At this time, the tapered end of the supporting head 3 is inserted into the bottom end hole 41, and the valve core body 4 can be initially positioned. Then, the clamping head 5 is regulated by the regulating component 6 to slide in the direction close to the supporting head 3. At this time, the clamping head 5 gradually approaches the valve core body 4, and squeezes the valve core body 4 through the tapered head at its end until it is inserted into the top end hole 41. At this time, under the limitation of the supporting head 3 and the clamping head 5, the valve core body 4 can be positioned, and the valve core body 4 can be fixed relative to the supporting head 3 under the extrusion friction force of the supporting head 3 and the clamping head 5, so as to facilitate the welding of the valve core body 4 through the external welding head.
