[0013] Preferably, part of the adapter seat is embedded in the small base plate, and the adapter seat and the two sides of the small base plate are provided with gaps.

[0014] The setting provides the gaps, thereby facilitating the swing of the small base plate and reserving sufficient space for the swing of the small base plate.

[0015] Preferably, the bottom of the adapter seat is provided with a chair leg connecting column.

[0016] The setting facilitates the connection between the base plate and the chair leg through the action of the chair leg connecting column.

[0017] The utility model discloses the beneficial effect is: convenient to use, the structure is exquisite, can satisfy the use of seat, can make the function have left and right swing function, thereby facilitating the taking, picking of article, it has practicality and the universality of use.
