During the rotation, the rotating component 8 drives the gearbox lever 5 to rotate in the fourth direction, so that the gearbox 1 is in reverse gear. The first direction is opposite to the third direction, and the second direction is opposite to the fourth direction.

[0031] It should be noted that since the two ends of the rotating part 8 are fixedly connected to the forward lever 6 and the backward lever 7 respectively, when the forward pedal 31 or the backward pedal 41 is pressed, it will drive the other pedal to rotate.

[0032] In an optional embodiment, see Figure 4 When the forward pedal 31 is depressed, the second end of the rotating part 8 rotates toward the side of the transmission 1, and the transmission lever 5 moves toward... Figure 5 The movement is in direction 'a' as shown; see also Figure 5 When the reverse pedal 41 is pressed, the second end of the rotating member 8 rotates toward one side of the second fixed shaft 10, and the gearbox lever 5 moves in the opposite direction to direction a.
