8. The method for sampling a microbiological sampling apparatus according to claim 7, comprising the steps of:
the telescopic link of upset cylinder drives the slider is followed the direction arch moves, and then makes the slider passes through sharp tooth drives drive gear rotates, drive gear drives in the rotation process the clamping structure carries out tilting motion, and then adjusts the orientation of clamping structure and sample test tube through this kind of tilting motion.
9. The method of sampling a microbiological sampling apparatus according to claim 8, comprising the steps of:
when the object to be sampled is sampled through the sampling test tube, the rotating motor drives the supporting roller body to rotate, and the supporting roller body rotates and samples the clamped sampling test tube to finish the sampling work of the object to be sampled.
