When the release mechanism is pressed and the pressing force is not applied, the lifting rod 421 extends, and the object placing plate 41 rises; when the release mechanism is depressed, and a downward force is applied, the object plate 41 is lowered. The gas spring and corresponding release mechanism are of known construction and are not deployed here.

The principle of the embodiment of the present embodiment is as follows:

when the tea table 4 is located at the front side of the sofa body 1, the roller 541 is embedded in the groove 651 by the pressure spring 542 and abuts against the inner wall of the groove 651. At this time, the tea table 4 is pushed horizontally, and the tea table 4 only moves horizontally along the front side of the sofa body 1 and does not swing due to the limitation of the roller 541.

When the tea table 4 moves to the left side or the right side edge of the sofa body 1, the carrier 5 is blocked by the block 34, and the tea table 4 cannot translate; at this time, the guiding column 33 is located at the opening of the sliding track 67, and the tea table 4 is swung by continuously pushing the tea table 4, so that the guiding column 33 moves along the sliding track 67 relative to the rotating plate 6 and finally abuts against the side wall of the supporting portion 65, and at this time, the tea table 4 is also swung to the position corresponding to the side end of the sofa body 1.

If the slide way 67 is replaced by an oval slide way 67 or another shape of slide way 67, and the blocking of the stopper 34 is correspondingly cancelled. When the rotary board 6 touches the guiding column 33, the rotary board 6 is forced to change from moving to swinging by the guiding column 33, and the tea table 4 is correspondingly swung.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
