The operation is simple and convenient, which is conducive to improving the user experience.

[0039] Reference Figure 3 , Figure 5 , Figure 7 and Figure 8 According to the pedal assembly provided by the embodiment of the first aspect of the utility model, the locking piece 120 is provided with a second locking portion 123, and the second locking portion 123 is located on the side of the locking piece 120 facing the locking sleeve 110. The outer wall of the locking sleeve 110 is provided with a fixing groove 116 connected to the first locking groove 111. When the pedal 150 is in a folded state, the first locking portion 121 is snapped into the first locking groove 111, and the second locking portion 123 is snapped into the fixing groove 116. The first locking portion 121 cooperates with the second locking portion 123 to better make the pedal 150 hover, and can prevent the pedal 150 from rotating downward due to unstable fixation when in the folded state.

[0040] Reference Figure 2 , Figure 4 and Figure 6According to the pedal assembly provided by the embodiment of the first aspect of the utility model, the outer wall of the locking sleeve 110 is further provided with a receiving groove 117. When the first locking portion 121 is inserted into the second locking groove 113, the second locking portion 123 is located in the receiving groove 117, which is conducive to improving the compactness of the structure.
