The electronic device is provided with at least one assembly hole. The fastening device includes a fastening assembly and a plate. The fastening assembly includes a buffer and a fastening element inserted through the buffer. The fastening element includes a rod portion, a fastening portion at one end of the rod portion, and a head portion at the other end of the rod portion. The fastening portion is fastened in the assembly hole. The plate includes a first positioning hole and a second positioning hole communicating with the first positioning hole. A diameter of the first positioning hole is greater than a diameter of the second positioning hole, and a diameter of the head portion is less than the diameter of the first positioning hole and greater than the diameter of the second positioning hole. ## Claims ### Claim 1 A fastening device for securing and protecting an electronic device, the electronic device being provided with at least one assembly hole, and the fastening device comprising: a fastening assembly, the fastening assembly comprising: a buffer; and a fastening element inserted through the buffer, the fastening element including a rod portion, a fastening portion at one end of the rod portion, and a head portion at the other end of the rod portion, wherein the fastening portion is fastenable in the assembly hole; a plate, including a first positioning hole and a second positioning hole communicating with the first positioning hole, wherein a diameter of the first positioning hole is greater than a diameter of the second positioning hole, and a diameter of the head portion is less than the diameter of the first positioning hole and greater than the diameter of the second positioning hole, so that the head portion is engaged with the second positioning hole, and the electronic device is secured over the plate, wherein the plate further includes a first surface, a second surface opposite to the first surface, and an extension hole passing through the first surface and the second surface, wherein a first direction is between the first positioning hole and the second positioning hole, and the extension hole is formed along the first direction and between the first positioning hole and the second positioning hole; and two pillar-shaped protruding portions protruding from the second surface and disposed at two sides of the extension hole, respectively, the buffer being in contact against the first surface, the head portion and the two pillar-shaped protruding portions being disposed correspondingly so as to prevent removal of the head portion from the second positioning hole. ### Claim 2 (depends on 1) The fastening device of claim 1, wherein the buffer further comprises two flanges, a recess between the two flanges, and a through hole for insertion of the rod portion, and a diameter of the through hole is greater than or equal to a diameter of the rod portion. ### Claim 3 (depends on 2) The fastening device of claim 2, wherein an outer diameter of each of the flanges is greater than the diameter of the head portion and the diameter of the first positioning hole, so that the buffer contacts against the plate corresponding to the first positioning hole and the second positioning hole. ### Claim 4 (depends on 2) The fastening device of claim 2, wherein a length of the rod portion between the head portion and the fastening portion is less than or equal to a height of the buffer, and the recess of the buffer is elastically deformable. ### Claim 5 (depends on 1) The fastening device of claim 1, wherein the fastening portion includes an external thread for fastening in the assembly hole, or the fastening portion is a plug for interference fit with the assembly hole. ### Claim 6 (depends on 1) The fastening device of claim 1, further comprising a pad, the pad being disposed between the buffer and the head portion. ### Claim 7 (depends on 1) The fastening device of claim 1, wherein a width of the extension hole in a second direction is equal to the diameter of the second positioning hole in the second direction, wherein the second direction is perpendicular to the first direction. ### Claim 8 (depends on 7) The fastening device of claim 7, wherein the diameter of the first positioning hole in the second direction is greater than the diameter of the second positioning hole in the second direction. ### Claim 9 (depends on 1) The fastening device of claim 1, wherein the first positioning hole and the second positioning hole are each a round hole, and the extension hole is a straight groove flush with the outer diameter of the second positioning hole. ### Claim 10 (depends on 1) The fastening device of claim 1, wherein the two pillar-shaped protruding portions are disposed adjacent to two sides of the extension hole, respectively, and the two protruding portions are in a curved shape or in a semi-circular shape. ### Claim 11 (depends on 1) The fastening device of claim 1, wherein the two pillar-shaped protruding portions protrudes from the second surface with a height less than a height of the head portion. ### Claim 12 (depends on 1) The fastening device of claim 1, wherein the plate further includes a restriction plate, and the restriction plate extends out of an edge of the first positioning hole to protrude from the second surface, so as to prevent the head portion from moving toward a direction opposite to the second positioning hole. ### Claim 13 (depends on 1) The fastening device of claim 1, wherein the fastening element is a bolt, a positioning pillar, a dowel, or a pin. ### Claim 14 (depends on 1) The fastening device of claim 1, wherein the buffer is made of rubber or silicon, or consists of a spring.
