[0027] The disassembly and assembly mechanism 11 includes a T-shaped insert 12, a plurality of limit inserts 13, a limit insert column 14, a limit block 15, a limit insert plate 16, two limit sliders 17, two round rods 18 and two telescopic springs 19.

[0028] The second mounting block 9 is provided with two slots, and the second connecting block 10 is provided with two jacks, which correspond to the two slots one by one. One end of the T-shaped insert 12 passes through the jack and extends into the slot, and the T-shaped insert 12 is adapted to the jack and the slot.

[0029] The inner wall of the slot is provided with a plurality of limit grooves, the T-shaped insert 12 is provided with a plurality of through openings, and a plurality of limit plugs 13 are hingedly mounted on the plurality of through openings, respectively.
