Description
Technical field
The utility model relates to the writing appliance technical field, and be used to wipe word of being wrongly write by pencil or the propelling pencil of drawing the erasing rubber of wrong lines especially a kind of having.
Background technology
In the past, its structure of propelling pencil that people use all just comprises penholder and nib, and the active button that is contained in the penholder afterbody, and its afterbody mostly is with erasing rubber unlike Wood-bar pencil, people occur getting in wrong in writing process and look for erasing rubber in addition, inconvenience very.People had been stained with erasing rubber by adhesive on the afterbody button of propelling pencil afterwards, but such erasing rubber all is directly exposed to the outside, is stained with dust easily, and were dirty, and can not more renew again after using up, do not reach expected effect yet.
Summary of the invention
The purpose of this utility model is to provide a kind of propelling pencil that has movable erasing rubber, and it can solve sticking easily dust of erasing rubber on the existing propelling pencil and the problem that can not change.
In order to achieve the above object, the technical scheme that the utility model adopted is: establish the penholder of core storage tube and the nib that is connected with penholder by screw thread in it comprises, described penholder front end is provided with the lead for retractable pencil chuck, in the described core storage tube lead for retractable pencil is housed, described penholder tail end is provided with erasing rubber, this erasing rubber is with movable sleeve outward, and this movable sleeve is connected with penholder by screw thread.
Above-mentioned penholder can be provided with a pair of pulley side by side near described lead for retractable pencil chuck place, described pulley is embedded in the described penholder wall, the lateral separation of the lead for retractable pencil slideway that forms between this two pulley can be smaller or equal to the diameter distance of the cross section of lead for retractable pencil, the lead for retractable pencil passage that is communicated with above-mentioned core storage tube and described lead for retractable pencil slideway can be funnel-form, the passway that the passway that this lead for retractable pencil passage is connected with described core storage tube is connected with described lead for retractable pencil slideway greater than this lead for retractable pencil passage, to avoid like this causing several lead for retractable pencils to get lodged in the lead for retractable pencil passway, be difficult to arrive down the consequence of lead for retractable pencil passage.
Owing to adopted technique scheme, the utility model compared with prior art, the beneficial effect that has is as follows:
1, because movable sleeve is enclosed within outside the erasing rubber, and ability rotary moveable cover exposes erasing rubber during use, erasing rubber is just ensconced in the movable sleeve like this, avoids being stained with booties such as dust, and erasing rubber is kept clean.
2, because erasing rubber is that directly plug is to lean on friction between the two to fix, therefore, after former erasing rubber uses up, can be reentered into the new erasing rubber of same size again in movable sleeve, very convenient and practical.
