[0002] The air duct is a pipe system for air transportation and distribution. The air conditioning duct system uses the cold and heat generated by the air conditioning main unit to centrally process the return air (or the mixture of return air and fresh air) from the room, such as cooling, heating, humidification, dehumidification, purification, etc., and then send it into the room; the existing announcement number CN 220446410 U is a kind of air duct maintenance bracket for central air conditioning, which drives the screw to rotate inside the limit groove by setting a hand wheel on the side of the support seat, so that the sliders at both ends of the limit groove adjust the spacing inside the limit groove, so that the clamping plate fixedly connected to the upper part of the slider clamps and fixes the two sides of the air duct, avoiding the phenomenon that the air duct slips on the support seat, and by rotating the fastening screw, the suction cup at one end of the inner side of the fastening screw clamps the outer surface of the air duct, further improving the fixing effect of the air duct; however, when the above bracket is used, it is necessary to first contact the support seat with the air duct and then move the clamping plate again to fix the air duct, which increases the operation steps and causes inconvenience in the use process.
