When test tubes of different diameters are embedded in the adapter slots, the controller panel energizes the electromagnetic bottom ring, and the lower slotted limit vertical rod senses the downward pressure, and the lower slotted limit vertical rod below is compressed and downward, and the remaining vertical rods wrap the outer wall of the test tube, adaptively fixed, and prevent shaking and collision, thereby reducing the risk of test tube rupture and specimen leakage, reducing hemolysis, and improving the work efficiency of medical staff in batch transporting specimens of different specifications.

[0020] Secondly, in the present invention, the shock-absorbing bottom plate is in contact with the transport base surface to buffer the vibration force generated during transportation, which can protect the specimen to the greatest extent and reduce the risk of hemolysis.
