Crushing pedal mechanism

The invention discloses a crushing pedal mechanism. A main bracket and rotating bracket of the crushing pedal mechanism are provided with limiting grooves respectively, and the relative fixation of the main bracket and rotating bracket is achieved through a limiting bracket of which one end penetrates through the limiting grooves; the main bracket, the other end of the limiting bracket and a connecting bracket are in locked connection through fasteners, and the length of a guide groove of the main bracket is larger than the limiting length of the limiting bracket, so that when the main bracketis impacted, a limiting part, moving relative to the connecting bracket, of the limiting bracket slips off from the limiting groove, thereby achieving crushing of the crushing pedal mechanism. The crushing pedal mechanism has the advantages that the structure is ingenious, not only can crushing be ensured when a pedal is impacted to protect a driver from damage, but also accidents caused by pedalcrushing under normal dri
