[0030] Fix the first installation frame 6 to the outside of the flange 4 connected to the flow meter body 1 with bolts, then sleeve the sealing ring 8 on the outside of the flange 4, push the second installation frame 7 along the connecting pipe 5 to slide it into the inside of the first installation frame 6, and when the second installation frame 7 moves to the terminal, fix the second installation frame 7 and the flange 4 connected to the connecting pipe 5 with bolts;

[0031] The first gear 10 is rotatably connected to the inside of the connecting disk 9, and the central axis of the first gear 10 extends through the inside of the first installation frame 6, and a torsion spring 11 is fixedly installed on the outside of the central axis of the first gear 10, and the other end of the torsion spring 11 is fixedly connected to the connecting disk 9, and a gear ring 12 is installed on the outside of the first gear 10, and the first gear 10 is meshed with the gear ring 12 for transmission, and the gear ring 12 is rotatably connected to the cavity opened in the inside of the connecting disk 9, and the connecting block 13 is slidably connected to the groove opened on the inner side of the gear ring 12, and the groove is arranged at equal angles along the center point of the gear ring 12, and the connecting block 13 is slidably connected to the inside of the groove opened in the connecting disk 9, and the connecting block 13 is arranged in an "L"-shaped structure, and the connecting block 13 is snap-connected to the groove at the left end of the second installation frame 7;
