Steering mechanism of handle-controlled skate board

A steering mechanism of handle-controlled skate board comprising a skate board, a casing fixed at front end of the skate board and a front and a rear wheel assembly respectively mounted at front and rear ends of the skate board, the front wheel assembly including two wheels and being controlled by the steering mechanism, said steering mechanism being characterized in that:

• the steering mechanism is fixed on front edge of the casing, the steering mechanism including a fixing seat, a swinging seat and a base bar;
• the fixing seat is disposed on a bottom edge of the casing, a lower side of the fixing seat having a projection for pivotally connecting with the top of a swinging seat, a driving arm being fixed on a rear side of the projection, a free end of the driving arm being formed with a spherical section;
• the swinging seat is formed with shaft holes spaced from the bottom of the swinging seat by a certain height, a pivot shaft being passed through the shaft holes so as to pivotally connect the swinging seat with the projection of the fixing seat, two wing sections laterally extending from a lower edge of the swinging seat, two compression springs being compressed between the wing sections and two sides of the projection;
• a pivot section rearward projects from the lower edge of the swinging seat for pivotally connecting with a front end of a rocking arm, an upper edge of the rocking arm being disposed with a restricting seat for receiving the spherical section of the driving arm;
• and
• a center of the bottom edge of the swinging seat is pivotally connected with the middle portion of the base bar, the base bar transversely extending to outer side of the swinging seat for mounting the wheels thereon, two sides of a rear edge of the base bar being pivotally connected with two links, opposing ends of the links being pivotally connected with a rear end of the rocking arm.
