[0002] Because civil air defense projects are generally enclosed underground spaces with poor air flow, various construction or decoration materials will emit some harmful gases. For example, some plastics or paint materials will emit formaldehyde, and some reinforced concrete materials will emit radon gas. There will be various pollutants or bacteria in the air, even including excessive carbon dioxide. Therefore, when constructing civil air defense projects, the design of the ventilation system of the civil air defense projects is very important.

[0003] When installing multiple ventilation ducts in a ventilation system, the multiple ventilation ducts need to be arranged in sequence according to the installation path, and then the ventilation ducts are installed on the indoor roof in sequence using fasteners. When installing the multiple ventilation ducts, it is impossible to ensure that the installation heights of adjacent ventilation ducts remain consistent. Therefore, it is difficult to connect two adjacent ventilation ducts, which increases the installation difficulty for workers and reduces installation efficiency. Summary of the invention

[0013] A bidirectional screw, the bidirectional screw being rotatably installed in the slide slot along a first direction, and one end of the bidirectional screw extending out of the slide slot and connected to a rotating handle;

[0014] Among them, the bidirectional screw has two thread segments, the thread directions of the two thread segments are set in opposite directions and distributed along the first direction, and the two sliders are respectively threadedly sleeved on the outside of the two thread segments. When the bidirectional screw rotates, the two sliders slide towards or away from each other to make the ventilation duct rise and fall.

[0015] As a further improvement and optimization of this solution, the first direction is consistent with the width direction of the ventilation duct.

[0016] As a further improvement and optimization of this solution, each of the mounting structures further includes:
