[0033] It should be noted that, in the present invention, when the support baffle 5 is pulled out from the bottom of the bottom support plate 1, the sliding support plate 6 slides outward from the inside of the support storage box 7, and at the same time, the pull-out baffle 9 slides out from the inside of the armrest box 8, and the two ends of the support baffle 5 are limited by the pull-out baffle 9. One end of the pull-out baffle 9 is in contact with the armrest box 8 to ensure the stability of the sliding support plate 6. When the support desktop 11 needs to be adjusted to a horizontal state, the support desktop 11 is rotated from the folding storage cavity 10 to a horizontal state, and then the fixing screw 12 is rotated to a vertical state, and the lock is pulled. The rod 15 compresses the spring 16. When the locking rod 15 corresponds to the limiting hole of the rotating shaft 17, the restraint on the locking rod 15 is released. Under the elastic force of the spring 16, the locking rod 15 is inserted into the limiting hole of the rotating shaft 17 to fix the angle of the rotating shaft 17. At this time, the fixing screw 12 and the threaded tube 13 are in a vertical state. The threaded tube 13 is rotated to make the threaded tube 13 move downward on the outside of the fixing screw 12, so that the supporting table top 11 is supported by the contact between the threaded tube 13 and the ground. When the sofa is formed into a bed, the supporting table top 11 can be used as a bedside table.
