According to the single extraction low-temperature storage device for intelligent technological biological products according to claim 7, the support column is made of a material with low thermal conductivity, and the material of the support column can be selected from carbon fiber, glass fiber, epoxy glass fiber; the The central column is made of materials with low thermal conductivity, and the material of the central column can be selected from carbon fiber, glass fiber, epoxy glass fiber; the central column is made of aluminum alloy material with high thermal conductivity. The single-root extraction low-temperature storage device for intelligent technology biological products as claimed in claim 8 includes a positioning module, the positioning module is a trigger rod disposed on one of the support bases, and disposed at the end of the robotic arm And the position corresponds to a trigger button of the trigger lever of the mechanism, when the transmission mechanism rotates one of the support bases to the corresponding extraction portion, the trigger lever contacts the trigger button; or, the positioning module is provided in the mechanism An infrared sensor at the end of the arm, a hole is set on one of the support bases corresponding to the position of the infrared sensor, when the transmission mechanism rotates one of the support bases to the corresponding extraction part, the infrared The sensor detects a distance change according to the hole. According to claim 9, the single-root extraction low-temperature storage device for biological products of intelligent technology is provided with a detector and a vacuum valve in the casing, the detector monitors the vacuum degree of the space, and the vacuum valve is connected to the vacuum valve. The space is separated, and the backstop is directly after the vacuum is exhausted.
