In actual use, the connecting pipe 11 and the pipeline to be installed with it are kept parallel, and the first belt 17 and the second belt 171 on the outer side are driven to rotate by rotating the driving rod 15, and the first belt 17 and the second belt 171 drive the double-headed screws 16 connected to them to rotate, and the two double-headed screws 16 jointly drive the two fixing plates 18 on the outer side to move towards each other until they are fixed to the pipeline to be connected, thereby being able to support the flow meter body 1 and facilitating the subsequent installation of it by the staff.

[0021] A fixing block 2 is fixedly installed on one side of the inner wall of the fixing bracket 13, and a clamping ring 21 is fixedly installed on the end of the fixing block 2 away from the inner wall of the fixing bracket 13.

[0022] By adopting the above technical solution, the clamping ring 21 is clamped on the outside of the connecting pipe 11, and then the two threaded rods 22 are rotated so that the two threaded rods 22 drive the pressing plates 23 to move toward each other, so that the clamping ring 21 can be pressed and fixed on the connecting pipe 11, thereby fixing the fixing bracket 13. When disassembly is required, the reverse operation can be performed, and the fixing bracket 13 can be removed after the installation of the flow meter body 1 is completed, so that it can be recycled and cost saved.

The first belt 17 and the second belt 171 drive the double-headed screws 16 connected to them to rotate, and the two double-headed screws 16 jointly drive the two outer fixing plates 18 to move toward each other until they are fixed to the pipe to be connected, so that the flow meter body 1 can be supported, which is convenient for subsequent staff to install it; by clamping the clamping ring 21 on the outer side of the connecting pipe 11, and then rotating the two threaded rods 22, the two threaded rods 22 drive the pressing plates 23 to move toward each other, so that the clamping ring 21 can be pressed so that it can be fixed on the connecting pipe 11, thereby fixing the fixing bracket 13. When disassembly is required, the reverse operation can be performed, and the fixing bracket 13 can be removed after the installation of the flow meter body 1 is completed, so that it can be recycled and cost-saving.
