1. A coupling assembly, comprising at least one support part,
wherein the at least one support part comprises:
a first connector comprising a first cam and a first pin shaft at an end, the first pin shaft being arranged on a side of the first cam; and
a second connector comprising a support plate, a connection block and a support projection, the support projection having a support surface,
wherein:
the connection block is arranged side by side with the support projection along a rotation axis of the first connector, and has a pin hole with an aperture larger than an outer diameter of the first pin shaft in a predetermined plane parallel to the support plate; the first pin shaft is mounted in the pin hole; the support surface faces the first cam and interacts with the first cam;
when the first connector assumes a posture paralleling the predetermined plane, the first pin shaft is located on a first side of the pin hole, and the first cam is in contact with a first position of the support surface;
when the first connector assumes a posture intersecting the predetermined plane, the first pin shaft is on a second side of the pin hole, and the first cam is in contact with a second position of the support surface;
the second side and the first side are opposite sides of the pin hole in the predetermined plane, and a distance between the first position and the support plate is greater than a distance between the second position and the support plate.
