A fixing device for securing a circuit board to a plate member includes a spacer, a nut member, and a fastener. A coupling hole is defined through the spacer. A female thread is formed on a part of an interior surface of the coupling hole at an end thereof. A nut member comprises a pressing portion and a coupling portion extending from the pressing portion. A male thread is formed on a part of an exterior surface of the coupling portion at a free end thereof, corresponding to the female thread of the coupling hole of the spacer such that the coupling portion is capable of being movably retained in the coupling hole. A threaded hole is defined in the nut member. A fastener includes a head and a threaded rod extending from the head for being screwed in the threaded hole of the nut member.

What is claimed is: 1. A fixing device for securing a circuit board to a plate member, comprising: a spacer being located between the circuit board and the plate member and defining a coupling hole therethrough, a female thread being formed on a part of an interior surface of the coupling hole at an end thereof; a nut member comprising a pressing portion and a coupling portion extending from the pressing portion, a male thread being formed on a part of an exterior surface of the coupling portion at a free end thereof, corresponding to the female thread of the coupling hole of the spacer, a threaded hole being defined in the nut member, the coupling portion movably retained in the coupling hole of the spacer after the free end of the coupling portion with the male thread being screwed through the end of the coupling hole with the female thread, the pressing portion and the spacer cooperatively configured for sandwiching the plate member therebetween; and a fastener including a head and a threaded rod extending from the head for being screwed in the threaded hole of the nut member, the head being sandwiched the circuit board with the spacer; wherein the height of the remaining unthreaded part of the exterior surface of the coupling portion is greater than the height of the threaded part of the interior surface of the coupling hole, so that the coupling portion can be moved to allow the pressing portion to be adjacent the spacer as the threaded rod of the fastener is screwed into the threaded hole of the nut member. 2. The fixing device as described in claim 1, wherein the spacer takes an inverted "T" in profile, and when the coupling portion of the nut member is retained in the coupling hole of the spacer and the threaded rod of the fastener is engaged in the threaded hole of the nut member, a smaller end of the spacer is adjacent the head of the fastener and a bigger end thereof is adjacent the pressing portion of the nut member. 3. The fixing device as described in claim 1, wherein the spacer comprises a supporting post and a stopping portion formed at an end of the supporting post, and when the coupling portion of the nut member is retained in the coupling hole of the spacer and the threaded rod of the fastener is engaged in the threaded hole of the nut member, the supporting post of the spacer is adjacent the head of the fastener and the stopping portion thereof is adjacent the pressing portion of the nut member. 4. The fixing device as described in claim 3, wherein an outer diameter of the stopping portion of the spacer is generally equal to an outer diameter of the pressing portion of the nut member. 5. The fixing device as described in claim 3, wherein an outer diameter of the stopping portion of the spacer is greater than an outer diameter of the supporting post of the spacer. 6. The fixing device as described in claim 1, wherein a shoulder is formed at a junction between the head of the fastener and the threaded rod of the fastener, configured to press the circuit board against the spacer. 7. The fixing device as described in claim 1, wherein the height of the remaining unthreaded part of the interior surface of the coupling hole is greater than the height of the threaded part of the exterior surface of the coupling portion. 8. A mounting assembly comprising: a plate member defining at least one inserting hole therein; a circuit board defining at least one aligning hole corresponding to said at least one inserting hole; a spacer being sandwiched between the plate member and the circuit board, the spacer comprising a supporting post supporting a portion of the circuit board surrounding said at least one aligning hole, and a stopping portion seated on a portion of the plate member surrounding said at least one inserting hole, a coupling hole being defined through the spacer, a female thread being formed on a part of an interior surface of the coupling hole at the stopping portion; a nut member comprising a pressing portion abutting against a surface of the plate member away from the circuit board, and a coupling portion extending from the pressing portion, a male thread being formed at a free end of the coupling portion, the coupling portion being passed through said at least one inserting hole of the plate member and screwed through the threaded part of the coupling hole of the spacer and retained in the coupling hole of the spacer, a threaded hole being defined in the nut member; and a fastener including a head abutting against a surface of the circuit board away from the plate member, and a threaded rod extending from the head and being inserted through said at least one aligning hole of the circuit board and screwed in the threaded hole of the nut member, thereby firmly securing the circuit board to a plate member; wherein as the threaded rod of the fastener is screwed into the threaded hole of the nut member, the coupling portion is urged to move within the coupling hole to allow the pressing portion to be adjacent the spacer, thereby the threaded part of the exterior surface of the coupling portion is spaced from the threaded part of the interior surface of the coupling hole. 9. The mounting assembly as described in claim 8, wherein an inner diameter of the inserting hole of the plate member is greater than an outer diameter of the coupling portion of the nut member and smaller than outer diameters of the pressing portion of the nut member and the stopping portion of the spacer. 10. The mounting assembly as described in claim 9, wherein an outer diameter of the supporting post of the spacer is greater than an inner diameter of said at least aligning hole of the circuit board. 11. The mounting assembly as described in claim 10, wherein the outer diameter of the stopping portion of the spacer is greater than the out diameter the supporting post thereof. 12. The mounting assembly as described in claim 10, wherein the outer diameter of the stopping portion of the spacer is generally equal to the outer diameter of the pressing portion of the nut member. 13. The mounting assembly as described in claim 8, wherein an outer diameter of the coupling portion of the nut member is smaller than an inner diameter of the coupling hole of the spacer. 14. The mounting assembly as described in claim 8, wherein the height of the remaining unthreaded part of the exterior surface of the coupling portion is greater than the height of the threaded part of the interior surface of the coupling hole.
