Abstract

The utility model relates to a multifunctional propelling pencil which can amend writing errors and correct improper pencil holding pose. The utility model completes the writing demand by attaching a propelling pencil on a pencil stand which is provided with an eraser. The telescoping of the propelling pencil can be completed under the action of a pencil holding forefinger and a spring which is arranged in a pencil sliding cavity of the pencil stand. Two screw threads, a male screw thread and a female screw thread, are arranged in an eraser telescopic cavity of the pencil stand. The male screw thread in the eraser telescopic cavity can be rotated by rotating a rotary spiral knob which is exposed out of the pencil stand in order that the female screw thread is driven to freely telescope along the inner wall of the eraser telescopic cavity, and then the length of the eraser exposed out of the pencil stand can be adjusted. If the writing errors generated in writing time need to be corrected, the pencil is drawn back by the pencil holding forefinger. After the errors are corrected by the eraser, the pencil holding forefinger is released and the propelling pencil is reverted in order to be used for writing continuously.

Description

Multi-functional propelling pencil

Affiliated technical field

The utility model relates to a kind of propelling pencil that can make amendment at once when finding clerical error, and has the user of correction pen holding posture function improperly.

Background technology

At present, existing common propelling pencil is write conveniently, but lacks the function of instant modification clerical error and correct user's pen holding posture function improperly.When the user produces clerical error, need to use the wrong instruments of other modifications such as extra rubber, use still not very convenient.In addition, user's pen holding posture not at that time, existing propelling pencil does not possess the function of correction.

Summary of the invention

For overcome existing common propelling pencil do not possess instant modification clerical error function defective and do not possess and correct user's pen holding posture defective improperly, the utility model provides a kind of propelling pencil.This propelling pencil is improved common propelling pencil to be installed in one be equipped with and can make on the flexible freely pencil frame of rubber, and can slide freely on frame.Propelling pencil slides backward so that expose rubber and revises mistake.By this improvement, made things convenient for user's instant demand of revising mistake when finding clerical error.The saddle forefinger that hold a pen groove and propelling pencil the place ahead of being fit to thumb and middle finger be set on the pencil frame in addition place that holds a pen makes user's finger be held in correct position with correct posture, reaches correction pen holding posture purpose improperly.

The technical scheme that its technical problem that solves the utility model adopts is: in order to increase the instant function of revising clerical error to propelling pencil, pencil frame that rubber is housed and improved propelling pencil are carried out reasonable combination.It below is elaboration respectively to pencil frame of the present utility model and improved propelling pencil.

The pencil frame is L shaped, and there are two holes the upper end, and preceding hole is communicated with the pencil sliding cavity, and the hole internal diameter slides freely with suitable propelling pencil inner sleeve and is advisable.Pencil sliding cavity inwall middle part is provided with three projecting points at interval, and projecting point is placed spring between supreme top, and spring can be by getting final product between three projecting points.Projecting point and spring limit the propelling pencil sliding scale.Pencil frame metapore is communicated with the rubber telescopic cavity, and the male and female screw device of push-and-pull rubber is housed in the rubber telescopic cavity.Pass metapore and the male thread that the top has three " product " fonts to give prominence in outstanding rotation spiral shell button of three " product " fonts and the rubber telescopic cavity is arranged with screw connection below.Rubber telescopic cavity inwall has three crossheadings, can not rotate with the control box thread, and it is flexible to be convenient to box thread crossheading under the traction of male thread simultaneously.The box thread lower end has three pawl legs to stretch unguiculus in rubber telescopic cavity crossheading, is used for the rubber of holding.The outside the place ahead of rubber telescopic cavity is an arc groove, is convenient to propelling pencil and slides in groove.In the groove below have one hook-shaped outstanding, pencil outer tube bar hole is enclosed within on the hook-shaped projecting point, propelling pencil is slided in limited range freely.The pencil frame is provided with the groove that holds a pen of being convenient to thumb, middle finger grasping respectively about the outside back lower place.

The external diameter of propelling pencil outer tube is slightly less than the internal diameter of pencil sliding cavity, and the upper end is provided with three crossheadings, slides between three projecting points in the pencil sliding cavity being adapted at.The forefinger place of holding a pen, the place ahead, pencil outer tube lower end is a saddle, holds a pen when both conveniently writing, the convenient again forefinger pencil of pulling back of revising when wrong.A bar hole is opened at rear, pencil outer tube lower end, is enclosed within on the hook-shaped projecting point of pencil frame below, has both played propelling pencil is fixed on effect on the pencil frame, makes things convenient for propelling pencil to slide in the groove of pencil frame again.

The beneficial effects of the utility model are, can produce when wrong finding to write, and revise easily immediately, and can proofread and correct user's pen holding posture improperly, and are simple in structure, convenient and practical.
