a supporting plate 31 disposed at the bottom of the seat cushion frame 3, and one end of the supporting plate 31 extends downward in a tilting manner to be fixedly connected with the supporting frame 1;
the guide rod 32 is arranged on the supporting plate 31 in a penetrating way;
the pressing plate 33 is arranged at the top of the supporting plate 31, and the pressing plate 33 is fixedly connected with the guide rod 32;
the spring 34 is sleeved on the guide rod 32, and two ends of the spring 34 respectively prop against the bottom of the pressing plate 33 and the top of the supporting plate 31.
For example, in order to prevent the seat cushion frame 3 from turning down, the seat cushion frame 3 is abutted against the pressing plate 33, the pressing plate 33 is abutted against the spring 34, the spring 34 is abutted against the supporting plate 31, and the guide rod 32 is used for limiting, so that the spring 34 cannot be separated from the space between the pressing plate 33 and the supporting plate 31, and the spring 34 is used for supporting, so that the seat cushion frame 3 cannot be turned down, limiting the seat cushion frame 3, preventing the downward turning, and causing the problem that a user slides down on the seat cushion.
