摘要： An improved skate stage comprises a wheel bracket, a spring, a mounting plate and a U-shape member. The wheel bracket have two embedding grooves on the top side thereof, the embedding groove having a positioning shaft and a positioning plate within it. The U-shape member is arranged beside the embedding groove on the top side of the wheel bracket. The U-shape member has a round groove and a blocking groove on the top side thereof. The positioning shaft having, on the lateral side thereof, a lateral hole allowing the insertion of a positioning rod which pass through a slot of a rectangular shaft, and one end of the positioning rod being fixed by a bolt. The mounting plate is embedded within the embedding groove. The rectangular shaft below the mounting plate is fitted between the positioning shaft. The fixing plate beside the rectangular shaft clamps the positioning plate of the embedding groove. A groove is provided on the bottom side of the mounting plate and beside the rectangular shaft, and the groove accommodating the spring. Another end of the spring is placed within the round groove of the U-shape member to provide elasticity between the wheel bracket and the mounting plate. The shocking force of the wheel bracket can be minimized by the elastic force of the spring and the shifting of the U-shape member within the rectangular groove.
