The utility model relates to a compound load normal position nanometer indentation testing arrangement of drawing - bending belongs to accurate scientific instrument and mechanics of materials testing machine field. The testing arrangement global architecture distributes for the cross, and by tensile load -on module, crooked load -on module and indentation load -on module triplex, in the middle of tensile load -on module was arranged in, crooked load -on module and indentation load -on module distributed in the both sides of tensile module, tensile load -on module, crooked load -on module and indentation load -on module are constituteed by the accurate determine module of drive assembly, drive assembly, executive module, displacement signal and power signal, the loading line of force of tensile load -on module, crooked load -on module and indentation load -on module is in the coplanar. Can realize the synchronous sampling to load displacement signal, to servo drive system's closed -loop control. This device structure is small and exquisite, can be compatible with mainstream optical microscope, realize the many load in situ test to the macroscopical test piece of characteristic dimension more than the millimeter level.
