[0025] A plug-in block 8 is installed in the middle of one end of the backrest 5 near the mounting part 7. A plug-in groove 9 is opened on the top of the mounting part 7 near the plug-in block 8. A fixing rod 14 is slidably installed on the side wall of the plug-in block 8 near the plug-in groove 9. A bottom abutting arc surface 16 is provided at one end of the fixing rod 14. A fixing spring 15 is connected to the other end of the fixing rod 14. Two fixing rods 14 are symmetrically arranged to facilitate the limiting and fixing of both sides of the plug-in block 8, which can improve the stability of the backrest 5 installation. The cross-section of the plug-in block 8 and the plug-in groove 9 are both T-shaped. One end of the plug-in block 8 is fixedly installed on the backrest 5, and the other end of the plug-in block 8 is slidably connected to the inner wall of the plug-in groove 9, which facilitates the lateral limiting of the plug-in block 8 through the plug-in groove 9. The fixing rod 14 is T-shaped. A telescopic groove 18 is formed on the side wall of the plug block 8 near the fixing rod 14. Two fixing springs 15 are arranged parallel to each other inside the telescopic groove 18. One end of each fixing spring 15 is fixedly connected to the fixing rod 14, and the other end of each fixing spring 15 is fixedly installed on the inner side wall of the telescopic groove 18. The end of the fixing rod 14 away from the abutting arc surface 16 is slidably connected to the inner wall of the telescopic groove 18, and the other end of the fixing rod 14 slides out of the telescopic groove 18.
