[0051] The working principle and use process of this utility model:

[0052] When installing the fresh air fan, the operator first rotates the nut 23 to make the nut 23 disengage from the contact with the threaded rod 21, thereby releasing the fixation of the mounting plate 22, allowing the operator to remove the mounting plate 22 from the outer surface of the threaded rod 21, and thus installing the fresh air fan. The operator can start the motor 25 according to the different sizes of the fresh air fan, so that the circular shaft 26 drives the rotating plate 27 to rotate, and then the hinged plate 28 can pull the two movable rods 19 along the inner surface of the slide groove 18 to move toward each other, thereby changing the distance between the two movable rods 19, and then installing fresh air fans of different sizes.

[0053] When the operator needs to adjust the direction of the installed fresh air fan, he can pull the pull plate 14 downward so that the pull plate 14 drives the plug 15 to move downward, thereby releasing the fixing effect on the slider 9. At this time, the operator pushes the handle 10 so that the handle 10 drives the slider 9 to move along the outer surface of the connecting plate 7, thereby enabling the rectangular frame 11 to move, so that the rectangular frame 11 squeezes and pushes the outer surface of the round rod 5, so that the round rod 5 drives the movable sleeve 4 to rotate with the circular plate 3 as the axis, thereby adjusting the direction of the fresh air fan, which is convenient for the operator to use.
