NASA Handrail clamp assembly challenge

grabcad

This clamp features a simple one-handed attachment mechanism that secures it onto handrails. It has two joints, making docking and undocking effortless. The external parts (illustrated in blue) connect to the central portion (depicted in red) using two pins (shown in yellow). These detachable parts can be left in place during use. To loosen the clamp on the railing, rotate the central lock counter-clockwise; to secure it, turn clockwise. Note that colors are for illustration purposes only.
