Manipulator for transformation of numerical control machine tool

The utility model discloses a numerical control machine tool transformation mechanical arm which comprises a base, a plurality of threaded holes are formed in the base in a penetrating mode, the multiple threaded holes are matched with the four corners of the base, threaded rods are in threaded connection with the interiors of the threaded holes, a fixing column is fixedly connected to the top of the base, and the fixing column is fixedly connected to the top of the base. A wire slotted hole penetrates through the side, away from the fixing column, of the top of the base. The whole device is transferred to the top of a numerically-controlled machine tool needing to be used, the threaded rod is used for fixing the position between the base and the numerically-controlled machine tool, after fixing is completed, a connecting line sequentially penetrates through the two line outlet holes, the locking belt can be pulled according to the length of the connecting line, and therefore the locking belt can be fixed to
