The seat plate 2 is installed and connected with the fixed seat 3 by rotating the rotating shaft 8 and inserting the rotating shaft hole 4, and the sliding circular groove 9 is rotated and inserted into the recessed truncated cone 5. Rotating shaft seats 10 are formed at both ends of the front part of the seat plate 2. Pedals 11 are rotatably connected to the two rotating shaft seats 10. A raised column 12 is formed in the middle of the front end of the bottom of the seat plate 2 and is relatively matched with the engaging cavity 6. A cylindrical cavity 13 is formed in the raised column 12 and is relatively matched with the cylindrical groove 7. A corresponding A coaxial return spring 14 is provided, and a support column 15 is embedded in the cylindrical cavity 13 and is engaged with the cylindrical groove 7. The raised column 12 forms a translation sliding cavity 16 that penetrates to the outside on both side walls of the cylindrical cavity 13, and limit columns 17 are formed on both side walls of the support column 15 and are opposite to the translation sliding cavity 16 on the same side; two limit plates 18 are formed on the inner end of the bottom wall of the pedal 11 and are respectively attached to the two side walls of the raised column 12. An arcuate sliding cavity 19 is formed on the limit plate 18 and is opposite to the translation sliding cavity 16. The outer end side of the limit column 17 extends from the arcuate sliding cavity 19 into the arcuate sliding cavity 19.

[0024] Among them, when the raised column 12 of the pedal 11 is relative to the embedded cavity 6 and the pedal 11 is set obliquely downward, the limiting column 17 is at the lower end of the arc-shaped sliding cavity 19 on the limiting plate 18, the return spring 14 is in a natural state, and the support column 15 is embedded in the cylindrical groove 7; when the raised column 12 of the pedal 11 is relative to the embedded cavity 6 and the pedal 11 is set obliquely upward, the limiting column 17 is at the upper end of the arc-shaped sliding cavity 19 on the limiting plate 18, the return spring 14 is in a compressed state, the support column 15 translates in the direction away from the cylindrical groove 7, and the support column 15 moves out of the cylindrical groove 7; a recessed cavity 20 is formed between the rotating shaft hole 4 and the recessed cone 5 at the top of the fixed seat 3; the bottom end of the rotating shaft 8 is limited to the bottom of the fixed seat 3 by using a bolt member, so that the bottom end of the rotating shaft 8 cannot fall out of the fixed seat 3, which is convenient for the rotating shaft 8 to rotate steadily in the rotating shaft hole 4.
