The second embodiment of the present invention comprises two sets of blade interlocking devices, each of which comprises a plurality of blades respectively combined with a lower part of the middle section and a connecting member of the right angle structure, and the connecting piece which is bent at a right angle of the linking member is pivotally connected to the connecting hole a pivot hole that is equidistantly disposed on a connecting rod, the lower surface of each end of each blade is combined with the swinging member of the straight-angle structure, and the pivoting piece bent at right angles of the two end swinging parts is provided with a pivot hole; a larger window frame, The two horizontal frames that are twice as long as the blades are combined with the two side frames to form a larger rectangular frame. The two vertical frames provide pivotal pivoting of the pivoting members at both ends of the blade, and the two horizontal frames are opposite. A middle frame is provided for pivotally connecting the opposite ends of the two sides of the blade; the plurality of overlapping pieces are overlapped and joined at opposite ends of the left and right opposite blades, and the left and right sets of longitudinally linked blade devices can be synchronously spread. Linked blinds.

According to the above, the lap piece forms an avoidance bend portion with respect to the middle frame at the middle portion.

In view of the above, the length of the connecting rod can be designed such that when the blade is opened at ninety degrees, the lower end of the connecting rod is blocked from the top end to the lower side frame; and the inner side of the connecting rod is concave on each of the pivot holes.
