New description: . [New technical field] An adjustable table and chair structure is a combination of a screw and a gear assembly and a lifting screw to adjust the south of the table with one hand. The hand turns the front and rear knobs to adjust the table to the most comfortable position. [Prior Art] The adjustable table and chair structure is all adjusted in sections, and it is very inconvenient to use both hands to adjust. It is also the direction that the creator and the manufacturer involved in this design and manufacturing want to study and improve. . [New content] An adjustable table and chair structure consists of a table top, a rack, a lifting screw, a table front and rear knob, a linkage screw, a base rod, a foot pad, a seat telescopic rod, a lifting handle, a seat lift rod, It consists of a gear assembly, a seat and a hook. The table can be easily adjusted to the appropriate position by turning the lifting handle and the front and rear knobs with one hand, so that users of different heights can use it. [Embodiment] An adjustable table and chair structure is composed of a table top (1), a rack (3), a lifting screw (2), a front and rear knob (4), a linkage screw (5), a base rod (6), The foot pad (7), the seat telescopic rod (8), the lifting handle (12), the seat lifting rod (9), the gear assembly (13), the seat (1 inch), the hook (11) . 5 M342803 can be combined with the lifting gear (12) and the linkage screw (5) by the gear assembly (13), so that the lifting screw (2) can adjust the height of the table top (1) up and down, and then the table front and rear knobs and teeth racks (3) Let the desktop (1) move back and forth. The seat (1〇) can be telescopically adjusted to the distance between the seat (1〇) and the table top (1) by the seat telescopic rod (8) combined with the base rod (6). In this way, the user can rotate the lifting handle (12) and the front and rear knobs (4) of the table to adjust the table top (1) to the appropriate position, so that users of different heights can use it.
