Multi-functional single-particle sequencing device

The utility model discloses a multi-functional single-particle sequencing device. The multi-functional single-particle sequencing device can perform single-particle sampling, sequencing and separation on regular or irregular particle objects. The multi-functional single-particle sequencing device mainly comprises a base, a support A, a support B, a turntable, a material trough, a transmission shaft, a suction nozzle, a hose, a hose connector, a bearing A, a bearing B, a bearing end cover, a scraping groove, an external air suction head and a collection box. The main innovation is that: a hollow shaft is sleeved in a central inner hole of the transmission shaft; and rotating shaft sealing pieces are arranged in the central inner hole on the rear part of the transmission shaft so as to ensure that a sealing vacuum chamber is formed by the space between the inner hole surface of the front part of the transmission shaft and the outer circle surface of the front part of the hollow shaft. The multi-functional singl
