Abstract: A housing having a fixing mechanism for fixing at least one electronic device includes a housing body and a pivotable fixing mechanism. The fixing mechanism includes a first positioning device and a second positioning device. The second positioning device has a first fixing member for accommodating a electronic device, and a second fixing member detachably engaged with the first positioning device to fix the second positioning device in a first position on the first positioning device. When the second fixing member is disengaged, the second positioning device is fixed in a second position on the first positioning device, and when the first positioning device is rotated outwards relative to the housing body, the second positioning device can be removed or installed on the first positioning device through the second fixing member.
