[0003] The patent with announcement number CN216715425U discloses a water supply, drainage and HVAC positioning and installation mechanism. The patent fixes the position of the pipeline by setting a convenient clamping structure, and can fix pipelines of different sizes; uses a convenient adjustment mechanism to adjust the position of the adjustment plate to reduce the limitations of the use position after the device is fixed; and can adjust and fix the position of the connecting plate through a convenient installation and fixing mechanism.

[0004] However, the patent has the following defects: on the one hand, the size of HVAC pipes usually adopts the national standard size, and the diameters of common HVAC pipes are 20mm, 25mm, 32mm and 40mm, etc. The use of a portable clamping structure with a variable diameter is relatively costly, and the contact area with the outer side of the water supply and drainage HVAC pipe is small, and the clamping effect is poor; on the other hand, the portable adjustment structure cannot always ensure that the worm wheel and the worm are engaged, and the production and assembly process of the worm wheel and the worm is relatively complicated; on the other hand, under normal circumstances, after the mounting plate is fixed, the position between the portable clamping structure and the adjustment plate only needs to be slightly adjusted, and no large range adjustment is required. However, the convenient installation and fixing structure in this scheme, due to the connection relationship between the first fixing screw and the first fixing hole for assembly, cannot achieve continuous adjustment of the installation position of the connecting plate, the adjustment interval is large, and the operability is not strong.
