Efficient nucleic acid extractor

The invention provides an efficient nucleic acid extractor, which comprises a casing, and a driving assembly, a magnetic bar assembly, a magnetic sleeve assembly, a heating assembly and a bearing assembly arranged in the casing, the driving assembly is used for controlling the magnetic bar assembly and the magnetic sleeve assembly to move transversely and longitudinally, and the bearing assembly comprises a support plate and a heating body, the supporting plate is horizontally arranged in the machine shell, a rectangular notch used for containing a heating body is formed in the supporting plate, the heating effect is good, the temperature rise speed is high, the extraction efficiency is high, the time spent in the splitting decomposition and elution steps is greatly shortened, meanwhile, the vibration unit is additionally arranged, the supporting frame can be driven to vibrate horizontally, the magnetic sleeve vibrates in the horizontal direction, and therefore the magnetic sleeve can be effectively separated
