A flexible connection plate is used in a feed drive mechanism. The flexible connection plate has a first portion, a second portion joined to the first portion, and a plurality of elastic grooves between the first portion and the second portion. The first portion and the second portion are fixed to a nut seat and a lead screw nut of the feed drive mechanism respectively. The elastic grooves are axially penetrating the connection plate. Adjacent elastic grooves have an overlapping section respectively, such that the flexible connection plate has a characteristic of elastic deformation in a radial direction, so as to absorb errors resulted from assembly, and improve non-parallelism resulted from the assembly errors, thereby increasing the feed accuracy of the feed drive mechanism. Furthermore, the rigidity of the flexible connection plate in an axial direction is high enough to drive the feed drive mechanism to be positioned precisely.
