Description

A kind of novel environment friendly pen

Technical field

The utility model relates to a kind of novel environment friendly pen.

Background technology

At present, when the employed pencil of middle school student all is wooden, be unfavorable for so very much environmental protection at real life, cause the wasting of resources, and China's afforestation rate be low, the forest reserves are very valuable.The someone invents out propelling pencil for this reason, released double fastener hair style propelling pencil no residual propelling pencil series such as (seeing China Patent No. 96200727.7,96217642.7,01200736.6,96217642 etc.) as some research institutions of Japan (Co., Ltd.), they mainly are to have used the double collet structure in the pen instead, the fore-clamp head-clamp is held the front end of lead for retractable pencil, and back chuck is responsible for clamping and is advanced lead for retractable pencil.So can shorten residual core length effectively, can work as pencil with being as short as back chuck institute can not clamping the time, preceding chuck can't clamp lead for retractable pencil at all, causes long residual core can not continue to use, and causes waste.And, existing propelling pencil is constructed also more complicated, thereafter chuck mostly adopts the push structure of more complicated, the front and back chuck may cause the lead for retractable pencil fracture when rotated, and the equal more complicated of the making of front and back chuck, the propulsive mechanism of back chuck and the manufacturing cost of bunching ring and precision thereof are also higher, and these all have been some defectives that are difficult to overcome that propelling pencil exists since a century.
