Of course, in other embodiments, the limiting ribs 126 may connect only two opposite sidewalls of the slot 122 and be spaced apart from the bottom of the slot 122.

In one embodiment, each slot 122 has a limiting rib 126 therein. The plurality of limiting ribs 126 are distributed along the arrangement direction of the plurality of slots 122, and the plurality of limiting ribs 126 are arranged linearly. Equal to all having spacing recess 312 on each pole piece 31, spacing protruding muscle 126 can support and hold on each pole piece 31, has improved the area of contact of seat body and pole piece 31, can guarantee the stability of seat body, and when the seat body received external effort moreover, spacing protruding muscle 126 can support simultaneously and hold a plurality of pole pieces 31 for the atress of a plurality of pole pieces 31 is even, and overall stability is better.

In one embodiment, the limiting ribs 126 extend along the arrangement direction of the slots 122 and connect two opposite sidewalls of the slots 122. The groove bottom of slot 122 and two adjacent picture peg 121 are connected simultaneously to spacing protruding muscle 126 promptly, have increased the area of contact of spacing protruding muscle 126 with picture peg 121, have improved the structural strength of spacing protruding muscle 126, have greatly improved the resistance to deformation ability of spacing protruding muscle 126, and spacing protruding muscle 126 can also play the effect of strengthening rib in addition, can increase the intensity of picture peg 121. Of course, in other embodiments, the spacing ribs 126 may be spaced from the side walls of the slot 122.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
