[0056] In order to ensure aesthetics, an outer peripheral plate 24 is also rotatably connected to the outside of the bottom plate 1. During use, the end with a smaller diameter of the outer peripheral plate 24 is used upward. Specifically:

[0057] An outer peripheral plate 24 is also rotatably connected to the outside of the bottom plate 1. A plurality of balls 25 are equidistantly arranged along the circumferential direction of the outer circle of the top of the bottom plate 1. The balls 25 are in contact with the inner wall of the outer peripheral plate 24; thus, it is prevented that the horizontal shaking of the outer peripheral plate 24 during use causes contact with the bottom plate 1 and causes damage. The balls 25 are arranged in a semi-sunken manner.

[0058] The outer edge of the bottom plate 1 is also evenly connected with multiple groups of fixing blocks 30. An adjustable foot 31 that can be adjusted vertically is provided inside the fixing block 30. A limiting wheel 29 is connected to the outer end of the adjustable foot 31. The limiting wheel 29 can be a bearing wheel or other rotatable rolling structures for use. The inner wall of the outer peripheral plate 24 is concave with an inner wall groove 26 that is arc-shaped to cooperate with the limiting wheel 29. In specific use, there are four groups of both the inner wall groove 26 and the limiting wheel 29, and they are evenly distributed for use. The installation is completed through the above structure, so as to change the shape of the table body. Before use, rotate the outer peripheral plate 24 to control it to move downward. At this time, the deformation of the table body is carried out through the above operation. After use, reverse the outer peripheral plate 24 to reset it.

[0059] More specifically, as Figures 8-9 shown, an adjustment groove 28 is provided in the middle of the fixing block 30. A threaded rod is rotatably connected between the top and the bottom of the adjustment groove 28. The adjustable foot 31 is threadedly sleeved on the threaded rod. Cover plates are provided at both the upper end and the lower end of the threaded rod. The lower end of the threaded rod actually penetrates the bottom wall of the bottom plate 1. By twisting the knob at the lower end of the threaded rod, the rotation of the threaded rod can be controlled, so as to control the movement of the adjustable foot 31 along the opening of the adjustment groove through threaded cooperation.
