Hand-held battery powered center punch band clamp tool

A band clamp tensioning apparatus to tension and lock a center punch band clamp having a band and a buckle, said apparatus comprising:

• a hand-held power tool having a main body and an electrical power source, said tool configured for rotationally driving a chuck disposed the distal end thereof;
• a band tensioning assembly attached to said power tool;
• said band tensioning assembly including a gear box, a gear box mount coupled to said gear box, and said gear box mount mechanically coupled to said chuck;
• said gear box including a worm gear axially coupled to the chuck for powered driven rotation thereby;
• a winder gear in intermeshing relation with said worm gear for rotation about an axis disposed generally perpendicular to the worm gear axis;
• said winder, defining at least one band-receiving slot;
• a punch assembly, defining a slot, connected to the distal end of said gear box with the slot disposed in forwardly spaced aligned relation with said winder;
• said punch assembly including a pivotal punch movable between a stowed configuration and a deployed configuration, said pivotal punch having a first end pivotally connected to said gear box, and a second end having a first side adapted with a generally pointed tip and an opposing, generally planar second side that provides a surface for receiving an impact blow from a blunt striking implement, said pivotal punch disposed such that said pointed tip engages the buckle of the band clamp thereby deforming the buckle so as to securely lock the band clamp.
