The invention discloses a labor-saving optimization method for a shear fork lifting mechanism. The labor-saving optimization method comprises the steps that (1) the structure of a shear fork lifting assembly is optimized; (2) carrying out labor-saving optimization verification on the optimized scissor lifting assembly structure; (21) carrying out stress analysis on the structure before optimization to obtain a lead screw thrust FEX expression; (22) carrying out stress analysis on the optimized structure to obtain an optimized lead screw thrust FEX 'expression; (23) comparing the FEX obtained in the step (22) with the F' EX obtained in the step (23); under the condition that the size condition and the load condition of the shear fork assembly are the same, F 'EX is obviously smaller than FEX. After an existing structure is subjected to stress analysis, conventional thinking is jumped out under the same condition, the layout of the overall structure is subjected to fine adjustment, the overall service life is prolonged, and the working efficiency of the shear fork assembly is improved.
