[0034] Specifically, a circular groove is provided at one end of the connecting member 63 , and the connecting member 63 is sleeved on the outer wall of the transmission shaft 62 through the circular groove, and the other end of the connecting member 63 is connected to the transmission mechanism 5 .

[0035] like Figures 1 to 7The transmission mechanism 5 shown includes a supporting base plate 51 connected to the connecting member 63, a rotating belt assembly 52 is provided on one side of the supporting base plate 51, and the rotating belt assembly 52 includes a first roller 521 located at one end of the supporting base plate 51, a second roller 522 located at the other end of the supporting base plate 51, and a rotating belt 523 located between the first roller 521 and the second roller 522, one side of the rotating belt 523 is fixedly connected to the mounting base 60, and the other side of the rotating belt 523 is connected to the connecting mechanism 4;

[0036] Furthermore, the transmission mechanism 5 is connected to the driving mechanism 6 and the connecting mechanism 4 respectively through the supporting base plate 51 and the rotating belt assembly 52, which is conducive to reducing intermediate links, thereby improving the transmission efficiency and helping to reduce energy loss during the transmission process, so as to make the entire system more efficient.

[0037] Furthermore, the setting of the rotating belt assembly 52 makes the transmission process smoother.

[0045] Furthermore, the setting of the connecting groove 83 can increase the roughness of the contact surface between the first clamping seat 81 and the second clamping seat 82 and the rotating belt 523, so as to generate a greater bite force between the first clamping seat 81 and the second clamping seat 82 and the rotating belt 523 to prevent slipping.

[0047] Furthermore, the cooperation between the slide groove 71 and the slide rail 72 can ensure that the moving track of the connecting support 41 on the supporting base plate 51 is precisely controllable, which is helpful to reduce the occurrence of deviation and shaking.

[0048] Furthermore, the arrangement of the slide groove 71 and the slide rail 72 increases the stability of the connecting support 41 during the extension and retraction process, reduces the shaking or deviation caused by external force, and thus ensures the accuracy and reliability of the clamping work; secondly, the coordinated arrangement of the slide groove 71 and the slide rail 72 can disperse and bear the weight of the clamping assembly 2 and its load, which is beneficial to improving the load-bearing capacity and service life of the entire structure.

[0049] Furthermore, the cooperation between the slide groove 71 and the slide rail 72 is conducive to reducing the friction resistance generated during the extension and retraction process, and effectively improving the movement efficiency.

The supporting substrate 51 is connected to the transmission shaft 62 through the connecting piece 63, and the supporting substrate 51 follows the transmission shaft 62 to make telescopic movements. The side of the rotating belt 523 close to the driving motor 61 is fixedly connected to the mounting base 60 through the first clamping seat 81, and the side of the rotating belt 523 close to the supporting substrate 51 is fixedly connected to the connecting support 41 through the second clamping seat 82. When the driving shaft 62 descends in the vertical direction, the side of the rotating belt 523 connected to the first clamping seat 81 is fixed, and the connecting piece 63, the supporting substrate 51, the first roller 521, the second roller 522 and the side of the rotating belt 523 connected to the second clamping seat 82 all descend with the driving shaft 62, and the connecting support 41 is connected to the rotating belt 523 through the second clamping seat 82, so that the connecting support 41 further descends in the vertical direction.

[0051] like Figures 1 to 7 The clamping assembly 2 shown includes a telescopic motor 21, a telescopic rod 22 connected to the output end of the telescopic motor 21, an adjustment seat 23, a first clamping mechanism 24 located at one side of the adjustment seat 23 and movably connected to the adjustment seat 23, and a second clamping mechanism 25 located at the other side of the adjustment seat 23 and movably connected to the adjustment seat 23.

[0053] Furthermore, the relative distance between the first clamping mechanism 24 and the second clamping mechanism 25 is adjustable so that the clamping assembly 2 can achieve a more stable clamping effect, which helps to reduce the risk of shaking and falling of the test tube during the clamping process, and is beneficial to improving the safety of experiments or production.

[0056] like Figures 1 to 7 The first hinged member 262 shown includes a first horizontal portion 2621 arranged in the horizontal direction and connected to the first connecting rod 261, a first vertical portion 2622 arranged in the vertical direction and connected to the first clamping block 241, and a first hinged circular hole 2623 located between the first horizontal portion 2621 and the first vertical portion 2622 and hinged to the adjustment seat 23;

[0057] Specifically, when the telescopic motor 21 operates normally, the telescopic rod 22 connected to the output end of the telescopic motor 21 performs telescopic movement in the vertical direction, the first connecting rod 261 is connected to the telescopic rod 22, and the first connecting rod 261 moves up and down along the vertical direction following the telescopic rod 22. When the first connecting rod 261 moves downward, the first horizontal portion 2621 is subjected to a downward force, and the first horizontal portion 2621 moves downward following the first connecting rod 261. Since the first vertical portion 2622 and the first horizontal portion 2621 are hinged to the adjustment seat 23 through the first hinge circular hole 2623, so that the first hinge 262 can swing on the adjustment seat 23, the first horizontal portion 2621 is 21, one end connected to the first connecting rod 261 moves downward, and one end of the first horizontal portion 2621 connected to the first vertical portion 2622 moves upward, and the first vertical portion 2622 is connected to the first clamping block 241, thereby driving the first clamping block 241 to move toward the side away from the second clamping mechanism 25; when the first connecting rod 261 moves upward, one end of the first horizontal portion 2621 connected to the first connecting rod 261 moves upward, and one end of the first horizontal portion 2621 connected to the first vertical portion 2622 is subjected to a downward force, and the first vertical portion 2622 thereby drives the first clamping block 241 to move toward the side close to the second clamping mechanism 25.

[0058] like Figures 1 to 7 The adjustment seat 23 shown in the figure is provided with a sliding groove 231, and the first clamping block 241 is provided with a sliding member 2411 slidably connected to the sliding groove 231, so that the first clamping block 241 can move relative to the adjustment seat 23;

[0059] Furthermore, the sliding connection between the sliding groove 231 and the sliding member 2411 enables the first clamping block 241 to move relatively in the horizontal direction on the adjustment seat 23, which is beneficial for the first clamping block 241 to be flexibly adjusted in the horizontal direction to adapt to test tubes of different sizes and specifications, and is beneficial for enhancing the adjustment ability and applicability of the first clamping mechanism 24.

[0060] Optionally, in some embodiments, the sliding member 2411 includes a guide rail located on the first clamping block 241 , and the first clamping block 241 can move relatively in the horizontal direction on the adjustment seat 23 through the sliding fit between the sliding groove 231 and the guide rail.

[0061] Optionally, in some other embodiments, the sliding member 2411 includes a roller assembly located on the first clamping block 241 , and the roller assembly slidably cooperates with the sliding groove 231 so that the first clamping block 241 can move relatively in the horizontal direction on the adjustment seat 23 .

[0062] Furthermore, as a preferred embodiment of the present invention but not a limitation, the sliding member 2411 includes a sliding ball assembly located on the first clamping block 241, which is slidingly connected to the sliding groove 231 through the sliding ball assembly, so that the first clamping block 241 can move relatively in the horizontal direction on the adjustment seat 23.
