The multiple test tube mounting components 531 are arranged around the circumferential side of the gear disk to form a test tube mounting group. Among them, the number of test tube mounting groups is n, and the n groups of test tube mounting groups are arranged in sequence along the radial direction of the gear disk, where n≥1. In this way, there are multiple test tube mounting components 531. The multiple test tube mounting components 531 are arranged around the circumferential side of the gear disk to form a test tube mounting group. Multiple gear members are installed on the circumferential side of the gear disk in an annular arrangement, and the gear members are respectively meshed with the gear disk. This method can save space during installation. At the same time, this method can drive multiple gear members to rotate synchronously with one gear disk, with fewer transmission times and high efficiency. In addition, the situation where the operation of the entire nucleic acid extraction and amplification integrated detection device is affected by the damage of one gear member will not occur, enhancing the stability of the nucleic acid extraction and amplification integrated detection device. On the other hand, the annular arrangement structure is simpler and more compact, making the heating of the amplification device 52 more concentrated, enabling more uniform heating, with a smaller temperature difference between each test tube, and improving the uniformity. Among them, the number of test tube mounting groups is n, and the n groups of test tube mounting groups are arranged in sequence along the radial direction of the gear disk, where n≥1.

[0178] When n is 1, the gear members are wound around the circumferential side of the gear disk to form a circular structure. When n is 2, the gear members are wound around the circumferential side of the gear disk to form a circular structure, which is the inner gear ring. Multiple gear members are wound outside the inner gear ring to form another circular structure, which is the outer gear ring. At this time, the outer gear ring is meshed with the inner gear ring. The rotation of the gear disk can drive the rotation of the inner gear ring, and the outer gear ring will rotate accordingly, realizing the synchronous rotation of the inner gear ring and the outer gear ring.

[0179] It can be understood that the gear members located on the outer gear ring are meshed with two adjacent gear members located on the inner gear ring, that is, the gear members located on the outer gear ring are staggered with the gear members located on the inner gear ring to achieve synchronous transmission. n can also be 3, 4 or more, and the setting method of the gear members can be inferred by analogy. Preferably, n in this embodiment is 2, and each gear ring has 16 gear members, which can simultaneously realize the extraction and amplification of nucleic acids of multiple samples, improving the efficiency of nucleic acid extraction and amplification, and achieving a single-module multi-flux setting in terms of structure.
