I wanna make one but I don't know how it should hook onto bike.

It needs 2 degrees of freedom relative to the bike (yaw and pitch), but it must not roll relative to the bike. You need to be more careful with the design in terms of the center of gravity of the payload, and the location and angle of the yaw axis. Both of those will determine how your trailer handles when loaded. be careful, it's easy to design a single wheel trailer that handles very badly but you don't find out about it until you get it up to speed with a full load!
I've designed and built a few, mostly to test my designs, and settled on one that handles very nicely, but I don't use it all that much these days. Good luck, I'll be interested to see how it goes.... Just be careful in testing.
