The invention provides a connecting rod type turnover mechanism provided with a base assembly, a displacement seat and a connecting rod assembly. The base assembly is provided with a pivot connectionpart and an arc-shaped rail, wherein the pivot connection part is located on the side of the rail. The displacement seat is arranged on the rail of the base assembly. The connecting rod assembly is provided with a pivoting piece and a turnover piece. The two ends of the pivoting piece are connected with the turnover piece and the pivot connection part of the base assembly in a pivoted mode correspondingly. One side of the turnover piece is connected to the displacement seat in a pivoted mode, so that when the turnover piece rotates and makes displacement around the pivoting piece, the displacement seat is driven to make displacement on the rail of the base assembly, and thus the turnover piece pivots on the pivoting piece.
