[0032] The top of the bottom plate 1 is provided with an adjustment mechanism 2, which includes a first motor 201 and an electric slide rail 213. The two electric slide rails 213 are fixedly mounted on the left and right sides of the top of the bottom plate 1.

By setting the corrugated hose 7, due to its own soft and elastic material, the ventilation box 5 will not be unable to move due to the limitation of the length of the corrugated hose 7 when driving the trumpet-shaped ventilation pipe 6 to move, so that when the trumpet-shaped ventilation pipe 6 ventilates different areas, the air can be transmitted to the outside through the corrugated hose 7. By setting the anchor bolts 11, the overall stability of the equipment can be provided to avoid the equipment from tipping over due to external collisions, thereby causing damage to the overall components of the equipment.

Through the cooperation of the electric slide rail 213 and the electric slider 214, the electric slider 214 moves back and forth along the surface of the electric slide rail 213. At this time, the electric slider 214 drives the mounting plate 3, the support frame 4, and the parts on the top of the support frame 4 to move back and forth synchronously with the ventilation box 5 and the trumpet-shaped ventilation pipe 6, thereby completing the adjustment of the overall position of the ventilation box 5 and the trumpet-shaped ventilation pipe 6 and expanding the ventilation range of the trumpet-shaped ventilation pipe 6.
