Self locking cylindrical hinges?

[drtnt]

Hi everyone,

I have a ball machine which comes with a detachable handle, but I would like to make it fold so that I don't have to put it on and take it off when taking in and out of the car.

I would like to find something like the folding hinges that prams have where you push the buttons to unlock.

Does anyone have any idea where I can get my hands on those?

Thanks

What is it made of?
How is it constructed?
Picture would help.

The handle is made of aluminium.

Here are some photos of the machine including the handle:

What I want to do is cut it and add the hinge so that it fold over the top of the machine.
