[0009] Preferably, one end of the screw is fixedly connected to a connecting column, and the end of the connecting column away from the screw passes through the mounting frame and is fixed with a rotating plate, and the rotating plate is arranged in the bracket. Through the arrangement of the rotating plate and the connecting column, the user can control the rotation of the screw outside the device.

[0010] Preferably, mounting plates are fixed at both ends of the outer wall of the mounting frame, and multiple mounting holes are opened in the two mounting plates. A handle is fixed at one end of the protective ventilation plate outside the bracket. Through the arrangement of the mounting plates and the mounting holes, the device can be installed as a whole.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In the utility model, the rotation of the screw and the cooperation of the limit column can drive the connecting plate and the support plate to move, thereby driving the motor and the fan installed at one end of the support plate to move, so that they can be moved out of the ventilation duct, which is convenient for their maintenance and replacement. There is no need for manual entry into the ventilation duct to repair the motor and the fan, which is safer. By setting up the protective ventilation plate, on the one hand, the air intake port of the device can be blocked to prevent too much wind from causing people or large debris to enter the ventilation duct and damage the fan, which is safer.
