The cylinder 60 is set on the bracket 10 and connected to the three-level pedal 40 to drive the three-level pedal 40 to flip. The transmission rod 70 connects the secondary pedal 30 and the third-level pedal 40 so that the third-level pedal 40 drives the secondary pedal 30 to flip when flipping.

[0039] Specifically, the two ends of the connecting member are hinged on the third-level pedal 40 and the second-level pedal 30, and are mainly used for transmission to ensure that the linkage between the second-level pedal 30 and the third-level pedal 40 is stable and reliable. In addition, the connecting member can also play a supporting and limiting role. When there is no limiting structure between the second-level pedal 30 and the bracket 10, when the second-level pedal 30 and the third-level pedal 40 are rotated to the appropriate position, the third-level pedal 40 is fixed. At this time, the connecting member can serve as a limiting structure for the second-level pedal 30, and also play a supporting role for the second-level pedal 30.

[0040] In a preferred embodiment, a mounting groove 11 is provided on the bracket 10, and the cylinder 60 is fixedly provided in the mounting groove 11. Specifically, the cylinder 60 can be provided in the mounting groove 11 by welding, or can be fixed in the mounting groove 11 by bolts in various countries; in addition, a baffle is also provided on the mounting groove 11 to block the cylinder 60 in the mounting groove 11 to prevent the cylinder 60 from falling off.

[0043] In a preferred embodiment, the secondary pedal 30 includes a second connection seat 31 and a second stepping plate 32. The second connection seat 31 is hinged to the bracket 10 through a quick plug 50, and the second stepping plate 32 is arranged on the second connection seat 31. In detail, the second connection seat 31 is also made of steel, which has high strength and is not easy to be damaged. The second stepping plate 32 is also stamped to form a plurality of anti-slip holes.

[0044] Connecting thin plates are provided on both sides of the second connecting seat 31 . The connecting thin plates are mainly used to connect the bracket 10 and also facilitate the insertion of the quick latch 50 . The bracket 10 is also provided with a connecting thin plate for connecting with the quick latch 50 .

[0045] In a preferred embodiment, the three-stage pedal 40 includes a third connecting seat 41, a connecting plate 42 and a gas spring 43.
