Since the center of the two side walls of the inner cavity of the socket are provided with sliding grooves 34, and the lower positions of the two side surfaces of the sliding rod 31 are provided, the sliding grooves 35 can slide in the inner cavity of the sliding grooves 34, and then the sliding rod 31 can slide in the inner cavity of the socket, so as to prevent the sliding rod 31 from falling off from the inner cavity of the socket.

[0039] The return frame 41 in the connecting component 4 can be fixedly connected to one end of the rectangular air duct 1 and provide a foundation for opening the installation groove 42. Since the inner cavity of the installation groove 42 is fixedly connected with a sealing gasket 43, the friction between the return frame 41 and other rectangular air ducts can be increased, thereby preventing other rectangular air ducts from falling. Since the four side surfaces of the return frame 41 are rotatably connected with fixing bolts 44 near the center position of the opening end, the fixing bolts 44 can fix and limit other rectangular air ducts, thereby improving the connection stability of other rectangular air ducts.
