Description

A kind of fluid erasable pen

Technical field

The utility model relates to a kind of writing implement, relates to a kind of fluid erasable pen specifically.

Background technology

Currently marketed pencil, kind and pattern are all a lot, traditional pencil pattern is a wooden shell interpolation carbon rod, refill an erasing rubber at afterbody then, need be when this pencil uses with pocket knife or the instrument that sharpens a pencil specially carbon rod is cut out from wooden shell, and then carbon rod fined away just can write, the drawback of this pencil is more, one needs to use pencil-knife or other aids in being to use, use trouble, two wearing and tearing of carbon rod when being to use need often sharpen a pencil, and relatively lose time, the 3rd, when sharpening a pencil, need higher skill, cause the carbon rod fracture easily, the 4th, the pencil nib lacks protective device, is not having to be easy to cause the nib fracture under the operating position, the 5th, with to the end the time since pencil too short can't continue to use have to abandon, the 6th, its shell can not use repeatedly, and the wasting of resources is more, and the 7th, environment there is certain pollution; Current also have a kind of propelling pencil, adopt more tiny carbon rod, be contained in the pen container, the folding of the flexible and nib mouth by pen container front end nib little by little is drawn out carbon rod internally, and mode is very ingenious, but owing to still adopt the form of carbon rod, if the firmly improper a little fracture that just is easy to cause carbon rod is cumbersome in writing process, and because its structure is relatively complicated, required precision height when pencil is made, manufacture difficulty is bigger; In addition also has a kind of pencil, what adopt is earlier carbon rod one to be cut successively, be fixedly mounted on one little tube, then several little seat tubes filled in the tubulose pen container, eject little from the pen container rear portion during use, make the carbon rod on the seat tube expose pen container, eject another tube again after carbon rod on one little uses, though this pencil has saved the trouble that sharpens a pencil, its accessory structure is many, the wasting of resources is also many, so do not popularize in actual now use.The disclosed pencil of China's ZL200320100077.3 patent " the soft core extensible pencil of air pressure " though removed the trouble that sharpens a pencil from, needs Compressed Gas to provide power just can write, so no matter making or all comparing difficulty aspect the maintaining.China's ZL03280484.9 patent " Multi-cored pencil " disclosed pencil has been removed the trouble that sharpens a pencil too from, has also saved timber, but must prior prefabricated pen core, and the waste of carbon rod in use is very big.

Summary of the invention
