1. A hinge structure, comprising: a mounting base member, said mounting base member comprising a base wall, an upright wall vertically upwardly extended from a top surface of said base wall and a screw hole located in said upright wall, a rotary knob threaded into said screw hole, a plurality of female hinge shafts fixedly mounted at the top surface of said base wall and surrounded by said upright wall, and a male hinge shaft rotatably inserted through said female hinge shafts, wherein: said male hinge shaft comprises a cylindrical shaft body rotatably inserted through each said female hinge shaft, a connection portion located at one end of said cylindrical shaft body and disposed adjacent to said upright wall; said rotary knob comprises a threaded shank threaded into said screw hole, an actuation portion located at one end of said threaded shank and coupled to said connection portion of said male hinge shaft in such a manner that rotating said rotary knob to move said threaded shank in direction toward or away from said mounting base member causes said male hinge shaft to be moved axially in one of two reversed directions. 2. The hinge structure as claimed in claim 1, wherein each said female hinge shaft comprises a tubular shaft body defining therein an axially extending shaft chamber for the passing of said cylindrical shaft body of said male hinge shaft, and a positioning portion formed integral with the periphery of said tubular shaft body and fixedly mounted at the top surface of said base wall. 3. The hinge structure as claimed in claim 1, wherein said rotary knob further comprises a receiving trough defined in said actuation portion and adapted for receiving said connection portion of said male hinge shaft, and a protruding portion formed integral with one end of said actuation portion; said male hinge shaft further comprises a position-limit groove extending around the periphery thereof between said connection portion and said cylindrical shaft body and coupled with said protruding portion of said rotary knob. 4. The hinge structure as claimed in claim 1, wherein said male hinge shaft further comprises a mounting portion located at an opposite end of said cylindrical shaft body remote from said connection portion and disposed outside said female hinge shafts. 5. A hinge structure, comprising: a mounting base member, said mounting base member comprising a base wall, an upright wall vertically upwardly extended from a top surface of said base wall and a screw hole located in said upright wall, a rotary knob threaded into said screw hole, a plurality of female hinge shafts fixedly mounted at the top surface of said base wall and surrounded by said upright wall, and a male hinge shaft rotatably inserted through said female hinge shafts, wherein: said male hinge shaft comprises a cylindrical shaft body inserted through the shaft chamber of each said female hinge shaft, said cylindrical shaft body comprising a non-circular coupling hole axially extending through two opposing ends thereof, and a transmission rod axially slidably inserted through said non-circular coupling hole of said cylindrical shaft body, said transmission rod comprising a non-circular rod body inserted through said non-circular coupling hole of said cylindrical shaft body for allowing said cylindrical shaft body to be rotated with said transmission rod, a connection portion located at one end of said non-circular rod body and disposed adjacent to one end of said upright wall; said rotary knob comprises a threaded shank threaded into said screw hole, an actuation portion located at one end of said threaded shank and coupled to said connection portion of said transmission rod of said male hinge shaft in such a manner that rotating said rotary knob to move said threaded shank in direction toward or away from said mounting base member causes said transmission rod of said male hinge shaft to be moved axially in one of two reversed directions. 6. The hinge structure as claimed in claim 5, wherein each said female hinge shaft comprises a tubular shaft body defining therein an axially extending shaft chamber for the passing of said cylindrical shaft body of said male hinge shaft, and a positioning portion formed integral with the periphery of said tubular shaft body and fixedly mounted at the top surface of said base wall. 7. The hinge structure as claimed in claim 5, wherein said rotary knob further comprises a receiving trough defined in said actuation portion and adapted for receiving said connection portion of said male hinge shaft, and a protruding portion formed integral with one end of said actuation portion; said transmission rod of said male hinge shaft further comprises a position-limit groove extending around the periphery thereof between said connection portion and said non-circular rod body and coupled with said protruding portion of said rotary knob. 8. The hinge structure as claimed in claim 5, wherein said transmission rod of said male hinge shaft further comprises a mounting portion located at an opposite end of said non-circular rod body remote from said connection portion and disposed outside said female hinge shafts.
