[0010] Preferably, one end of the second spring is fixedly connected to the locking pin, and the other end of the second spring is fixedly connected to the inner surface of the lock block. By using the second spring, the elastic force can be applied to the locking pin, ensuring it remains inserted into the window frame.

[0011] Preferably, a magnetic ring is fixedly connected to the lever body, and the magnetic ring engages with the locking block. The magnetic ring provides auxiliary fixation for the lever.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model installs two back panels on the inside of the window frame, and each back panel is equipped with a support buckle. The number and position of the support buckles correspond to the louver strips, and the buckles are attached to the edge of the louver strips. In this way, the louver strips can be reinforced and supported, improving their wind resistance and making them less prone to deformation.

[0014] 2. This utility model features sliding sleeves that extend and retract via springs at both ends of the louvered strip. The sliding sleeves are equipped with locking blocks, which can be used to engage with the window frame laterally using the spring force. In this way, the louvered strip can be installed and removed simply by controlling the engagement and disengagement between the locking blocks and the window frame. This method is more convenient than the traditional welding method and also facilitates the replacement of individual louvered strips later, eliminating the need to replace the entire louvered strip if a single strip is damaged.
