Through the cooperation of the first slide rail 321a and the first slider 44, the connecting rods 32 of the torque modules 3 can drive the cover plates 4 to rotate, and the first slide rail 321a cooperates with the The movement trajectory of the first slider 44 of the cover plate 4 extends and can be adjusted according to requirements. In addition, the cooperation between the second slide rail 321b and the second slider 322a can compensate for the difference in the movement trajectory between the first rod 321 of the links 32 and the body 200.

In summary, the present invention can rotate synchronously around the two rotation axes A spaced apart from each other with respect to the same motion base 21 and provide the two same motion elements 22 provided for the two bodies 200 respectively, so that When the two bodies 200 are changed between the expanded state and the collapsed state, they rotate in reverse synchronously around the two rotation axes A, respectively, so that the two bodies 200 maintain a gap at the folded position when they are collapsed. In order to avoid damage to the bending radius of the bendable screens installed on the two bodies 200 being too small.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
