Abstract
A case structure includes an inner case base, a buffer outer case and a torsional spring. The inner case base has a corner area and a fixing column located at the corner area. The buffer outer case is movably overlapped on an outer side of the corner area. The torsional spring is sleeved on the fixing column and located between the buffer outer case and the inner case base. A first end and a second end of the torsional spring are respectively connected to the buffer outer case. When the force exerted on the buffer outer case causes the buffer outer case to move relative to the inner case base, the torsional spring correspondingly deforms and stores elastic potential energy. When the force exerted on the buffer outer case disappears, the torsional spring releases the elastic potential energy to reposition the buffer outer case.
