    • A building blocks type writing instrument having a plurality of writing units, each of which is provided with a pencil lead at its front end, and at least one coupling unit engaged insertedly axially with each other in series. The writing units is formed having the front end provided with a tubular projection for insertion of pencil lead and the rear end with an insertion hole for insertion and engagement of the tubular projection at the front end, and on the outer circumferential surface at least one engaging projection at least one coupling groove corresponding to the engaging projection for engagement side by side transversely of another writing unit by corresponding engaging groove and projection. The coupling unit has a tubular body with front end and the lower portion provided on the two back to back lateral sides each cross shape coupling unit for cross engagement of the writing units. As one with a tubular projection corresponding to that of the writing unit. On the rear end there is an insertion hole corresponding to that of the writing unit. Further on the two lateral sides where a tubular projection is absent are located with engaging projection and or coupling grooves corresponding to the those of the writing unit. The tubular body and the three tubular projections, in total, form a T-shaped coupling unit.
    • 一种积木式书写工具,具有多个书写单元,每个书写单元在其前端设置有铅笔引线,以及至少一个联结单元,它们彼此串联插入。 书写单元形成为具有前端,该前端设置有用于插入铅笔引线的管状突起,后端具有用于在前端插入和接合管状突起的插入孔,并且在外周表面上具有至少一个接合 突起与接合突起对应的至少一个连接槽,用于通过相应的接合槽和突起与另一个书写单元横向并排地接合。 联接单元具有管状体,其具有前端,并且下部设置在两个背对侧侧面,每个横向形状的联接单元用于书写单元的交叉接合。 作为与写入单元相对应的管状投影。 在后端有一个对应于书写单元的插孔。 此外,在不存在管状突出部的两个侧面上,具有与书写单元相对应的接合突起和/或耦合槽。 管状体和三个管状突起总共形成T形联接单元。
