Description
Technical field
Exempt to cut the present invention relates to pencil technical field more particularly to one kind and exempt from by writing continuous pencil.
Background technique
Pencil be it is a kind of be used to write and dedicated class of drawing sketch, away from modern existing more than 400 years history.Wherein,
The pencil of drawing sketch is divided into all polymorphic types.Pencil is a kind of hand-held pen, tool for writing, painting on paper, it is
With graphite be pen core and rod is surrounding layer and is made, and the tail end of pencil can also have an erasing rubber, pencil and its
His pen is the difference is that its person's handwriting is easy to be rubbed off.The pencil of black is " wood is black ", and crayon is " the wooden color ".
Modern pencil is manufactured with " graphite " and clay, and graphite adds more, and pen core is softer, color is more black;And clay adds more
More, pen core is then harder, and color is more shallow.Pencil is still called pencil now, is the pen because of earliest extremely shapeless or similar pencil
For manufactured by " lead " metal, then then again because ancient times the Dark Ages is when chemical developer only just imparts rudimentary knowledge to beginners, people miss graphite
It is thought as one kind of lead, therefore " pencil " word is handed down in all multilingual and east-asian language, is widely used and do not correct.
Existing pencil just can be used after cutting system processing, and pencil-lead frangibility.
