The above-mentioned scheme solves the problem that the fixing device cannot be adjusted according to different sizes of the duct fan, resulting in that the existing fixing device cannot be used when the duct fan size is too small, which reduces the convenience and practicality of the use of the fixing device.

[0023] According to the present specific embodiment, the mounting seat 102 is fixedly connected to the fixing plate 101 and is located above the fixing plate 101, the bearing block 103 is fixedly connected to the mounting seat 102 and is located inside the mounting seat 102, the two groups of the fixing components are symmetrically arranged, each group of the fixing components includes a rotating disk 104, a rotating rod 105, a sliding block 106, two groups of clamping members and an adjusting member, the rotating disk 104 is fixedly connected to one end of the rotating rod 105 and is located outside the mounting seat 102, the other end of the rotating rod 105 is rotatably connected to the mounting seat 102 and is located inside the mounting seat 102, and the surface of the rotating rod 105 has a bidirectional thread, the sliding block 106 is rotatably connected to the rotating rod 105 and is located outside the rotating rod 105, and the rotating rod 10 5 penetrates the sliding block 106, and the two groups of clamping members are symmetrically arranged. The clamping members are threadedly connected to the rotating rod 105 and are located on the outside of the rotating rod 105. The adjusting member is threadedly connected to the sliding block 106 and is located below the rotating rod 105. The fixing plate 101 fixes the mounting seat 102. The duct fan is placed above the bearing block 103. The rotating disk 104 is rotated, and the rotating rod 105 drives the clamping member to move longitudinally. The rotating rod 105 rotates in the sliding block 106. The adjusting member is rotated, and the sliding block 106 pushes the clamping member to move horizontally. The rotating disk 104 cooperates with the adjusting member to make the clamping member completely fit the duct fan. This method can effectively solve the problem that the fixing device cannot be adjusted and fixed according to different sizes of duct fans.

[0024] Among them, the moving block 107 is threadedly connected to the rotating rod 105 and is located in the mounting seat 102, and the rotating rod 105 passes through the moving block 107. The fixed seat 108 is fixedly connected to the moving block 107 and is located above the moving block 107.
