Put the pink stick into the blue tube and push the stick to lock it.
Push it again to get the stick out.
The interaction between the blue spring pins (sliding in the radial holes of the yellow hollow cylinder) and the blue outer tube performs the locking function.
The red springs tend to push the blue spring pins outward.
The interaction between the red pins (fixed to the yellow hollow cylinder) and the fixed inner barrel cam maintains the push-push function. Watch an explanatory video:
