Description

Pencil

Technical Field

The utility model relates to a stationery technical field specifically is a pencil.

Background

The pencil is a special learning tool for writing and drawing sketch, and has a history of more than four hundred years to date, wherein the pencil for drawing sketch is divided into various types, namely graphite, a wooden penholder and a pencil with a cap; in addition, the color of the pencil has red and white, black and white, yellow and black stripes and the like, and the pencil is one of the longest-used pen stationery in daily work, study and life, is convenient to use and easy to modify, and is convenient to apply to drawing and writing occasions.

The combination degree of pencils and erasers on the market is low, and the common erasers are inconvenient to erase details, so that the pencils and the erasers are frequently erased by mistake during drawing and writing; in daily study or work, when drawing or measuring sizes are often encountered, a ruler cannot be found at any time, and study or work is delayed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a pencil to solve the problems that the combination degree of the pencil and the eraser provided in the background technology is low, and the common eraser is inconvenient to erase details, so that the pencil often erases the details by mistake when drawing and writing; when drawing or measuring the size, the ruler can not be found at any time, and the problem of study or work is delayed.

In order to achieve the above object, the utility model provides a following technical scheme: a pencil comprises a pencil core and a proportional scale, wherein a sharpening type eraser core is fixed at the end of the pencil core, a pencil holder is bonded on the outer wall of the sharpening type eraser core, and the proportional scale is bonded on the outer wall of the pencil holder.

Preferably, the refill is cylindrical, the shape and the structure of the refill are matched with those of the shakable eraser core, and the refill and the shakable eraser core are symmetrical about the center of the penholder.

Preferably, the penholder is in a round-corner prism shape, and the refill, the sharpenable eraser core and a vertical central axis of the penholder are coincided.

Preferably, the outer wall of the penholder is tightly attached to the inner wall of the scale, and the penholder is hollow.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the pen core at one end is convenient to write and draw; one end can cut formula eraser core, conveniently sharpens, erases, revises the detail, and furthest reduces because of the mistake is wiped, the inconvenience that causes more, improves work and learning efficiency, and double-end refill design simultaneously, furthest reduces the inconvenient use that any one end of pencil end or eraser end caused because of cutting the weak point and produces whole a pencil unnecessary extravagant, makes moreover the utility model discloses a pencil is a multi-purpose, and the design of many unifications lets the user reduce the encumbrance because of carrying too much instrument and bringing.

2. Make things convenient for various age layer users to hold the pen with pen-holder fillet prismatic structure to place and be difficult for rolling on the desktop isoplanar and drop, under the unchangeable circumstances of whole size, the side is the cambered surface, and reducible pen-holder's materials is favorable to reduce cost simultaneously.

3. With the scale and the scale of each side of pen-holder, the person of facilitating the use can measure scale and proportion at any time, improves work and learning efficiency, and the scale is 0 scale from the pen-holder middle-end simultaneously, and toward both ends increase progressively, and the number is for the mirror image handstand each other about, lets the user see at which end the scale all be positive number to do not influence 0 scale initial measurement when cutting the pencil.

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.

Referring to fig. 1-4, the present invention provides a technical solution: a pencil comprises a pencil lead 1, a sharpenable rubber core 2, a penholder 3 and a scale 4, wherein the sharpenable rubber core 2 is fixed at the end of the pencil lead 1, the penholder 3 is bonded on the outer wall of the sharpenable rubber core 2, and the scale 4 is bonded on the outer wall of the penholder 3.

The pen core 1 is cylindrical, the shape and structure of the pen core 1 are matched with those of the shapable eraser core 2, and the pen core 1 and the shapable eraser core 2 are symmetrical about the center of the pen holder 3; the one-end can sharpen the type eraser core 2, facilitate sharpening, erase, revise the detail, reduce the inconvenience caused by mistake erasing, multiple erasing to the maximum extent, raise work and study efficiency, the design of the double-end refill, reduce the pencil end or eraser end any end of end produce the unnecessary waste of the whole pen because of cutting the inconvenient use caused by short to the maximum extent at the same time, and make the utility model discloses a pencil is multi-purpose, the design of unifying more, let users reduce the encumbrance brought because of carrying too much tools;

the pen holder 3 is in a round-corner prism shape, the pen core 1, the shapable eraser core 2 and the vertical central axis of the pen holder 3 are coincided, the round-corner prism structure of the pen holder 3 is convenient for users at various age groups to hold pens, the pen holder is not easy to roll and drop when being placed on a desktop plane and the like, and meanwhile, under the condition that the whole size is not changed, the side surface is an arc surface, so that the material consumption of the pen holder 3 can be reduced, and the cost is reduced;

the outer wall of pen-holder 3 is closely laminated in the inner wall of scale 4, and pen-holder 3 is the cavity form, scale and scale 4 of 3 each sides of pen-holder are with this design, the person of facilitating the use can measure scale and proportion at any time, improve work and learning efficiency, scale 4 is 0 scale from 3 middle-ends of pen-holder simultaneously, increase progressively toward both ends, the figure each other stands upside down for the mirror image about, let the user no matter which end sees the scale all be positive figure, and do not influence 0 scale initial measurement when cutting the pencil.

The working principle is as follows: for the pencil, firstly, the shell of the penholder 3 at one end is cut to expose the refill 1, then a user holds the penholder 3 with a rounded prism structure, the pencil can be conveniently held by users at various age groups, the pencil is placed on a desktop and the like plane and is not easy to roll and fall off, the exposed refill 1 plays a role in writing expression and meets the requirement of daily use expression, then, the outer wall of the penholder 3 is adhered with a scale 4, the scale 4 is 0 scale from the middle end of the penholder 3 and increases towards two ends, the left number and the right number are mirror images and inverted, so that the user can see the scale at any end as the front number to meet the requirement of accurate measurement of the user, when writing is wrong, the shell of the penholder 3 at the other end can be cut to expose the cuttable eraser core 2 to meet the requirement of changing and erasing wrong contents during writing, the whole pencil using process is completed in this way.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
