国外竞品部件逆向建模研究。使用三维模型软件（SolidWorks）对国外竞品脱位冰刀刀管、刀桥、缓冲座、拉簧等零部件按照实物1：1进行建模，模型材质、尺寸、物理特性与样品保证一致。主要记录了国外竞品脱位冰刀刀管、刀桥、缓冲座、拉簧的模型数据。

Research on reverse modeling of foreign competitive parts. The 3D model software (SolidWorks) is used to model the parts and components of the dislocated ice skate knife tube, knife bridge, buffer seat, tension spring and other parts of the foreign competitive products according to the physical object 1:1, and the model material, size and physical characteristics are consistent with the sample. It mainly records the model data of the dislocated ice skate tube, knife bridge, buffer seat and tension spring of foreign competitors.
