<p>A key clamping device includes a first key clamp, a second key clamp and a rotational device connected to the first and second key clamps. The rotational device may facilitate rotation of the first and second key clamps. The key clamping device may include a belt to interconnect the rotational device, first key clamp and second key clamp. The belt may engage a gear connected to the first key clamp, a gear connected to the second key clamp, and a gear connected to the rotational device to translate rotation of the rotational device to the two key clamps.</p> |
