The sliding seat is movably configured on the limit seat. At least one link assembly is respectively connected to the limit seat and the sliding seat. The rotating shaft passes through at least one connecting rod component and the sliding seat. When the rotating shaft rotates relative to the sliding seat, force is applied to at least one link assembly to drive the sliding seat to move along the limit seat and switch to a closed state or an unfolded state.

The electronic device of the present invention includes a first body, a bracket, a second body and a pivot device. The bracket is rotatably connected to the first body. The second body is arranged on the bracket. The pivot module is arranged between the first body and the bracket. The pivot module includes a limit seat, a sliding seat, at least one link assembly and a rotating shaft. The limit seat is fixed on the first body. The sliding seat is movably configured on the limit seat. At least one link assembly is respectively connected to the limit seat and the sliding seat.
