At this time, the connecting pipe 3 is inserted into the outer surface of the water pipe, and the circular ring is no longer pressed. 7 applies a thrust, and at the same time, the two first springs 5 ​​are no longer under stress. At this time, the two first springs 5 ​​expand, and the two first springs 5 ​​apply a rightward thrust to the two pressure plates 6 fixedly installed at the right end, so that they move to the right. When the two pressure plates 6 move to the right, they hit the fixed block 12 and apply a relative thrust to the two fixed blocks 12. At this time, the two fixed blocks 12 apply a relative thrust to the two fixed rods 10 fixedly installed on the opposite surfaces, so that they move toward the opposite surfaces. At the same time, the two fixed rods 10 apply a relative thrust to the fixing rings 13 fixedly installed on the opposite surfaces, so that they move toward the opposite surfaces and fit the outer surface of the water pipe for clamping and fixing, and the first rubber sealing ring 14 and the second rubber sealing ring 14 fit the outer surface of the water pipe for sealing.
