Based　on　the　demand　for　rescue　and　demolition　technology,　the　design　of　a　new　integrated　drilling-and-coring　accessory　is　proposed.　SolidWorks　is　used　for　the　3D　design　and　modeling　of　the　accessory,　and　the　principles　of　both　the　cutting　and　coring　states　of　the　accessory　are　analyzed.　In　addition,　the　mechanical　properties　of　the　grasping　mechanism　and　turntable　are　analyzed　during　both　cutting　and　coring,　and　the　strengths　of　each　are　verified　in　terms　of　design.　Finally,　the　forces　experienced　by　the　disc　saw　during　working　conditions　are　analyzed.　The　forces　experienced　by　the　turntable　are　considered　under　inertial　force　conditions,　coupled　with　the　sawing　forces.　These　simulated　analyses　are　carried　out　using　ADAMS　(TM),　which　lays　the　foundation　for　the　subsequent　optimization　analysis.
