What is claimed is: 1. A retention assembly comprising: a latch structure formed on a platform, the latch structure comprising an engaging portion and a latching portion; and a latch holder comprising a holding protrusion engaging with the latching portion of the latch structure, an elastic pushing
What is claimed is: 1. A retention assembly comprising: a latch structure formed on a platform, the latch structure comprising an engaging portion and a latching portion; and a latch holder comprising a holding protrusion engaging with the latching portion of the latch structure, an elastic pushing portion causing the latch holder to engage with or disengage from the engaging portion of the latch structure, an engaging portion engaging with the engaging portion of the latch structure, a resisting member, and a detachable latch fixed on a first end of the resisting member; wherein the holding protrusion of the latch holder is formed on a second end of the resisting member opposite to the first end, the pushing portion and the engaging portion are formed on the detachable latch, the latch holder is rotatable around the latching portion of the latch structure; the holding protrusion comprises a limiting block; the limiting block is longer than and spaced from the engaging block; the limiting block resists an end of the latching portion to prevent the resisting member from moving away from the platform. 2. The retention assembly as claimed in claim 1, wherein the pushing portion elastically deforms away from the platform so that the engaging portion of the latch holder engages with the engaging portion of the latch structure; the pushing portion elastically deforms away from the platform so that the engaging portion of the latch holder disengages from the engaging portion of the latch structure. 3. The retention assembly as claimed in claim 2, wherein the engaging portion of the detachable latch comprises at least one hook, and the engaging portion of the latch structure comprises at least one latching slot defined in the platform. 4. The retention assembly as claimed in claim 3, wherein the resisting member further comprises at least one holding piece formed at an edge thereof. 5. The retention assembly as claimed in claim 4, wherein the holding protrusion comprises an engaging block; the at least one holding piece and the holding protrusion are substantially perpendicular to the resisting member, but extending toward opposite directions. 6. The retention assembly as claimed in claim 1, wherein the limiting block is adjacent to an edge opposite to the holding protrusions and far from the edge forming the holding protrusions. 7. The retention assembly as claimed in claim 3, wherein the detachable latch further comprises a hooking portion, a fixing portion extending substantially perpendicularly from a first side of the hooking portion, and the pushing portion extending obliquely from a second side opposite to the first side of the hooking portion; the hooking portion forms the at least one hook. 8. The retention assembly as claimed in claim 3, wherein the platform comprises a seating surface, two opposite sidewalls, a top wall, a bottom wall opposite to the top wall, and a seating surface extending perpendicularly from four edges of the seating surface. 9. The retention assembly as claimed in claim 8, wherein the latching slots are defined in a first of the sidewalls adjacent to the top wall; the latching portion extends from an end of a second of the sidewalls toward the top wall; the latching portion comprises a latching piece extending at a free end thereof; the seating surface defines a plurality of expansion card slots spaced apart from each other. 10. A retention assembly for mounting covers to a platform, comprising: a latch structure formed on the platform, the latch structure comprising an engaging portion and a latching portion; and a latch holder comprising a resisting member, and a detachable latch fixed on a first end of the resisting member, the resisting member comprising a holding protrusion formed on a second end of the resisting member opposite to the first end and engaging with the latching portion of the latch structure, and the detachable latch comprising an elastic pushing portion, the pushing portion comprising an engaging portion formed on an edge of the pushing portion and engaging with the engaging portion of the latch structure; wherein the holding protrusion comprises a limiting block; the limiting block is longer than and spaced from the engaging block; the limiting block resists an end of the latching portion to prevent the resisting member from moving away from the platform. 11. The retention assembly as claimed in claim 10, wherein the pushing portion elastically deforms away from the platform so that the engaging portion of the latch holder engages with the engaging portion of the latch structure; the pushing portion elastically deforms away from the platform so that the engaging portion of the latch holder disengages from the engaging portion of the latch structure. 12. The retention assembly as claimed in claim 10, wherein the resisting member further comprises at least one holding piece formed at an edge thereof to resist an edge of each cover. 13. The retention assembly as claimed in claim 12, wherein the holding protrusion comprises an engaging block; the at least one holding piece and the holding protrusion are perpendicular to the resisting member, but extending toward opposite directions. 14. The retention assembly as claimed in claim 13, wherein the limiting block is adjacent to an edge opposite to the holding protrusions and far from the edge forming the holding protrusions. 15. The retention assembly as claimed in claim 14, wherein the detachable latch further comprises a hooking portion, a fixing portion extending substantially perpendicularly from a first side of the hooking portion, and the pushing portion extending obliquely from a second side opposite to the first side of the hooking portion; the hooking portion forms the at least one hook. 16. The retention assembly as claimed in claim 10, wherein a plurality of protrusions are formed on a surface of the resisting member; each cover includes an elongated main portion and a fastening portion extending substantially perpendicularly from a first end of the elongated main portion; a notch for engaging with one of the protrusions of the resisting member is defined in the fastening portion. 17. The retention assembly as claimed in claim 16, wherein the platform has a plurality of hooking members; each cover further comprises a tab extending from a second end of the elongated main portion opposite to the fastening portion; each of the hooking members of the platform is configured to engagingly receive the tab of a corresponding one of the covers.
