[0026] Embodiment 2

[0027] As Figure 1-Figure 5 shown in the figure, an armrest adjustment mechanism 7 is provided on the base frame 1. The armrest adjustment mechanism 7 includes an armrest mounting frame 701. The armrest mounting frame 701 includes three connecting rods that are rotatably connected end to end. The armrest mounting frame 701 is in a structure shaped like a "冖". Both ends of the armrest mounting frame 701 are rotatably connected to the inner side of the base frame 1. The armrest adjustment mechanism 7 can adjust the armrest mounting frame 701, so as to make the armrests move forward synchronously after the sofa is laid down, facilitating the user to support the arms after the sofa is adjusted. An armrest drive plate 702 is rotatably connected to the inner side of the armrest mounting frame 701. The armrest drive plate 702 is rotatably connected to the moving frame 3. When the moving frame 3 moves, it can drive the armrest adjustment plate to be adjusted synchronously.

[0028] When the stretch sofa with zero wall leaning function of the utility model is in use, the electric push rod 4 is started and the sofa is adjusted. When the sofa is adjusted from a sitting position to a leisure position, the electric push rod 4 is started and the driving frame 5 is pushed outward to a set length. The driving frame 5 drives the stretch fixing plates 601 on both sides to be adjusted synchronously. The middle and lower parts of the stretch plate 2 are rotatably connected with the stretch adjustment plate 1 602, and at the same time, the end of the stretch plate 2 is rotatably connected with the stretch adjustment plate 2 603. When the stretch plate 2 moves with the driving frame 5, the angle between the stretch plate 2 and the stretch adjustment plate 2 603 is adjusted from an acute angle to an obtuse angle. At the same time, the angle between the stretch plate 2 and the stretch adjustment plate 1 602 changes less. Therefore, the end of the stretch adjustment plate 2 603 moves in an arc shape around the end of the stretch adjustment plate 1 602, and the stretch support plate 604 and the foot pedal 605 at the end are flipped. At the same time, when the driving frame 5 moves, the drive frame 5 rotates the stretch fixing plate 601 outward, and the electric push rod 4 When the sofa is adjusted from a leisure posture to a lying posture, the electric push rod 4 continues to drive the driving frame 5 to move, and the driving frame 5 drives the moving frame 3 to move forward by extending the fixing plate 601, and the moving frame 3 then drives the backrest mounting frame 203 to move forward synchronously through the backrest driving plate 204. At the same time, the end of the backrest mounting frame 203 close to the base frame 1 is restricted by the backrest connecting plate 202. At the same time, since the backrest mounting frame 203 moves with the moving frame 3, the backrest mounting frame 203 rotates toward the base frame 1, so that the backrest mounting frame 203 moves outward and rotates inward. When the moving frame 3 moves, the moving frame 3 drives the armrest mounting frame 701 to move through the armrest driving plate 702, so that the armrest mounting frame 701 is adjusted from an inwardly inclined state to an outwardly inclined state.
