Traditional American-style outward-opening windows are usually equipped with a mechanical system to ensure that the window can be tightly locked to ensure safety and windproof and waterproof performance, and can be easily opened by the user for ventilation. This type of window is generally equipped with two main operating components: first, a side lever handle, which is connected to multiple internal or external locking points. The user needs to first release the locking point by pulling this handle to unlock the window; second, a hand-cranked arm is installed at the bottom of the window.
