ABSTRACT:
A mounting base structure for a swingable arm which is placed in an appropriate position of a wall sconce lamp, an upper and a lower securing adapters are used with a connecting member to pivotally connect the mounting base to a swingable arm. By inserting and fitting the square aperture of the adapter at one end of the swingable arm to a corresponding connecting body of a connecting member together, the assembly can be swung synchronously. By applying extrusion and stretching on both ends of the connecting body, the upper and the lower securing adapters can be integrated with the adapter on the swingable arm into a one-piece structure, preventing the electrical wiring from tangling and the swinging movement of the arm is secured and stable.
