[0033] Reference Figure 1-Figure 3The limiting mechanism includes a limiting block 14, which is fixedly connected to the outer wall of the left end of the guide rod 10. The surface of the limiting block 14 is clamped with an insert block 16, and the limiting block 14 matches the insert block 16.

The bottom end of the T-block 17 is connected to one end of the connecting spring 18, and the other end of the connecting spring 18 is fixedly connected to the driving frame 3. On the surface, the original state of the connecting spring 18 is a contracted state, so that the limit block 14 and the plug block 16 fit together under the elastic force of the connecting spring 18, the clamping plate 6 passes through and is slidably connected to the sides of the driving frame 3 and the moving frame 4, the guide rod 10 passes through and is slidably connected to the outer walls of the moving frame 4 and the driving frame 3 respectively, the three moving rods 5 are slidably connected to the inner walls of the driving frame 3 and the moving frame 4 respectively, the right end of the moving rod 5 is fixedly connected to one end of the reset spring 9, and the other ends of the three reset springs 9 are fixedly connected to the driving frame 3 and the inner wall of the right end of the moving frame 4 respectively.

When resetting, the elastic force of the reset spring 9 is used to move the moving rod 5 to the right.

[0034] Working principle: After the test tube is inserted into the inside of the reagent carrier plate 2, the T-block 17 is first moved upward to separate the insert block 16 from the limit block 14, and then the guide rod 10 is moved to the left to drive the moving rod 5 to move, so that the side of the moving rod 5 moves with the clamping plate 6 to the right side of the test tube, and then the clamping plate 6 limits and fixes the right side of the test tube, and then the T-block 17 is released. Under the elastic force of the connecting spring 18, the insert block 16 is plugged into the limit block 14, so that the clamping plate 6 can limit and fix the right side of multiple test tubes. When the test tube is of different sizes, the disc 8 is moved to the left by rotating the fastening bolt 13. For example, when the test tubes are of different diameters, the disc 8 moves to the left side of the test tube, so that the disc 8 fits the left side of the test tube. If the disc 8 has been in contact with the surface of the test tube, rotating the fastening bolt 13 will drive the disc 8 to continue to fit the test tube. The rubber disc 8 contacts the surface of the test tube, and the friction generated will cause the rubber disc 8 to deform, thereby meeting the limit fit for test tubes of different sizes, thereby increasing the utilization rate of the detection reagent oscillation mixing device.

[0035] When the cover plate 12 is capping the test tube, the L plate 15 is first pulled to the left to be pulled away from the outer wall notch of the slide bar 11, and then the cover plate 12 is moved up and down on the outside of the slide bar 11 to move the cover plate 12 to the top of the test tube, and the cover plate 12 caps the top of the test tube, and then the L plate 15 is released, and the L plate 15 is inserted into the outer wall notch of the slide bar 11 under the elastic reset action of the positioning spring 19, so that the position of the cover plate 12 is fixed. When the mixed test tube is taken out, the second step is followed to move the entire cover plate 12 to the position as shown in the figure. Figure 1 The initial state is sufficient, and in actual operation, it is convenient to adjust the upper and lower positions of the cover plate 12, thereby improving the efficiency of the experimental operation.
