[0021] Reference Figure 4 , dismounting structure 5 includes four dismounting clamping blocks 501, and the side of dismounting clamping block 501 close to fixed square shell 2 penetrates structure slot 4 and extends to the outside of the inner cavity of structure slot 4, two positioning holes 502 are formed in the surface of dismounting clamping block 501, spring 503 is fixedly connected to the surface of dismounting clamping block 501, and the surface of spring 503 is fixedly connected with the inner cavity of structure slot 4.

[0022] The above scheme is used: by setting dismounting structure 5, when rotatable seat 3 needs to be conveniently disassembled from seat base 1, dismounting structure 5 makes the disassembly of rotatable seat 3 more convenient.

[0023] Reference Figure 3 , the inner cavity of structure slot 4 is fixedly connected with two positioning long rods 6 used in cooperation with positioning hole 502, and the surface of positioning long rod 6 is movably connected with the inner cavity of positioning hole 502.

[0024] The above scheme is used: by setting positioning long rod 6, when dismounting clamping block 501 moves, positioning hole 502 will be moved along the surface of positioning long rod 6, and the cooperation of positioning hole 502 and positioning long rod 6 limits the moving position of dismounting clamping block 501.

[0025] Reference Figure 3 , the inner cavity of structure slot 4 movably connects four right-angle control frames 7, the top of dismounting clamping block 501 is fixedly connected with two circular extrusion columns 8 used in cooperation with right-angle control frame 7, and the inner cavity of right-angle control frame 7 is movably connected with the surface of circular extrusion column 8.

[0026] The above scheme is used: by setting right-angle control frame 7 and circular extrusion column 8, when right-angle control frame 7 moves, extrusion force can be generated to circular extrusion column 8, and circular extrusion column 8 subjected to extrusion force can drive dismounting clamping block 501 to move.

[0027] Reference Figure 3 , control hole 9 is formed in the surface of right-angle control frame 7, the inner cavity of structure slot 4 is fixedly connected with four control rods 10 used in cooperation with control hole 9, and the surface of control rod 10 is movably connected with the inner cavity of control hole 9.

[0033] In summary, this easily detachable swivel seat, through the coordinated use of the disassembly and assembly structure 5, disassembly and assembly latch 501, positioning hole 502, spring 503, and disassembly and assembly slot 11, solves the problem that existing chair swivel seats require placing the swivel seat in the correct position on the seat base and using tools such as a level to adjust it to ensure its horizontality and verticality. Then, screws, nuts, and other fasteners are used to fix the swivel seat to the corresponding position on the seat base. During disassembly, matching tools are needed to remove the screws or nuts. If the tools are not used properly during disassembly, other parts of the seat base may be damaged. Frequent removal of bolts can cause damage, and replacing bolts and other parts increases the disassembly cost. However, existing chair swivel seats do not have a component that allows for easy removal from the seat base.
