A PCI card fastening device for fastening a PCI card to a chassis includes a latching plate fixed to the PCI card, a latching element slidably fixed to the chassis and a locking element. The latching element includes a latching hole and a latching portion. The locking element is rotatably fixed to the latching element, the locking element includes a pressing board and a hook, the hook includes a securing block. The latching plate is latched to the latching portion, the securing block is latched in the latching hole to latch the locking element to the latching element. After the securing block is released from the latching hole, the pressing board moves away from the latching element to release the latching plate between the pressing arm and the latching element.

1. A PCI card fastening device for fastening a PCI card to a chassis, the PCI card fastening device comprising: a latching plate fixed to the PCI card;a latching element slidably fixed to the chassis, the latching element including a main body, a latching portion protruding from an end of the main body, and a U-shaped mounting board protruding from the end of the main body and surrounding the latching portion, the mounting board comprising two opposite mounting sections and a connecting section connecting the mounting sections, each mounting section defining a latching hole;a locking element rotatably fixed to the latching element, the locking element including a pressing board and two hooks protruding from the pressing board, each hook including a pressing arm and a securing block;wherein the latching plate is latched to the latching portion, the securing block of each hook is latched in one of the latching holes to latch the locking element to the latching element so the latching plate is latched between the pressing board and the latching element to latch the PCI card to the chassis; after the pressing arm is pressed to cause the securing blocks to be released from the latching holes, the pressing board rotates relative to the latching element, allowing the latching plate to be released from the latching portion to detach the PCI card from the chassis. 2. The PCI card fastening device of claim 1, wherein the latching plate is substantially L-shaped, and includes a latching section and a bending section bending from the latching section, the latching section is latched with the PCI card, the bending section is latched between the pressing arm and the latching element when the securing blocks are latched in the latching holes. 3. The PCI card fastening device of claim 2, wherein the bending section defines a first latching groove and a second latching groove perpendicular to the first latching groove; the latching portion includes a first latching block latched in the first latching groove, and a second latching block latched in the second latching groove. 4. The PCI card fastening device of claim 3, wherein the latching element further includes a joint fixed to the connecting section, the locking element includes a shaft rotatably fixed to the joint so the locking element can rotate relative to the latching element. 5. The PCI card fastening device of claim 4, wherein the joint is an arcuate arm defining an opening, in which the shaft is rotatably fixed. 6. The PCI card fastening device of claim 5, wherein the pressing board includes a pressing surface defining a receiving groove corresponding to the latching portion, the latching portion is received in the receiving groove when the securing blocks are latched in the latching holes. 7. The PCI card fastening device of claim 1, wherein each hook further includes an extending arm protruding from the pressing board, the pressing arm protruding from a distal end of the extending arm toward the other hook; the securing block protruding from a surface of the extending arm opposite to the pressing arm. 8. The PCI card fastening device of claim 4, wherein the locking element further comprises a connecting board perpendicularly protruding from the pressing board, the connecting board defines a trough; the shaft is located in the trough. 9. A PCI card fastening device for fastening a PCI card to a chassis, the PCI card fastening device comprising: a latching plate fixed to the PCI card;a latching element slidably fixed to the chassis, the latching element including a main body, a latching portion protruding from an end of the main body, and a U-shaped mounting board protruding from the end of the main body and surrounding the latching portion, the mounting board comprising two opposite mounting sections and a connecting section connecting the mounting sections, each mounting section defining a latching hole;a locking element rotatably fixed to the latching element, the locking element including a pressing board and two hooks protruding from the pressing board, each hook including a pressing arm and a securing block;wherein the latching plate is latched to the latching portion, the securing block of each hook is latched in one of the latching holes to latch the locking element to the latching element so the latching plate is latched between the pressing board and the latching element to latch the PCI card to the chassis; after the securing blocks are released from the latching holes, the pressing board moves away from the latching element to release the latching plate between the pressing board and the latching element. 10. The PCI card fastening device of claim 9, wherein the latching plate is substantially L-shaped, includes a latching section and a bending section bending from the latching section, the latching section is latched with the PCI card, the bending section is latched between the pressing arm and the latching element when the securing blocks are latched in the latching holes. 11. The PCI card fastening device of claim 10, wherein the bending section defines a first latching groove and a second latching groove perpendicular to the first latching groove; the latching portion includes a first latching block latched in the first latching groove, and a second latching block latched in the second latching groove. 12. The PCI card fastening device of claim 11, wherein the latching element further includes a joint fixed to the connecting section, the locking element includes a shaft rotatably fixed to the joint so the locking element can rotate relative to the latching element. 13. The PCI card fastening device of claim 12 wherein the joint is an arcuate arm defining an opening, in which the shaft is rotatably fixed. 14. The PCI card fastening device of claim 13, wherein the pressing board includes a pressing surface defining a receiving groove corresponding to the latching portion, the latching portion is received in the receiving groove when the securing blocks are latched in the latching. 15. The PCI card fastening device of claim 9, wherein each hook further includes an extending arm protruding from the pressing board and a pressing arm protruding from a distal end of the extending arm toward the other hook; the securing block protruding from a surface of the extending arm opposite to the pressing arm. 16. The PCI card fastening device of claim 12, wherein the locking element further comprises a connecting board perpendicularly protruding from the pressing board, the connecting board defines a trough; the shaft is located in the trough.
