The present invention working method be；When straight line moving, as long as both hands are held the side of handlebar two and uniformly exerted oneself, at this moment Four wheels that soil fertility is identical, and front and rear two axletree is that four wheels do not do go to action parallel and perpendicular to vehicle body, Namely perambulator is in straight line moving posture, when to turn for example to turn right when, as long as the right hand firmly tilt down, At this moment front right wheel soil fertility and is more than preceding left wheel, along with preceding channel-section steel body and front truck standpipe tilt 10 degree of reasons, And make it that this power forces front axle to rotate clockwise, simultaneously because the rotation of front axle and rear channel-section steel Body, rear car standpipe, which tilt 10 degree of reasons, can also cause the rotation of rear car axially opposite direction, so front left car Wheel, front right wheel turn right, and rear left wheel, rear right wheel turn left so as to drive perambulator to turn right very well, Similarly as long as left hand exerts oneself to tilt down the purpose that also can reach left-hand bend.

The beneficial effects of the invention are as follows：Because four rotate when turning simultaneously, so turning diameter I original place is fallen Head and the place use in narrow field, another benefit is the perambulator obstacle detouring made greatly very much that front vehicle wheel can design Ability and shake-proof ability are good.
