[0030] The circumferential limiting of the sliding block structure is matched with the supporting and limiting of the bottom limiting structure, the sample container placed therein is basically positioned, and further fixed by the supporting and clamping mechanism arranged on the inner side, so that the sample container is stable during movement, and the water sample is prevented from spilling, tilting and the like.

[0031] The stabilizing and clamping mechanism 54 comprises a plurality of clamping units 541, each clamping unit 541 comprises a hinged seat 521 fixedly connected to the support structure 52, a clamping structure 542 is swingably arranged on the hinged seat 521 by a first elastic mechanism, and the bottom ends of a plurality of clamping structures 542 are gathered and arranged close to each other, wherein the first elastic mechanism adopts a torsion spring.

[0032] The torsion spring enables the clamping structures to be arranged in a relative inclined manner, and the bottom ends are gathered to form a bucket-shaped structure. When the sample container is inserted into the rack from top to bottom, the bottom of the container pushes apart the gathered ends of the clamping structures, and the deformation restoring force of the torsion spring finally enables the clamping structures to be clamped and fitted to the outer wall surface of the sample container, thereby achieving the effect of stabilizing and fixing the sample container.
