Furthermore, the front and rear parts of the wheel axle 21 can be supported by the two bosses 1211, so that when the wheel axle 21 is subjected to force, the load distribution on the wheel axle 21 is more uniform, thereby avoiding local damage to the wheel axle 21 due to excessive force at a single point, significantly reducing the deformation of the wheel axle 21, and extending the service life of the wheel axle 21.

[0051] It should be noted that the upper frame 11 is provided with two mounting through holes 110 , and each mounting through hole 110 can accommodate a pedal assembly 5 .
