What it does?
This product is very simple to use and is user-friendly. To engage or lock the mechanism, the inner tube should be moved upwards, by moving the extrusion on it via the slot on the outer tube. To make sure it doesn’t fall back through the slot, the inner tube should be turned to bring them to an out-of-alignment state. In this position tilting of the rod is constrained, because the inner tube, whose motion is constrained by the fixed outer tube is overlapping the tilting rod, thus constraining it too. To disengage or to let the tilting rod move freely again, the extrusion shall be slid back through the slot. This would bring it back to the inner tube not overlapping the tilting rod condition, thus allowing it to move freely.
