Modular clamping system

A method of mounting a structure on a substrate having a hole, the method comprising:

• inserting the structure in the hole, the structure coupled to at least one clamping system in an open position, the at least one clamping system comprised of:
• a housing;
• a link assembly comprising:
• a right first link pivotally coupled to the housing,
• a left first link pivotally coupled to the housing, and
• a second link pivotally coupled to the right first link and the left first link, and slidably coupled to the housing;
• a clamping assembly, wherein a portion of the clamping assembly is encased within the housing and configured to slidably move within the housing, the clamping assembly further comprising a clamping arm coupled to an expandable link, the expandable link coupled to the second link;
• a clamping lever pivotally coupled to the second link, the second link pivotally coupled to the housing, wherein the clamping arm is in an open arm position when the clamping lever is in an open lever position, the open arm position including the clamping arm located entirely within a perimeter of the hole when the structure is inserted in the hole and the clamping arm not in contact with the substrate, and whereby moving the clamping lever to a closed lever position moves the clamping arm to a closed arm position such that the clamping arm is located at least partially outside the perimeter of the hole and contacts the substrate;
• moving the clamping lever from the open lever position to the closed lever position, resulting in a movement of the clamping arm from the open arm position to the closed arm position.
