[0002] HVAC ducts are an indispensable part of heating, ventilation and air-conditioning systems. They include various types such as metal and non-metal. Through reasonable layout and installation, they transport heat media, air, etc. to achieve functions such as heating, ventilation, and regulating indoor temperature and humidity. They need to be regularly inspected, cleaned and maintained to ensure their normal operation.

[0003] The traditional HVAC pipe laying method mainly relies on manual operation. When fixing and installing the HVAC pipes, a support frame is required to support the metal HVAC pipes to facilitate the fixation or welding of the HVAC pipes. However, due to the different heights of buildings, the height of the support frame is not easy to adjust in different installation environments, resulting in reduced work efficiency. For this reason, a HVAC pipe laying auxiliary device is designed. Utility Model Content
