     As indicated schematically, a vehicle may an air conditioning system for heating or cooling air and supplying the heated or cooled air to the interior space of the vehicle compartment through an air outlet structure. See  FIGS. 1A-1D . 
       FIG. 16  shows a conventional outlet structure comprising a housing  1   x , a horizontal blade assembly  2   x , a perpendicular blade  3   x  and an air door  4   x ; the horizontal blade assembly  2   x  may be installed at the front end of the housing  1   x  by a panel  11   x , the perpendicular blade  3   x  may be installed at the middle of the housing  1   x  by a support  12   x ; and the air door  4   x  may be installed at the rear end of the housing  1   x .

Since the perpendicular blade  3   x  is driven by the leftward and rightward toggling of the toggle button  5   x , the results in a need for a large arrangement space, which is not applicable to a spatially limited environment. As indicated schematically, since the toggle button  5   x  is installed on one blade in the middle of the horizontal blade assembly  2   x , the structure occupies a certain space and can shield the air blowing and influence the air blowing effect. As shown schematically in  FIG. 16 , since the air outlet is narrow, the air outlet structure may comprise a follow-up blade  6   x  installed on a hidden blade to optimize the air guiding effect. In order to arrange the follow-up blade  6   x , the front end of the perpendicular blade  3   x  needs to be partially cut away, thus affecting the air guidance of the perpendicular blade  3   x . In order to avoid cutting away a large part of the perpendicular blade  3   x , it is usually necessary to move the perpendicular blade  3   x  back in the entirety, which requires an increase in the space of the housing and causes inapplicability for spatially limited environment.
