你所問的是三角形架的支點、力點、重點和窗外懸掛問邊緣題？１）重點是近牆壁的邊緣低底部２）力點是抓緊冷氣機的散熱器邊緣３）支點是牆壁的冷氣機頂端外邊緣懸掛；窗外邊緣懸掛是抓緊冷氣機的入風口．
已上資料只屬參考．，﹝如有類同，實屬巧合．﹞
What you asked is a triangle pivot, the point of force, key andoutside the window is hanging asks the edge topic? 1) the key point isthe near wall edge low base 2) the point of force is grasps the airconditioner the radiator edge 3) the pivot is outside the wall airconditioner peak the edge is hanging; Outside the window the edge is hanging is grasps the air conditioner to enter the gusty area.
