Description

Technical Field

[0001] The utility model relates to the technical field of shutters, in particular to a shutter and an adjusting mechanism. Background Art

[0002] Venetian blinds are becoming increasingly popular because they take up little space before and after opening and provide good ventilation while ensuring privacy. Angle-adjustable Venetian blinds can also achieve simultaneous ventilation and sunshade functions, keeping the indoor air fresh while maintaining heat preservation and energy saving. Most existing Venetian blinds include a window frame. Multiple blades are rotatably arranged inside the window frame, and ratchets are fixedly connected to one side of each blade. A rack line is sleeved between the outer walls of the multiple ratchets.
