The rear end of the crystal head is equipped with a sheath front end bracket, and the rear end of the sheath front end bracket is injection-molded with a sheath. The two ends of the wire pass through the corresponding sheath and the sheath front end bracket and are electrically connected to the corresponding crystal heads. Currently, when injecting the sheath at the rear end of the sheath front end bracket, it is first necessary to assemble the sheath front end bracket to the mold base, and then manually place the mold base into the injection mold, and then the injection molding machine can injection mold the sheath on the rear end of the sheath front end bracket. After the injection molding is completed, the staff takes the mold base out of the injection molding machine, and finally manually removes the sheath front end bracket after the injection molding of the sheath from the mold base.
