Abstract

A continuous erasable pen belongs to the technical field of writing devices combined with other supplies according to the International Patent Classification (IPC). The utility model is to solve the technical problem that when grasping the pen and writing incorrect characters, the user can immediately erase the wrong characters only by moving the forefinger without changing the angle and the direction of the pen and moving the thumb and the middle finger which are grasping the pen, and write the correct characters where the incorrect characters are erased, so that the writing and the correction can be conducted continuously as the strokes of the characters written, so as to save every second of precious time for every examinee. The continuous erasable pen consists of a pen head shell, a pen tail shell, an erasable pen, a liquid writing pen, a slider, a spring and a pen cap. The erasable pen and the liquid writing pen are arranged on the same end of the pen head shell; the erasable pen tip can automatically recess into the pen head shell after erasing the incorrect characters. The continuous erasable pen has simple structure; after the pen cap is covered, the shape and the fineness of the pen are the same with the original pen.

Description

Continuous erasable pen

Technical field:

Continuous erasable pen is divided by international monopoly (IPC), belongs to the writing implement technical field with other articles for use combination.

Technical background: known erasable pen mostly has two, writes for one, and a wiping, or nib can be write in one-pen, falls a tail and can wipe, and uses all inconvenient.

Summary of the invention:

This novel purpose provides a kind of continuous erasable pen, it when normally writing, find wrongly written character, without the angle and direction of conversion pen, the mother that holds a pen refer to need not to move with middle finger, as long as light moving forefinger, can reach the technical problem that moment is wiped wrongly written character, correct word is write in the place that is to wipe wrongly written character again, making writes can carry out as the stroke that writes continuously with correcting mistakes.

The purpose of this utility model is achieved in that continuous erasable is made up of written shell, a tail shell, magic stump, fluidity lettering pen, slide block, spring, the cap for brush.The evil spirit stump is for wiping the wiping word pen of the writing that the fluidity lettering pen writes, the fluidity lettering pen is for writing the writing pen of liquid writing in the place that magic stump is wiped writing again, the design of nib shell inwall has the parallel muscle portion of twice, its muscle portion is being divided into magic stump chamber and fluidity lettering pen chamber in the written shell, fluidity lettering pen chamber tapping property writing appliances, evil spirit stump chamber is put magic stump, evil spirit stump and fluidity lettering pen are positioned at the same end of written shell, the side design that the nib shell is adorned magic stump has the recess slideway, slide block and recess slideway are slidingly matched, side protuberance on slider bottom groove and the magic stump body closely is fastened and connected, the anterior design of nib shell has two apertures, one aperture communicates with magic stump chamber, and magic stump nib portion with aperture movingly; Another aperture communicates with fluidity lettering pen chamber, fluidity lettering pen nib stretches out in front position outside the written shell from the aperture of fluidity lettering pen chamber, the screw thread of nib shell afterbody is connected with the threaded engagement on the tail shell, spring between magic stump protuberance and magic stump chamber aperture inner edge wall, and with magic stump front portion movingly.

Normally write when finding wrongly written character, the downward flicking slide block of forefinger, slide block drives magic stump and moves downward, and against the force of the spring makes magic stump nib stretch out from magic stump chamber aperture simultaneously, and above fluidity lettering pen nib, after having wiped wrongly written character, unclamp forefinger, magic stump and slide block are owing to the elastic force effect of spring resets, magic stump nib is withdrawn in the magic stump chamber, covers its shape thickness of the cap for brush and conventional pen and be as good as.

Owing to adopt such scheme, design has twice muscle portion in the nib shell, magic stump can directly be contacted in written shell with the fluidity lettering pen, make the handwriting thickness the same with original pen, this is novel to make to write and carries out as the stroke that writes is continuous with correcting mistakes, and strive can take an examination for each examinee the time the every minute and second quality time.

Description of drawings:

Fig. 1 is the broken section structural map of continuous erasable pen, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is cap for brush figure.

Among the figure: magic stump 4 fluidity lettering pens 5 slide blocks 6 springs 7 caps for brush of 2 tail shells of 1 written shell 38 muscle portions.

The specific embodiment

(below in conjunction with accompanying drawing to this novel further specifying):

Continuous erasable pen is made up of 1 tail shell of written shell, 2 magic stump 3 fluidity lettering pens 4 slide blocks 5 springs 6 caps for brush 7 among the figure.Evil spirit stump 3 can be wiped the writing that fluidity lettering pen 4 is write, fluidity lettering pen 4 can be write word again in the place that magic stump 3 is wiped writing, the design of nib shell 1 inwall has the parallel muscle portion 8 of twice, its muscle portion 8 is being divided into magic stump chamber and fluidity lettering pen chamber in the written shell 1, fluidity lettering pen chamber tapping property writing appliances 4, evil spirit stump chamber is put magic stump 3, evil spirit stump 3 and fluidity lettering pen 4 are positioned at the same end of written shell 1, the side design that nib shell 1 is adorned magic stump 3 has the recess slideway, slide block 5 is slidingly matched with the recess slideway, side protuberance on slide block 5 bottom grooves and magic stump 3 bodies closely is fastened and connected, the 1 anterior design of nib shell has two apertures, one aperture communicates with magic stump chamber, and magic stump 3 tips with aperture movingly; Another aperture communicates with fluidity lettering pen chamber, fluidity lettering pen 4 nibs stretch out in front position outside the written shell (1) from the aperture of fluidity lettering pen chamber, the screw thread of nib shell 1 afterbody is connected with the threaded engagement on the tail shell 2, spring 6 between magic stump 3 protuberances and magic stump chamber aperture, and with magic stump 3 front portions movingly.

Normally write when finding wrongly written character, the downward flicking slide block 5 of forefinger, slide block 5 drives magic stump 3 and moves downward, and overcomes spring 6 resistances simultaneously, magic stump 3 nibs are stretched out from magic stump chamber aperture, and surpass fluidity lettering pen 4 nibs, wiped wrongly written character after, unclamp forefinger, evil spirit stump 3 and slide block 5 are owing to the elastic force effect of spring 6 resets, magic stump 3 nibs are withdrawn in the magic stump chamber, cover the cap for brush 7, its shape and thickness and conventional pen are as good as.
