[0020] By adopting such a structure, the reduction motor is controlled to rotate forward and reverse, thereby driving the sliding block to move forward and backward along the H-shaped track, thereby driving the first steel wire rope to approach and move away from the second steel wire rope, thereby achieving the opening and closing effect of the flexible skylight net.

[0021] As a further improvement of the utility model, the pulley frame includes a vertical plate spaced apart from the outer side surface of the H-shaped track, and the first steel wire rope passes through the vertical plate and is fastened by a first fastener.

[0022] With such a structure, it is convenient to fasten the first steel wire rope to the pulley frame.

[0023] As a further improvement of the present invention, the second steel wire rope passes through the H-shaped track side plate and is fastened by a second fastener.

[0024] Such a structure makes it easy to fasten the second steel wire rope to the H-shaped track.

[0025] As a further improvement of the utility model, a double I-beam platform is set up on the top of the column, a lifting cylinder is set up on the double I-beam platform, a steel cable extends from the lower end of the lifting cylinder, and the steel cable is fastened to the bracket cross tube.
