[0022] In the initial state, the movable plate 6 is away from the reaction disk 2. When in use, the staff will place the test tubes containing body fluids in the multiple placement holes 3 one by one. After the measurement is completed, the driving member drives the slide bar 5 to slide upward, driving the movable plate 6 and the multiple lifting rods 7 to move upward together. The multiple lifting rods 7 push the multiple test tubes upward respectively, so that the test tube openings are away from the reaction disk 2, so that the subsequent staff can remove the test tubes from the reaction disk 2, which is convenient for operation and improves the measurement efficiency. After all the test tubes are removed, the driving member drives the slide bar 5 to slide downward, driving the movable plate 6 and the multiple lifting rods 7 to move downward to the initial position together;

[0023] To sum up, when the present application is in use, the driving member drives the slide rod 5 to slide upward, driving the movable plate 6 and multiple lifting rods 7 to move upward together. The multiple lifting rods 7 push the multiple test tubes upward respectively, so that the test tube openings are away from the reaction disk 2, so that the subsequent staff can remove the test tubes from the reaction disk 2. This facilitates operation and improves measurement efficiency, and is therefore more practical.

[0024] like Figure 2-Figure 3 As shown, in some embodiments, the driving member includes a ring plate 8 rotatably arranged on the instrument body 1, the ring plate 8 is in a horizontal direction, and a first plane 9, a first inclined plane 10 and a second plane 11 are constructed on the ring plate 8. The first plane 9 and the second plane 11 are both in a horizontal direction and have a height difference. A fixed block 12 is arranged on the slide bar 5, and the fixed block 12 is fixed at the bottom end of the slide bar 5. A roller 13 is rotatably arranged on the fixed block 12, and the roller 13 is in a vertical direction. The roller 13 rolls and overlaps with the first plane 9, the first inclined plane 10 and the second plane 11;

[0025] Referring to the above, in the initial state, the roller 13 rolls and overlaps with the first plane 9, and the movable plate 6 is away from the reaction disk 2. When in use, the ring plate 8 is driven to rotate forward, and the roller 13 first rolls from the first plane 9 to the first inclined plane 10, and then rolls from the first inclined plane 10 to the second plane 11. During this process, the roller 13, the fixed block 12 and the slide bar 5 move upward together. Conversely, the ring plate 8 is driven to reverse, and the roller 13, the fixed block 12 and the slide bar 5 move downward together due to gravity. The roller 13 first rolls from the second plane 11 to the first inclined plane 10, and then rolls from the first inclined plane 10 to the first plane 9.

[0026] like Figure 3 As shown, in some embodiments, a return spring 14 sleeved on the slide bar 5 is provided between the fixed block 12 and the fixed plate 4, and the return spring 14 is in a vertical direction and its two ends are respectively fixedly connected to the fixed block 12 and the fixed plate 4;

[0027] Referring to the above, in the initial state, the return spring 14 is in a natural state. When the roller 13, the fixed block 12 and the slide rod 5 move upward together, the return spring 14 is forced to be squeezed. When the ring plate 8 reverses, the return spring 14 will be squeezed and reset to the natural state. The roller 13, the fixed block 12 and the slide rod 5 move downward together due to elastic potential energy and gravity. The return spring 14 can avoid interference between the roller 13, the fixed block 12 and the slide rod 5 during movement.

[0030] like Figure 5 As shown, in some embodiments, a groove 18 corresponding to the shape of the bottom of the test tube is configured on the lifting rod 7, and the groove 18 is located at the top of the lifting rod 7;

[0031] Referring to the above, when the lifting rod 7 moves upward, the bottom of the test tube will enter the groove 18. Through the design of the groove 18, the test tube can be more stable when moving upward.

[0032] like Figure 2-Figure 5 As shown, in some embodiments, the ring plate 8 is constructed with a continuously distributed second inclined surface 19 and a third plane 20, the third plane 20 is in a horizontal direction and has a height difference with the second plane 11, the second inclined surface 19 is connected to the second plane 11, the diameter of the lifting rod 7 corresponds to the diameter of the placement hole 3, and the lifting rod 7 is detachably arranged on the movable plate 6. In this embodiment, the lifting rod 7 is composed of a plastic block and a rubber block distributed inside and outside, the plastic block is detachably connected to the movable plate 6, and the diameter of the rubber block is the same as the diameter of the placement hole 3;

[0033] Referring to the above, after the test tube is removed from the reaction disk 2, the ring plate 8 continues to rotate forward, and the roller 13 first rolls from the second plane 11 to the second inclined plane 19, and then rolls from the second inclined plane 19 to the third plane 20. During this process, the lifting rod 7 moves upward until it completely enters the placement hole 3, and the inner wall of the placement hole 3 is cleaned by the outer rubber block to avoid impurities on the inner wall of the placement hole 3 from contaminating the test tube during long-term use. Thereafter, the ring plate 8 is reversed, and the roller 13 first rolls from the third plane 20 to the second inclined plane 19, and then rolls from the second inclined plane 19 to the second plane 11. During this process, the lifting rod 7 moves downward until it completely exits the placement hole 3. The lifting rod 7 can be removed from the movable plate 6 and replaced with a new lifting rod 7 to keep the lifting rod 7 in a clean state.

[0034] like Figure 5 As shown, in some embodiments, the lifting rod 7 is configured with an inwardly contracted guiding slope 21, and the guiding slope 21 is located on the outer rubber block;

[0035] Referring to the above, when the lifting rod 7 enters the placement hole 3, the lifting rod 7 is guided by the guiding inclined surface 21, so that the lifting rod 7 can enter the placement hole 3 more smoothly and avoid movement interference.
