The support 15 base 10 is made of wood or metals and has one side on which a first post 101 is mounted. The first post 101 has an opposite end that forms a first rotary joint section 1010. The support base 10 can be arranged in a W-shape or a V-shape. The casters 11 are mounted to an opposite side of the support base 10 in a symmetric arrangement. The first desk board 12 has a surface that is 20 provided with a second rotary joint section 121 and an opposite surface that is 8 provided, in a symmetric manner and at an edge thereof, with a fourth rotary joint section 123 and a third rotary joint section 122. The first desk board 12 is provided with a platform 124 at an edge of the surface thereof In the instant embodiment, the first desk board 12 is rectangular in order to provide a 5 maximum deposition space. The second post 13 has an end that is provided with a fifth rotary joint section 131 that is rotatably jointed to the second rotary joint section 121 and an opposite end that is rotatably jointed to the first rotary joint section 1010. The first post 101 has a circumference around which an adjustment device 19 is formed. The second desk board 14 has a surface that 10 is provided with a retention board 141 and is provided, in a symmetric manner with respect to a circumference of two surfaces, with a fifth rotary joint section 142 and a seventh rotary joint section 143. The second desk board 14 is slightly smaller than the first desk board 12 in order to enhance overall aesthetics of the desk structure 1. In the instant embodiment, the second desk 15 board 14 is rectangular in order to provide a maximum deposition space. The first connection bar 15 has an end forming an eighth rotary joint section 152 that is rotatably jointed to the fifth rotary joint section 142 and an opposite end forming a ninth rotary joint section 151 that is rotatably jointed to the third rotary joint section 122. The first connection bar 15 is necessarily made of a 20 metal material in order to provide a sufficient strength to support the second 9 desk board 14. The second connection bar 16 has an end forming a tenth rotary joint section 162 that is rotatably jointed to the seventh rotary joint section 143 and an opposite end forming an eleventh rotary joint section 161 that is rotatably jointed to the fourth rotary joint section 123. The second 5 connection bar 16 is made of the same material as that of the first connection bar 15. The third desk board 18 has a surface having two ends respectively and movable on surface of the first desk board 12. The third desk board 18 is rectangular in order to provide a maximum deposition space. The two rotary coupling plates 17 each have two ends respectively fixed to the same surface 10 of the third desk board 18 and the same surface of the first desk board 12. Since the two rotary coupling plates 17 are respectively fixed to surfaces of the third desk board 18 and the first desk board 12 so that the third desk board 18 and the first desk board 12 are allowed to have surfaces thereof connected to be movable toward each other (where the third desk board 18 has a size 15 corresponding to a size of the platform 124). Referring to FIGS. 2 and 4, which are respectively a perspective view of the preferred embodiment of the present invention and a schematic view illustrating an operation of the preferred embodiment of the present invention, the second desk board 14 is normally positioned close to the first desk board 20 12 and in use, the second desk board 14 is operated to move upward so as to 10 rotate the second desk board 14 to a predetermined location, where a fictional torque generated by the ninth rotary joint section 151 and the eighth rotary joint section 152 of the first connection bar 15 and the eleventh rotary joint section 161 and the tenth rotary joint section 162 of the second connection bar 5 16 that are respectively and rotatably jointed to the third rotary joint section 122, the fourth rotary joint section 123, the fifth rotary joint section 142, and the seventh rotary joint section 143 helps set an angle to achieve inclination at an angle or parallel arrangement thereof with respect to a reference defined by the first desk board 12 and thus prevents the second desk board 14 from 10 undesired rotation. Further, the retention board 141 on a surface of the second desk board 14 is set upward for use. Referring to FIGS. 2 and 5, which are respectively a perspective view of the preferred embodiment of the present invention and another schematic view illustrating the operation of the preferred embodiment of the present invention, 15 when the desk structure 1 is not in use, the second rotary joint section 121 of a surface of the first desk board 12 and the fifth rotary joint section 131 of the second post 13 may be set to form means that provide fictional torques for being fixed at an angle and also allows for rotation so that the first desk board 12 and the second post 13 are changed from the originally set perpendicular 20 arrangement to a parallel arrangement (as shown in FIG. 5), whereby the I I space occupied by the first desk board 12 is reduced. Further, the third desk board 18 is rotatable by means of the two rotary coupling plates 17 to stack on the platform 124 on a surface of the first desk board 12 (as shown in FIG. 5A), whereby the space occupied by the desk structure 1 is reduced. Further, 5 since the support base 10 is structured in a W-shape or a V-shape, the desk structure 1 can be densely arranged in order to increase the storage space when put into storage. Referring to FIGS. 2, 6, and 7, which are respectively a perspective view of the preferred embodiment of the present invention, a perspective view 10 showing another preferred embodiment of the present invention, and a schematic view illustrating an operation of the another preferred embodiment of the present invention, the first connection bar 15 and the second connection bar 16 can be substituted by two pairs of rotary coupling plates 17. The two pairs of rotary coupling plates 17 each have an end fixed to an edge of a 15 surface of the first desk board 12 and an opposite end fixed to an edge of a surface of the second desk board 14, so that the second desk board 14 is rotatable upwards, in a direction opposite to the first desk board 12 by means of the pairs of rotary coupling plate 17, to a predetermined location, and the retention board 141 is arranged to show at an edge of an opposite surface of 20 the second desk board 14. The retention board 141 is rotatable in a direction 12 opposite to the second desk board 14 to be positioned on a surface of the first desk board 12 so that a surface of the retention board 141 may support a computer without falling.
