拓竹 A1 系列托盘支架上的另一根杆子，与原来的杆子尺寸相同，不仅可以完美地拧入孔中，而且创新性地将塞子收纳进杆子的头部，不影响原有的功能和结构，让我们可以在支架上同时放置两个托盘的耗材，方便我们快速更换耗材。

The other pole on the Bamboo A1 Series tray holder, which is the same size as the original pole, not only screws perfectly into the hole, but also innovatively stows the stopper into the head of the pole without affecting the original function or structure, allowing us to place two trays of supplies on the holder at the same time, making it easy for us to change supplies quickly.
