The invention discloses a method for detecting a phthalate plasticizer in a plastic toy by a fluorescence method.Oscillation equipment comprises a box body, a first movable groove is formed in one side of the box body in a penetrating mode, a second movable groove is formed in the other side of the box body in a penetrating mode, and a swing mechanism and a driving mechanism are arranged in the box body; the swing mechanism comprises a supporting plate, a first movable frame and a second movable frame, the supporting plate is fixedly connected into the box body, a sliding groove is formed in the front face of the supporting plate in a penetrating mode, a shaft rod is fixedly connected to the supporting plate, and a first gear is rotationally connected to the shaft rod. The test tubes are clamped by the clamping mechanism, the swing arm is driven to move by the first gear, so that the first movable frame and the second movable frame are driven to reciprocate, the plurality of test tubes are driven to synchrono
