Figure 4As shown, a plurality of blades 1 are arranged in parallel and sequentially arranged, and sequentially connected through the connecting part 2 and the connecting groove 3 to form a complete roller shutter structure. The number and length of the blades 1 can be adjusted according to actual needs. The blade 1 as a whole can be a rectangular plate structure, and the first side wall and the second side wall are two side walls in the length direction of the blade 1, that is, the side wall adjacent to each blade 1 and the adjacent blade 1. The blade 1 can be made of high-strength and weather-resistant materials such as aluminum alloy or engineering plastic to withstand the effects of wind, rain, ultraviolet rays and other factors in outdoor environments.
[0040] The connecting part 2 is arranged on the first side wall, and the connecting part 2 can be a protruding structure arranged on the first side wall, which can be inserted into the connecting groove 3 and will not come out of the connecting groove 3, so as to ensure the stability of the connection and the flexibility of the rotation.
[0041] The connecting groove 3 is arranged on the second side wall, and the shape of the connecting groove 3 is complementary to the connecting part 2. The connecting groove 3 can be a groove directly formed on the second side wall, or a groove formed by a protruding structure arranged on the second side wall, such as the connecting groove 3 formed by the two arc segments 5 described later.

[0050] When subjected to compression, the two arc-shaped segments 5 can deform to enlarge the opening of the connecting groove 3, so as to embed the connecting part 2 into the connecting groove 3.
[0051] Optionally, the connecting part 2 includes a transition section 21 and an end 22. One end of the transition section 21 is connected to the first sidewall, and the end 22 is connected to the other end of the transition section 21.
