A novel automatic mechanical gripper has been designed for the replacement and transport of solid waste. The structure of the gripper is mainly discussed in this paper which including the tooth slider and linkage. The gripper performs the grabbing and releasing of the solid waste automatically without any external motive force driving, and it is also meanwhile self -locked, high reliable. Its pliers can be easily changed into other forms and it has a extensive applicability, especially for the radioactive, ooisonous or anoxie environment.为完成核电工程中固体废料更换和转运，设计了一种新型的机械式自动抓具。主要阐述了抓具采用齿形滑块机构和连杆机构设计，在无外动力的条件下可自动抓取和释放固体废物，实现了抓力自锁，可靠性高、抓爪形式可变、适用性广等特点，特别对放射性、有毒、缺氧等恶劣工作环境具有很好的应用价值。
