I am working on a Grabber Pole. I need a way to close the clamp from the other end of the pole.
The jaws stay locked when closed until released.
I thought of using a bike brake cable and maybe a pulley?
Any other ideas?
I don't think you need the pulley, if you add an extension to the plastic "finger" that moves. (See my diagram below.) Attach your bike cable to that extension piece. It will increase your leverage, too.
I used a type of clamp that ratchets closed. The other clamps I found needed too much force to open.
The devil is in the details. Any line or wire (like a straightened coat-hanger) that doesn't stretch will be okay for the link to a normally-open spring "jaw" should work, no?
What you use at the other end is the place to have some sort of mechanism that will allow you to close and lock the gripper end.
You want to have the grabber-pole light enough to hold one-handed while you close the grip remotely.
If you use a lever at the operator end, you can choose the place on the lever where there is sufficient mechanical advantage to close and hold the gripper shut.
Great Idea: Good luck.
