[0027] In the present embodiment, the poking part 122 is provided with a rounded corner structure 1221, which helps to more smoothly and stably poke the sample rack 22.

[0028] In the present embodiment, the bearing mechanism 2 comprises a bearing rack 21 and a sample rack 22, the bearing rack 21 is provided with a strip-shaped hole 211 corresponding to the poking block 12, allowing the poking block 12 to extend and poke the sample rack 22 in the rotating process. In the present embodiment, the sample rack 22 is connected with the bearing rack 21 through a sliding rail and a roller, so as to move in a specific direction under the poking of the poking block 12.

[0030] In the embodiment, when the driving motor starts, the driving motor transmits power to the push block 12, so that the push block 12 starts to rotate. During the rotation, the pushing part 122 of the push block 12 extends out of the strip-shaped hole 211 on the bearing frame 21 and contacts the sample frame 22.
