At this time, the two half-ring plates (5) are correspondingly buckled on the outer sides of the upper ring edge (6) and the lower ring edge (7). The half-ring plates (5) are matched with the inner ring groove (9) to define the upper ring edge (6) and the lower ring edge (7). After the two half-ring plates (5) are buckled respectively, the two opposite clamping plates (11) are matched with each other; S3, rotating the rotating sleeve (22), the rotating rotating sleeve (22) rotates on the outside of the ring sheet (21), and the rotating rotating sleeve (22) drives the square rod (20) to rotate by using the square groove, and the rotating square rod (20) drives the rotating rod (16) to rotate between the two opposite side edges (10), and the rotating rotating rod (16) reels the winding sheet (19), and the wound winding sheet (19) is wound on the outside of the rotating rod (16), and the wound winding sheet (19) pulls the clamping plate (11) close to the rotating rod (16), at this time, the two clamping plates (11) gradually approach each other, and the two opposite clamping plates (11) are both buckled on the outside of the rotating rod (16) by using the groove (17), and the two opposite side edges (10) use the two clamping plates (11) to block the gap between the two side edges (10), and at this time, the wound winding sheet (19) is located on the inner side of the rotating groove (18); S4, the moving card plate (11) drives the card edge (14) to move synchronously until the two opposite card edges (14) are correspondingly fitted, the two top card edges (14) correspondingly block the gap between the upper ring edge (6) and the card plate (11), and the two bottom card edges (14) correspondingly block the gap between the lower ring edge (7) and the card plate (11); S5, pull the rotating frame (29), the rotating frame (29) drives the threaded sleeve close to the contact plate (26), and inserts the inserting frame into the inner side of the slot (23) until the threaded sleeve corresponds to the screw rod (28), and twists the rotating frame (29). The rotating rotating frame (29) is spirally sleeved on the surface of the screw rod (28) by the threaded sleeve, so that the semi-ring plate (5) is stably buckled on the outer side of the upper ring edge (6) and the lower ring edge (7), thereby completing the connection between the feed pipe (2) and the liquid pipe (3).
