The invention discloses a bracket for adjusting an angle of a photovoltaic cell panel, and belongs to the technical field of brackets of photovoltaic cell panels. Three universal spheres are fixedly mounted at the back of the photovoltaic cell panel; sphere centers of the three universal spheres are connected to form a right triangle; the universal spheres comprise universal sphere bases and universal sphere balls; the universal sphere bases are fixedly connected with the back of the photovoltaic cell panel; the universal sphere balls are positioned in the universal sphere bases and can freely rotate in the universal sphere bases; the universal sphere ball of each universal sphere is fixedly connected with a bracket rod; the bracket rod of the universal sphere at the right angle peak remains fixed in an adjustment process; and the bracket rods of the other universal spheres move in the adjustment process. The bracket is simple in structure, high in reliability, flexible in mounting mode, and low in cost.
