According to the technical scheme, the movable ring structure of the impact-resistant tail shaft sealing device comprises a movable ring, and the movable ring comprises two movable ring bodies which are connected in a spliced mode; the movable ring body comprises a connecting bolt, the connecting bolt is arranged on the half face of the movable ring body, and the axial direction of the connecting bolt is perpendicular to the combination face of the movable ring body. The movable ring body comprises a first cylindrical pin and a second cylindrical pin, a pin hole is formed in the half face of the movable ring body, the first cylindrical pin is inserted into the pin hole, and the second cylindrical pin is inserted into the first cylindrical pin. The semi-movable ring has the advantages that the good positioning effect on the working face of the semi-movable ring body is achieved, the flatness is improved, and the service life of the semi-movable ring body is prolonged. The sealing performance of the sealing device is facilitated.
