A first slide groove is opened on the left side of the top of the base, and the first slider is located in the first slide groove. A second slide groove is opened on the rear side of the top of the base, and the second slide groove is located on the right side of the first slide groove. The second slider is located in the second slide groove. The first slide groove and the second slide groove are arranged perpendicular to each other. The lighting board is fixed between the first slide groove and the second slide groove. The first slider and the second slider are fixedly connected to the adjustment block by the first spring. The L-shaped pressing frame is detachably fixed to the adjustment block. In the initial state, the first spring is in a contracted state, and the bottom wall of the adjustment block abuts against the top wall of the base. The mobile phone backlight detection jig of the present utility model can adapt to mobile phone backlights of different specifications."
