A screen protecting assembly includes a pivot shaft, a curtain, two connecting bases and two rotating buttons. The curtain wraps around the pivot shaft. The connecting bases are connected to two opposite ends of the pivot shaft. Each rotating button has a first connecting portion and a second connecting portion. The first connecting portion engages the pivot shaft, and the second connecting portion is rotatably connected to the connecting base. When the rotating buttons are rotated in a first direction, the curtain unfolds to cover a screen of the electronic device. When the rotating buttons are rotated in a second direction counter the first direction, the curtain wraps around the pivot shaft again, so that the screen of the electronic device is exposed.
