[0015] Preferably, the inner sidewall of the groove is provided with an abutment spring;

[0016] The abutting spring is designed with an arc shape, and the arched end of the abutting spring abuts against the side end of the test tube seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a test tube holder and a limiting strip, has the advantages of convenient operation, allowing the test tube holder to be removed and test tubes to be inserted externally, thus solving the problem of the inconvenience of placing multiple test tubes one by one in the small space inside the equipment.

[0019] 2. This utility model, by setting a slot and a plug, has the advantage that when placing the test tube holder, the slot and the plug are aligned to allow the test tube holder to be accurately inserted, and it is easy to insert into the groove.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0030] Example 1: An antibody extraction and purification device, see [link to example]. Figures 1 to 4 It includes the main body of the extraction and purification instrument 1, as well as the detection stage 2, the test tube holder 3 and the limiting strip 4;

[0031] The testing platform 2 is located at the bottom of the inner cavity of the extraction and purification instrument body 1; the test tube holder 3 is placed on the testing platform 2; wherein, a number of insertion holes 302 are equally spaced on the top side of the test tube holder 3, and the insertion holes 302 correspond to the tube heads set on the top of the inner cavity of the extraction and purification instrument body 1; two limiting strips 4 are symmetrically fixed on the top side of the testing platform 2; wherein, the two ends of the test tube holder 3 are inserted into the grooves 401 opened on the inner side of the two limiting strips 4.

[0032] This utility model, by setting up a test tube holder 3 and a limiting strip 4, has the advantages of convenient operation, allowing the test tube holder 3 to be removed and test tubes to be inserted externally, thus solving the problem of the inconvenience of placing multiple test tubes one by one in the small space inside the equipment.

[0033] Specifically, the rear end of the groove 401 is closed, and the test tube holder 3 can be limited after being pushed in, so that it can be accurately placed in the designated position.

[0034] Furthermore, two slots 201 are symmetrically provided on the top side of the testing table 2, and two inserts 301 are symmetrically fixed on the bottom side of the test tube holder 3. The inserts 301 are inserted and cooperate with the slots 201.

[0035] This utility model, by setting a slot 201 and an insert block 301, has the advantages of allowing the test tube holder 3 to be accurately inserted when it is placed, through the docking of the slot 201 and the insert block 301, and facilitating the insertion of the test tube holder 3 into the groove 401.

[0036] Furthermore, a rubber ring 303 is arranged inside the insertion hole 302. When the bottom of the test tube is inserted into the insertion hole 302, it contacts and compresses the rubber ring 303, thus stabilizing the insertion of the test tube.

[0037] It is worth noting that the inner wall of the groove 401 is provided with an abutment spring 402; the abutment spring 402 has an arc-shaped structure design, and the arched end of the abutment spring 402 abuts and cooperates with the side end of the test tube seat 3.

[0038] This utility model has the advantage of setting an abutting spring 402 to abut against the side end of the test tube holder 3 and keep the test tube holder 3 stable.

[0039] Working principle: Using the device of this invention, multiple test tubes are inserted one by one into the insertion holes 302. The bottom of the test tube is inserted into the insertion hole 302 and contacts the compression rubber ring 303. The test tube holder 3 is placed on the detection stage 2, and the insertion block 301 is inserted into the corresponding slot 201. The end of the test tube holder 3 is inserted into the groove 401 until the end of the test tube holder 3 is fully inserted into the groove 401. The arc-shaped abutment spring 402 is compressed, and the arched end of the abutment spring 402 abuts against the end of the test tube holder 3, positioning the test tube holder 3. The tube head at the top of the inner cavity of the extraction and purification instrument body 1 is lowered by the lifting structure and inserted into the corresponding test tube for antibody extraction and purification.

[0040] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
