Abstract

The utility model discloses a lead-saving mechanical pencil, which belongs to writing or drawing supplies, comprises a pencil tube and a pencil core, and is characterized in that two semi-circular arc flat copper bars are mounted between the pencil tube and the pencil core, a lead fixing cylinder is arranged at the position of 0.3 centimeter to 0.5 centimeter of the lower end of each flat copper bar and identical with the lead in inner diameter, and the upper end of each flat copper bar is fixed at the top end of the pencil tube. The lead-saving mechanical pencil has the advantages that since the flat copper bars are additionally mounted between the pencil tube and the pencil core, when a small segment of lead in the pencil core is left, a user rotates the pencil tube and presses a button at the position of pencil holding, and then the residual small segment of lead can be clamped tightly by the lead fixing cylinder at the lower ends of the flat copper bars until the lead is used up, so that lead is saved and pollution of the residual lead to the environment is prevented.

Description

A kind of joint is plumbous from starting writing

Technical field

The utility model belongs to be write or drawing article, particularly uses starting writing certainly of lead for retractable pencil.

Background technology

Various to start writing is the most frequently used writing implements of people, general starts writing certainly, and when lead nearly uses up, remaining a bit of can't the use caused waste, and the lead that can't use also can pollute environment.

The utility model content

In order to overcome general lead can't being used up from starting writing is that remaining lead pollutes deficiency to environment, and it is plumbous from starting writing that the purpose of this utility model provides a kind of joint, uses the plumbous people that start writing certainly of this joint very convenient lead to be exhausted.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of joint is plumbous from starting writing, comprise the automatic shaft of a writing brush, pen core, it is characterized in that: at the flat copper that two semicircular arcs are housed between the shaft of a writing brush and the pen core automatically, flat copper lower end 0.3--0.5 centimeters is the internal diameter lead for retractable pencil stationary magazine creel identical with lead for retractable pencil, and the flat copper upper end is fixed on the top of the automatic shaft of a writing brush.

The place of holding a pen of the described automatic shaft of a writing brush is provided with movable plastic button.

The beneficial effects of the utility model are owing to installing flat copper additional between the shaft of a writing brush and the pen core automatically, when the lead in the pen core of starting writing certainly is also remaining a bit of, the rotational automatic shaft of a writing brush, press the button that the automatic shaft of a writing brush holds a pen and locates, make the lead for retractable pencil stationary magazine creel of the lower end of flat copper clamp remaining a bit of lead, until using up lead, promptly saved with lead and prevented the pollution of residual lead again environment.
