In the above structure, there are two fixed blocks 4, pressure plates 6 and pressure columns 9, which are clamped with the notches on the inner wall of the support block 1 through two fixed blocks 4, so that the clamping is more firm.

[0022] In a preferred embodiment, the inner wall of the support block 1 is provided with a plurality of slots, and the size of the slots is adapted to the size of the fixed block 4. In the above structure, by snapping the fixed block 4 into the target slot, the fixed block 4 fixes the extension block 3 inside the support block 1, thereby fixing the detection body 2.

[0023] In a preferred embodiment, the pressure column 9 penetrates the outer wall of the extension block 3, and the pressure column 9 is slidably connected to the extension block 3, and the end of the pressure column 9 away from the pressure plate 6 and the end of the fixed block 4 away from the fixed block 4 are in the same plane. In the above structure, by pressing the pressure column 9, the pressure column 9 moves toward the inner wall of the extension block 3, and then drives the pressure plate 6 to move toward the inner wall of the extension block 3. After the fixed block 4 is pulled toward the inner wall of the extension block 3 by the pressure plate 6, when the pressure column 9 completely enters the inner wall of the extension block 3, the fixed block 4 completely enters the inner wall of the extension block 3.

[0024] In a preferred embodiment, the guide rail 7 and the limiting column 8 penetrate the pressure plate 6, and an extension piece is provided in the middle of the guide rail 7. In the above structure, the pressure plate 6 is penetrated by the guide rail 7 and the limiting column 8, so that the guide rail 7 and the limiting column 8 limit the pressure plate 6, thereby preventing the pressure plate 6 from tilting due to the position of the center of gravity being pressed.

[0025] In a preferred embodiment, the size of the locking block 14 is adapted to the size of the fixing groove 15, and the locking block 14 is located above the fixing groove 15. In the above structure, by placing the locking block 14 into the inner wall of the fixing groove 15, the fixing groove 15 cannot move, and the fixing groove 15 is fixed by the locking block 14, and the fixing belt 5 is fixed by the fixing groove 15.

[0026] In a preferred embodiment, there are several fixing grooves 15, and the several fixing grooves 15 are evenly distributed on the outer wall of the fixing belt 5. In the above structure, the locking block 14 is engaged with different fixing grooves 15, so that the length of the fixing belt 5 is changed through the extension block 3, thereby making the length of the fixing belt 5 adjustable so that it can adapt to different usage environments.

[0027] Working principle: when installing the device, by pressing the two pressure columns 9, the two pressure columns 9 drive the two pressure plates 6 to move inside the extension block 3, and the two pressure plates 6 pull the two fixed blocks 4 to move inside the extension block 3, so that the fixed block 4 is disengaged from the circular groove on the inner wall of the support block 1, so that the extension block 3 can slide on the inner wall of the support block 1, and the distance between the two extension blocks 3 is adjusted by moving the two extension blocks 3, so as to adjust the distance between the two detection bodies 2. When the adjustment is completed, the pressure column 9 is released, and the structure is reset by the rebound force of the spring 10, so that the fixed block 4 is re-engaged with the notch on the inner wall of the support block 1, so as to fix the two detection bodies 2. At this time, the bottom of the detection body 2 is fitted with the outer wall of the pipeline, and the fixing belt 5 is passed through At the bottom of the pipeline, it is placed in the inner wall of the extension block 3 after being wrapped around once. At this time, the pull rod 11 is pulled upward, so that the pull rod 11 drives the pressure plate 13 and the locking block 14 to move upward, thereby causing the spring 2 12 to contract. At this time, the fixing belt 5 is passed through the extension block 3 to reach the other side of the extension block 3, thereby causing the fixing groove 15 to move toward the inside of the extension block 3. When the fixing belt 5 is fully tightened, due to the different sizes of the pipelines, when the target fixing groove 15 reaches the bottom of the locking block 14, the pull rod 11 is released, and the locking block 14 is pushed downward by the rebound of the spring 2 12 to enter the inside of the fixing groove 15, thereby fixing the fixing groove 15 and then fixing the fixing belt 5, so that the detection body 2 is fixed on the outer wall of the pipeline, and the flow rate is monitored through the two detection bodies 2.
