Nail box and anastomat

Abstract

The nail box comprises a jaw part and a main body part, the near end of the jaw part is connected with the far end of the main body part, the jaw part comprises a nail abutting seat, a nail box base and a nail bin assembly, the near end of the nail abutting seat and the near end of the nail box base are both connected with the far end of the main body part, and the nail abutting seat and the nail box base can move relatively to conduct closing and opening actions. The nail bin assembly is detachably arranged in the nail box base and comprises a cutting knife and a knife holder, and a knife handle of the cutting knife is movably connected with the knife holder; the nail bin assembly is provided with a sliding groove allowing the cutting knife to slide, and limiting intervals are arranged on the surfaces of the two side walls of the near end of the sliding groove correspondingly. When the handle of the cutting knife is located in the near-end limiting interval of the sliding groove, the cutting knife is located in the sliding groove of the nail bin assembly, and otherwise, the cutting knife is located on the upper surface of the nail bin assembly. The mode that the cutting knife and the knife holder are movably connected is adopted, the cutting knife is only located on the upper surface of the nail bin assembly in the percussion process, and the technical problem that a cutting edge is prone to being damaged due to the fact that the cutting knife is exposed outside all the time is effectively solved.
