Ball seat of test tube suspension sealing device

The utility model relates to the technical field of suspension sealing devices, and discloses a ball seat of a test tube suspension sealing device, which comprises an upper joint, a cone mechanism, a slip body mechanism and a sealing assembly, and is characterized in that the side surface of the upper joint is movably connected with the side surface of the slip body mechanism through a pin; the side face of the slip body mechanism is movably connected with the inner wall of the side face of the sealing assembly, and the inner wall of the side face of the sealing assembly is movably connected with the side face of the cone mechanism. Equipment is extruded from the two ends through a setting tool, so that the cone body moves towards the inner wall of the slip body mechanism, and when the side face of the rolling wheel makes contact with the inner wall of the side face of the slip body main body and extrudes the inner wall of the side face of the slip body main body for blocking, the side face of the cone body m
