A position-returning mechanism for a pick-and-place apparatus is disclosed, in which three first circular recesses are respectively concavely provided and three fixing blocks are respectively convexly provided in an equal angle along an outer periphery on a lower surface of a fixing base, and each of the three first circular recesses is inserted and disposed between two adjacent fixing blocks. A movable base is correspondingly installed on the lower part of the fixing base. Three corresponding second circular recesses are concavely provided and three recesses are provided on an upper surface of the movable base. Three ring sprig pillars are provided and received respectively in the corresponding first circular recesses and the corresponding second circular recesses. Therefore, according to the invention, the movable base is allowed to provide functions of radial displacement and axial rotation relative to the fixing base via the three ring sprig pillars.
