The elevator wheel 2 is assembled by four-wheel discs 21. When the elevator wheel 2 slides into the escalator, the four-wheel discs 21 can be engaged with the grooves of the escalator. Since the guide rails and pedals of different escalators may have different sizes, the tire diameter and width of the elevator wheel need to be adjusted according to the size of the specific elevator. The outer edge of the four-wheel disc 21 is an inwardly expanding cone, which can adapt to escalators of different sizes. Two adjustable brake assemblies 3 are fixedly arranged on both sides of the shopping cart bracket 1. When escalators of different sizes are engaged with the elevator wheel, the brake assembly can adjust the height at will to play a braking role.

[0023] The shopping cart support 1 includes two vertical side panels 11 and a horizontal top panel 12.
