The hinges of this apparatus appear to be attached (directly or indirectly) to a 2x4 wall stud. Many of these studs extend from foundation to roughly the ceiling of the room that they form.
My first reaction, is that the swiveling support operates as a lever, magnifying the force at the 'plug end' at the wall where it attaches. Over years of use, somebody might casually rest a hand on the swivel, pulling it downward at its farthest extreme. The weakest link might be the nails that hold the 2x4 to one or more 2x4s inside the wall. That 2x4 must be able to withstand two forces that seek to pry it out of the wall:
1. Potentially, in the 'stowed' configuration, the swivel lies against the wall, and might be used to pull the 2x4 in rotation within the wall itself;
2. In the 'extended' configuration, the torsion could operate to pull the 2x4 out, and away from the wall, making the 2x4 rotate like a hammer, with a Tesla potentially, operating in the role of a nail.
Hopefully, you aren't going to be visited by nephews, nieces, children under the supervision of a babysitter, etc., who might use the device for any form of entertainment. Now this could be remedied by applying an electric potential to the bare metal of the device, to prevent small humans and animals from persistently grasping the device?
