Abstract: A guide and flattening mechanism includes a mounting seat having a support plane and an elastic guide assembly arranged at the mounting seat and having an inclined surface. The inclined surface is arranged around a central axis perpendicular to the support plane and is located on a side of the elastic guide assembly facing away from the support plane. From a side of the inclined surface close to the central axis to a side of the inclined surface away from the central axis, at least a part of the inclined surface is arranged obliquely in a direction away from the support plane. The inclined surface is configured to be elastically deformed in a direction approaching the support plane when being squeezed, so as to guide the bending of the to-be-flattened member and flatten the to-be-flattened member on the circular end surface with the cooperation of the support plane.
