Description of the invention: [Technical field to which the invention pertains] - The present invention relates to a fastening device. [Prior Art] • In actual production or life, it is often necessary to fasten two or more 'plates together for the fixing of related components. The contact between the two plates is usually achieved by means of screws. The contact between the non-contact plates and the body is achieved by means of specific fastening devices, such as fastening the electric and brain boards to the computer case. Since the electronic components on the motherboard need to occupy a certain space, the motherboard cannot be directly attached to the computer chassis, and a certain gap is required. The fastening device of the computer motherboard usually comprises a screw, a copper column and a washer; the outer wall of the copper column is stepped, a screw hole is formed at the thicker end, and an annular groove is provided near the end of the thin end; the washer Slightly elastic, with a convex ring on the inner side wall. When using Φ, pass the screw through the perforation of the computer motherboard, lock it into the screw hole of the copper column, pass the thin end of the copper column through the perforation of the computer case, and snap the collar of the washer into the ring of the copper column. Slots to secure the motherboard to the computer case. However, since the combination of the gasket and the copper post is liable to leave a gap, and the gasket is elastic and easily deformed, the fixing of the main board is not tight enough, and sway or even shift may occur. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a tightly coupled fastening 7 200837534 device. A fastening device for fastening two plates respectively provided with a perforation, the fastening device comprises a screw, a support column and a fixing member, the screw comprises a screw head and a screw, the fixing member comprises a a pressing portion and a fixing portion, and a screw hole is formed along the axial direction of the fixing portion, the supporting column defines a through hole, and the fixing portion of the fixing member passes through the through hole of one of the plates and extends into the supporting column a hole passing through the perforation of the other plate and screwed into the screw hole of the fixing member, thereby clamping the two plates to the pressing portion of the fixing member and the supporting column, the supporting column and the Between the screw heads. Compared with the prior art, the screw of the screw is directly screwed into the screw hole of the fixing member, and the threads of the two are tightly coupled, so that the two plates can be firmly connected together. 1 and 2, a preferred embodiment of the fastening device of the present invention includes a screw 20, a support post 40 and a fixing member 60 for fastening a computer motherboard 80 to a sheet metal. 90. The screw 20 includes a screw head 22 and a screw 24 extending perpendicularly from the screw head 22; an end of the screw head 22 adjacent to the screw 24 is provided with an outwardly convex circular pressing portion 222, and the diameter of the pressing portion 222 is larger than the screw 24 diameter of. The support column 40 has a substantially convex shape, and the main body thereof is a cylindrical support portion 42. One end portion of the support portion 42 is provided with a cylindrical chassis 44 having a diameter larger than the branch 8 200837534 «the support portion 42; the center of the support column 40 is opened. The through hole 46 of the support portion 42 and the chassis 44 is penetrated, and the through hole 46 is provided with an internal thread on the side wall of one end of the chassis 44. The fixing member 60 includes a cylindrical fixing portion 62 and a pressing portion 64 provided at the end of the fixing portion 62. The pressing portion 64 has a diameter larger than the diameter of the fixing portion 62, and the fixing portion 62 is provided with an external thread at one end away from the pressing portion 64. The fixing member 60 defines a screw hole 66 along the axial direction of the fixing portion 62 and the pressing portion 64. 10 A through hole 82 is formed in the main board 80 of the computer. The diameter of the through hole 82 is such that the screw 24 of the screw 20 can pass through. A perforation 92 is formed in the sheet metal 90. The diameter of the perforation 92 is larger than the diameter of the fixing portion 62 of the fixing member 60, and is smaller than the diameter of the pressing portion 64 of the fixing member 60 and the chassis 44 of the support post 40. Referring to FIG. 3, in use, the fixing portion 62 of the fixing member 60 is passed through the through hole 92 of the sheet metal 90, and then screwed into the through hole φ 46 of the support post 40 until the external thread of the fixing member 60 is screwed through the through hole 46. The internal thread is configured to movably couple the fixing member 60 and the support post 40 to different sides of the sheet metal 90. At this time, the sheet metal 90 is not clamped by the pressing portion 64 of the fixing member 60 and the chassis 44 of the support post 40. The diameter of the perforation 92 of the 90 is larger than the diameter of the fixing portion 62 of the fixing member 60, and the fixing member 60 and the support post 40 can be appropriately adjusted in position on the sheet metal 90. The screw 24 of the screw 20 is passed through the through hole 82 of the computer main board 80, and the position of the fixing member 60 and the support post 40 on the sheet metal 90 is adjusted, so that the screw 24 of the screw 20 is threaded into and screwed to the screw hole 66 of the fixing member 60. In 200837534, during the tightening of the screw 20, the pressing portion 64 of the fixing member 60 gradually approaches the chassis 44 of the support post 40 until the sheet metal 90 is clamped, at which time the fixing member 60 and the support post 40 are on the sheet metal 90. The position can no longer be changed, and the computer main board 80 is clamped between the pressing portion 222 of the screw 20 and the support portion 42 of the support post 40 to be fastened with the sheet metal 90. _ fastening of different computer main board 80 and sheet metal 90 may be selected according to actual conditions, one or more fastening devices of the present invention, since the diameter of the perforation 92 of the sheet metal 90 is larger than the diameter of the fixing portion 62 of the fixing member 60, The present invention can still be used when the perforations 82 of the computer main board 80 are slightly different from the predetermined positions. Of course, the invention is equally applicable to the fastening of other panels. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations of the present invention in the spirit of the present invention are intended to be included in the following claims.
