[0032] Specifically, connector 9 and flexible smoke curtain body 7 are installed by plugging in. Bolt 20 extends through threaded hole 10 and through hole 8 to the inside of threaded hole 12. The cross-section of connector 9 is Y-shaped. The advantage is that workers can quickly install connector 9 by inserting the flexible smoke curtain body 7 into positioning groove 11 and then extending bolt 20 through threaded hole 10 and through hole 8 to the inside of threaded hole 12. The design of positioning groove 11, bolt 20, threaded hole 10, through hole 8, and threaded hole 12 facilitates the installation and disassembly of connector 9, making subsequent maintenance and repair convenient.

[0033] Specifically, the connecting plate 13 has a U-shaped cross-section. Connecting plate 13 is compatible with hook 2 and hook 6. The advantage is that the operator first rotates hook 6 90°, then moves connecting plate 13 above hook 2. Afterwards, the operator releases the hand that rotated hook 6, the torsion spring 5 returns, and hook 6 returns to its original position. Finally, connecting plate 13 is inserted into the interior of hook 2 and hook 6, enabling rapid installation of the flexible smoke curtain body 7.
