Flat single shaft tracking system

The invention discloses a flat single shaft tracking system. The flat single tracking system comprises a push rod (1), a push-pull rod (2) and a connecting mechanism for connecting the push rod (1) with the push-pull rod (2), wherein the connecting mechanism comprises two articulating elements (31) articulated with the push rod (1), and the two articulating elements are respectively and fixedly connected with a corresponding push-pull rod (2). According to the technical scheme, the push-pull rod respectively and fixedly connected with two articulating elements can generate a mounting angle adaptive to a mounting field through two articulated articulating elements; therefore, even if the mounting field has poor flatness or the horizontal mounting error is produced due to foundation settlement, all rows of mounting photovoltaic generating components can be conveniently connected in series to realize the linkage of the all rows of mounting photovoltaic generating components.
