The utility model discloses a novel fixed brake clamp for an external holding brake of an oil pumping unit, which is an external holding type fixed brake control device of an oil pumping unit in an oil field, and solves the problems of an original fixed brake in the practical use process. The novel fixed brake clamp consists of a U-shaped clamp and a top screw, wherein the U-shaped clamp is formed by welding a steel plate with the thickness being 10mm, the depth being 50mm and the height being 40mm; a top screw hole is arranged at the center of the clamping surface at the upper part of the U-shaped clamp away from the bottom of the U shape by 10mm, and a top screw is installed in the top screw hole; and the steel plate with the thickness being 10mm is welded below the U-shaped clamp. Compared with the existing fixed brake technology, the novel fixed brake clamp has simple operation, the fixed brake can be completed by only one person, the using time is short, the labor intensity of workers and the work danger degree can be reduced greatly, and the well drilling efficiency can be improved.
