The name of the invention is function detection equipment of a dual-circuit board. The equipment belongs to the technical field of function detection of automobile electronic products and mainly solves the problems in existing function detection equipment of a dual-circuit board that a manufacture period is long, construction cost is high, and a vertical pressing rod has a short stroke. The equipment is mainly characterized in that box bodies comprise a bottom box body, a middle box body and an upper box body; two circuit board clamps are located right above the bottom box body; an electronic load is located inside the upper box body; a side connecting-rod rotation-type linkage mechanism is installed in the middle box body, the side connecting-rod rotation-type linkage mechanism comprises a rotation rod, a rotation shaft, an irregular roller, a spring and a linkage rod, and the linkage rod is connected to a clamp cover plate; and an LED digital tube voltage meter, an electronic load socket, an LED digital tube current meter and a state indication lamp are disposed on the front face of the upper box body. The equipment provided by the invention is characterized by a short manufacture period, low cost, visibility and convenience, a long adjustable stroke of the circuit board clamps and the like, and is mainly used for function detection of the dual-circuit board.
