How do I align my tool with my animation?

[wraith pollen]

Hi, my problem is that I want my tool to appear in different parts of the hand depending on the animation. However, with the Tool Grip Editor, I can only find a way to place it in one spot. I don't know how to adapt my tool to the animation. What should I do? How do I do it? Please help
