The duct fixture includes a fixing seat having a through hole, a fixing disk, a limiting block disposed on a side of the fixing disk adjacent to a target mounting surface, and a positioning protrusion disposed on the fixing disk, an outer shape of the limiting block matches a mounting hole on the target mounting surface, a limiting groove for receiving the target mounting surface is formed between the limiting block and the fixing disk, and the positioning protrusion is disposed angularly with the limiting block around the central axis of the through hole. When the limiting block rotates to a staggered position relative to the mounting hole, the positioning protrusion enters the mounting hole.
