The interval between the upper part and the lower part of the clamping part is provided with a smooth transitional surface. The smooth transitional surface is arranged above the limiting wheel; two guide grooves are opened symmetrically and fixed on the frame, and the clamping parts are respectively arranged on the two guiding parts. In the groove, a foot beam is hinged between the lower ends of the two clamping pieces; a fixed beam is relatively fixed on the frame, and a fixed beam is provided between the fixed beam and the foot beam. Spring; a step driving means is provided with feet on the beam. The utility model is simple in structure, convenient in manufacture and high in production efficiency, and can be used as an auxiliary for the whole package which needs to be compressed after the press-down clamp presses the pillow core deformation set between the press pillows and fits into the head pillow. Packaging device use.
