Claim:
A case fixing mechanism, including: a fixing device, located at a first case part and displaceable with said first case part; an assembling part, located at a second case part, for containing the fixing device; a combination device, movably located at the second case part to engage or disengage the fixing device on the first case part with the assembling part on the second case part; and a control device, located at the second case part, for controlling the combination device to be at a first location or a second location, the control device further connected to an assistant component, and the assistant component being disposed on the second case part; wherein the combination device interlocks the fixing device with the assembling part to combine the first case part and the second case part when the control device controls the combination device to be at the first location, and when the control device controls the combination device to be at the second location, the combination device does not interlock the fixing device with the assembling part thus enabling the first case part to be separable from the second case part.
