Claim:
A fixing/releasing mechanism configured to connect a first unit and a second unit and mounted on the first unit, said mechanism comprising: a press-fit button configured to move when under a pressure, said press-fit button configured to move in a direction of the pressure and to automatically return to the original position when the applied pressure disappears; a snap catch mechanism comprising a lock hook configured to couple the first unit to the second unit and to release the second unit from the first unit, said snap catch mechanism further comprising a lock hook buffer, wherein, upon mounting, said lock hook buffer is fixed on the first unit, and wherein said lock hook buffer comprises an inclined top portion that is exposed on a front surface of the first unit to buffer impact generated when said lock hook releases the second unit; and a transmission mechanism connected to said press-fit button and configured to transmit the pressure applied to said press-fit button to said snap catch mechanism such that said lock hook generates protrudable and retractable movement in order to fix the first unit to the second unit or to release the second unit from the first unit.
