    摘要: A lead cartridge for a mechanical pencil, provided with an openable capping structure. The openable capping structure is fixedly joined to the open end, namely, the front end, of the lead cartridge so as to engage the lead guide of the mechanical pencil when the lead cartridge is inserted in the mechanical pencil. The openable capping structure opens a lead passage formed therein when engaged with the lead guide and closes the lead passage when separated from the lead guide to prevent the leads contained in the lead cartridge falling off the lead cartridge.

    摘要翻译: 一种用于自动铅笔的铅盒,带有可打开的封盖结构。 可开启的封盖结构固定地连接到引线盒的开口端,即前端,以便当铅盒插入机械铅笔时,与导线引导件接合。 当与引导引导件分离时,可打开的封盖结构打开形成在其中的引导通道,当引线引导件分离时封闭引线通道,以防止引线盒中包含的引线从引线盒中脱落。
