Fixing mechanism with quick-releasing function and related electronic device

An electronic device with quick-releasing function, comprising:

• a base adapted to support a plurality of electronic components;
• a cover assembled with the base to cover the plurality of electronic components, the cover comprising a constraining portion;
• and
• at least one fixing mechanism disposed on the base, the fixing mechanism comprising:
• a buckling component, comprising:
• a main body whereon a hole is formed;
• a first wedging portion formed on an inner wall of the hole;
• a hooking portion disposed on the main body and stretching from the main body outwardly at a first direction, the hooking portion being adapted to engage with the constraining portion;
• and
• a pushing portion disposed on a position of the main body adjacent to the hooking portion and stretching from the main body outwardly at a second direction different from the first direction, the pushing portion being adapted to push the constraining portion;
• and
• an actuating component adapted to drive rotation of the buckling component, the actuating component comprising:
• a shaft body piercing through the hole and rotatably disposed on the base;
• and
• a second wedging portion formed on the shaft body and wedged with the first wedging portion, the shaft body being adapted to revolve on a structural axial direction of the shaft body to switch the buckling component between a first position and a second position, the hooking portion being engaged with the constraining portion to constrain a relative movement between the cover and the base while the buckling component is located in the first position, the pushing portion pushing the constraining portion to separate the cover from base while the buckling component is located in the second position.
