[0025] Working principle: During installation, the static disk housing 2 drives the sealing ring 8 to be inserted into the sealing groove 4 to improve the connection sealing. At this time, the mounting plate 3 is inserted into the inner cavity of the positioning shell 5, and then the torsion block 63 is twisted to drive the screw 62 to rotate in the inner cavity of the threaded sleeve 61. While the screw 62 rotates, the threaded ring 64 drives the connecting plate 65 to move. When the connecting plate 65 moves, it drives the sliding sleeve 66 to move on the surface of the sliding rod 67. As the sliding sleeve 66 moves, it drives the positioning ring 69 to move the tension spring 610. As the sliding sleeve 66 moves, it drives the clamping plate 68 to be inserted into the mounting plate 3, thereby facilitating the connection and installation between the static disk housing 2 and the dynamic disk housing 1. The dynamic disk housing 1 can be separated from the static disk housing 2 by rotating the torsion block 63 in the opposite direction.
