Electric heating alloy wire secondary expansion thermal shrinkage equipment based on spacecraft

The invention relates to the field of spacecrafts, and particularly relates to electric heating alloy wire secondary expansion thermal shrinkage equipment based on a spacecraft. The invention aims to provide the electric heating alloy wire secondary expansion thermal shrinkage equipment based on the spacecraft. According to the technical scheme, the electric heating alloy wire secondary expansion thermal shrinkage equipment based on the spacecraft comprises a bottom plate assembly, a support and the like; and the bottom plate assembly is fixedly connected with the support. According to the electric heating alloy wire secondary expansion thermal shrinkage equipment, an electric heating alloy wire is extruded, then the electric heating alloy wire is cut off, then the electric heating alloy wire is limited, then the loose wire is tightened, meanwhile, the electric heating alloy wire is subjected to position correction, so that the electric heating alloy wire is kept straight and is prevented from being bent, the
