The round balls are in contact with the outer surface of the inner shell and are located inside the second annular groove. Grease is injected into the first annular groove and the second annular groove. A fixing rod is installed on the sealing ring. The fixing rod extends into the outer shell. A moving block is provided on the side of the sealing ring close to the outer shell.
[0006] Preferably, the fixed rod and the moving block are arranged close to each other, an integrally formed protrusion is provided on one side of the fixed rod, the top of the fixed rod is threadedly connected to the shell, and a sealing strip is installed between the fixed rod and the sealing ring, and the protrusion can contact the moving block after entering the shell.
[0007] Preferably, the moving block is wedge-shaped, and a folding plate installed with screws is provided on one side of the narrow side of the moving block.
