The implementation principle of the embodiment is as follows: when the device is used at ordinary times, the sliding block 33 is driven to move by the electric pushing cylinder 3, and the sliding block 33 moves to drive the first guide wheel 24 and the second guide wheel 26 to move. When the sliding block 33 descends, the first traction rope 25 is tightened by the first guide wheel 24, and at the moment, the bottom sheet 23 ascends to support the upper louver blades 21, so that all the louver blades 21 are driven to ascend; when the slide block 33 is raised, the second traction rope 27 is tightened by the second guide pulley 26, and the bottom piece 23 is lowered downward. When the bottom plate 23 is lowered, the bottom plate 23 is connected to the connecting cord 22, and the lowermost louver 21 is thereby lowered. Because the two adjacent louver blades 21 are connected through the linkage rod 45 and the linkage groove 44 which are hinged on the linkage edge 4, and the linkage piece at one end of the linkage rod 45 far away from the linkage edge 4 slides along the linkage groove 44 in the upper adjacent louver blade 21, the whole louver blades 21 form a linkage mechanism which can be opened or closed together, and the louver blades 21 can be closed conveniently under the drive of the bottom sheet 23. When all the louvers 21 are closed, it is natural that the bottom end of the louver assembly 2 can be well attached to the bottom end of the outer frame 1. And through being provided with spacing clamping jaw 6, when electronic push cylinder 3 drove bottom piece 23 and descend to the position with spacing clamping jaw 6 upper surface butt, because last spacing claw 61 is rotatable, go up spacing claw 61 and keep away from the distance between the axis of rotation's the one end and the axis of rotation in the horizontal plane of axis of rotation and can be shorter and shorter, when bottom piece 23 overcome last spacing torsional spring, make bottom piece 23 slide to in last spacing claw 61 and the lower spacing claw 62, bottom piece 23 continues to move down and collides lower spacing claw 62. When the lower limiting claw 62 is abutted by the bottom piece 23, the lower limiting claw 62 rotates around the rotation axis to enable the other end of the lower limiting claw 62 to ascend, and enable the upper control block 611 at the other end of the lower limiting claw 62 to trigger the upper proximity switch 65, when the upper proximity switch 65 responds, the direct current servo motor 54 rotates and drives the limiting rod 51 to descend by the length of one limiting track 5, so that the whole limiting clamping jaw 6 descends, the upper limiting claw 61 is abutted with the bottom piece 23 and drives the bottom piece 23 to descend, and the bottom piece 23 can be well pulled to the bottom of the outer frame 1 through the limiting clamping jaw 6. At the moment, light can be well shielded, and the light is not easy to irradiate into a room from a gap between the louver assembly 2 and the bottom end of the outer frame 1. When the bottom plate 23 needs to be lifted, because the bottom plate 23 is still located in the limiting clamping jaw 6, the bottom plate 23 is lifted and abutted to the upper limiting jaw 61, the upper limiting jaw 61 rotates around the rotating axis, one end of the upper limiting jaw 61, which is far away from the bottom plate 23, descends, the lower control block 621 on the other end of the upper limiting jaw 61 triggers the lower approach switch 66, and when the approach switch responds, the direct-current servo motor 54 rotates and drives the limiting rod 51 to ascend by the length of one limiting rail 5, so that the whole limiting clamping jaw 6 is lifted, and the bottom plate 23 is lifted. When the bottom piece 23 rises to the upper end of the stopper rail 5, the bottom piece 23 is pulled by the first traction rope 25 and finally overcomes the upper stopper torsion spring between the upper stopper 61 and the lower stopper 64, and then the bottom piece 23 is separated from between the upper stopper 61 and the lower stopper 62.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
