[0023] The utility model arranges a plurality of U-shaped seats 8 at the bottom of the fixing plate 7, and arranges a telescopic support rod 9 in the U-shaped seat 8. During use, the telescopic support rod 9 supports the bottom of the chassis 2, and then the seat 1 is moved to the bottom of the chassis 2, and then the seat 1 and the chassis 2 are fixed, which is more convenient to use.

[0024] like Figure 3 As shown, the connecting member includes a connecting block 12, the bottom of the connecting block 12 is fixedly connected to the upper end surface of the seat 1, the upper end surface of the connecting block 12 is provided with a plurality of slide grooves 13, the inner wall of the slide groove 13 is slidably connected with a slider 14, and the upper end surface of the slider 14 is fixedly connected to the bottom of the fixing plate 7.

[0025] By providing the connecting block 12, the slide groove 13 and the slider 14, the design facilitates the staff to install and disassemble the seat 1 and the chassis 2 during the installation of the office chair, making it more convenient to use and reducing the installation time of the staff.

[0026] like Figure 3 As shown, a plurality of limiting grooves are formed on the side wall of the connection block 12 , and the inner walls of the limiting grooves are slidably connected to the limiting rods 16 .

[0027] By setting a limiting groove and a limiting rod 16 on the side wall of the connecting block 12, the design can limit the slider 14 in the slide groove 13 through the limiting rod 16 during use, preventing the slider 14 from sliding out of the slide groove 13 during use, thereby affecting the safety of the user.
