Clam shell bucket for crane

[Madman]

I am working on my next project. I have one of those toy tower cranes with a wired remote. I would like to install a clam shell bucket on it. I saw one on Youtube that doesn't need two cables to operate it. It has some sort of rod running down it's center, that opens and closes the clam shell. I don't know exactly how it works yet. Would anyone have any idea as to where I could procure one?

It's not that hard to rig a two cable one...

but here's your single line bucket....
