• intros：{"brand_intro":"得力（Deli）成立于1981年，中国办公用品巨头，2015年进军手动工具领域。创始人娄甫君以\"让工具更简单\"为理念，依托集团供应链优势快速崛起。得力工具拥有200多项专利，其瓷砖切割刀采用\"一体成型\"工艺，成本控制能力行业领先。品控通过ISO 9001认证，每批次产品进行100%功能测试。得力以\"高性价比+全渠道覆盖\"策略，在电商平台销量长期居前。","product_intro":"DL-40是得力入门级爆款，主打极致低价和基础功能。核心卖点：40mm切割深度、轻量化设计（0.9kg）、防滑手柄。相比东成，得力价格再低40%，但刀轮材质为普通碳钢，寿命较短。适用场景：普通釉面砖、小规格瓷砖，适合临时修补或少量切割。竞品对比中，其优势在于价格最低、购买方便（全国3万家门店），劣势是切割精度和耐用性一般。","key_specs":{"切割深度":"40mm（固定深度）","刀轮材质":"碳钢（洛氏硬度HRC55）","导轨长度":"450mm（单轴承）","最大切割长度":"300mm","重量":"0.9kg","适配人群":"临时修补用户、预算极低的家庭用户"}}
