base of a sharpening pencil equipped with a slidable tip pipe of a pipe slide type. Furthermore, at the tip, there is a thin linear body that has elasticity to prevent buckling or complete bending when the tip pipe retreats during writing, rigidity to the extent that it does not damage the paper surface, and wear resistance. The pipe is fixed in such a way that it protrudes outward from the tip of the tip pipe.

(Function) Since the linear body is interposed between the tip pipe and the paper surface when writing, direct contact of the tip pipe with the paper surface is avoided, improving the writing feel and preventing damage to the paper surface. .

(Example) Hereinafter, an example of the present invention will be described based on the drawings. First, FIG. 2 shows the first embodiment, in which a tip pipe 1 that can be slid freely, in other words, can come out and go freely is attached to the tip, and a length of about the core diameter is attached to the end surface of the tip pipe 1. A plurality of thin linear bodies 3 made of carbon fiber having a diameter are fixed to each other. This linear body 3 has elasticity that does not cause buckling or complete bending when the tip pipe 1 retreats during writing, rigidity that does not damage the paper surface, and wear resistance that can withstand long-term use. Must be.

Next, FIG. 3 shows a second embodiment of the present invention, in which a linear body 3 is fixed to the outer peripheral surface of the tip pipe 1. This second embodiment has the advantage that the linear body 3 can be easily fixed as compared to the first embodiment.

Furthermore, FIG. 4 shows a third embodiment, in which a step 4 is formed near the tip of the tip pipe 1, and a linear body 3 is fixed to the step 4. This third embodiment has the advantage of better appearance than the second embodiment.

[Effect of idea]

The present invention is as described above, and when writing, the tip of the tip pipe does not come into direct contact with the paper surface, but instead, the thin elastic linear body comes into contact with the paper surface and pushes the tip pipe up and back. Therefore, the disadvantages such as impairing the writing feel and damaging the paper surface are eliminated, and the advantages of the pipe slide method are maintained.
