Description

A kind of propelling pencil

Technical field

This utility model belongs to stationery field, is specifically a kind of propelling pencil.

Background technology

Pencil is the important writing implement of current students pupil in the lowest end of the year, has low price, correction The advantage such as convenient, writing, draw, paint in there is extensive use.The pencil that student uses at present mainly has shell to be wood Fixed core pencil and the mobilizable propelling pencil of pencil-lead.Fixed core pencil simple in construction, unit price are low, but its shell is main For wooden, also cannot move between pencil-lead and shell, when needing knockout after pencil uses a period of time, need core periphery Layer of wood ream, the needs that sharpen a pencil take a substantial amount of time, and also can produce the waste materials such as lead for retractable pencil powder, wood flour, expend substantial amounts of Timber resources, is unfavorable for the protection of environment.And the mobilizable propelling pencil of pen core typically has the structures such as the shaft of a writing brush, nib, the cap for brush, Pen core outside than point consume fast complete time, it is only necessary to press the cap for brush up and down, knockout can be realized, presently, there are simultaneously in writing process Can the propelling pencil of automatic propelling, but howsoever, when the pencil-lead within the shaft of a writing brush runs out of, being required for opening the cap for brush will be new Pen core is loaded into.On the one hand propelling pencil rapid wear frangibility, frequently changes core, elapsed time during using；On the other hand, change Staff pencil-lead to be touched during core, pencil-lead is a kind of noxious substance, change core complete after will wash immediately Hands, uses highly inconvenient, even has the danger of poisoning.

Summary of the invention

The purpose of this utility model is: for needing in prior art manually frequently to change core, it is provided that a kind of propelling pencil, Can in use need not contact pen core by staff, realize fast quick change core, convenient use simultaneously.

The technical solution adopted in the utility model is as follows:

The utility model discloses a kind of propelling pencil, including penholder, nib, central canal, thimble, thimble shell, handle, Storage core cavity, described nib is positioned at the tip of penholder, and central canal is positioned at inside penholder, and described storage core cavity is positioned at outside central canal and penholder Between shell, central canal end is provided with thimble, and thimble is socketed with central canal, and thimble end is cased with thimble shell, and handle is positioned at top On pin shell, casing is connected on pen arm end.Existing automatic propelling structure during wherein nib uses prior art, is i.e. using During receive the power of paper due to pen core, along with the abrasion of the outside pen core of nib, the pen core within the shaft of a writing brush always can be outside It is mobile, until pen core is exhausted.The central canal shaft of a writing brush to be stretched out 15mm-20mm within penholder.During the radius of thimble is slightly smaller than The internal diameter of heart pipe, injects inside central canal in the case of need not change core, and thimble shell is hollow structure, and side is opened wide, top End seals, and thimble is fixing with housing top end to be connected, and when thimble injects central canal, shell can be enclosed within penholder top.When being not required to During core to be changed, thimble fully injects inside central canal, in preventing pen core from being slided into by the gap between storage core cavity and central canal Inside heart pipe, cap for brush position in time moving core is used to need not use spring design at nib.When pen core is finished, automatic lead Horizontal positioned, pulls back with handle, rocks propelling pencil the most gently, and pen core i.e. can drop to center from storage core cavity Pipe, then handle pushes away forward, and thimble is deeply into pipe, and shifts the pen core dropping to central canal onto pen tip position, the most just Can directly use.

Owing to have employed said structure, propelling pencil can quick change core soon needs change core when, it is not necessary to open pen Cap, take out pen core from Pencil lead box with hands, then be placed in a chamber, it is to avoid waste of time and hands are directly stained with on pen core Graphite, it is not necessary to wash one's hands frequently, has saved the time, it is ensured that the sanitation and hygiene of hands.

As improvement, the cross section of described storage core cavity is fan-shaped, and described storage core cavity connects with central canal, and communicating position has one The gap that bar is isometric with storage core cavity, the wide 2mm-3mm of seam, storage core cavity is designed as sector, on the one hand, in the situation that shaft of a writing brush thickness is certain Under, the capacity of storage core can be increased；On the other hand, it is also easier to drop to central canal from gap than core, and stitches a width of 2mm- The design of 3mm makes to have the when of changing core every time and only a pen core drops to central canal, places multiple pen core at central canal Blocking occurs at Bi Tou, damages propelling pencil.

Owing to have employed said structure, it is possible to achieve Large Copacity storage core, will not changing core and propelling pencil uses when Blocking occurs, damages.

As improvement, the top of described storage core cavity is provided with slip lid, and the end of described handle is spherical, described central canal and Penholder is transparent.When the pen core stored up in core cavity makes to be finished when, unload thimble and thimble shell, open slip lid, can be by new Pen core is placed in storage core cavity, covers slip lid.The end of handle is the spherical behaviour that is more convenient for changing core handle toward post-tensioning when Make, changing core and propelling pencil normally uses when, it is possible to observed the use of pen core by transparent penholder and central canal Situation and whether have pen core to drop in central canal.

Owing to have employed said structure, propelling pencil pen core when in use can be avoided to skid off from storage core cavity, and Changing core when, whether immediate observation is to having pen core to drop to central canal from storage core cavity, it is possible to reach conveniently to change core in time.

In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:

1, storage core capacity is big, it is possible to reach to need not for a long time add pen core to the storage core cavity of propelling pencil；

2, fast quick change core, changing core when, hands will not touch pen core, will not be stained with the graphite on pen core, it is ensured that hands Hygiene and health；

3, i.e., the service condition of observable pen core, convenient changes core in time.
