When replacing the clamping head 5, press the paddle 21 downward, and the paddle 21 descends to drive the movable rod to descend, and then drive the supporting block 19 to descend.

After the extrusion is completed, the support plate 11 is pulled out by pulling the pulling column 12. The traction column 10 pulls the first clamping block 7 open under the pull of one side of the square groove at the top of the support plate 11, and releases the clamping limit of the RF coaxial connector, so that the RF coaxial connector falls into the storage slot of the storage box 13, and then the residue is collected.
