[0002] As people's living standards improve, their requirements for smart and comfortable living environments are getting higher and higher. Therefore, the degree of home automation is getting higher and higher. People often install window openers on windows to intelligently control the opening or closing of windows. Users can remotely control the windows, which is convenient and simple to use. Even when users are away from home, they can open or close windows at any time according to their needs.

[0003] However, in actual use, the existing window openers not only open and close the door and window components by electrically driving the motor to drive the input disk to link the output disk, but also manually turn the handle to drive the door and window components to open and close the windows when encountering a power outage or the window opener motor is damaged. However, when manually opening and closing the window opener, since the door and window components are engaged with the output disk, when the door and window components move, the manual load is very large, and the manual switch is very inconvenient to use, especially when used on a motor with a large primary load. If a fire occurs, resulting in a power outage or motor damage, the doors and windows connected to the window opener will be difficult to open, hindering the user's quick escape.
