[0026] The tabletop 10 has rounded corners, and each of the four corners has a grip hole 20 that passes through the tabletop 10.

[0027] Several sponge sleeves 21 are respectively fitted onto the grip bar of the grip hole 20;

[0028] Four lifting columns 30 are respectively installed at the four corners of the lower surface of the tabletop 10;

[0029] Four support tubes 40 are slidably sleeved on four lifting columns 30 respectively;

[0030] The connecting plate 60 is radiating in four directions, and its four ends are fixedly connected to the outer walls of the four support pipes 40 respectively.

[0031] The support tube 40 is provided with a first positioning component 70 or a second positioning component 80 for fixing the lifting column 30 to the support tube 40.

[0032] The first positioning component 70 includes several vertically arranged limiting grooves 71 disposed on the lifting column 30. The side wall of the support tube 40 has a first through hole 72 corresponding to the position of one of the limiting grooves 71. A positioning ring 74 is disposed in the U-shaped groove of the connecting plate 60. The positioning ring 74 has a sliding rod 73 that passes through the positioning ring 74. The rod 73 passes through the first through hole 72 and extends into the limiting groove 71. A spring 75 is slidably sleeved on the rod 73. One end of the spring 75 is connected to the positioning ring 74 and the other end is connected to the end of the rod 73. A first limiting bolt 76 is threadedly connected to the connecting plate 60 to restrict the rod 73 from moving away from the lifting column 30.

[0033] The second positioning component 80 includes a positioning groove 81 disposed on the outer wall of the lifting column 30, a vertical rack 82 disposed in the positioning groove 81, a second through hole 83 on the support tube 40 corresponding to the position of the positioning groove 81, a threaded sleeve 86 disposed in the U-shaped groove of the connecting plate 60, a threaded rod 85 connected to the threaded sleeve 86 by threads, a toothed block 84 rotatably disposed at the end of the threaded rod 85, the toothed block 84 passing through the second through hole 83 and meshing with the rack 82, and a second limiting bolt 87 connected to the connecting plate 60 by threads to restrict the threaded rod 85 from moving away from the lifting column 30;

[0034] Four corrugated pipes 50 are slidably sleeved on the lifting column 30 and the support pipe 40 respectively.
