  • Publication number: 20220228409
    Abstract: A pivot device with an interlocking lifting mechanism includes a first interlocking member to which first and second shafts and a second interlocking member are pivotably connected. A torque device is mounted around the first and second shafts. A third interlocking member is pivotably connected to the second interlocking member and includes a sliding groove. A fixing seat includes a pivotal member extending through the sliding groove. The second interlocking member is slidably received in a guiding groove of the guiding seat. When the first shaft pivots through a certain angle, the first interlocking member pivots about the second shaft and actuates the second interlocking member. The third interlocking member pivots relative to the fixing seat. The sliding groove slides relative to the pivotal member. The second distal end synchronously slides relative to the first guiding groove to lift an auxiliary screen unit connected to the third proximal end.
