Computer casing with fastening device

摘要

A computer casing (100) includes a cage (90), a side panel (10), a top panel (30), and a fastening device (60) for securing the side panel to the top panel. The side panel has a plurality of hooks (15). The top panel defines a sliding slot (38) slidably accommodating the fastening device. A plurality of recesses (48) defined in one side of the top panel is in communication with corresponding through holes (46) defined in one slot wall (44) bordering the sliding slot. A plurality of through openings (70) is defined through the fastening device. A spring (74) is placed over a cross-shaped nub (72) on one end of the fastening device. When the hooks are extending into the through openings, the hooks drive the fastening device to compress the spring. The spring then decompresses, causing the hooks to snappingly engage the side panel with the top panel.
