[0018] Compared with the prior art, the beneficial effect of the present utility model is: This replaceable hydraulic ball head disassembly tool

[0019] An installation base, a rotating block and an installation column are provided. When replacing the clamping frame, the rotating block is rotated to make the rotating block parallel to the rectangular groove. At this time, the clamping frame can be taken out upward. After replacing it with a new clamping frame, the rotating block is rotated to make the rotating block perpendicular to the rectangular groove, and the fastening nut is tightened and fixed. Such a loading and unloading method is simple and efficient, facilitating the replacement of the clamping frame, and thus different ball heads can be disassembled.
