[0002] The PCR tube body is made of USP-certified imported medical-grade highly transparent polypropylene as raw material, with a smooth surface to ensure high efficiency and uniformity between samples. It meets the requirements of accurate and efficient PCR reactions and is used in gene testing, disease diagnosis, drug development and other fields. The PCR tube body is usually set to be transparent, because the transparency and absence of impurities can reduce the influence of scattered light.

[0003] At present, the top of the PCR tube body is sealed with a pressure cap to seal the inside of the PCR tube body. The outside of the pressure cap lacks a reinforcement structure. The cover body expands due to the amplification reaction, which can easily cause the pressure cap to loosen and affect the sealing of the PCR tube body, thus affecting the service life of the PCR tube body. In addition, when the PCR tube body is sealed, the ring sleeve mounted on the outer wall of the PCR tube body needs to adapt to the thickness of the tube body, which cannot be flexibly applied to PCR tubes of various specifications, thereby increasing the investment cost.

A fixing component 3 is arranged at the middle end of the lower ring sleeve 21, and the fixing component 3 includes an adjuster 31, and a connector 32 is fixedly connected to the side surface of the adjuster 31, and the connector 32 passes through the lower ring sleeve 21 and is rotatably connected to the lower ring sleeve 21.

[0026] The bottom end of the connector 32 is fixedly connected with a fixture 33, and the fixture 33 includes a wrapping plate 331. The wrapping plate 331 is concave and matches the shape of the outer wall of the PCR tube body 11 and can slide on the outer wall of the PCR tube body 11. The surface of the convex teeth 333 is rough. The wrapping plate 331 is concave and fixedly connected with receiving plates 332 on both sides. The upper surface of the receiving plate 332 is fixedly connected with convex teeth 333. When the direction of the adjuster 31 is parallel to the side of the lower ring sleeve 21, the fixture 33 wraps the outer wall of the PCR tube body 11 and can slide up and down on the outer wall of the PCR tube body 11. When the direction of the adjuster 31 is perpendicular to the side of the lower ring sleeve 21, the convex teeth 333 are tightly attached to the outer wall of the PCR tube body 11 and are not easy to slide and change position. The convex teeth 333 are made of rubber material, which has a certain viscosity and can generate a large friction force after contacting the outer wall of the PCR tube body 11.
