Abstract:
1. A hand-held spring clamp which provides an aid in an assembly of a work object comprising: a right side member with a removably attachable pad attachment means at a right jaw portion at a right upper end, further comprising: a left side member with a removably attachable pad attachment means at a left jaw portion located at left upper end, further comprising: a removable and interchangeable jaw pad attachable thereto said right and left jaw portions therewith said pad attachment means; a center fulcrum providing a pivoting means thereto a central location thereof each said left side member and said right side member; and, a pressure adjustment means affixed thereto said center fulcrum, further comprising: wherein said clamp provides a compliant high-friction grip that ensures that said work object of varying size and shape is held with minimal or no movement; wherein said first and second left flange comprise a width enabling said first and second left flange to bracket said first and second right flange; wherein said first and second left flanged portion and said first and second right flanged portion each comprise apertures thereby allowing said center fulcrum to pass therethrough and provide a connection means thereof said second mounting plate thereof said left side member to said first mounting plate thereof right side member; wherein said center fulcrum terminates at a first end thereto a pressure adjustment knob and at a second end thereto said second mounting plate; wherein said center fulcrum provides relative motion thereof said right side member and left side member; wherein an applied pressure thereto said right and left side members provides a separating means thereto said left jaw portion and said right jaw portion; wherein said pressure adjustment knob is manually adjusted between a maximum force and a minimum in a clockwise or counter-clockwise direction to provide minute variations of an applied pressure exerted by said jaw pads thereupon said work object; wherein when said pressure adjustment knob is manually adjusted, said torsion spring is compressed or released, thereby producing a variable torsion applied thereto said right side member via said first mounting plate; wherein said locking lever provides a securing means thereto a desired torsion thereof said variable torsion thereto said clamp; wherein when said locking lever is rotated clockwise about said center fulcrum, said incline plane forces said locking lever against a bottom surface of said pressure adjustment knob, thereby providing said securing means thereto; and, wherein said applied pressure is exerted by said jaw pads when said right handle and left handle portions are released; and, wherein said pressure adjustment means provides a selectable and variable clamping means thereto a work object.
