Abstract: A casing structure has an outer casing, a base plate, and a supporting unit. The base plate disposed inside the outer casing has an inner plate, an elastic arm, and a fixing body connected to the inner plate. The inner plate has a first plane and a second plane. The first plane is seamlessly abutted on the outer casing. One end of the elastic arm is angularly connected to the inner plate, and the other end of the elastic arm is defined as a free, and resiliently movable end. The fixing body is arranged correspondingly to the elastic arm. The supporting unit has a positioning body and a contacting body extended from the positioning body. The positioning body has a substantially frame shape, and the shape of the positioning body is matching to a space, which is surroundingly defined by the fixing body and the free end.

Abstract: The instant disclosure discloses a fixing structure of a data access device having a fixing tray and a handle. The fixing tray includes at least one fixing latch and at least one elastic member. One end of the fixing tray is a pivot and two hooks. The distance between the fixing latch and the pivot is shorter than that between the elastic member and the pivot. The other end of the fixing tray is an inserting section. One end of the handle is a hinge section, from which two cams are extended. The other end of the handle is an operational pull. The hinge section and the operational pull are connected by a connecting rod. The hinge section pivotally connects to the pivot. A fixing case with the fixing structure of a data access device is disclosed.
