The invention discloses an aircraft fixture clamping plate based on a variable-proportion shear fork mechanism. The aircraft fixture clamping plate comprises a plurality of stages of shear fork unitshinged in sequence, each shear fork unit comprises a first connecting rod and a second connecting rod hinged to the first connecting rod, and the hinge point of the first connecting rod in each stageof shear fork unit is arranged in variable proportions according to the contact point of the first connecting rod and a supporting curved surface, and the hinge point of the second connecting rod in each stage of shear fork unit is arranged in variable proportions according to the contact point of the second connecting rod and the supporting curved surface; and positioning and compressing assemblies or appearance positioning assemblies for positioning and fixing the supporting curved surface are arranged on the sides, close to the supporting curved surface, of the first connecting rods or thesecond connecting rods. The aircraft fixture clamping plate has the advantages of being effectively attached to the supporting curved surface for positioning and supporting, and being simple in structure, practical, convenient and good in opening and closing performance.
