  "description_excerpt": "1. Technical Field\n\nThe disclosure generally relates to a hard disk drive mounting device, and an electronic device using the hard disk drive mounting device.\n\n2. Description of Related Art\n\nIn a computer, one or more hard disk drives are often used for storing information. The hard disk drives are mounted in the electronic device by hard disk drive mounting device. However, the hard disk drives are typically secured to the hard disk drive mounting device by screws. It is inconvenience to assemble or disassemble the hard disk drive from the hard disk drive mounting device.\n\nWhat is needed, therefore, is a hard disk drive mounting device to overcome the above described disadvantages.\n\nMany aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.\n\nFIG. 1 is an isometric, assembled view of an electronic device in accordance with an embodiment of the present disclosure.\n\nFIG. 2 is an isometric, exploded view of the electronic device of FIG. 1.\n\nFIG. 3 is an enlarged view of a rear end of a hard disk drive mounting device in FIG. 2.\n\nFIG. 4 is a top plan view showing an elastic arm in FIG. 2.\n\nFIG. 5 is an inner side view showing the elastic arm in FIG. 2.\n\nAn embodiment of the electronic device and the hard disk drive mounting device will now be described in detail below with reference to the drawings.",
