• intros：{"brand_intro":"东成（Dongcheng）成立于1995年，中国电动工具行业龙头企业，总部位于江苏启东。创始人顾志平从五金作坊起家，坚持\"高性价比\"路线，打破外资品牌垄断。东成拥有国家级实验室和200余项专利，其手动工具产品线覆盖瓷砖切割、电钻、角磨机等，年销量超5000万件。品控采用\"零缺陷\"管理，每批次产品抽检率高达30%。东成以\"让中国工具走向世界\"为使命，产品出口80多个国家，是家装市场占有率最高的国产品牌。","product_intro":"DC-40是东成面向大众市场的入门级瓷砖切割刀，主打极致性价比。核心卖点：40mm切割深度、可拆卸刀轮、人体工学手柄。相比博世，东成在价格上低60%，但切割精度稍逊（误差约1mm）。适用场景：普通釉面砖、小规格墙砖切割，适合家庭装修和短期工程。竞品对比中，其优势在于刀轮更换方便（通用型刀轮，10元/个），劣势是导轨长期使用后易松动。","key_specs":{"切割深度":"40mm（适配10mm以下瓷砖）","刀轮材质":"高速钢（HSS，洛氏硬度HRC65）","导轨长度":"500mm（单轴承滑动）","最大切割长度":"350mm","重量":"1.0kg","适配人群":"家庭DIY用户、预算有限的装修新手"}}
