The outer wall of the sealing ring 43 is fixedly connected to the inner side of the top of the fixing groove 410. The inner wall of the connecting collar 41 is fixedly connected to the outer wall of the first pipeline 1. The locking blocks 42 are made of iron. The number of locking blocks 42 is equal to the number of sockets 203. The outer wall of the locking block 42 passes through the socket 203 and engages with the inner wall of the slot 204.
