Patented winding protection device:

The ordinary winding device will continue to rotate the transmission device after the rolling shutter is placed in position, which will roll up the fabric in the opposite direction, so that the winding will not change or even damage the product. This device is specially designed. After the sunshade fabric is unfolded in place, the rotating power will not be transmitted to the winding shaft when the winding continues, so as to prevent the fabric from being folded in the direction, avoid trouble and protect the product.
