The connecting portion 3202 is fixed to the support column 300, the upper end surface of the connecting portion 3202 is provided with the upper abutting portion 3200, and the lower end surface of the connecting portion 3204 is provided with the lower abutting portion 3204. The lower stopping part 3204 is used to prevent the supporting column 300 from turning upwards.

In addition, as shown in fig. 13B, the first position-limiting portion 320 of the present embodiment is provided with a positioning portion 321, and the first position-limiting member 500 of the present embodiment is inserted into the locking portion 212 and then fixed to the positioning portion 321.

To sum up, the table body folding structure of the present invention utilizes the inclined supporting column 300 and the movable seat 400 to move in opposite directions when the table body is stored, so that the whole center of gravity of the table body is located in the supporting column 300, thereby reducing the occurrence of the overturning situation when the table body is folded or unfolded. In addition, the utility model can also drive the base 200, the supporting column 300 and the movable seat 400 to be linked through the arrangement of the linking member 700 and the eccentric wheel 910 and other related linking structures, so that the supporting column 300 and the movable seat 400 can move reversely when the table body is folded or unfolded, thereby increasing the convenience of the table body in use. Finally, the present invention can further increase the setting of the electric push rod 810 or the driving device 820 to drive the movement of the linkage 700, so as to allow the user to use the table more conveniently.
