The driving mechanism can drive the rotating seat 3 to rotate around the lifting mechanism 2, and the furniture body can rotate with the rotating seat 3. The lifting mechanism 2 is provided with a mounting plate 4, and the mounting plate 4 is provided with a conductive slip ring 5 for connecting the furniture body. The stator end of the conductive slip ring 5 is fixed on the mounting plate 4, and the rotor end of the conductive slip ring 5 is connected to the furniture body. The furniture body is connected to the conductive slip ring 5 and the rotating seat 3 at the same time. When the furniture body rotates with the rotating seat 3, the conductive slip ring 5 can be used to supply power to the electrical equipment on the furniture body.

[0025] The utility model can realize the free lifting of furniture, and can adjust the height of furniture according to the actual needs of users, so as to adapt to different users; the utility model can also realize the free rotation of furniture, and can adjust the angle and orientation of furniture in space according to the actual needs of users, so as to increase the convenience of furniture use; in addition, the utility model adopts the design of conductive slip ring 5, so that the normal power supply of electrical equipment on the furniture body is not affected during the rotation of the furniture body.

[0026] In one embodiment, a connecting bearing is provided between the rotating seat 3 and the furniture body. The connecting bearing is a prior art. The furniture body can rotate by the friction torque generated by the connecting bearing. When the furniture body is acted upon by an external force, the furniture body generates an external resistance torque on the connecting bearing.
