What is claimed is: 1. An elevation-adjustable support structure comprising: a connecting member, said connecting member having a bottom end and a top end; a bottom hinge structure, said bottom hinge structure comprising two bottom brackets, and at least one shaft fastened to said bottom brackets and pivoted to the bottom end of said connecting member for allowing said connecting member to be turned about the at least one shaft of said bottom hinge structure between said two bottom brackets; a top hinge structure, said top hinge structure comprising two top brackets, and at least one shaft fastened to said top brackets and pivoted to the top end of said connecting member for allowing said connecting member to be turned about the at least one shaft of said top hinge structure between said two top brackets; and at least one linking mechanism, said at least one linking mechanism each comprising a top wheel respectively coupled between the top end of said connecting member and the top brackets of said top hinge structure, a bottom wheel respectively coupled between the bottom end of said connecting member and the bottom brackets of said bottom hinge structure, and a flexible belt member coupled between said top wheel and said bottom wheel for maintaining the angle of inclination of said top brackets upon a rotary motion of said connecting member relative to said top hinge structure and said bottom hinge structure. 2. The elevation-adjustable support structure as claimed in claim 1, wherein said connecting member comprises two top lugs and two bottom lugs respectively extended from said top end and said bottom end, said top lugs and said bottom lugs each having a pivot hole for receiving the at least one shaft of top hinge structure and the at least one shaft of said bottom hinge structure respectively. 3. The elevation-adjustable support structure as claimed in claim 1, wherein said bottom brackets are fastened to a base member; said top brackets are fastened to a top mount to support a supported member. 4. The elevation-adjustable support structure as claimed in claim 2, wherein said bottom hinge structure is comprised of two hinges, the two hinges of said bottom hinge structure each comprising one shaft of the at least one shaft of said bottom hinge structure, a first gasket, a second gasket, a ring lug at one of said bottom brackets, at least one spring washer, and an end piece member, the shaft of each hinge of said bottom hinge structure being inserted in an order through the pivot hole of one bottom lug of said connecting member, an associating first gasket, an associating second gasket, the ring lug of an associating bottom bracket, and an associating at least one spring washer, and then fastened up with an associating end piece member. 5. The elevation-adjustable support structure as claimed in claim 4, wherein each hinge of said bottom hinge structure further comprises a friction member mounted on the associating shaft between the associating bottom lug and the associating first gasket, said friction member having a pin inserted into a retaining hole in the associating bottom lug. 6. The elevation-adjustable support structure as claimed in claim 4, wherein the shaft of a first hinge of the two hinges of said bottom hinge structure is axially formed integral with the shaft of a second hinge structure of the two hinges; said bottom hinge structure further comprises a torsional spring sleeved onto the integrated shafts of the hinges of said bottom hinge structure, said torsional spring having two opposite ends respectively stopped at a groove at the bottom end of said connecting member and the surface of said base member that is fastened to said bottom brackets. 7. The elevation-adjustable support structure as claimed in claim 4, wherein the first gasket of each hinge of said bottom hinge structure has a protruding portion engaged in an arched notch at the associating bottom lug of said connecting member. 8. The elevation-adjustable support structure as claimed in claim 4, wherein the second gasket of each hinge of said bottom hinge structure is fixedly mounted in the ring lug of the associating bottom bracket, having at least one pin respectively inserted into a respective hole on the ring lug of the associating bottom bracket. 9. The elevation-adjustable support structure as claimed in claim 2, wherein said top hinge structure is comprised of two hinges, the two hinges of said top hinge structure each comprising one shaft of the at least one shaft of said top hinge structure, a first gasket, a second gasket, a ring lug at one of said top brackets, at least one spring washer, and an end piece member, the shaft of each hinge of said top hinge structure being inserted in an order through the pivot hole of one of said top lug of said connecting member, an associating first gasket, an associating second gasket, the ring lug of an associating top bracket, and an associating at least one spring washer, and then fastened up with an associating end piece member. 10. The elevation-adjustable support structure as claimed in claim 9, wherein each hinge of said top hinge structure further comprises a friction plate mounted on the associating shaft between the associating ring lug and the associating first gasket, the friction plate of each hinge of said top hinge structure having a pin inserted into a retaining groove in the associating ring lug. 11. The elevation-adjustable support structure as claimed in claim 9, wherein the first gasket of each hinge of said top hinge structure has a protruding portion engaged in an arched notch of the associating top bracket. 12. The elevation-adjustable support structure as claimed in claim 9, wherein each hinge of said top hinge structure further comprises a retaining ring and a locating ring connected between the shaft and top bracket of the respective hinge, said locating ring being fastened to the ring lug of the associating top hinge structure, said retaining ring having two protruding portions, said locating ring having two arched retaining grooves symmetrically disposed at two opposite sides; when said top brackets are turned with said top mount, each protruding portion of said retaining ring is moved over one retaining groove of said locating ring into the other retaining groove of said locating ring to hold said top mount in parallel to said base member. 13. The elevation-adjustable support structure as claimed in claim 1, wherein said top wheel and said bottom wheel each have a belt groove extending around the periphery thereof, and said belt member is an endless belt coupled to the belt groove of said top wheel and the belt groove of said bottom wheel. 14.
