On the contrary, the utility model discloses a when base 4 descends, the synchronous reverse rotation of base lift lead screw 612 is separately driven to the base lift motor 70 of four base lift drive arrangement 7, and base lift lead screw 612 drives base lift slider 613 and descends on guide rail stand 611 to drive whole base 4 and descend. When the base lifting slide 613 is lowered to touch the lower travel switch 774, the base lifting motor stops driving the base lifting slide 613 to descend. Therefore, the utility model discloses can control the base and go up and down to convenience of customers cleans the health, and the user of also being convenient for pushes table below with stool or dining table chair, improves indoor space utilization.

In a fourth example, as shown in fig. 28, the embodiment of the fourth example is similar to the embodiment of the second example, except that: the table lifting driving device 8 for driving the table to lift is not arranged in the embodiment, the table cannot lift, and the base of the embodiment is driven to lift only by the base lifting driving device 7.
