• a first lever, comprising a main pole body, an operating part and a second guide pillar, the main pole body having a first tail end, a first head end and a linear third guide groove, the first tail end being pivotally connected to the first inner side face and being adjacent to the first rear edge and the first upper edge of the first base plate, the operating part being formed on the first head end and being located outside the first front edge of the first base plate, the second guide pillar being formed on the main pole body and being capable of being operated in the first guide groove to move between the first upper end point and the first lower end point, the third guide groove being formed between the first head end and the first tail end and having a front end point and a rear end point, the front end point being toward the first head end, the third guide groove extending from the front end point toward the first tail end to the rear end point, and the third guide groove and the second guide groove crossing and overlapping;
• a sliding plate, comprising a second base plate and a third guide pillar, the second base plate having a second outer side face, a second inner side face, a second front edge, a second rear edge, a second upper edge, a second lower edge and a plurality of linear fourth guide grooves, the third guide pillar being formed on the second outer side face, each fourth guide groove corresponding to one of the first guide pillars and having a respective third upper end point and a respective third lower end point, the sliding plate being placed on the first inner side face of the first base plate and the main pole body with the second outer side face, such that the third guide pillar is placed in the third guide groove and the second guide groove, and that each first guide pillar is placed in the corresponding fourth guide groove, the first guide groove being located outside the second front edge;
• a functional module interface card, comprising N first connectors and having a third outer side face, a third inner side face, a third front edge, a third rear edge, a third upper edge, and a third lower edge, N being an integer larger than 1, the N first connectors being formed at the third lower edge, the functional module interface card being mounted on the second inner side face of the second base plate with the third outer side face, the third rear edge and the second rear edge being adjacent to the first rear edge, the third upper edge and the second upper edge being adjacent to the first upper edge;
• and
• a second side cover, comprising a third base plate, a front shield and a rear shield, the third base plate having a fourth outer side face, a fourth inner side face, a fourth front edge, a fourth rear edge, a fourth upper edge, a fourth lower edge and a joint portion, the front shield being formed on the fourth outer side face and extending outward from the fourth front edge, the rear shield being formed on the fourth outer side face and extending outward from the fourth rear edge, the joint portion being located adjacent to the fourth upper edge and being fixed with the first joint member, such that the rear shield covers the third rear edge and the second rear edge, and that the front shield and the first front edge constitute a slit, the first head end of the main pole body passing through the slit,
• wherein when a user operates the operating part to rotate the main pole body to move the second guide pillar to the first upper end point of the first guide groove, the third guide pillar moves toward the front end point of the third guide groove and the second upper end point of the second guide groove, each first guide pillar moves toward the third lower end point of the corresponding fourth guide groove, the sliding plate is actuated to drive the functional module interface card to move toward the first upper edge relative to the first base plate until the N first connectors are at a closest position relative to the first upper edge,
• when the user operates the operating part to rotate the main pole body to move the second guide pillar to the first lower end point of the first guide groove, the third guide pillar moves toward the rear end point of the third guide groove and the second lower end point of the second guide groove, each first guide pillar moves toward the third upper end point of the corresponding fourth guide groove, the sliding plate is actuated to drive the functional module interface card to move toward the first lower edge relative to the first base plate until the N first connectors are at a farthest position relative to the first upper edge,
• wherein when the second guide pillar of one of the at least one first swappable device moves to the first upper end point of the first guide groove, said one first swappable device is inserted into the accommodating space from one of the at least one window such that the front shield of said one first swappable device fits into said one window,
• when the second guide pillar of said one first swappable device moves to the first lower end point of the first guide groove, the N first connectors of said one first swappable device are at the farthest position relative to the first upper edge to be mated with the set of N second connectors corresponding to said one window.
