The guide block 603 and the limit block 73 are both right triangles, and the guide block 603 and the limit block 73 are in opposite directions. Figure 5 As shown, this structure is used to move the movable plate 307 to the connecting groove 9 when taking the blood collection tube 4, and then move the movable plate 307 outward along the fifth slide groove 72 at the connecting plate 71. When the guide block 603 at the movable plate 307 contacts the limit block 73, the splints 504 on both sides of the blood collection tube 4 are moved toward the first movable groove 501 under the guidance of the limit block 73, thereby facilitating the removal of the blood collection tube 4.

[0035] Furthermore, a rotating assembly 8 is provided at the bottom of the turntable 301, and the rotating assembly 8 includes a third movable groove 801, a first rotating shaft 802, a ratchet 803, a second rotating shaft 804, a limiting plate 805, teeth 806, a telescopic rod 807 and a third spring 808. The bottom of the housing 1 is provided with a third movable groove 801, the bottom center of the turntable 301 is fixedly connected to the first rotating shaft 802, the outer side of the first rotating shaft 802 is fixedly connected to the ratchet 803, and the bottom of the housing 1 is provided with a third movable groove 801. The second rotating shaft 804 is rotatably connected, and the outer side of the second rotating shaft 804 is fixedly connected to a limit plate 805. The limit plate 805 is fixedly connected to the side facing the ratchet 803 with teeth 806. The inner wall of the third movable groove 801 is connected to a telescopic rod 807. A third spring 808 is provided in the telescopic rod 807. The two ends of the third spring 808 are respectively against the telescopic rod 807 and the inner wall of the third movable groove 801. The other end of the telescopic rod 807 is in contact with the surface of the second rotating shaft 804. Figure 6 As shown, this structure is used to drive the ratchet 803 to rotate through the first rotating shaft 802 when the turntable 301 rotates. When the ratchet 803 rotates, it pushes the teeth 806 at the limit plate 805, so that the limit plate 805 rotates under the action of the second rotating shaft 804, pushing the telescopic rod 807 and squeezing the third spring 808. Under the elastic action of the third spring 808, the telescopic rod 807 is pushed to insert the teeth 806 into the gap of the ratchet 803, limiting the ratchet 803, thereby fixing the turntable 301 to prevent the turntable 301 from rotating when taking or placing the blood collection tube 4.

[0036] Furthermore, six groups of observation windows 10 are fixedly mounted on the outer surface of the housing 1, and the observation windows 10 are made of transparent material. Figure 2 As shown, this structure is used to observe the status of the blood sampling tube 4 in the storage tank 304 through the observation window 10 outside the shell 1.

[0037] Working principle: When used, Figure 6 and Figure 7 As shown, the turntable 301 is rotated along the first sliding groove 303 through the first sliding block 302. During the rotation, the turntable 301 drives the ratchet 803 to rotate through the first rotating shaft 802, so that when the ratchet 803 rotates, it pushes the teeth 806 at the limit plate 805, so that the limit plate 805 rotates under the action of the second rotating shaft 804, pushing the telescopic rod 807 and squeezing the third spring 808. Under the elastic action of the third spring 808, the telescopic rod 807 is pushed to insert the teeth 806 into the gap of the ratchet 803, limiting the ratchet 803, thereby fixing the turntable 301, avoiding the turntable 301 from rotating when taking or placing the blood collection tube 4, and causing the corresponding blood collection tube 4 to rotate to the connecting groove 9. Figure 5 and Figure 7As shown, the movable plate 307 is moved outward along the second slide groove 305 through the second slider 306, so that the second slider 306 moves to the fifth slide groove 72 and continues to move outward, as shown in FIG. Figure 4 and Figure 5 As shown, when the guide block 603 at the movable plate 307 contacts the limit block 73, the clamping plates 504 on both sides of the blood sampling tube 4 are moved toward the first movable groove 501 under the guidance of the limit block 73, so that the blood sampling tube 4 can be taken out conveniently and the blood can be collected at the position indicated by the blood sampling tube 4. After the blood collection is completed, the blood sampling tube 4 is moved inward along the inner wall of the movable plate 307, thereby pushing the guide blocks 603 on both sides, so that the guide blocks 603 move inward along the second movable groove 601 through the second movable block 602, and the first The second spring 604 is squeezed to cause it to deform. When the blood sampling tube 4 moves to the inside of the movable plate 307 and is completely separated from the guide block 603, the second spring 604 rebounds to restore the guide block 603 to its original position and limit the front side of the blood sampling tube 4. Then, another group of blood sampling tubes 4 are taken out and placed in the same way. After the blood sampling is completed, the remaining group of storage slots 304 is moved to the connecting slot 9 to protect the blood sampling tube 4 inside. The above is the entire working principle of the present invention.
