description The utility model discloses a small valve operation wrench which comprises an operation rod, a lower clamping jaw, an upper clamping jaw and an adjusting piece. The lower clamping jaw is arranged on the operating rod, and two lower clamping rods which are arranged at an interval are arranged on the lower clamping jaw; the upper clamping jaw is arranged on the adjusting piece, and an upper clamping rod is arranged on the upper clamping jaw; a clamping space is formed by the upper clamping rod and the lower clamping rod; the adjusting piece is movably connected with the operating rod and used for adjusting the upper clamping rod to be close to or away from the operating rod so as to adjust the size of the clamping space. A triangular clamping space can be formed through the two lower clamping rods and the upper clamping rod, compared with an existing F-shaped wrench, a valve can be clamped more effectively, the size of the clamping space can be adjusted through the adjusting piece, the applicability of the wren
