第一连杆2设置有限定第一连杆2运动轨迹的第一限位部，同时，第二连杆3设置有限定第二连杆3运动轨迹的第二限位部。第一连杆2和第二连杆3在同一驱动元件的驱动下运动，并且，在各自的限位部的限位作用下沿限定的运动轨迹运动，进而，两个连杆同时带动导风板6伸出和旋转。
可选地，第一连杆2和第二连杆3在各自的限位部的限定下，先同时作直线运动，第一连杆2和第二连杆3共同带动导风板6作直线运动，使导风板6从关闭状态直线伸出第一预设位置；然后，第一连杆2在第一限位部的限定下运动改向，第二连杆3则继续作直线运动，此时，第一连杆2与第二连杆3发生相对运动，第一连杆2与第二连杆3共同带动导风板6转动。
可选地，第一预设位置为导风板6平移伸出空调器并即将开始转动的位置，此时，导风板6与出风口之间具有一定距离、且导风板6可以在第一预设位置向上或向下开启。 可选地，导风板6的旋转位置可以不限定于在第一预设位置处，第一预设位置还可以理解为导风板6作转动的初始位置，导风板6的旋转可以理解为边伸出边转动。

可选地，第一限位部包括第一限位滑块组，第一限位滑块组中的多个滑块用于共同限定第一连杆2的运动轨迹，第二限位部包括第二限位滑块组，第二限位滑块组中的多个滑块用于共同限定第二连杆3的运动轨迹。

可选地，第一限位滑块组包括第一端部滑块211和第一协作滑块212，第一端部滑块211设置于第一连杆2的端部，如图6所示。其中，导风板6伸出至第一预设位置后，第一端部滑块211的运动改向，第一协作滑块212继续作直线运动，进而使第一连杆2的运动改向。
可选地，用于限定第一端部滑块211和第一协作滑块212的轨道不同，当导风板6伸出至第一预设位置后，第一端部滑块211的轨道方向改变，使得第一端部滑块211运动改向，而第一协作滑块212继续沿原方向作直线运动，进而使得第一连杆2的运动改向。
可选地，第一端部滑块211与第一协作滑块212之间的距离大于或者等于导风板6从初始位置伸出至第一预设位置之间的第二距离。
初始位置可以理解为导风板6关闭出风口时导风板6所在的位置，也可以理解为出风口处；第一预设位置可以理解为导风板6伸出出风口，且可以在此处进行向上开启或向下开启转动的位置。第二距离为初始位置与第一预设位置之间的距离。可选地，导风板6从初始位置作直线运动移动至第一预设位置，第二距离还可以理解为导风板6所作的直线运动的直线的长度。
第一端部滑块211与第一协作滑块212之间的距离大于第二距离，有利于使第一连杆2在第一端部滑块211和第一协作滑块212共同限定下沿预设的运动轨迹运动，提高了第一端部滑块211和第一协作滑块212对第一连杆2的限位效果。
可选地，第二连杆3设置有供第一协作滑块212贯穿滑动的贯穿滑道31。
第二连杆3设置于第一连杆2与轨道板4之间，第二连杆3上贯穿滑道31的设置，使得第一连杆2的第一协作滑块212可以通过贯穿滑道31在轨道板4的轨道部的限定下运动。可选地，轨道板4上第一协作滑块212的轨道为第二轨道44，可选地，第二轨道44包括三条相互平行的直线形轨道。
可选地，第二限位滑块组包括呈三角形排布的三个滑块。
