A tilting mechanism for synchronous expansion

The utility model discloses a tilting mechanism for synchronous expansion, including first base, still including: respectively through left side board and the right side board of articulated shaft with first base normal running fit, left side board department is fixed with upper left articulated shaft, right side ban chu is fixed with upper right articulated shaft, upper left articulated shaft and the mutual parallel arrangement of upper right articulated shaft have erect synchronizing shaft between upper left articulated shaft and upper right articulated shaft, should go up synchronizing shaft and perpendicular crisscross setting of upper left articulated shaft, and go up synchronizing shaft and upper left articulated shaft junction, and go up synchronizing shaft and upper right articulated shaft junction and all be equipped with and be used for the moment of torsion vertical transmission mechanism that the moment of torsion transmitted between perpendicular alternating axis. When the left side board rotates
