The flip cover 3 plays a sealing and dust-proof role for the test tube to be placed inside the positioning seat 2. A limiting groove 8 is provided on the test tube support seat 14, and the bottom of the test tube 20 is located in the limiting groove 48. Test tube positioning cylinders 19 are provided on the two opposite sides of the test tube support seat 14, and the test tube 20 can be inserted into the test tube support seat 14 and ensure the aesthetics. The positioning cylinder 19 is a concave wheel structure, which is made of elastic material to protect the test tube 20 and ensure that the test tube 20 is tightened, and the test tube positioning cylinder 19 is engaged with the test tube 20. The bottom of the test tube support seat 14 is connected to the limit rod 12, and the side of the limit rod 12 is provided with a movable rod 6. The two ends of the test tube positioning cylinder 19 are connected to the first connecting rod 18 through the light rod rotation, and the other end of the first connecting rod 18 is connected to the second connecting rod 17 and the third connecting rod 15 through the light rod rotation. The other end of the third connecting rod 15 is connected to the test tube support seat 14 with a light rod structure, and the other end of the second connecting rod 17 is penetrated by the positioning rod 16, and the two ends of the positioning rod 16 are fastened in the positioning seat 2. After the test tube support seat 14 is subjected to the gravity of the test tube 20, this structure 14 can be moved downward, and the third connecting rod 15 is driven to move by the test tube support seat 14, so that the second connecting rod 17 cooperates with the third connecting rod 15 to move under the positioning of the positioning rod 7, and the first connecting rod 18 cooperates with the second connecting rod 17 and the third connecting rod 15 to move, so as to realize the gathering of the test tube positioning cylinder 19, so that the test tube positioning cylinder 19 clamps the test tube 20. Since the test tube positioning cylinder 19 is rotatable, the test tube 20 can be directly pulled out by pulling it upward. A connecting shaft 13 is respectively passed through between the movable rod 6 and the limiting rod 12. A spring 11 is provided under the limiting rod 12, and the upper and lower ends of the spring 11 are respectively welded and fixed with a spring seat 10, and the spring seat 10 is respectively fastened to the limiting rod 12 and the bottom of the inner wall of the positioning seat 2.
