A fast installation/removal structure includes an upper board, a lower board, and an installation/removal lever. The upper board has hooking grooves and at least a positioning pin. The lower board has snap fitting devices and at least a sliding slot through which slidably inserts the positioning pin. A front end of the lever is pivotally connected to the lower board there below, and has a guide groove through which the positioning pin inserts. A rear end of the lever is externally accessible to allow manipulation by the user. With the circuit board securely fastened thereon, the upper board is placed on the lower board. The snap fitting devices respectively engage through the hooking grooves. By turning the lever, the positioning pin slides along the sliding slot to have the snap fitting devices respectively snap fit through the hooking grooves, thereby fastening the upper board to the lower board.

Fast installation/removal structure for circuit board

A fixing structure for extension cards includes a set of extension slots, a positioning element and a resilient plate. The positioning element engages on an external side of the set of the extension slots, and the resilient plate is fixing on an internal side of the set of the extension slots. A folded edge of the resilient plate is inserted through a first mounting slot of the positioning element to firmly secure the positioning element on a computer casing. A stem of the resilient plate is pulled toward an inside of the computer casing to release the folded edge of the resilient plate from the first mounting slot of the positioning element so that the positioning element is pushed upward to disengage from the set of extension slots.
