SHARP PENCIL ATTACHED TO SHARP PENCIL LEADS CASE

摘要

The present invention relates to a mechanical pencil to which a sharp lead case storing sharp leads therein is coupled. The mechanism pencil includes a body provided in the mechanical pencil, and a supply part supplying the sharp lead to the body by pressing operation of a button exposed outwardly from the mechanical pencil and working with the body. The supply part has a coupling portion connected to an engaging portion of the sharp lead case to communicate with each other, a connecting pipe communicating with the body and penetrating the coupling portion, a clamp having at least two cutout portions formed at one end of the connecting pipe, in which when the cutout portions are moved by a button, and then are exposed outwardly from the coupling portion, the cutout portions are widened in a combination state to open the connecting pipe and thus supply the sharp lead to the body, and a spring installed at a lower portion of the coupling to resiliently receive the clamp when the pressing operation of the button is released.
