寒假里我研究出了一种鲁班锁,它叫“圆宝石立方体”。它上面是圆形的,整体是圆柱体。它拼起来很牢固,不易松动。第一次拿到的时候我转了半天不知道从哪块下手,左瞧瞧右瞅瞅,左按按右晃晃,我拿拿这一块,拿拿那一块,终于找到了拆开它的第一个零件。虽然好不容易拆开了,但是,我却不知道怎么把它安起来。回到家后,我开始研究它,我试了无数遍都没有成功。这个跟我以前安过的鲁班锁 Winter vacation I developed a Luban lock, it is called “round gem cube ”. It is circular above, the overall cylinder. It is very solid together, not easy to loose.
