夹钣

                                        固名思义

                             你的作用就是“夹”

                             借接头螺栓之力

                             把两根钢轨接头夹住

                             为的是

                             使两根钢轨连接一整体

                             共同承受

                             来自列车长龙的千钧之力

                             你也一样

                             与两根钢轨并肩承受

                             何惧拦腰折断

                             不惜牺牲自己

                             不管春夏秋冬

                             无论严寒酷暑

                             默默无语

                             奉献人类
