The metal sleeve 31 includes a positive electrode rod 33 capable of performing a compression operation and a negative electrode rod 34 having a recess. It is located in between. A heating electrode 35 is connected to the positive electrode rod 33, and the positive electrode rod 33 is configured to generate heat when a current is passed between the positive electrode rod 33 and the heating electrode 35. .
