It also includes a container restraint ring 8 built in the positioning bin 4. The container restraint ring 8 includes a switchable tightened state and relaxed state. The tightened container restraint ring 8 surrounds and restrains the sample container 3 in the corresponding positioning bin 4. The present invention realizes the pressing positioning of the sample container 3 by lifting and opening / closing the lid and the surrounding restraint positioning. Among them, the pressing positioning is realized by the cooperation of the box cover 2 and the sample turning box 1, and the surrounding restraint positioning is realized by the container restraint ring 8 in the tightened state, thereby improving the stability of the sample container 3 positioned in the positioning bin 4 and avoiding the sample container 3 from being opened or broken due to loose positioning and collision, resulting in the sample being scattered.

The container restraint ring 8 is an airbag structure ring. This airbag structure ring switches between the tightened state and the relaxed state by inflating and deflating. The airbag positioning method that can be inflated and deflated can not only arbitrarily adjust the force of surrounding and restraining the sample container, but also adjust the size, which is suitable for sample containers with different diameter sizes, and improves the positioning application range. More specifically, as shown in the attached Figure 3 figure, the container restraint ring 8 that is an airbag structure ring is composed of an outer ring skeleton part 81 and an inner ring bladder part 82. The outer ring skeleton part 81 is connected to the bin rack 6. The inner ring bladder part 82 is circumferentially laid along the inner circumferential surface of the outer ring skeleton part 81 to form a complete airbag structure ring. The setting of the outer ring skeleton part 81 is to enable the inner ring bladder part 82 to have a larger structural extension range in the axial direction and improve the surrounding restraint positioning stability.
