First, the cover 200 is opened, the water meter 300 is placed in the installation groove at the bottom of the case 100, and at this time, the water meter 300 is limited at the center of the case 100 and cannot move. Then, the driving handle 401 is rotated clockwise, the tension spring is gradually stretched through the rotation of the driving handle 401, when the driving handle 401 rotates to the right side of the sliding frame 510, the tension spring is contracted to further pull the sliding frame 510 to slide along the sliding groove 101 towards the direction of the connecting pipe 800, and as the sealing sleeve 710 is arranged in the sliding frame 510 and is in blocking fit with the water pipe 600, the sealing sleeve 710 moves to drive the water pipe 600 to slide towards the connecting pipe 800 to press the sealing ring 900, and the sealing ring 900 deforms along the radial direction after being pressed, so that the tight connection of the water pipe 600, the connecting pipe 800 and the sealing sleeve 710 is realized.
At this time, the second rotating ring 740 enters the inside of the connection pipe 800, and then the rotating frame 540 is rotated clockwise, so that the first gear 541 drives the first double-sided rack 520 and the second double-sided rack 530 to move in opposite directions, as shown in fig. 15, assuming that the first rotating ring 720 is rotated clockwise, the second rotating ring 740 is rotated counterclockwise, the counterclockwise rotation of the second rotating ring 740 not only axially presses the friction block 833 in the rotating ring 830, so that the friction block 833 moves along the radial direction of the rotating ring 830, the rotation of the second rotating ring 740 also drives the rotating ring 830 to rotate through the friction block 833, so that the negative magnet 832 on the rotating ring 830 is not attracted with the wedge block 820 any more, Instead, the positive magnet 831 on the rotating ring 830 repels the wedge block 820, so that the rotating ring 830 pushes the wedge block 820 to move axially leftwards, and then the inclined surface of the wedge block 820 cooperates with the inclined surface of the clamping block 810 to drive the clamping block 810 to move radially into the limiting clamping groove 744, thereby realizing axial locking of the second rotating ring 740 and the connecting pipe 800. Then, the rotating frame 540 is continuously rotated clockwise, the first rotating ring 720 is continuously rotated clockwise, the second rotating ring 740 is continuously rotated anticlockwise, so that the elastic strips 730 in the second limiting groove 722 and the fourth limiting groove 742 are stretched, the end parts of the elastic strips are always positioned at the innermost ends of the second limiting groove 722 and the fourth limiting groove 742, the elastic strips 730 in the first limiting groove 721 and the third limiting groove 741 are integrally moved outwards in a radial direction, the diameter of a circle formed by the elastic strips is enlarged, and the two elastic strips 730 are distributed inside and outside and are staggered in the radial direction, so that mutual interference is avoided; the elastic strip 730 on the inner side stretches to enable the first swivel 720 and the second swivel 740 to have acting force close to each other, and as the first swivel 720 is connected with the sealing sleeve 710 and the sealing sleeve 710 is in stop fit with the water pipe 600, the water pipe 600 and the connecting pipe 800 have acting force close to each other, and the connection stability of the water pipe 600 and the connecting pipe 800 is improved; And because the inner elastic strip 730 is twisted, the middle position of the inner elastic strip 730 radially contracts and deforms towards the central axis of the sealing sleeve 710, so that radial extrusion can be generated on the sealing sleeve 710, the sealing sleeve 710 can further seal the water pipe 600 and the connecting pipe 800, and the sealing effect is improved. Finally, the rotating frame 540 is pulled upwards, so that the limiting block 542 is matched with the limiting hole 515, the locking of the rotating frame 540 is realized, and the sealing sleeve 710 is kept in a sealing state. When the water meter 300 needs to be replaced, the rotating frame 540 is pressed downwards to enable the first toothed ring 724 to be meshed with the first double-sided rack 520 and the second double-sided rack 530 again, and then the first rotating ring 720 and the second rotating ring 740 are driven to reset; finally, the driving handle 401 is rotated to the left side of the sliding frame 510, so that the unlocking of the water meter 300 can be realized, and finally, the water meter 300 can be removed. When the water meter 300 is installed next time, the rotating frame 540 is reversely rotated, so that the last stretched elastic strip 730 moves radially, and the last radially moved elastic strip 730 deforms in a stretching manner, so that the elastic strip 730 alternately deforms in a stretching manner, the service life of the elastic strip 730 is prolonged, and the sealing effect is ensured.
