The invention discloses a folding trolley which comprises a front wheel support, a seat part, a front wheel assembly capable of achieving a steering function, a rear wheel assembly capable of achieving an automatic braking function and a control part capable of controlling the front wheel assembly to steer. The front wheel assembly comprises two front wheels, a worm wheel used for driving the front wheels to rotate, a worm used for driving the worm wheel to rotate, a driven piston cylinder fixedly connected into the front wheel support, and a driven piston body connected into the driven piston cylinder in a sealed and sliding mode and used for driving the worm to rotate. The control part comprises an extension pipe connected to the front wheel support, a driving piston cylinder fixedly connected into the extension pipe, a driving piston body connected into the driving piston cylinder in a sealed and sliding mode, and a rotating grip used for driving the driving piston body to move. A closed space formed by the driving piston body and the driving piston cylinder is communicated with a closed space formed by the driven piston body and the driven piston cylinder; steering operation can be conducted with one hand, and deviation cannot occur on the inclined face inclining left and right.
