For example, referring to fig. 4, when the door panel 20 connected to the first link 210 is rotated by an external force, the first link 210 is pulled to rotate by the rotating member 100 connected thereto. Because the two rotating members 100 are engaged and driven, the rotating member 100 connected with the second connecting rod 220 also rotates and drives the second connecting rod 220 to move, so as to drive the other door panel 20 to rotate.
