Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0017] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See also Figures 1 to 3 As shown, a clinical blood sample rack involved in this embodiment includes an upper support plate 1 and a lower support plate 2, wherein the upper support plate 1 is provided with a plurality of sample jacks 3 arranged in a rectangular array, and an extension tube 4 with an upper tube opening connected thereto is provided below the sample jacks 3, and the extension tube 4 is provided on the upper support plate 1, and an annular groove 5 close to the lower tube opening is provided on the outer tube wall of the extension tube 4, and an elastic rubber ring 6 surrounding the extension tube 4 is embedded in the annular groove 5, and the elastic rubber ring 6 is a medical silicone ring, and a plurality of deformation grooves 7 extending along the axial direction are provided on the extension tube 4, and the deformation grooves 7 extend from bottom to top, and the notch of the deformation groove 7 is provided at the lower end of the extension tube 4, and the deformation groove 7 passes over the annular groove 5, and a spring piece 8 integrated with the extension tube 4 is formed between two adjacent deformation grooves 7.

[0020] In this embodiment, since the elastic rubber ring 6 providing the inner contraction force is embedded in the deformation groove 7, the spring pieces 8 formed between the two adjacent deformation grooves 7 converge inwardly and are appropriately retracted into the extension tube 4. When the blood sample tube is inserted along the sample insertion hole 3, the converged spring pieces 8 are pushed outwardly, and the reaction force of the spring pieces 8 clamps the blood sample tube to form a tight fitting connection relationship.
