A Water Fitting Housing

Abstract The present invention provides a packaging box, including a box body; the box body is provided with an insertable zone; a dashed hole is disposed at an edge of the insertable zone. The insertable zone is round and may be completely or partially separated from the box body; there is an insertable zone on the box body. The packaging box provided by the present invention has an insertable zone. The detecting personnel need not find out an extra tubular fixed seat for use. Meanwhile, a packaging box is used to replace a tubular fixed seat, reducing the use cost of the detecting apparatus. Moreover, each lysis tube can be inserted into respective packaging box; and each packaging box is corresponding to respective detecting apparatus. Therefore, it is not easy to cause the misuse of lysis tubes during loading and detection procedure, thereby avoiding wrong detection because the lysis tube is taken by mistake. Fig.1 Fig.2
