[0025] The effect achieved by the entire embodiment 1 is that when the dining chair body 3 needs to be folded and stored, the two electric push rods 7 are started. Since the two rotating blocks 6 rotate on the two first rotating shafts 5, and the two electric push rods 7 are both installed on the two rotating blocks 6, the two straight rods 8 are driven to move. Since the two straight rods 8 are both movably mounted on the two circular shafts 13, and the two circular shafts 13 are both fixedly passed through the two moving blocks 12, the two moving blocks 12 are driven to move inside the two moving grooves 11 through the two straight rods 8. Secondly, since one end of the two folding legs 10 is movably mounted on the two first support shafts 9, the two folding legs 10 are driven to rotate on the two first support shafts 9, and then the two folding legs 10 can be folded up. Finally, through the action of the fixed shaft 2, the dining chair body 3 is rotated on the fixed shaft 2, so that the dining chair body 3 can be folded up, reducing the occupied space of the dining chair.

[0026] Embodiment 2, as Figure 2-Figure 4As shown, a rotating shaft 14 is fixedly installed at the bottom of the dining chair body 3, and a retaining bar 15 is movably sleeved on the outer wall of the rotating shaft 14, and two limiting rings 16 are fixedly sleeved on the outer wall of the rotating shaft 14. A backrest 17 is fixedly installed between one side of the outer wall of the two fixed legs 1, and two vertical grooves 18 are provided on one side of the outer wall of the backrest 17. A second support shaft 19 is fixedly installed between the inner walls of the two vertical grooves 18, and armrests 20 are movably sleeved on the outer walls of the two second support shafts 19.
