Fixing structure and adapting module assembling structure

The utility model relates to a fixing structure which is arranged in an electric controlling case, comprising two fairleads and a stopping elastic trip. After an adapting module imbedding in the electric controlling case and moving along a scheduled direction to a position with the guidance of the fairleads, the stopping elastic trip bounces and resists to the back side of the adapting module to fix and simply assemble with the adapting module. Besides, when a screw nut is locked in the external side of the electric controlling case, the utility model can easily lock the screw nut as a consequence of a fixing mechanism of the stopping elastic trip and fairleads which are arranged on the adapting module. The utility model also relates to a fixing structure and adapting module assembling structure.
