Quick disassembly structure for computer case

A quick disassembly structure for computer case, comprising:

• a first casing, comprising:
• a cover, including a hole passing through a top surface of the cover;
• a first casing fastener, fixed to a bottom surface of the cover and adjacent to the hole, including a first hook part fixed to a side of the first casing fastener and a pivot shaft protruding on another side of the first casing fastener, the pivot shaft disposed below the hole;
• and
• a limit fastener, disposed adjacent to a side of the first hook part, including a limit fixing groove surrounding a side of the limit fastener;
• a quick disassembly member, comprising:
• a toggle pin component, inserted through the hole at a side, the toggle pin component comprising:
• a toggle pin component body;
• a pivot hole, disposed on a side of the toggle pin component body, the toggle pin component body pivoted to the pivot shaft through the pivot hole;
• and
• a toggle extension member, adjacent to the pivot hole and extends along the side of the toggle pin component body;
• a sliding plate, disposed adjacent to the bottom surface of the cover, and comprising:
• a sliding plate body;
• a sliding limit groove, formed on a top surface of the sliding plate body and slides within the limit fastener;
• a second hook part, disposed on a side of the sliding plate body;
• a transmission plate, extended and fixed to the side of the sliding plate body, corresponding to the toggle extension member;
• and
• a third hook part, which is adjacent to the transmission plate and fixed to the side of the sliding plate body;
• and
• an elastic component, an end of the elastic component hooked by the first hook part, and another end of the elastic component hooked by the second hook part;
• and
• a second casing, a side including a tenon corresponding to the third hook part;
• wherein, when the toggle pin component is actuated, the toggle pin component rotates clockwise around the pivot hole as a rotating axis, driving the toggle extension member to push the transmission plate to move toward a first direction;
• while the toggle extension member pushes the transmission plate, the second hook part pulls and stretches the elastic component, and the third hook part moves toward the first direction to disengage from the tenon, causing the first casing and the quick disassembly structure to separate from the second casing toward a second direction.
