[0021] Embodiment 1

[0022] As Figures 1-3 shown, in this embodiment, an electric window screen opener is provided, including a housing. A lead screw 3 is rotatably arranged in the housing, and a motor 1 is arranged in the housing. The motor 1 is connected to the lead screw 3 through a first transmission mechanism. A nut 6 is sleeved on the lead screw 3.

[0023] A chain box 5 is arranged in the housing. A chain is slidably arranged in the chain box 5. The chain passes through the chain box 5 and the housing and is connected to the window. A strip hole is opened on the chain box 5. The nut 6 passes through the strip hole and is connected to the chain.

[0024] A fixed block 8 is arranged in the housing. The lead screw 3 passes through the fixed block 8. A compression spring 7 is connected to the fixed block 8. An annular groove is opened on the lead screw 3. When the nut 6 moves to the annular groove, it contacts the compression spring 7.

[0025] Two window screen lead screws 10 are rotatably arranged on the housing. The two window screen lead screws 10 simultaneously pass through a window screen slider 12 and are threadedly connected to the window screen slider 12.
