fourthly, after the inner clamping plate (2) completely extends into the pipeline (1), the second handheld part (6) is held by a hand to pull up the driving rod (4), after the driving rod (4) moves upwards to the upper end of the inner clamping plate (2) to touch the inner wall of the pipeline (1), the driving rod (4) continues to move upwards to enable the inner clamping plate (2) to rotate, and when the inner clamping plate (2) rotates to the state that the two ends touch the inner wall of the pipeline (1), the driving rod (4) can not be pulled up any more; at the moment, the outer clamping plate (3) is sleeved on the driving rod (4) in a penetrating manner, so that the positioning hole (7) on the corresponding side is sleeved on the outer side of the corresponding driving rod (4); then, a through hole (12) of the positioning block (8) is sleeved with the free end of the driving rod (4), the positioning block (8) is sleeved on the driving rod (4), the first handheld part (9) is rotated, the first external thread (10) and the second internal thread (13) rotate along with the first external thread (10) and the second internal thread (13), the positioning block (8) is screwed into and fixed in the positioning hole (7) due to the matching effect of the first external thread (10) and the first internal thread (11), meanwhile, the driving rod (4) is fixed in the through hole (12) due to the matching effect of the second external thread (14) and the second internal thread (13), and the fixing of the inner clamping plate (2) and the outer clamping plate (3);
fifthly, combining the upper hoop (152) and the lower hoop (153) to surround the outer side of the outer clamping plate (3) and the pipeline (1), clamping the clamping part (151) in the hoop groove (16), then connecting the flanges (17) at the corresponding sides of the upper hoop (152) and the lower hoop (153) by using a fixing bolt (18) and screwing a nut (19), and finally completing the installation of the leakage stopping device of the water supply and drainage pipeline.
