[0054] The beneficial effect of adopting the above preferred solution is that when the rotating switch frame stopper abuts against the fixed frame stopper, it is beneficial to limit the rotating switch frame mechanism, so that the air outlet in the middle area of ​​the fixed outer frame can be opened and closed.

[0063] The beneficial effect of adopting the above preferred solution is that it is helpful to increase the friction force and facilitate the operator to rotate the rotary switch frame body.

[0064] The working process of the utility model is described below by an embodiment:

[0065] like Figures 1 to 8 As shown, in the initial state, the fixed frame mechanism 1 is installed on the column of the tractor cab, and the opening between the fixed outer frame 11 and the fixed inner frame 12 connects the cab with the air passage inside the column, and the opening in the middle of the rotary switch frame body 21 is arranged in the same direction as the opening between the fixed outer frame 11 and the fixed inner frame 12. At this time, the cold air in the air passage inside the column enters the cab through the opening in the middle of the fixed inner frame 12, the opening in the middle of the fixed outer frame 11, the opening in the middle of the rotary switch frame body 21 and the guiding effect of the air guide blade 33;

[0066] When the cold air needs to be turned off or reduced, the first rotating dial 27 is turned clockwise or counterclockwise to drive the rotary switch frame body 21 and the rotary switch frame block 22 installed on the rotary switch frame body 21 to rotate clockwise or counterclockwise. When the rotary switch frame body 21 rotates 90 degrees from the initial state, the rotary switch frame block 22 just abuts against the fixed frame block 14, and the arc-shaped side wall of the rotary switch frame body 21 just covers the opening in the middle of the fixed outer frame 11. At this time, the rotary switch frame body 21 can no longer continue to rotate in the same direction, and the cold air is turned off and cannot be blown out from the inside of the column;

[0067] To reduce the cold wind, the rotary switch frame body 21 only needs to be rotated less than 90 degrees from the initial state;

[0068] To turn on or increase the cooling air again, you only need to reverse the above steps, which will not be repeated here;

[0069] When the wind direction needs to be adjusted, the second rotating dial 32 is rotated to make the second rotating shaft 31 and the wind guide blades 33 rotate coaxially. Since the wind guide blades 33 are arranged at an angle, the coaxial rotation can realize the change of the inclination angle of the wind guide blades 33 in space, so that the wind direction can be guided in different directions.
