[0020] Further Figure 1 and Figure 2As shown, it is worth specifically explaining that a driving motor 7 is fixedly connected to the left side of the inner surface of the rolling shutter cover 1, and a reel 5 is fixedly connected to the output end of the driving motor 7. A plurality of anti-stuck components 13 in a rectangular array are arranged on both sides of the inner surface of the guide rail 2 and both sides of the bottom end of the inner surface of the rolling shutter cover 1. The driving motor 7 is started by the driving motor 7 so that its output end drives the reel 5 to rotate, thereby causing the reel 5 to drive the sheath 6 and the connecting rod 8 to rotate, thereby causing the reel 5 to drive the curtain piece 3 to slide and contract in the sliding groove 14, so that the connecting ring 9 provided on the connecting rod 8 can provide buffer protection between the rolling shutter cover 1 and the curtain piece 3 under the action of the spring 10, thereby indirectly extending the service life of the device.
