[0028] The foot pedal 2 is made of metal material, and there are two sets of pedals that can be disassembled and assembled, and are symmetrical to each other along the vertical center axis of the bracket 1. The foot pedal 2 is located on the side of the bracket 1. The metal material is relatively hard and can withstand a heavier weight.

[0029] A deceleration device 4 is provided at the bottom of the foot pedal 2, and the deceleration device 4 includes a connecting plate 41.

When disassembling, the sliding rod 36 is slid through the elastic force of the spring 1 33 so that the limit rod 37 no longer restricts the fixed block 34, and the extrusion rod 32 can be reset, and the two push rods 39 can be retracted to remove the foot pedal 2. The foot pedal 2 is suddenly removed and falls down too fast, which may affect the safety. The wheel 42 is slidably connected to the bracket 1, and the resistance block 45 is close to the bracket 1.
