At this time, the first threaded hole 4 on the upper connecting plate 3 is aligned with the first threaded hole 4 on the upper mounting groove 2. The first fixing screw 5 is screwed into the first threaded hole 4 to fix the upper connecting plate 3 on the duct main body. The inner top of the body 1 can be operated by installing the first fixing screw 5 on the outside of the air duct body 1. A lower mounting groove 6 is provided at the bottom of the air duct body 1, and a lower connecting plate 7 is fitted on the upper surface of the lower mounting groove 6. Second threaded holes 8 are provided at both ends of the lower connecting plate 7 and the lower mounting groove 6, and a second fixing screw 9 is penetrated inside the second threaded hole 8. The inner side of the lower connecting plate 7 is slidably fitted with the lower mounting groove 6, and the lower connecting plate 7 is fixed to the inner bottom of the air duct body 1 by the second fixing screw 9. The installation method of the lower connecting plate 7 is the same as that of the upper connecting plate 3. Similarly, the lower connecting plate 7 can be installed on the inner bottom of the air duct body 1. This fixing method is simple, practical, easy to operate, and removable. Two upper connecting plates 3 and lower connecting plates 7 are provided, and the upper connecting plates 3 and lower connecting plates 7 are parallel to each other. The air duct body 1 can be effectively reinforced by setting two groups of upper connecting plates 3 and lower connecting plates 7.

[0022] The column mechanism 10 is arranged between the upper connecting plate 3 and the lower connecting plate 7.
