And in the replacement position, the third limiting studs 635 respectively abut the corresponding third unfolding end 626, and the second limiting studs 634 respectively abut the corresponding fourth unfolding end 646, and The second hard disk module 7 is located outside the frame 1. At this time, the hard disk 71 in the second hard disk module 7 can be extracted and replaced.

In addition, it should be particularly noted that each supporting device 61 further has two elastic pivoting members 65, and the elastic pivoting members 65 pivotally connect opposite ends of the corresponding first rod body 631 to the corresponding first A bracket 62 and a second bracket 64. In use, the pressing member 67 is first pressed to disengage the locking member 68 from the corresponding locking portion 647, since the opposite ends of each of the first rods 631 are pivotally connected to the corresponding first bracket 62, The two brackets 64, and when the locking portion 647 is not restricted by the engaging force of the latching member 68, the elastic pivoting member 65 generates an unfolded elastic biasing force to cause the first lever The body 631 is moved away from the first bracket 62 by a rising distance, and synchronously causes the third limiting protrusion 635 of the second rod 633 to approach the corresponding third unfolding end 626, respectively. The fourth limiting studs 636 of the second rod body 633 are respectively moved closer to the corresponding fourth unfolding end 646, thereby increasing the space that the user can extend into the rack 1.
