Battery clamp device

A battery clamp device, comprising:

• a first inner metal battery clamp member having a handle portion, a clamp portion, and a first pair of pivot plate portions;
• a second inner metal battery clamp member having a handle portion, a clamp portion, and a second pair of pivot plate portions overlapping with the first pair of pivot plate portions, the second pair of pivot plate portions having arc-shaped flanges protruding outwardly from the sides of the second inner metal battery clamp member to accommodate the first pair of pivot plate portions, wherein the first pair of pivot plate portions are arc-shaped and nest within the arc-shaped flanges of the second inner metal battery clamp member;
• a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp member, the handle portion of the first outer insulating battery clamp member including a first flat inner edge extending along a first axis;
• a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp member, the handle portion of the second outer insulating battery clamp member including a second flat inner edge extending along a second axis, the second flat inner edge being substantially flush with the first flat inner edge when the battery clamp device is fully opened;
• and
• a pivot pin positioned at an intersection of the first axis and the second axis, the pivot pin pivotally connecting the first inner metal battery clamp member to the second inner metal battery clamp member, the first outer insulating battery clamp member or the second outer insulating battery clamp member including a protective cover section covering an end of the pivot pin.
