[0025] The clamping rod 4 passes through the sliding grooves 10 on both sides of the U-shaped tube bundle 12 and slides inside the sliding grooves 10 on both sides of the U-shaped tube bundle 12. The clamping rod 4 drives the clamping block 6 to move inside the U-shaped tube bundle 12. The connecting screw 8 at the bottom of the clamping rod 4 is inserted into the outer fixing seat 5 on both sides of the U-shaped tube bundle 12. The fixing nut 11 is sleeved on the outside of the connecting screw 8 and contacts the bottom of the outer fixing seat 5. The second fixing block 14 outside the fixing nut 11 is aligned with the first fixing block 13 outside the outer fixing seat 5. The loosening insertion rod 15 passes through the interior of the first fixing block 13 and the second fixing block 14.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, by setting a clamping anti-loosening structure, during use, the U-shaped tube bundle 12 and the clamping rod 4 are placed above and below the fire-fighting pipe, allowing the connecting screws 8 on both sides of the bottom of the clamping rod 4 to extend and retract inside the outer fixing seat 5, driving the clamping rod 4 to move inside the sliding grooves 10 on both sides of the U-shaped tube bundle 12, so that the clamping block 6 outside the clamping rod 4 clamps the fire-fighting pipe inside the U-shaped tube bundle 12. Then, the fixing nut 11 is threaded onto the outside of the connecting screw 8 and contacts the bottom of the outer fixing seat 5, so that the second fixing block 14 outside the fixing nut 11 is aligned with the first fixing block 13 outside the outer fixing seat 5. Then, the loosening insert 15 is inserted into the inside of the first fixing block 13 and the second fixing block 14 to prevent the fixing nut 11 from loosening outside the connecting screw 8, thereby realizing the clamping anti-loosening function.

[0027] The rear end of the sliding groove 10 is provided with a side disassembly groove 16, and the rear end of the outer fixed seat 5 is provided with a rear moving groove 18, and a limit block 17 is installed inside the rear moving groove 18.

[0028] The clamping rod 4 enters the sliding groove 10 through the side disassembly groove 16. The connecting screw 8 at the bottom of the clamping rod 4 is engaged with the interior of the outer fixing seat 5 through the rear moving groove 18 at the rear end of the outer fixing seat 5. The inner wall of the rear moving groove 18 is provided with a limit block 17.

[0029] Specifically, such as Figure 2 and Figure 4 As shown, by setting an easy-to-disassemble structure, the rubber sleeve 7 can be detached from the outside of the U-shaped tube bundle 12 during use, allowing the clamping rod 4 to move inside the sliding groove 10 carrying the connecting screw 8. Then, the clamping rod 4 can be removed from the side disassembly groove 16 at the rear end of the sliding groove 10, and at the same time, the connecting screw 8 can be pulled out from the rear moving groove 18 at the rear end of the outer fixing seat 5, allowing the rear moving groove 18 to separate from the outer fixing seat 5 through the limit block 17, thereby realizing the easy-to-disassemble function.

Next, the rubber sleeve 7 is snapped onto the outside of the U-shaped pipe bundle 12. Then, the connecting screws 8 on both sides of the bottom of the clamping rod 4 extend and retract inside the outer fixing seat 5, causing the clamping rod 4 to move within the sliding grooves 10 on both sides of the U-shaped pipe bundle 12. This allows the clamping block 6 outside the clamping rod 4 to clamp the fire-fighting pipe inside the U-shaped pipe bundle 12. Finally, the fixing nut 11 is threaded onto the outside of the connecting screw 8 and contacts the bottom of the outer fixing seat 5, allowing the fixing screw... Align the second fixing block 14 on the outside of the mother 11 with the first fixing block 13 on the outside of the outer fixing seat 5. Then, insert the loosening rod 15 into the inside of the first fixing block 13 and the second fixing block 14 to prevent the fixing nut 11 from loosening outside the connecting screw 8. Then, the connecting ear block 9 at the top of the U-shaped tube bundle 12 rotates with the upper hanging seat 1 through the rotating shaft 3 to adjust the position of the upper mounting seat 2 at the top of the upper hanging seat 1. Then, connect the connecting rod with the rear connecting sleeve 21 inside the upper mounting seat 2 as needed. Then, rotate the rear connecting sleeve 21 inside the upper mounting seat 2 through the flip shaft 20 as needed. After adjusting the rotation position of the rear connecting sleeve 21, rotate the locking knob 19 at the front end of the upper mounting seat 2 to limit the rear connecting sleeve 21 inside the upper mounting seat 2.
