[0012] As a further preferred solution, a handle is fixed to one side of the upper end surface of the upper plate, and the handle is provided with anti-slip grooves.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] 1. Thanks to the cooperation between the limiting cylinder and the inoculator, the utility model can quickly sample microorganisms through multiple inoculators on the lower end surface of the upper plate, and then quickly and evenly inoculate them into the limiting cylinder, which is simple to operate and easy to use.

[0015] 2.
