Device with opening and closing performance

A device comprising:

• a first body;
• a second body coupled to the first body;
• and
• a rotating shaft connection mechanism coupled to the first body and the second body and comprising:
• N rotating shaft components, wherein an ith rotating shaft component of the N rotating shaft components comprises a rotating shaft, and wherein N is a positive integer greater than or equal to 1 and i is a positive integer;
• a connection component comprising:
• a first end coupled to the first body;
• and
• a second end coupled to the second body;
• and
• N movable linear components, wherein an ith linear component of the N movable linear components corresponds to the ith rotating shaft component and is wound around the rotating shaft, wherein the ith linear component comprises:
• a first segment coupled to the second body and configured to extend along the rotating shaft and pass through the connection component;
• and
• a second segment coupled to the second body and configured to extend along the rotating shaft and pass through the connection component,
• wherein a first rotation radius of the first segment is different from a second rotation radius of the second segment when the second body rotates relative to the first body in a first direction,
• wherein the first direction is perpendicular to a second direction,
• wherein the second direction extends from a first area of the first body away from the connection component to a second area of the first body that is closer to the connection component, and
• wherein a first plane of the first direction and the second direction is parallel to a second plane in which the first body faces a surface of the second body.
