A telescopic spring 42 is installed on the inner side of the control shaft 41, a ring plate 43 is fixedly connected to the outer side of the middle of the control shaft 41, and a damping convex cam is fixedly connected to the upper end of the ring plate 43. There are multiple points 44; the adjusting plate 7 includes a circular plate 71, and grooves 72 are provided on the inner sides of the circular plate 71. A column shell 73 is fixedly connected in the middle of the groove 72, and a first positioning hole 74 distributed in an annular manner and equidistantly is provided on the inner side of the upper end of the column shell 73; the turntable 8 includes a turntable body 81, and a plurality of first inclined holes 82 are distributed in an annular manner on the inner side of the turntable body 81; the aperture adjustment mechanism 15 includes a hollow plate 151 arranged in an annular manner, and a gear ring 152 is welded and fixed to the upper end of the hollow plate 151, and second inclined holes 153 are provided in an annular manner and equidistantly on the inner side of the hollow plate 151, and a clamping mechanism 154 is installed inside the second inclined hole 153, and the clamping mechanism 154 includes an elastic bent rod 1541, and the upper end of the elastic bent rod 1541 is fixedly connected to a positioning column 1542 with a horizontal projection of a T.

[0040] according to Figure 1 and Figure 5 As shown, the adsorption mechanism 6 is specifically as follows: a plurality of bottom plate circular holes 5 are equidistantly opened in a ring shape on the inner side of the lower bottom plate 3, and an adsorption mechanism 6 is installed in the middle of each bottom plate circular hole 5. The adsorption mechanism 6 includes an adsorption block 61, a rubber ring 62 is fixedly connected to the outer middle side of the adsorption block 61, a center hole 63 is opened in the middle of the adsorption block 61, a groove adapted to the bottom of the test tube is opened at the upper end of the adsorption block 61, and a groove with a trapezoidal cross section is opened at the lower end of the adsorption block 61. The bottom end of the adsorption block 61 and the bottom end of the lower bottom plate 3 are arranged at the same horizontal plane, and the outer side of the rubber ring 62 is fixedly connected to the inner wall of the bottom plate circular hole 5. When the test tube is placed inside the test tube rack, the upper end of the center hole 63 can be sealed by the test tube, thereby achieving the effect of positioning the test tube rack as a whole;

[0041] according to Figure 1 、 Figure 2 and Figure 6 As shown, the through-holes 9, the column shell 73, and the bottom plate circular hole 5 are provided. Specifically, the vertical cross-section of the top plate 1 is U-shaped, and the top plate 1 is annularly and equidistantly provided with through-holes 9. The through-holes 9 correspond to the column shell 73 and the bottom plate circular hole 5 in a one-to-one correspondence, which can effectively position the test tube.

[0042] according to Figure 1 、 Figure 6 as well as Figure 10 As shown, the positioning ring 11 is provided, specifically: the upper end of the adjustment plate 7 is fixedly connected to the limiting ring 11, and the bottom end of the limiting ring 11 is annularly and equidistantly provided with second positioning holes 13, and the second positioning holes 13 and the tooth plate 14 correspond one to one. The tooth plate 14 is slidably connected to the limiting ring 11 through the second positioning holes 13, which can stably limit the movement of the tooth plate 14, thereby improving the stability of the tooth plate 14 during movement;

[0043] according to Figure 1 、 Figure 4 and Figure 6-10 As shown, the adjustment plate 7, the turntable 8, the hexagonal prism 10 and the aperture adjustment mechanism 15 are provided, specifically: the circular plate 71 is rotatably connected to the hollow plate 151 through the groove 72 provided therein, the groove 72, the hollow plate 151 and the column shell 73 are coaxially arranged, and the upper end surfaces of the hollow plate 151 and the circular plate 71 are arranged at the same horizontal plane, which can improve the stability of the test tube during placement;

[0044] The elastic bent rod 1541 is L-shaped and is slidably connected to the column housing 73 through the first positioning hole 74. Four elastic bent rods 1541 are provided for sliding connection to the inner side of the upper end of each column housing 73, which can stably limit the position of the test tube so that the test tube can be stably placed inside the test tube rack.

[0045] The tooth plate 14 is meshed with the ring gear 152. The angle between the tooth plate 14 and the circular shaft 12 is 90°. The circular shaft 12 is rotatably connected to the turntable body 81 through the first inclined hole 82. The turntable body 81, the circular plate 71, the lower base plate 3, the support column 2 and the upper top plate 1 are coaxially arranged. The ring gear 152 can be driven to rotate by the movement of the tooth plate 14.

[0046] The upper end of the hexagonal prism 10 is fixedly connected to the lower end of the telescopic spring 42, and the hexagonal prism 10 is slidably connected to the lower end of the control shaft 41. The ring plate 43 fixed in the middle of the control shaft 41 is tightly attached to the middle of the upper end of the upper top plate 1 through the damping protrusion 44. A ring-shaped rubber pad is installed on the inner side of the middle of the upper end of the upper top plate 1, which can stably limit the control shaft 41, thereby ensuring the stability of the elastic bent rod 1541 after adjustment.

[0047] Workflow: When using a turntable test tube rack with adjustable aperture, the staff places the test tube rack on the inspection table. After placement, the structure used to fix the test tubes is adjusted according to the size of the test tubes to ensure stable positioning of test tubes of different sizes.

[0048] During the adjustment process, the control shaft 41 is controlled to move downward, so that the ring plate 43 is separated from the rubber pad installed at the middle inner position of the upper end of the upper top plate 1, and then the control shaft 41 is controlled to rotate. When the control shaft 41 rotates, the turntable body 81 is driven to rotate through the hexagonal prism 10, and then the gear plate 14 is controlled to move through the first inclined hole 82 opened inside the turntable body 81. In the process of moving along the direction of the corresponding second positioning hole 13, the gear plate 14 drives the gear ring 152 to rotate. In the process of rotation, the gear ring 152 drives the hollow plate 151 to rotate, and then controls the synchronous movement of the multiple elastic bent rods 1541 through the second inclined hole 153. By adjusting the distance between the multiple elastic bent rods 1541 and the central axis of the column shell 73, the multiple elastic bent rods 1541 can be cooperated to achieve the clamping and positioning of test tubes of different sizes;

[0049] After the size adjustment of the test tube is completed, the test tube is passed through the perforation 9 and the elastic bent rod 1541. Multiple elastic bent rods 1541 can be used to ensure the stability of the test tube after being placed on the test tube rack (to prevent the placed test tube from tilting due to the large hole). The test tube is continued to be controlled to move downward and the bottom of the test tube is tightly attached to the upper end of the adsorption block 61. In the process of the bottom of the test tube being tightly attached to the upper end of the adsorption block 61, the test tube seals the upper end of the center hole 63 and causes the adsorption block 61 to move slightly downward as a whole. At this time, the adsorption block 61 cooperates with the T-shaped groove opened at the bottom end to be adsorbed together with the inspection table, thereby improving the stability of the test tube rack as a whole when placed on the inspection table. Later, after all the test tubes placed inside the test tube rack are taken out, the upper ends of the center holes 63 opened on the inner sides of all adsorption blocks 61 are in an open state, thereby causing the bottom end of the adsorption block 61 to no longer be adsorbed to the inspection table, and the test tube rack can be directly taken away from the inspection table.
