The present utility model disclosed a main support frame, which has two bushings each set on the right and left side of said main support frame respectively; two supporting pipes, each inserted in one of the bushings of the main support frame; two P-shaped armrests, each connects with one of the supporting pipes; two pairs of front-wheel assembly and rear wheel assembly, each pair of front-wheel assembly and rear wheel assembly is connected with the main support frame; and a seat component comprising a seat body and a folding mechanism, said seat component can be folded in the middle and is set between the left side and right side of main support frame. Said folding mechanism consists of a first branch pipe and a second branch pipe, which hinge joint with each other in the middle, one end of the first branch pipe and the second branch pipe hinge joint with the left side and right side of the main support frame respectively, the other end connect with the two ends of said seat body respectively. The improvements of the magic rollator are that: the structure is simple, it is easy to be folded and the folded volume of it is small, it stands stably and is convenient for storing and transporting, the height of it is adjustable to meet the requirements of different users; the components of it are easy to be processed, the cost is low, meanwhile the components are assembled by bushing parts and jointed together by elastic blocking joints, it is unnecessary to use special tool to mount or dismount it, so it is suitable for customers to use.
