The invention provides a roller shutter door internally-pushing device. The roller shutter door internally-pushing device is characterized in that the roller shutter door internally-pushing device is a pushing-lifting block matched with a plate of a roller shutter door, a magnet is arranged on the right side face of the pushing-lifting block, and a handle is arranged on the left side face of the pushing-lifting block. Specifically, the pushing-lifting block is rectangular. The roller shutter door internally-pushing device has the advantages of being simple in structure and convenient to use and bringing convenience to a person having small hand strength when the roller shutter door is just lifted.
