摘要
目的研究一种内压式边柱结构叶片锁的技术开启形成的痕迹特征。方法使用插片类工具技术开启此类锁芯,拆解锁具,观察锁具零部件上的痕迹反映,分析痕迹形成过程,总结留痕特征。结果技术开启后的锁芯叶片内壁凸起位置周围留下明显痕迹,其中凸起顶端与侧面位置与正常使用痕迹区别明显,在边柱顶端上边缘形成“点、条坑状”凹陷印痕。结论此插片类工具开启叶片锁芯留痕程度明显,可以鉴别。
Purpose Study the characteristics of the toolmarks formed by the technical opening of a blade lock with internal pressure side column structure.Methods Picking the lock,disassemble the lock,observe the mark reflection on the parts of the lock,analyze the mark formation process,and summarize the characteristics of the mark.Results After the lock is opened by technology,obvious marks are left around the raised position of the inner wall of the lock cylinder blade,and the positions of the raised top and side are obviously different from the normal use marks.A“point,pit-like”depression mark is formed on the top edge of the side pillar.Conclusion After the blade lock is technically opened,the lock core has obvious marks and can be identified.
