A second through slot 98, a third through slot 99 is formed through the top of the second support plate 92, and one side of the first through slot 97, the second through slot 98 and the third through slot 99 are all open. By installing the positioning bolt 19 at the positioning hole close to the aisle of the carriage, and by moving the seat 1 and the mounting mechanism 9, the second through slot 98 is stuck on the outside of the positioning bolt 19, so that the hole position on the high-speed rail seat and the positioning hole on the carriage floor can be aligned, the positioning bolt 19 is removed and the seat 1 is initially fixed to the carriage floor with the fastening bolts, and the seat 1 is completely fixed to the carriage floor after the mounting mechanism 9 is removed, so that the seat is straightened and installed at one time, reducing the labor intensity of the workers during the installation process.
