发明名称 Spring actuated spread clamp
摘要 A spring actuated clamping device is disclosed for woodworking applications and the like. The device is applicable to those situations where it is desired to exert clamping forces in opposite directions against two surfaces facing one another. The device comprises two arms which are pivotally attached to each other. The distal ends of the arms are urged to pivot outwardly by a spring. Pivotable pads at the distal end of each arm provide a flat contacting surface regardless to the extent the arms are pivoted.
