1. A device for fastening a dust box to a cyclone vacuum cleaner comprising:an accommodating part having a space in a body of the cyclone vacuum cleaner, wherein at least one sloped projection is formed on the accommodating part;a dust box mounted in the accommodating part selectively, for collecting various foreign matters separated from air, wherein at least one dust box sloped surface is formed on the dust box at a position corresponding to the position of the sloped projection on the accommodating part, and wherein movement of the dust box relative to the accommodating part causes the dust box sloped surface to bear against the sloped projection to thereby cause the dust box to move in up and down directions.2. A device as claimed in claim 1, wherein the at least one sloped projection is located on a bottom of the accommodating part, and wherein the sloped projection extends along a direction of coupling, and wherein the at least one dust box sloped surface is located within a recess for accommodating the sloped projection.3. A device as claimed in claim 2, wherein the at least one dust box sloped surface in the recess reaches a height that is approximately the same with a bottom surface of the dust box.4. A device as claimed in claim 2, wherein the at least one sloped projection is formed at a side of the bottom of the accommodating part, wherein the recess is formed such that the at least one sloped projection can be inserted in the recess when the dust box is fully set in the accommodating part, and wherein the recess helps to guide movement of the dust box relative to the accommodating part.5. A device as claimed in claim 1, wherein both the dust box and inside space of the accommodating part are substantially cylindrical so that both are matched.6. A device as claimed in claim 5, wherein the at least one sloped projection and the at least one dust box sloped surface extend in a circumferential direction of the accommodating part and dust box, respectively, such that rotation of the dust box relative to the accommodating part causes up and down movement of the dust box relative to the accommodating part.7. A device as claimed in claim 6, where the at least one sloped projection comprises a plurality of sloped projections that are equally spaced around a circumference of the accommodating part, and wherein the at least one dust box sloped surface comprises a plurality of sloped surfaces that are spaced evenly around a circumference of the dust box.8. A device as claimed in claim 7, wherein the plurality of dust box sloped surfaces are located in recesses formed on the dust box.9. A device as claimed in claim 8, wherein a recess is formed across a diameter of the dust box to allow the dust box to be inserted into the accommodating part past a sloped projection located at a front of the accommodating part.10. A device as claimed in claim 6, wherein a shoulder is formed on the at least one sloped projection and a corresponding shoulder is formed on the at least one dust box sloped surface, and wherein the shoulders are configured to bear against one another to limit rotation of the dust box relative to the accommodating part.11. A device as claimed in claim 1, wherein the accommodating part includes an elastically mounted bottom for permitting up and down direction movements along an inside of the accommodating part.12. A device as claimed in claim 1, further comprising a rim around a top surface of the accommodating part for covering a top circumference of the dust box, for closing a gap formed between the top surface of the accommodating part and the top circumference of the dust box when the dust box is fastened to the accommodating part.13. A vacuum cleaner comprising:an accommodating part forming a space in a body of the cyclone vacuum cleaner, wherein the accommodating part accommodates a dust box;a moving part provided to a bottom portion of the accommodating part and having a first sloped portion, for selectively fastening the dust box to the accommodating part by moving in an upward direction and exerting a force to a bottom of the dust box; anda guide part having a second sloped portion corresponding to the first sloped portion, wherein the moving part and the guide part move relative to each other and the first sloped portion and the second sloped portion bear against each other such that the moving part moves in an upward or downward direction.14. The vacuum cleaner of claim 13, wherein the moving part is provided on the guide part.15. The vacuum cleaner of claim 14, wherein the first sloped portion comprises at least one first sloped surface formed on a bottom of the moving part, and the second sloped portion comprises at least one second sloped surface formed on a top surface of the guide part.16. The vacuum cleaner of claim 15, wherein at least one recess having the at least one first sloped surface is formed on the bottom of the moving part.17. The vacuum cleaner of claim 13, wherein the moving part and the guide part rotate relative to each other such that the moving part moves in an upward or downward direction.18. The vacuum cleaner of claim 17, wherein the moving part is provided on the guide part.19. The vacuum cleaner of claim 18, wherein the first sloped portion comprises at least one first sloped surface on a bottom of the moving part and tapering in a circumferential direction, and the second sloped portion comprises at least one second sloped surface formed on a top surface of the guide part and tapering in a circumferential direction.20. The vacuum cleaner of claim 19, wherein at least one recess having the at least one first sloped surface is formed on the bottom of the moving part.21. The vacuum cleaner of claim 13, wherein the moving part is provided on the guide part and the guide part is elastically supported by a spring.22. The vacuum cleaner of claim 13, further comprising a handling lever provided on an outer side of the moving part so as to handle the movement of the moving part.23. A vacuum cleaner comprising:an accommodating part forming a space in a body of the cyclone vacuum cleaner, wherein the accommodating part accommodates a dust box;a moving part provided to a bottom portion of the accommodating part and having at least one first sloped surface formed on a bottom of the moving part, for selectively fastening the dust box to the accommodating part by moving in an upward direction and exerting a force to a bottom of the dust box;a guide part provided under the moving part and having at least one second sloped surface formed on a top surface of the guide part, the at least one second sloped surface corresponding to the at least one first sloped surface, respectively, wherein the moving part and the guide part move relative to each other and the at least one first sloped surface and the at least one second sloped surface bear against each other such that the moving part moves in an upward or downward direction; anda handling lever connected to one of the moving part and the guide part so as to handle the movement of the moving part.24. The vacuum cleaner of claim 23, wherein the moving part and the guide part rotate relative to each other such that the moving part moves in an upward or downward direction.25. The vacuum cleaner of claim 24, wherein the at least one first sloped surface tapers in a circumferential direction, and the at least one second sloped surface tapers in a circumferential direction.26.
