A bracket structure is utilized to assemble an electronic device into a
case. The bracket structure includes a main bracket, a side bracket, a
pin, and a guiding groove. The main bracket has a chassis and a bracket
wall. The electronic device would be assembled on the chassis. The side
bracket would be disposed on a case wall of the case. The pin would be
protruded on a surface facing the side bracket of the bracket wall. The
guiding groove is disposed on the side bracket. The pin would slide in
the guiding groove to guide the main bracket into the case.
