Abstract (en)
The tool has metallic cylindrical lugs (22) fixed rigidly on a plate (14), and metallic cleats (44) fixed at end of respective cylinder rods in a chassis (34). Width of the cleats is lower than that of holes (24) in the lugs. A motor assembly (12) comprising cutting units is integrated rigidly on lower part of the plate. The lugs and the cleats allow integration and disintegration of the plate to and from lower end of the chassis.
