Abstract

The invention relates to a helmet type pencil sharpener. The helmet type pencil sharpener comprises a sharpener cover shaped like a motorcycle helmet and a round base fixed to the lower end of the sharpener cover. Two pencil sharpening cutter bases are arranged inside the base side by side, and an open hole is correspondingly formed in each pencil sharpening cutter base and is communicated with the corresponding pencil sharpening cutter base. An arc-shaped open groove is formed in the part, opposite to the rear sides of the open holes, of the sharpener cover, an arc-shaped stopping frame movably fixed to the sharpener cover is arranged on the outer side of the arc-shaped open groove, and a stopping block capable of moving vertically is arranged in front of the open holes. According to the helmet type pencil sharpener, the time of pouring out pencil shavings can be saved, and the pencil shavings generated in the pencil sharpening process can be automatically pushed backwards and discharged from a window; a hole cover capable of moving vertically is arranged on a pencil hole, and therefore a blade does not get blunt. The helmet type pencil sharpener has the advantages that the service life is prolonged, and the pencil shavings can be discharged conveniently.

Description

A kind of helmet-type pen plane

Technical field

The invention belongs to pencil pen plane technical field, relate to a kind of helmet-type pen plane.

Background technology

Pen plane is that a kind of being used for considers the pen of pencil to be worth doing cut a kind of specific purpose tool, the speed of cutting is improve relative to traditional penknife, decrease penknife simultaneously and easily cut problem in one's hands, cut the effect of out nib than original also more beautiful and clean, and the result of use of pen core is better, but existing pen digs shape and structure is too single, and also do not possess attraction as the article that children often use, and existing pen plane is all that employing is split type, need separately when pen bits are filled in inside, pen bits are poured out and extremely bothers, and a hole of cutting pen is directly exposed to outside and easily causes blade to make moist the problem such as aging.

Summary of the invention

In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of helmet-type pen plane, it offers a movable discharging window at the rear side of Pencil-sharpening razor blade, thus the pen bits that can cut out in the process of cutting pen can be discharged along the mode pushed backward from window voluntarily, on a hole, be provided with up and down port lid simultaneously, thus ensure that blade can not rust, there is the features such as the discharge increasing the service life, facilitate pen bits.。

The technical solution adopted for the present invention to solve the technical problems is: a kind of helmet-type pen plane, comprise one in motorcycle helmet shape plane lid and be fixed on plane lid lower end cup dolly, two penknife seats are side by side provided with in base, each penknife seat correspondence is provided with a coupled logical perforate, opposite plane on rear side of perforate covers, and is provided with an arc-shaped groove, then be provided with one outward at arc-shaped groove and be movably fixed to the arc gear frame digging and cover, be then provided with the block that can move up and down in perforate front end.

The plane that the both sides of described arc gear frame are fixed on arc-shaped groove both sides by continuously connected fastener covers.

Described arc gear frame with arc-shaped groove is provided with corresponding fin and groove thus ensure both compact siro spinning technology.

The invention has the beneficial effects as follows: the time that the bits of falling pen can be saved by this plane, in the process of cutting pen, cut out the pen bits come can discharge along the mode pushed backward from window voluntarily, on a hole, be provided with up and down port lid simultaneously, thus ensure that blade can not rust, there is the features such as the discharge increasing the service life, facilitate pen bits.

Accompanying drawing explanation

Fig. 1 is stereogram of the present invention;

Fig. 2 is rearview of the present invention.

In figure: 1-base, 2-digs lid, 3-penknife seat, 4-perforate, 5-arc-shaped groove, 6-arc gear frame, 7-block, 8-fin, 9-groove.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further described.

See Fig. 1, a kind of helmet-type pen plane, comprise one in motorcycle helmet shape plane lid 2 and be fixed on plane lid 2 lower end cup dolly 1, two penknife seats 3 are side by side provided with in base 1, each penknife seat 3 correspondence is provided with a coupled logical perforate 4, opposite plane lid 2 on rear side of perforate 4 is then provided with an arc-shaped groove 5, outside arc-shaped groove 5, be then provided with an arc gear frame 6 be movably fixed on plane lid 2, be then provided with the block 7 that can move up and down in perforate 4 front end.

The both sides of described arc gear frame 6 are fixed on the plane lid 2 on arc-shaped groove 5 both sides by continuously connected fastener.

Described arc gear frame 6 with arc-shaped groove 5 is provided with corresponding fin 8 and groove 9 thus ensure both compact siro spinning technology.

The present invention can save the time of the bits of falling pen by this plane, in the process of cutting pen, cut out the pen bits come can discharge along the mode pushed backward from window voluntarily, on a hole, be provided with up and down port lid simultaneously, thus ensure that blade can not rust, there is the features such as the discharge increasing the service life, facilitate pen bits.

Claims

1. a helmet-type pen plane, comprise one in motorcycle helmet shape plane lid and be fixed on plane lid lower end cup dolly, it is characterized in that: in base, be provided with two penknife seats side by side, each penknife seat correspondence is provided with a coupled logical perforate, opposite plane on rear side of perforate covers, and is provided with an arc-shaped groove, then be provided with one outward at arc-shaped groove and be movably fixed to the arc gear frame digging and cover, be then provided with the block that can move up and down in perforate front end.

2. helmet-type pen digs as claimed in claim 1, it is characterized in that: the plane that the both sides of described arc gear frame are fixed on arc-shaped groove both sides by continuously connected fastener covers.
