<p>A venetian blind of adjustable width includes a top frame (10), a bottom frame (20), multiple slats (30), a lifting/lowering pull cord (40), a slat rotating device (50) and a rotating rod (60). The top frame (10) includes a main rail (11) and left and right rails (12, 13) which are formed by multiple mortise and tenon blocks (16, 17) which are interfitted to one another. The number of the blocks (16, 17) can be increased or reduced to adjust the width of the blind. The slat rotating device (50) is secured in the main rail. The bottom frame (20) includes a main rod (21) and left and right rods (22,23) which are also extensible and retractable relative to the main rod to adjust the length of the bottom frame to match the top frame so that the width of the blind can be adjusted according to requirements. <IMAGE></p> |
