求翻译：每一主节点必须设置一根横向水平杆，并采用直角扣件扣紧在纵向水平杆上部，端头个处伸出长度不小于10cm，该杆轴线偏离主节点的距离不应大于15cm。双排架中靠墙一侧的外伸长度不应大于50cm。是什么意思？

Each master node must be set to a horizontal bar, right-angle fasteners and fastening in longitudinal horizontal rod section, end of the first one at the extended length of not less than 10cm, the rod axis deviation from the master node distance should not be more than 15cm . The double bay against

Each of the primary node must be set up a lateral horizontal bar, and a right-angle fastener clip in the longitudinal horizontal bar, upper end of the extended length is not less than 10 CM, the rod axis away from the main node of the distance should be no more than 15 cm . Dual side by side against

Each master node must establish a crosswise horizon bar, and uses the right angle to buckle to fasten tightly on the longitudinal horizon bar, the reason place swinging radius is not smaller than 10cm, this pole spool thread deviation master node distance should not be bigger than 15cm.In the double
