The front end of the pedal 1 is provided with a mounting seat 6, and a mounting space 9 is formed on the mounting seat 6. The bottom end of the connecting frame 2 is arranged in the mounting space 9 and is rotatably connected to the mounting seat 6. The connecting frame 2 can rotate relative to the mounting seat 6. A connecting member 7 is provided at the bottom end of the connecting frame 2. A safety member 22 is slidably provided in the connecting member 7. One end of the safety member 22 is exposed at the rear end surface of the connecting member 7. A limiting hole 26 is provided on the mounting seat 6. The outer end of the safety member 22 is arranged in the limiting hole 26 and is engaged with the mounting seat 6, so that The connection frame 2 is restricted from rotating relative to the mounting seat 6. A clamping block 10 is rotatably provided in the mounting space 9. A first clamping groove 13 is provided on the front end surface of the connecting member 7. The top end of the clamping block 10 is arranged in the first clamping groove 13 and is clamped with the connecting member 7, thereby restricting the connection frame 2 from rotating relative to the mounting seat 6. An unlocking member 8 is rotatably provided on the mounting seat 6. The unlocking member 8 is connected to the clamping block 10. After the driving safety member 22 moves out of the limiting hole 26 and contacts the mounting seat 6 and is clamped, the unlocking member 8 is rotated to drive the top end of the clamping block 10 to disengage from the first clamping groove 13. At this time, the connection frame 2 can be rotated to a folded state relative to the mounting seat 6. An abutment plate 37 is fixedly provided at the rear end of the mounting seat 6. A threaded plate 37 is provided on the abutment plate 37.
