The connecting rod assembly is limited by the bracket assembly and the actuator. The other end of the connecting rod assembly is connected to the damper baffle assembly. The connecting rod assembly is driven by the actuator to open and close the damper baffle.

[0025] In this embodiment, it is further configured that the actuator includes a housing 11, a handwheel 12, a wiring assembly 13, a drive assembly, a transmission assembly, an operating assembly 14 and a mounting base 15. An installation space is provided inside the housing, the handwheel is installed on the top of the housing, the wiring assembly is installed on the bottom of the housing, the drive assembly and the transmission assembly are both installed inside the housing, the drive assembly and the transmission assembly are not drawn in the figure, the output end of the drive assembly is connected to the transmission assembly, the operating assembly is installed on the side away from the bracket assembly, and the mounting base is installed on the side close to the bracket assembly.

[0026] In this embodiment, the bracket assembly includes a base plate 21, risers 22, and reinforcements 23. One edge of the base plate's top surface is connected to the bottom of the risers, the bottom surface of the reinforcements is connected to the top surface of the base plate, and the vertical surface of the reinforcements is connected to the vertical surface of the risers. The base plate, risers, and reinforcements can be integrally formed or welded together. Integral formation is preferred, as it provides greater structural strength.
