By this arrangement, the frame 10 and the buckle 20 can fix the hard drive 2 into the rack by surrounding buckle means. On the other hand, when the buckle 20 disconnects from the buckling of the frame 10, the users do not need to use any tools to remove the hard drive 2 from the frame 10, thereby achieving the goal of quick assembling/disassembling.
Referring to FIGS. 4 and 5, when using the surrounding-buckle type mobile hard drive rack 1, the frame 10 needs to be expanded back to rectangle shape, and the hard drive 2 is inserted into the accommodation space 100 of the frame 10 from the insertion opening 101. And then, rotating the buckle arm 20 to close the insertion opening 101, and the elastic insertion plate 21 of the buckle arm 20 penetrates through the insertion slot 1121 of the cover plate 112 into the buckle trough 110. The blocking element 211 of the elastic insertion plate 21 will block against one side of the buckle trough 110. Thus, the elastic insertion plate 21 will be buckled to the buckle trough 110, and the hard drive 2 can be positioned into the accommodation space 100 surrounded by the frame 10 and the buckle arm 20.
It is noteworthy that, the accommodation space 100 is a pierced compartment, the hard drive 2 is accommodated into the accommodation space 100 to fully expose two opposite side surfaces. Since the frame 10 of the preferred embodiment of the present invention is a pierced frame, the thickness of the surrounding-buckle type mobile hard drive rack 1 can be reduced when the hard drive 2 is accommodated into the accommodation space 100, thereby allowing more surrounding-buckle type mobile hard drive racks 1 to be accommodated in the inner space of the server. Besides, since the frame 10 of the preferred embodiment of the present invention is a pierced frame which is good for ventilation, the heat dissipation efficiency of the hard drive 2 can be improved as well.
Referring to FIG. 5, in the preferred embodiment of the present invention, one side of the hard drive 2 is provided with a first positioning hole 3, and a first positioning pin 1131 is provided on the supporting plate 113 on a side facing the hard drive 2.

The pulling handle 60 covers the cover plate 112 on a side away from the accommodation space 100 by the interconnection of the first buckle part 61 and the second buckle part 1122. In the present embodiment, the first buckle part 61 is a Mister, and the second buckle part 1122 is a bump, but not limited thereto.
In a preferred embodiment of the present invention, the cover plate 112 is provided with an elastic pressing ring 1123. The elastic pressing ring 1123 deforms under an outer force and forces the second buckle part 1122 to unbuckle the first buckle part 61. Besides, a pressing hole 1124 is provided on the cover plate 112 at the same side of the elastic pressing ring 1123. Moreover, the pulling handle 60 is correspondingly provided with an opening 62 lager than the pressing hole 1124.
As embodied in FIG. 8, when a hard drive 2 is replaced or removed from the surrounding-buckle type mobile hard drive rack 1, the pulling handle 60 needs to be pulled outward. When in use, the outer force reaches the opening 62 and the pressing hole 1124 to further push the elastic pressing ring 1123, thereby forcing the first buckle part 61 to unbuckle with the second buckle part 1122 to release the pulling handle 60. At last, users can use single hand to press the elastic insertion plate 21 in the buckle trough 110 to force the elastic insertion plate 21 to deform. Meanwhile, the deformation of the elastic insertion plate 21 can enable the blocking element 211 to disengage from the buckle trough 110. As such, the buckle arm 20 is unbuckled from the cover plate 112 and rotates to a side to expose the insertion opening 101 (as shown in FIG. 3), thereby removing the hard drive 2.
Furthermore, referring to FIG. 9, when the hard drive 2 is combined with a connector 5 (ex. eSATA), one side of the bottom plate 111 corresponding to the connector 5 is formed with an accommodation trough 1112. By this arrangement, the surrounding-buckle type mobile hard drive rack 1 can accommodate hard drives 2 with different specification, and thus improving the practicability of the present invention.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
