[0032] In one embodiment, through holes are evenly formed in the outer side of the second support plate 3, and the pin rod 15 penetrates through the through holes. After the adjustment is completed, the first connecting seat 11 and the second connecting seat 13 are limited and fixed by the pin rod 15. In addition to this design, a cylindrical rod such as a steel rod can also be used to replace the pin rod 15 to limit and fix the first connecting seat 11 and the second connecting seat 13.

[0033] In one embodiment, a limiting groove is formed in the top of the seat board 4, and the clamping plate 6 and the limiting rod 7 are embedded in the limiting groove. The clamping plate 6 and the limiting rod 7 are embedded in the limiting groove. The seat cushion 5 is installed on the top of the seat board 4 through the clamping plate 6 and the limiting rod 7, so as to prevent the seat cushion 5 from sliding. At the same time, when the seat cushion 5 is disassembled and cleaned, the limiting rod 7 at the bottom of the seat cushion 5 is separated from the seat board 4, so as to separate the seat cushion 5 from the seat board 4, which is convenient for disassembly and cleaning.

[0034] In one embodiment, a clamping groove is formed in the outer side of the inserting rod 10, and the limiting ring 8 is fastened to the clamping groove by interference fit. The connecting plate 9 is limited by the limiting ring 8, so that the inserting rod 10 is buckled inside the limiting rod 7. A connecting plate 9 is arranged at the bottom of the inserting rod 10, and the connecting plate 9 is located at the bottom of the seat board 4, so as to limit the seat cushion 5 and facilitate the disassembly and assembly of the seat cushion 5.

[0035] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
