[0028] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0029] The inventor's research found that currently, when detecting biological samples, test tubes are mostly manually taken one by one, and only 2-3 test tubes can be taken each time. The efficiency of test tube transfer is relatively low, and directly holding the test tube by hand may affect the samples in the test tube due to the temperature of the hand, thus affecting the test results of the samples.

[0030] Based on the above findings, the present application proposes a test tube clamping device, which connects the clamping plates by designing a rebound assembly. The operator pinches the top of the clamping plate with the hand and opens the clamping plate. When the hand is relaxed, the rebound assembly resets the bottom of the clamping plate, and multiple test tubes are clamped through the test tube card slots at the bottom, which has the advantages of simple structure, convenient use, high transfer efficiency and good reliability.

[0031] Refer to Figure 1 、 Figure 2 And Figure 3, this application discloses a test tube clamping device, including a pair of clamping plates 1. In some embodiments, the material of the clamping plates 1 can be selected from corrosion-resistant metal materials, or plastics or wood materials with high enough strength, etc., to ensure the durability of the clamping plates 1 and make the clamping plates 1 not prone to breakage; the pair of clamping plates 1 are rotatably connected through a resilient component 2. The operator pinches the top of the clamping plates 1 to make the clamping plates 1 in an open state, inserts the test tube through the gap opened in the middle of the clamping plates 1, and then slowly releases the clamping plates 1. Through the resilient action of the resilient component 2, the clamping plates 1 are reset, and the test tube is clamped by the test tube clamping groove 3.

[0032] Refer to Figure 4 , Figure 5 and Figure 6 , the resilient component 2 includes a boss 201 fixed to one end of the clamping plate 1 near the top. In some embodiments, to ensure reliable relative rotational movement between the pair of clamping plates 1, the shape, size, and number of the bosses 201 on each individual clamping plate 1 should be the same, and the number of the bosses 201 should be no less than 2;

[0033] The bosses 201 on the two clamping plates 1 are closely attached to each other, and a connecting shaft 202 is penetrated through the middle of the side cross-section of the boss 201. In some embodiments, an end cap or a limiting member can be installed at the connection between the connecting shaft 202 and the outermost two bosses 201 to prevent the connecting shaft 202 from falling off the boss 201. At the same time, to ensure the durability of the connecting shaft 202, its material should be selected from high-strength metal materials with corrosion resistance; a return spring 203 is sleeved on the connecting shaft 202, and both ends of the return spring 203 are fixed to the inner end surfaces of the bosses 201. When the operator pinches the top of the clamping plates 1, at this time, the bosses 201 rotate relative to each other, and the return spring 203 starts to contract under the action of the relatively directed forces generated by the rotation. When the hand slowly releases the clamping plates 1, the return spring 203 restores its deformation, thereby driving the bosses 201 to rotate in the opposite direction, and at the same time resetting the clamping plates 1 and clamping the test tube located between the bottoms of the two clamping plates 1.

[0034] A plurality of test tube clamping grooves 3 capable of clamping a plurality of test tubes are fixed to the bottom of the clamping plate 1. In some embodiments, the number of the test tube clamping grooves 3 is 7, and the number of the test tube clamping grooves 3 can be increased or decreased in pairs according to the actual application scenario;

[0035] Refer to Figure 7 and Figure 8, in some embodiments, at the bottom of one side of the splint 1 where the test tube slot 3 is fixed, there are 7 test tube slot mounting grooves 101. On one side of the test tube slot 3 connected to the splint 1, there is a test tube slot mounting key 301. The cross-sectional shapes of the test tube slot mounting groove 101 and the test tube slot mounting key 301 should be as similar as possible, and the cross-sectional dimensions should match each other. As shown in the figure, the cross-sectional shapes of the test tube slot mounting groove 101 and the test tube slot mounting key 301 are both cross-shaped with a certain thickness. According to the actual situation, the test tube slot mounting key 301 can also be processed into other shapes except circular to prevent the test tube slot 3 from rotating when clamping the test tube, thereby affecting the test tube clamping efficiency or causing the test tube to fall off and break. At the same time, through the keyway connection method, the test tube slot is easy to disassemble and replace, and it is not easy to fall off during use.

[0036] At the same time, as Figure 8 shown, the cross-sectional shape of the test tube slot 3 can be selected as a semi-circular ring shape, or a test tube slot 3 that matches different test tube shapes can be manufactured, such as the rectangular ring shape shown in the figure, so that multiple different-shaped test tubes can be clamped at one time when clamping, improving the scope of application and functionality of the present utility model. At the same time, the thickness of the test tube slot 3 can also be adjusted according to the different cross-sectional dimensions of the test tube, so that when the splint 1 is tightened, it can just fit the test tube wall to clamp the test tube;

[0037] On the surface of the test tube slot 3 in contact with the test tube wall, sponge or rubber pads can be added to increase the friction between the test tube slot 3 and the test tube, improving the transfer efficiency. And the sponge or rubber pads themselves have a certain elasticity, which can play a buffering role when clamping the test tube, preventing the test tube from breaking and improving the reliability of the present utility model.

[0038] On both sides of the top of the splint 1, semi-circular chamfers are provided, which can make its shape more conform to the shape of the human hand, improving the usability of the present utility model while achieving a beautiful appearance; at the same time, the length of the cross-section of the top of the splint 1 is shortened, at most not exceeding 1 / 4 of the length of its bottom cross-section, which is convenient for the operator to hold.

[0039] First, place the test tubes to be clamped vertically in a row. The operator pinches the top of the splint 1 with fingers to open the splint 1 from the bottom. Then, insert the test tubes into the gap between the two opened splints 1. Slowly release the top of the splint 1. At this time, the return spring 203 in the return spring assembly 2 drives the splint 1 to gradually return to its original position. The multiple test tube slots 3 at the bottom of the splint 1 gradually fit the outer wall of the test tube and clamp the test tube. When the fingers are completely relaxed, the splint 1 completes the return through the return spring assembly 2. At this time, the test tube slots 3 complete the clamping of multiple test tubes. For test tubes with different cross-sectional shapes, the test tube slots 3 can be replaced according to the cross-sectional shape of the test tube. At the same time, sponge or rubber pads can be added to the test tube slots 3 to improve the clamping effect on the test tube and prevent the test tube from being damaged.
