Male joint holding part of automatic chemical agent supply device

The present invention relates to a male joint holding part of an automatic chemical agent supply device, in which an upper platform capable of independently moving in the front-back direction is arranged on a lower platform which moves in the front-back direction by a conveying unit, so that when a male joint with an elongated neck region is mounted on the holding part, the upper platform can be independently moved in the front-back direction; and the automatic chemical agent supply device also can be smoothly and normally driven. 本发明涉及化学制剂自动供应装置的公接头保持部，在通过运送单元向前后方向移动的下部平台上配置可独立地向前后方向移动的上部平台，据此在颈部区域被拉长的公接头安装在保持部的情况下，化学制剂自动供应装置也可顺利的正常驱动。
