The bottom of the placement rack 2 is connected to a sliding support frame 303, and the bottom of the sliding support frame 303 abuts against the protective shell 1. The interior of the protective shell 1 is connected to an anti-falling baffle 304, and the anti-falling baffle 304 and the placement rack 2 are both arranged in a stepped shape. A take-in and take-out port 305 is provided on one side of the protective shell 1, and the placement rack 2 and the anti-falling baffle 304 are both provided with slots near the take-in and take-out port 305. A storage area 4 is provided on the upper side of the anti-falling baffle 304, and a cover plate 401 is provided on the upper side of the storage area 4, and the cover plate 401 is plugged into the top slot of the protective shell 1.

[0029] In specific implementation, in order to prevent the sample test tube from bouncing and falling off from the sample storage rack when it is hit, the placement rack 2 is arranged in a stepped shape, and a corresponding stepped anti-falling baffle 304 is arranged on the upper side of the placement rack 2, which can vertically limit the position of the sample test tube to prevent it from jumping off. When taking the sample test tube, it is only necessary to rotate the placement rack 2 at the access opening 305 through the sliding connection groove 301 and the sliding support frame 303, and rotate the required sample test tube on the upper side of the placement rack 2 to the access opening 305 to take it out, completing the sample test tube.
