[0023] Please see Figure 1-4 This utility model provides a technical solution for a venetian blind control device, including an upper U-shaped support base 1. A double-coordinated transmission assembly 3 is installed inside the upper U-shaped support base 1. A forward and reverse drive motor 4, connected to the double-coordinated transmission assembly 3, is installed on the outer wall of the upper U-shaped support base 1. After the upper U-shaped support base 1 is installed in the wall, the double-coordinated transmission assembly 3 is driven by the forward and reverse drive motor 4. The double-coordinated transmission assembly 3 can achieve double-coordinated transmission function for the opening and closing of the venetian blinds, and has stronger overall stability. A lower support base plate 5 is provided below the upper U-shaped support base 1. Several louvered slats 6 are provided between the lower support base plate 5 and the upper U-shaped support seat 1. The two output ends of the double-coordinated transmission component 3 are connected to bidirectional pull ropes 7 that cooperate with the louvered slats 6. A limit component 8 is provided through the lower support base plate 5 and the upper U-shaped support seat 1 at the center of the louvered slats 6. Several louvered slats 6 are provided between the upper U-shaped support seat 1 and the lower support base plate 5.
