The rotating connecting rod 105 is rotationally connected to the shell of the air duct main body 100 through a rotating shaft body 106. On the upper and lower end faces of the outer walls at both ends of the air duct main body 100, there are external rotating rod bodies 200. The external rotating rod bodies 200 are threadedly connected to the rotating shaft body 106 through threaded connecting rods 201. And the lower end face of the threaded connecting rod 201 penetrates and extends into the inside of the rotating shaft body 106. On the outer wall at one end of the external rotating rod body 200, there is a handshake block 202. And the handshake block 202 is rotationally connected to one end of the external rotating rod body 200.

Then, the staff drives the external rotating rod body 200 by rotating the handshake block 202. The external rotating rod body 200 drives the rotating connecting rod 105 to rotate through the rotating shaft body 106, so that one end of the rotating connecting rod 105 can extend and rotate into the inside of the third embedded cavity 10301, and finally align the connecting flange plates 101 on the outer walls of several air duct main bodies 100.

[0026] Embodiment 2
