AI Technical Summary
The existing curtain opener has a fixed connection between the support component and the hanging component, which makes it difficult to pass through the steps on the guide component, thus affecting the opening of the curtain.
Design a support mechanism including a rotating component, a support member, and a connector. The support member rotates with the rotating component through a movable connection, enabling it to pass through the steps on the guide when the curtain is opened and to be inserted into the hanging ring when the curtain is closed. The support member is kept close to the guide by using elastic elements and a pivot structure.
This allows the curtains to smoothly pass through the steps on the guide during the unfolding process, preventing them from losing contact and ensuring the stable support of the hanging rings and the smooth unfolding and closing of the curtains.
