In the walls of the brackets, through guide grooves are made for spring-loaded clamps movably installed in them. Cam males contain cut-out openings with guide edges for spring-loaded insertion of latches into them. The brackets are all-purpose with the possibility of installation in a casing with options for jointed folding of the multi-copter beams in horizontal or vertical planes. The guide edges of the cut-out openings of the cam males are made with angular bevels. In this case during flight the edges of the male openings are in contact with the guide grooves of the brackets by means of spring-loaded clamps with the possibility of jamming.

EFFECT: increased reliability of the design, expansion of capabilities and versatility.
