Claw clamp

A clamp comprising:

• a first half comprising a first claw that protrudes from a first end of the first half, a first hole located proximal a second end of the first half, the first hole located substantially opposite the first end of the first half, and a second hole located between the first hole and the first claw, each of the first hole and the second hole having a larger diameter portion and a smaller diameter portion and a transition formed there between;
• a second half comprising a second claw that protrudes from a first end of the second half, a third hole located proximal a second end of the second half, the third hole located substantially opposite the first end of the second half, and a fourth hole located between the third hole and the second claw, the third hole in substantial alignment with the first hole and the fourth hole in substantial alignment with the second hole when the first half is aligned with the second half, the third hole and fourth hole comprising internal threads;
• a first threaded rod comprising threads on one end and a hex head or knob on the opposite end and a non-threaded portion there between, a shoulder formed in the non-threaded portion, the first threaded rod passing through the second hole and engaging the internal threads of fourth hole, the shoulder engaging the transition between the smaller diameter portion and the larger diameter portion of the second hole;
• a second threaded rod comprising a threaded portion, an enlarged end and an non-threaded portion there between, the second threaded rod passing through the first hole and engaging the internal threads of the third hole;
• and
• a spring retained by the second threaded rod internal to the first half in the larger diameter portion of the first hole between the enlarged end of the second threaded rod and the transition formed between the smaller diameter portion and the larger diameter portion of the first hole.
