Description

Pencil capable of improving holding stability

Technical Field

The utility model relates to a stationery, especially a pencil that improves and hold a stability.

Background

A Pencil (qi ā n b ǐ, Pencil) is a special pen for writing and drawing sketch, and has a history of more than four hundred years from now, wherein the Pencil for drawing sketch is divided into various types, which are divided into three development stages, namely graphite, a wooden penholder and a Pencil with a cap, and in addition, the color of the Pencil is red and white, black and white, yellow and black stripes and the like; the existing pencil is generally cylindrical and hexagonal prism-shaped, the cylindrical pencil is very easy to slide due to the fact that the section of the cylindrical pencil is circular, and therefore stability is poor when the pencil is used for writing, although the stability of writing of the hexagonal prism-shaped pencil is greatly improved, edges and corners are supported in a back-rest area of a hand, writing time is long, the phenomenon of friction and abrasion is easily caused, and long-term writing, drawing and other operations of the pencil are not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve above-mentioned prior art's shortcoming, provide one kind can write stability good and can not cause to use the pencil that an improvement held a stability of buffing wearing and tearing condition emergence for a long time to write the person, satisfied the user write stability good and can not cause the hand lean against the demand that supports regional wearing and tearing.

The utility model provides a technical scheme that its technical problem adopted: the pencil capable of improving the holding stability comprises a circular pencil holder and a pencil core arranged in the circular pencil holder, wherein a pair of axial cutting planes symmetrically arranged along the center of the circular pencil holder are arranged on the circular pencil holder, an included angle is formed between the two axial cutting planes, and the sum of the distances from the two axial cutting planes to the axis of the circular pencil holder is smaller than the diameter of the circular pencil holder. The axial cutting planes have the effects that a thumb and an index finger of a user can press the axial cutting planes to play a role in writing stability and avoid the pencil from rotating during writing; the included angle between the two axial cutting planes is suitable for the pressing angle of the thumb and the forefinger (as shown in fig. 4).

Further perfecting, a group of ring-shaped grooves which are distributed at intervals along the axial direction of the round pen holder are arranged on the round contour surface of the round pen holder. The ring-shaped groove here has the effect of increasing the friction, so that the stability is higher when the pencil is used.

Further perfection, the top end of the round pen holder is spherical. The spherical arrangement here has the effect that the top end of the circular pen holder is lubricated to avoid poking a user or outsiders.

Further perfection, the angle between the two axial cutting planes is 64 degrees. The effect of the 64 ° angle between the two axial cutting planes is here that this angle is just such that the thumb and forefinger of the user can easily grip the two axial cutting planes, resulting in a higher stability and comfort when writing with a pencil (see fig. 4).

Further perfecting, the contour lines of the round penholder and the ring-shaped grooves are all arranged in a rounding way. The rounded corners here have the effect of avoiding scraping and stabbing of the user and outsiders.

The utility model discloses profitable effect is: the utility model has the advantages of ingenious and reasonable structural design, utilize axial cutting plane can make user's thumb and forefinger press on both axial cutting plane, play and write stabilizing effect, avoid the pencil when writing, take place rotatory effect, utilize the diaxon to be the effect that the contained angle set up between the cutting plane, can be adapted to the angle when thumb and forefinger press, the utility model discloses can make the pencil when writing not only stability high, but also can not adversary's pencil lean against the regional wearing and tearing of support, do benefit to the long-time stability of writing the person, draw, be worth popularizing and applying.

Description of reference numerals: the pencil comprises a circular pencil holder 1, an axial cutting plane 1-1, a circle-shaped groove 1-2, a spherical surface 1-3, a fillet 1-4, a pencil lead 2, a hand 3, a pencil back support area 3-1, a thumb 3-2 and a forefinger 3-3.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and for simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

With reference to the accompanying drawings: the pencil capable of improving the stability of holding the pencil comprises a circular pencil holder 1 and a pencil lead 2 arranged in the circular pencil holder 1, wherein the circular pencil holder 1 is provided with a pair of axial cutting planes 1-1 which are symmetrically arranged along the center of the circular pencil holder 1, and an included angle is formed between the two axial cutting planes 1-1.

The circular outline surface of the circular pen holder 1 is provided with a group of ring-shaped grooves 1-2 which are distributed at intervals along the axial direction of the circular pen holder 1.

The top end of the round penholder 1 is spherical 1-3.

The angle between the two axial cutting planes 1-1 is 64 deg..

The contour lines of the round penholder 1 and the ring-shaped grooves 1-2 are rounded 1-4.

The working principle of the utility model is that when writing, a person 3 holds the thumb 3-2 and the forefinger 3-3 of the person 3 in the plane of the two axial cutting planes 1-1 by pinching, then, the circular pen holder 1 leans against the pencil back support area 3-1, writing is carried out in this way, the stability is good, and the circular surface of the circular pen holder 1 leans against the pencil back support area 3-1 (as shown in figure 4), and the long-time writing can not generate friction wear to the pencil back support area 3-1 like the traditional hexagonal prism-shaped pencil, so that the pencil is more comfortable, is beneficial to the long-time stable writing and drawing of a user, and is worthy of popularization and application. The loop-shaped recess 1-2 can here further increase the stability of the pencil against the pencil rest support region 3-1.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
