First fixing blocks 13 are fixedly installed at the tops of the two first positioning rings 12. A support plate 14 is arranged at the top of the first fixing block 13. Symmetrically distributed first connecting rods 15 are fixedly installed at one side of the top of the support plate 14. Second connecting rods 16 are arranged at the sides away from the support plate 14 of the two first connecting rods 15. An installation plate 17 is fixedly installed at the common bottom ends of the two second connecting rods 16. An empty groove 18 is opened in the middle of the top of the installation plate 17. Guide rods 19 are fixedly installed on the opposite sides of the inner wall of the empty groove 18. Symmetrically distributed second fixing blocks 191 are movably sleeved on the outer sides of the guide rods 19. First springs 192 are fixedly installed on both sides of the inner wall of the empty groove 18. The two first springs 192 are respectively fixedly connected to the corresponding second fixing blocks 191. Second positioning rings 193 are fixedly installed at the bottom ends of the two second fixing blocks 191. Stabilizing plates 194 are fixedly installed at the top ends of the two second fixing blocks 191. The stabilizing plates 194 are in contact with the top of the installation plate 17. Symmetrically distributed pins 195 movably penetrate through the top ends of the two stabilizing plates 194. Uniformly distributed through holes 196 are opened on both sides of the top of the installation plate 17. The pins 195 are used in cooperation with the through holes 196. During actual use, first, the first positioning rings 12 and the second positioning rings 193 are placed above the connecting pipe 11 and the pipeline to be cut. Then, the first positioning rings 12 and the second positioning rings 193 are moved downward so that the connecting pipe 11 and the pipeline to be cut respectively enter the spaces between the first positioning rings 12 and the second positioning rings 193. Then, the first positioning rings 12 are installed on the connecting pipe 11. At this time, by moving the two stabilizing plates 194, the second fixing blocks 191 are driven to move on the guide rods 19. The second fixing blocks 191 drive the second positioning rings 193 to move until the two second positioning rings 193 are in contact. Then, the pins 195 are inserted into the corresponding through holes 196 to complete the fixation of the stabilizing plates 194, so that the second positioning rings 193 can be fixed on the pipeline to be cut, enabling the connecting pipe 11 and the pipeline to be cut to be in a parallel state. At the same time, the water meter body 1 is kept stationary, avoiding shaking during marking and affecting the measurement results, and improving the accuracy of water meter installation; through the arranged first springs 192, when the pins 195 are disengaged from the through holes 196, the two first springs 192 can move their respective second fixing blocks 191 away from each other, thereby automatically opening the second positioning rings 193 for convenient use.

[0030] By adopting the above technical solution, by arranging the connecting blocks 5 and the limiting rod 51, the bolt 195 can be limited to prevent it from falling out of the stabilizing plate 194.

[0031] A clamping rod 6 is fixedly installed at one end of the second connecting rod 16 close to the first connecting rod 15, and the clamping rod 6 is movably clamped inside the first connecting rod 15.

[0032] By adopting the above technical solution, by arranging the clamping rod 6, the distance between the support plate 14 and the mounting plate 17 can be changed, facilitating adjustment according to the distance between the connecting pipe 11 and the pipeline to be cut.

[0037] Working principle: In actual use, first place the first positioning ring 12 and the second positioning ring 193 above the connecting pipe 11 and the pipe to be cut. Then move the first positioning ring 12 and the second positioning ring 193 downward so that the connecting pipe 11 and the pipe to be cut respectively enter the space between the first positioning ring 12 and the second positioning ring 193. Then install the first positioning ring 12 on the connecting pipe 11. At this time, by moving the two stabilizing plates 194, drive the second fixing block 191 to move on the guide rod 19. The second fixing block 191 drives the second positioning ring 193 to move until the two second positioning rings 193 are in contact. Then insert the pin 195 into the corresponding through hole 196 to complete the fixation of the stabilizing plate 194, so that the second positioning ring 193 can be fixed on the pipe to be cut, enabling the connecting pipe 11 and the pipe to be cut to be parallel, and at the same time keeping the water meter body 1 stationary, avoiding shaking during marking and affecting the measurement result, and improving the accuracy of water meter installation; by providing the first spring 192, when the pin 195 disengages from the through hole 196, the two first springs 192 can move their respective second fixing blocks 191 away from each other, thus automatically opening the second positioning ring 193 for convenient use; by driving the double-headed screw 2 to rotate, the two first fixing blocks 13 move closer to each other, and the two first fixing blocks 13 drive the first positioning rings 12 they are connected to move, so that the first positioning ring 12 can be fixed on the connecting pipe 11, and disassemble by reversely driving the double-headed screw 2, improving the installation efficiency.
