[0056] The control motor 45 is operated to rotate, driving the lead screw 44 to rotate on the slide frame 42, and the slide seat 43 is driven to slide in the longitudinal direction through the meshing relationship between the lead screw 44 and the threaded through hole 46, so that the slide seat 43 is away from the frame 1, and the head blank is ready to be loaded;

[0057] According to the curvature of the head blank, the angle between the connecting plate 65 and the mounting column 5 is adjusted through the limiting mechanism in the supporting assembly 6, and the adjusting bolt 62 is rotated counterclockwise to be screwed out from the threaded hole 63 on the mounting portion 52, and the adjusting bolt 62 is slid out from the through hole 69 on the first rotating shaft 64, and the limiting of the adjusting bolt 62 on the first rotating shaft 64 is released.
