The following briefly describes the usage principle of the present invention.

The driving control box 22 on the bottom cabinet 16 is started to rotate the driving gear 21, the spiral thrust rotary disc 9 is driven to rotate through the gear ring 11, through the matching of the rotary disc bearing base 12 and the substrate rotary disc bearing 14, the spiral thrust rotary disc 9 performs plane rotation around the central positioning shaft 13, the arc-shaped tracks (the lifting sliding plate track 10 and the flat sliding plate track 31) on the spiral thrust rotary disc 9 form displacement from front (back) to back (front) on the upper linear sliding plate guiding through groove 30, namely, the rolling bearing columns 32 inserted into the arc-shaped tracks are driven to move back and forth in the sliding plate guiding through groove 30, so that the lifting sliding plate 6 and the flat sliding plate 7 above are driven to move forwards (inwards retract) or backwards (outwards).

When 4 lifting sliding plate 6 and 4 smooth plate 7 retract to the center, every lifting sliding plate 6 all can lift to adjacent smooth plate 7's top, 8 piece together the sliding plate and hide totally in big desktop 4, do not influence the original space of placeeing of big desktop 4, and after outwards expanding, 4 lifting sliding plate 6 can be in the coplanar and splice the smooth extension desktop that constitutes the circumference and is greater than big desktop 4 with 4 smooth plate 7.

The lifting action of the lifting slide 6 is realized by a lifting slide rail 10 arranged on the helical thrust rotor 9. The track surface of the smooth plate track 31 on the spiral thrust turntable 9 is horizontal from front to back, so that the smooth plate 7 always moves back and forth on one plane. The front half part of the track surface of the lifting sliding plate track 10 is horizontal, the rear half part is a downward inclined surface, so that the moving track of the lifting sliding plate 6 is high in the front and low in the rear, when the lifting sliding plate 6 moves from the center to the front and outwards, the track of the front half part is level and stable and is higher than the adjacent flat sliding plate 7, when the lifting sliding plate moves to the downward inclined surface of the rear half part, namely the inclined downward guide groove 27 of the lifting sliding plate, each lifting sliding plate 6 sinks along with the track, and finally the lifting sliding plate and the adjacent flat sliding plate 7 are positioned on the same plane to be spliced into an extended desktop.

In the above-mentioned structural design, the adjustment of the respective rail heights of the lifting slider 6 and the leveling slider 7 can be achieved by a plurality of schemes, for example, one scheme is: the front half part of the track surface of the lifting sliding plate track 10 is the same as the track surface of the flat sliding plate track 31 in height (depth), the inclined lower guide groove 27 of the lifting sliding plate in the rear half part is lower than the flat sliding plate track 31, and the length of the rolling bearing column 32 supporting the lifting sliding plate 6 is longer than that of the rolling bearing column 32 supporting the flat sliding plate 7. The second scheme is that the front half part of the track surface of the lifting sliding plate track 10 is higher than the track surface of the smooth plate track 31, the tail end of the inclined lower guide groove 27 of the lifting sliding plate in the rear half part is positioned on the same plane with the smooth plate track 31, and the length of the rolling bearing column 32 supporting the lifting sliding plate 6 and the smooth plate 7 is the same.
