Grab and move an object through the scene

Unity Engine
1

Hello everyone!
I have a problem with my project: I’m trying to create a simulation in which when I grab an object with my tool, it should attach to the tool and move with it untill I drop it.
I use the “OnCollisionEnter” function in order to detect the collision between the object and the tool and the grip is working well but I have to set the new position of the object on the tip of the tool, but it automatically set the new position on a different point and I don’t know how to solve this problem.
The tool has a tree-like structure in which the tip of the tool is one of the child game object.

I hope you can help me! Thanks in advice

So what specifically do you want? Do you want people to debug your description? Perhaps post you a tutorial series (I’m pretty sure a Google search would give you that) or something else?
