The invention belongs to the technical field of connector appliances and particularly relates to an anti-drop connector component mechanism. The anti-drop connector component mechanism comprises an aluminium alloy male connector body and an aluminium alloy wrench component, wherein the aluminium alloy wrench component comprises a wrench ferrule; a wrench locking auxiliary hook is arranged on one side of the wrench ferrule; a socket head cap screw is screwed into the outer side wall, positioned at the lower end surface of the wrench ferrule, of a ferrule segment; and the head part of the socket head cap screw can prevent the wrench component from dropping off the ferrule segment of the aluminium alloy male connector body. The anti-drop connector component mechanism has the following beneficial effects: the weight can be reduced, the use is labor-saving, the wrench component can be effectively prevented from dropping off a male connector, and the sealing performance of connection between the male connector and a female connector is enhanced.
