In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] The existing flue installation construction tools are used to connect the flue with the pipe of the range hood so that the oil smoke in the range hood can be discharged into the flue. Most of the existing installation construction tools are fixed on the pipe and the fixing parts using a ferrule during installation. The ferrule is easy to cause damage to the pipe and the fixing parts when tightened, and the ferrule is easy to loosen under the erosion of oil smoke, thereby causing the problem of oil smoke leakage. Therefore, a sealing mechanism is required when using a flue installation construction tool to facilitate sealing installation;

[0005] Therefore, a flue installation construction tool is proposed to address the above problems. Utility Model Content
