摘要

Hydraulic processing plier has piston (18) and/or piston rod (17) fitted with cavity in which tool plunger or plunger (12) is absorbed with partial length in plunger initial position. Pressure transfer element (21), in its pressure transfer working position, forms cavity of piston and/or piston rod. Pressure transfer element locks contact surface of tool plunger or plunger at piston or piston rod of actuation equipment (5).
