Antibody sample extraction device for antibody recombination

The antibody sample extraction device comprises a stable base, a rubber suction cup, a supporting column, a rectangular connecting column, an adjusting structure and a pipettor fixing structure, the rubber suction cup is fixedly installed on the bottom face of the stable base, and the supporting column is fixedly connected to the upper surface of the stable base; an adjusting structure is installed on the supporting column, a ball head is rotationally arranged at one end of the rectangular connecting column, a limiting bolt is arranged on the outer surface of the rectangular connecting column in a threaded mode, one end of the limiting bolt abuts against the ball head, and a pipettor fixing structure is fixedly installed at one end of the ball head; the pipettor can be stably fixed, so that the pipettor is more stable and accurate during use, one end of the pipettor can enter an antibody culture device flexibly by matching with an adjusting structure, suction and extraction are carried out, and the pipettor f
