Hello everyone I am new to this board, and I am seeking to learn as much as I can.


I have seen some cellphone cradle/mount that have a sort of ratchet and pawl or freewheel mechanism inside which with a press of a button can extend or retract to hold the phone in place. I have taken an interest as to how something like this works, with my limited understanding i get how it can extend but its really cool how it also retracts.  Could anyone with knowledge on the subject shed some light? i would sincerely appreciate it.



heres a link of a recent mount I was looking to purchase and piqued my interest:
