The surface of the first connecting rod 71 is movably connected to a roller 72. The surface of the first connecting rod 71 is movably connected to a second connecting rod 73. One end of the second connecting rod 73 away from the first connecting rod 71 is movably connected to a rotating shaft 74. The surface of the backrest iron frame 1 is movably connected to a footrest 8. The footrest 8 can achieve the effect of independently lifting and lowering the left and right legs with only a single motor 63, which not only reduces the overall weight of the product but also reduces the cost of the product. The reclining of the chair frame is linked with the leg lifting. At the same time, driven by one motor 63, the two legs can be alternately lifted and lowered, and the legs can be alternately lifted, and in cooperation with the independent telescoping of the left and right legs, the effect of relaxing the leg tendons is achieved.

[0024] Furthermore, one end of the linkage rod 5 is rotatably connected to the seat iron frame 3, and the other end of the linkage rod 5 is rotatably connected to the linkage U-shaped tube 2. The linkage rod 5 can rotate with the rotation between the seat iron frame 3 and the linkage U-shaped tube 2.

[0025] Furthermore, one end of the electric push rod 4 is movably connected to the seat iron frame 3, and the other end of the electric push rod 4 is movably connected to the surface of the backrest iron frame 1. When the electric push rod 4 rises, the backrest iron frame 1 can rotate above the seat iron frame 3, and the eccentric motor assembly 6 can be driven to rotate together through the linkage U-shaped tube 2 and the linkage rod 5.

[0026] Furthermore, a fixed plate is provided on the surface of the speed reducer 64. The eccentric motor assembly 6 and the linkage U-shaped tube 2 are fixedly connected through the fixed plate.
