What's the name of this brass part? Answered
This is on an adjustable length cane, where this thing can be pushed into the inside of the tube to adjust length of the cane, and pushed out by a spring with a "click" sound to lock the length.
This is also on kayak paddles to select and lock the angle of the paddles.
In fact, this is fairly common and used in many other places... But I don't know its name. I want to use this on one of my project and I am not sure what name should I use to search for the parts.
Anyone can help? Thanks!
