A nut 6 is threadedly connected to the screw rod 5. The side surface of the nut 6 is rotatably connected to the inner side surface of the rotating ring 7. A cross-shaped pressing plate 8 is fixedly installed on the side surface of the rotating ring 7. The pressing plate 8 cooperates with six test tube holders 42. By the cooperation of the screw rod 5 and the nut 6, the pressing plate 8 can be fixed on the rotating disk 31, so that the pressing plate 8 can press the test tube or sample tube tightly in the test tube slot 41 to prevent the test tube or sample tube from being thrown out during centrifugation. A handwheel 9 is fixedly installed on the top of the nut 6. A through hole matching the screw rod 5 is opened in the middle of the top of the handwheel 9. Through the handwheel 9, people can conveniently twist the nut 6 to facilitate the fixation of the pressing plate. The motor 33 is electrically connected to the control module 2. By driving the rotating disk 31 to rotate through the motor 33, the rotating disk 31 drives the test tube holder 42 and the test tube or sample tube in the test tube holder 42 to rotate at a high speed,
[0019] so as to separate the serum from the coagulated blood;
[0020] The test tube holder replacement mechanism 4 includes a test tube slot 41, a test tube holder 42, a clamping plate 43, a clamping block 44, a spring 45, a mounting groove 46 and a guide rod 47. The mounting groove 46 is opened at the top of the rotating disk 31. The test tube holder 42 is movably installed in the mounting groove 46. Two test tube slots 41 are opened at the top of the test tube holder 42. Two handle slots 12 are opened on the side surface of the upper end of the test tube holder 42. Grooves matching the handle slots 12 are opened at the top of the rotating disk 31. Through the handle slots 12, people can conveniently lift the test tube holder 42 for disassembly and replacement. Guide rods 47 are slidably installed in two slide holes on one end side wall of the mounting groove 46. One ends of the outer sides of the two guide rods 47 are fixedly connected to the side surface of the L-shaped clamping plate 43. A push plate 10 is fixedly installed at the top of the clamping plate 43. A positioning groove 11 matching the push plate 10 is opened at the bottom of the pressing plate 8. When replacing the test tube holder 42, the push plate 10 can conveniently push the clamping plate 43 to move, facilitating the removal and insertion of the test tube holder 42.

When centrifugally separating blood samples in test tubes or sample tubes of different specifications, the test tube holder 42 suitable for the specifications of the test tube or sample tube can be placed into the mounting groove 46. When placing, push the clamping plate 43 to move, so that the clamping plate 43 compresses the spring 45. Place the test tube holder 42 into the mounting groove, and the elastic force of the spring 45 pushes the clamping plate 43 to move, so that the clamping plate 43 fits with the test tube holder 42, and cooperates with the clamping block 44 to clamp the test tube holder 42 in the mounting groove 46. Thus, a separation device can meet the separation of blood samples in different test tubes or sample tubes, reducing the complexity and cost during serum separation and facilitating use.
[0021] Working principle of the present utility model: Connect the external power supply, symmetrically insert the test tube or sample tube containing the blood sample into the test tube slot 41 on the test tube holder 42, sleeved the nut 6 on the screw rod 5, and turn the hand wheel 9, so that the hand wheel 9 drives the nut 6 to rotate, making the nut 6 move downward along the thread direction on the screw rod 5, causing the nut 6 to drive the pressure plate 8 to move downward, and making the rubber pad 13 on the pressure plate 8 press the test tube or sample tube tightly in the test tube slot 41. When the pressure plate 8 moves downward, the push plate 10 will insert into the positioning slot 11 on the pressure plate 8 to provide positioning for the pressure plate 8. Control the motor 33 to work through the control module 2, so that the output shaft of the motor 33 drives the rotating disk 31 to rotate, making the rotating disk 31 drive the test tube holder 42 and the test tube or sample tube in the test tube holder 42 to rotate at high speed, causing the blood in the test tube or sample tube to be layered. After centrifugation, collect the supernatant liquid on the upper layer in the test tube or sample tube, and then serum can be obtained. When separating the blood samples in test tubes or sample tubes of different specifications, the push plate 10 can be pushed, so that the push plate 10 drives the clamping plate 43 to move along the direction of the guide rod 47, making the clamping plate 43 compress the spring 45. At this time, the clamping plate 43 will be separated from the test tube holder 42. Hold the test tube holder 42 through the handle groove 12, push the test tube holder 42 in the direction of the clamping plate 43, making the test tube holder 42 separated from the clamping block 44, and lift the test tube holder 42 upward to remove the test tube holder 42. Lift the test tube holder 42 with the same test tube slots 41 as the test tube or sample tube to be separated, and push the push plate 10, then put the test tube holder 42 into the installation slot 46. Release the push plate 10, and the elasticity of the spring 45 will push the clamping plate 43 in the direction of the test tube holder 42, making the clamping plate 43 push the test tube holder 42 to move towards the other end of the installation slot 46, so that the stepped surface on the test tube holder 42 is in full contact with the clamping plate 43 and the clamping block 44. At this time, insert the test tube or sample tube into the test tube slot 41, and repeat the above serum separation operation to separate the serum in test tubes or sample tubes of different specifications.
[0022] It should be noted that when replacing the test tube holder 42, the operating specifications of the centrifugation equipment should be followed, and at the same time, replace two symmetric test tube holders 42.
