Abstract
This invention relates to an effort-saving binder clip, comprising clamping parts, a rear part, and rod members. When the binder clip is used, the first rod member passes through the first hole, and contacts one end of the first clamping part against the opening side of Part A, forming a first fulcrum. From the first fulcrum to the pivotal part, a gap exists between the first rod member and the first clamping part; the second rod member passes through the second hole, and contacts one end of the second clamping part against the opening side of Part C, forming a second fulcrum. From the second fulcrum to the pivotal part, a gap exists between the second rod member and the second clamping part; additional protruding fulcrums are not necessarily arranged on the clamping parts or rod members so as to save effort and greatly simplify production.
