Abstract:
1. A computer chassis comprising: a housing; an elastic element mounted in the housing and comprising two free ends; a scissor structure fixed to the housing, comprising a first arm, a second arm, a third arm, and a fourth arm, wherein the first arm and the second arm are an integral structure, the third arm and the fourth arm are an integral structure, the first arm and the second arm, and the third arm and the fourth arm are capable of rotating around an axis fixed in the housing, a free end of the first arm defines a first stopper, a free end of the third arm defines a second stopper, a free end of the fourth arm and a free end of the second arm are connected to the two free ends of the elastic element respectively; and two hard disk drawers slidably received in the housing and capable of being drawn out from the housing, the scissor structure being set between the two hard disk drawers, each of the two hard disk drawers comprising a resisting element; wherein when both of the two hard disk drawers are not drawn out, the fourth arm and the second arm of the scissor structure set between the two hard disk drawers are sandwiched between the resisting elements of the two hard disk drawers, causing the elastic element to be deformed, the first stopper and the second stopper do not contact with the resisting elements of the two hard disk drawers, respectively, and when one of the two hard disk drawers is drawn out, the resisting element of the hard disk drawer being drawn out moves to cause the second arm to rotate around the axis under an elastic force generated by the elastic element, the first arm also rotates around the axis to make the first stopper engage with the resisting element of the other hard disk drawer and prevent the other hard disk drawer from being drawn out.
