Since the elastic element 34 is a constant force spring, for example, the constant force spring has a function of offsetting the weight of the table top 10 when the constant force spring is elastically expanded and stretched, so that the user can operate the table top with less effort and smoothly adjust the height of the table top 10 even with only one hand. Furthermore, the side of the inner leg 32 has a plurality of positioning portions 322, so that the user can adjust the height of the table 10 according to the requirement, thereby achieving the effect of multi-stage adjustment.

Please refer to fig. 7, which is a schematic diagram of the positioning operation of the multi-stage lifting table of the present invention. After the user has adjusted the required height of the table 10, the pressing state of the movable pressing plate 21 is opened, that is, the movable pressing plate 21 is away from the lower surface of the table 10, after the movable pressing plate 21 is opened, the movable pressing plate 21 is linked with the operating wire 40 to be in the wire releasing state, at this time, the abutting portion 3321 of the adjusting member 332 abuts against a positioning position a among the positioning portions 322 to form the positioning state. By means of simple operation and labor-saving structure design, the utility model can effectively improve the convenience of use.

In another embodiment, the structural design of the present invention is suitable for a single table leg or a plurality of table legs. Taking two table legs as an example, as shown in fig. 2, when the number of the table leg assemblies 30 is more than two, the number of the operating wires 40 used is the same as the number of the table leg assemblies 30, and the operating control member 20 is connected to the same operating control member 20, and the operating control member 20 synchronously controls the actuating unit 33 to abut against a positioning position a of the positioning portions 322 to form a positioning state, so as to correspondingly adjust the height of the table 10. The operation principle is the same as above, and therefore, the description thereof is omitted. The structural design of synchronous control by using only one operation control member 20 not only has low manufacturing cost, but also can be more accurate in adjustment of lifting, and can overcome the problem of inclination of the table board 10 generated by the prior art.

Of course, except that the same operation control member 20 is used for positioning control, when the number of the table leg assemblies 30 is more than two, the number of the operation wires 40 and the number of the operation control members 20 used are the same as the number of the table leg assemblies 30; for example, a foot assembly 30 may be associated with an operating wire 40 in combination with the operating controls 20.
