Abstract: The present disclosure provides a linkage structure including an upper bracket and a lower bracket, wherein said upper bracket includes a first linkage unit, a second linkage unit, a middle piece and two sets of adjusting pieces, one end of said middle piece is connected to said first linkage unit and the other end is connected to said second linkage unit; wherein at least one adjusting piece in each set of adjusting pieces is connected rotatably to said first linkage unit or said second linkage unit. According to the linkage structure of the present disclosure, mechanical tilt can be achieved by driving two sets of adjusting pieces to move in coordination, it can ensure the accuracy of mechanical tilt, realize mechanical tilt at any angle, and the operation process is friendly and safe.
