In expression formula, L ₁In be the distances of pivot holes 427, connecting rod 42 back to fixed head 113 upper pivot holes 1131, also be the arm of force; L ₂ Being connecting rod 42 length, also is the arm of force; L ₃For the pivoting part 315 of depression bar 31 distance, also be the arm of force to the lower pivot hole 1133 of fixed head 113; L ₄For the distance of staple casket 21 front bottom end, also be the arm of force to self pivot hole 213; F ₀Be the downward application of force of user at laborsaving bar 41 front ends; F ₄For desiring the active force of bound document to staple in the staple casket 21, the push-pads 305 that also is labor-saved stapler is by staple exerting oneself to the desire bound document; F ₂, F ₃Active force for labor-saved stapler inside; θ ₀, θ ₁, θ ₃, θ ₄Being the angle of each arm of force and the application of force, below is expression formula

F ₀×sin(θ ₀)×L ₀＝F ₁×L ₁；F ₁＝F ₂×cos(θ ₁)；

F ₀×sin(86.243°)×L ₀＝F ₂×cos(47.864°)×L ₁；

151.67?F ₀＝16.77?F ₂；F ₂＝9.044?F ₀；

L ₃＝75；L ₄＝145；θ ₃＝28.964°；θ ₄＝84.441°；

F ₄×sin(θ ₄)×L ₄＝F ₃×L ₃；F ₃＝F ₂×sin(θ ₃)；

F ₄×sin(84.441°)×L ₄＝F ₂×sin(28.964°)×L；

144.32?F ₄＝35.848?F ₂；F ₂＝4.026?F ₄；

4.026?F ₄＝9.044?F ₀；F ₄＝2.246?F ₀；

Province's power rate=(2.246-1)/(2.246)=55.47%

Learn by last several expression formulas, labor-saved stapler is economized and is saved strength over half in use, so for strength little women or child, can easily use and do not need excessively to take efforts, to the injury of muscle, avoid when therefore also having reduced the use stapler because the long-term symptoms such as DOMS of using stapler to produce.
