摘要： A multi-ring type leg-wheel comprises a leg-wheel outer ring, a inner ring, and a center cap. The leg-wheel outer ring has a wheel configuration with a shaft support ring located in the middle portion of the leg-wheel outer ring, and there are a plurality of tapered-section hooks equally spaced around the circumference of the shaft support ring. On the outer side of the leg-wheel outer ring, there is cylindrical concaved space. The inner ring has a ring-like configuration; and from the immediate circumference of inner circle of inner ring, there extend a plurality of circumferentially equally spaced cantilever type claws along the axial direction. At the end of each claw, there is a tapered section hook along the claw's width. The center cap has a short barrel shape and it's diameter is equal to the diameter of center hollow space of the inner ring.
