Allenkeyly Nested Telescope

A telescope, with a hexagonal cross-section, which, in order to telescope in, and out, requires untightening using an Allen key type of arrangement, and then tightening back up using an Allen key type of arrangement when it is in position (which is almost always fully extended out). The tightening can be achieved because the telescope itself goes around a corner, like an Allen key does. Well, it doesn’t go around a corner, it already is around a corner. It’s not as if it is currently in the act of going away from you and around a corner over there. It is already bent like that.
