The second transmission member 14 has a second central transmission part 141 and a second side transmission part 142. The second central transmission part 141 can be mutually transmitted with the second side transmission part 142. The rope winding part 20 has a base 21. A first rope winding shaft 22 and a second rope winding shaft 23 are pivotally arranged parallel to each other on the base 21. The first rope winding shaft 22 and the second rope winding shaft 23 can respectively wind a top rope winding 24 and a bottom rope winding 25. The main transmission shaft 12 is combined with the first central transmission part 131. The first side transmission part 132 of the first transmission member 13 on the right side is combined with a top transmission shaft 15. The top transmission shaft 15 is coaxially combined with the first rope winding shaft 22 of the rope winding part 20 on the same side and is combined with the second side transmission part 132 of the second transmission member 14 on the left side. 142 combination and the first rope winding shaft 22 of the rope winding part 20 are coaxially combined, the first side transmission part 132 of the first transmission member 13 located on the left side is combined with a bottom transmission shaft 16, the bottom transmission shaft 16 is coaxially combined with the second rope winding shaft 23 of the rope winding part 20 on the same side and is coaxially combined with the second side transmission part 142 of the second transmission member 14 located on the right side and the second rope winding shaft 23 of the rope winding part 20, the second central transmission part 141 of the second transmission member 14 and the synchronizer 30 are both combined with a synchronization transmission shaft 17.

When the first synchronization rod 31 hits the second synchronization rod 32, the top transmission shaft 15 cannot be rolled further, thereby limiting the minimum distance between the top and the bottom of the honeycomb curtain 40. When the second synchronization rod 32 is screwed back, it hits the first synchronization rod 31 and screws the first synchronization rod 31 back together, thereby lifting the honeycomb curtain 40 while limiting the minimum distance between the top and the bottom of the honeycomb curtain 40.
