摘要：A turning mechanism for skateboards includes a plate fixed to the underside of the board and a wheel frame is pivotably connected to the pivot tube on the plate. A first part extends through a lug on the plate and a second part is threadedly connected to the first part. A U-shaped first restriction member extends through a spring and is connected to the second part, and two hook ends of the first restriction member are hooked to a first end of the spring. A U-shaped second restriction member extends through the spring and is connected to a rod on the wheel frame. Two hook ends of the second restriction member are hooked to a second end of the spring. The second part moves linearly to pull the spring when rotating the first part so as to restrict the required force that the wheel frame is pivoted relative to the pivot tube.
