The invention provides a two-degree-of-freedom micro-displacement assembly, and belongs to the field of a micro-displacement platform structure. According to the two-degree-of-freedom micro-displacement assembly, a second part is fixed on a base, a first part is fixed on a flexible mechanism, the relative displacement between the first part and the second part is adjusted through a moving portion of the fine-tuning flexible mechanism, the flexible mechanism can employ an integrated machining mode so that the flexible mechanism avoids an assembling gap between a kinematic pair in a conventional rigid mechanism, the whole mechanism avoids friction and lubrication, the energy loss and the mechanical hysteresis caused by the friction and the gap are avoided, the precision of the mechanism is greatly improved, the service lifetime of the mechanism is greatly prolonged, the assembling of the flexible mechanism is simple, and the guiding precision can be greatly improved.
