Three-axis movement sampling mechanism and full-automatic genital tract secretion detector

The invention discloses a three-axis motion sampling mechanism which comprises a rack and a multi-axial motion unit, and the multi-axial motion unit is arranged in the rack and is composed of an X-axis motion mechanism, a Y-axis motion mechanism and a Z-axis motion mechanism; the cantilever supporting mechanism is arranged on the rack; the sampling part is arranged on the Z-axis movement mechanism and is used for sampling a lower sample; wherein the Y-axis movement mechanism is of a cantilever type, and the cantilever supporting mechanism is arranged at the cantilever end of the Y-axis movement mechanism and used for supporting the Y-axis movement mechanism. The device has the advantages that the deflection amount of the cantilever end is greatly reduced, so that the sampling part can quickly and stably perform sampling work; in the sampling process, the lower end supporting bearing can make contact with the lower surface of the supporting strip under the action of force when the sampling part ascends, meanwh
