Claims

[Claims for Utility Model Registration] A mechanical plug removal device containing a core with a tapered surface, comprising a connecting means including a mandrel that is screwed into the plug, a core pushing means, and a main body that moves the pushing up means and the coupling means up and down. It is characterized by comprising a lifting means, a means for grasping the pulled out plug, a means for recovering the plug, a sequence control means for controlling the operation of each of these means, and a support frame body incorporating the above-mentioned means as one unit. Automatic mechanical plug removal tool.
