In this embodiment, the uranium hexafluoride sampling container is selected as a P10 uranium hexafluoride sampling container, which is an important equipment in the nuclear fuel system and is used for sampling, storage and transportation of uranium hexafluoride samples. In this embodiment, the lower buffer storage member 2 is provided with eight placement holes 21 adapted to the shape of the P10 uranium hexafluoride sampling container. The placement holes 21 are stepped holes that are larger at the top and smaller at the bottom. The upper diameter of the stepped holes is slightly smaller than the upper outer diameter of the P10 uranium hexafluoride sampling container. The staff inserts the P10 uranium hexafluoride sampling container into the placement holes 21 and utilizes the resilience of the EPDM rubber foam sponge to achieve stable fixation of the P10 uranium hexafluoride sampling container. When the staff needs to take it out, they only need to grab the top plug of the P10 uranium hexafluoride sampling container.
