This invention relates to a disassembly tool for the output end of a hydraulic coupler, comprising a puller, a ball-head push rod, a release sleeve, and an adjusting disc. The puller includes a hydraulic push rod and pull claws. The release sleeve has a central hole with a T-shaped cross-section, a convex ring at the top, and threads on its lower outer wall. The adjusting disc is a circular disc with threads on its inner wall. The inner diameter of the circular disc matches the lower outer diameter of the release sleeve and is smaller than the outer diameter of the top ring of the release sleeve. The ball-head push rod is installed in the central hole of the release sleeve, and its outer diameter is not greater than the inner diameter of the hole. This invention utilizes the engagement between the threads on the outer wall of the release sleeve and the release threads on the inner wall of the deep hole at the output end of the coupler. The force is transmitted through the ball-head push rod to the shaft end of the driven equipment, separating the coupler from the shaft end. The ball-head push rod effectively protects the shaft end of the driven equipment from damage and prevents wear and failure of the release threads.
