The second connection part 20 is formed with a receiving cavity 21, which is convenient for the assembly of the second connection part 20 and the pedal bracket 30, and improves the bending and torsion resistance of the second connection part 20. At the same time, the weight of the connection bracket 100 can be reduced, and the material distribution of the connection bracket 100 can be more reasonable.
