できる。(Operation) As described above, the main needle 11 and the coupling 13 are directly screw-joined to each other, and the coupling 12 is sandwiched between the two.
Moreover, since the threaded joint between the main needle 11 and the coupling 13 is formed by thermite welding, the threads of both are melted and become the same body, so that the conventional problems can be eliminated.

するだけでもよい。(Embodiment) FIG. 2 is a sectional view showing an embodiment of the projecting needle of the present invention. As shown in the figure, 11 is the main needle itself, and the stepped portion 11a is at the bottom.
And a threaded portion 11b is provided at the lower end thereof. Reference numeral 12 is a coupling connecting portion, which is provided with a through hole into which the step portion 11a is fitted. 13 is a coupling, which is the stepped portion
After inserting 11a into the coupling connecting portion 12, an internal thread for screwing with the threaded portion 11b of the main needle 11 itself is provided. The toothed washer 14 is inserted between the coupling 13 and the coupling 13 so that the coupling 12 does not rotate.

る。Next, the side surface of the coupling 13 is provided with a through hole 13a for thermite welding and a pedestal portion 13b for mounting the mold 15 for installing the thermite capsule. Note that thermite welding is mainly composed of copper oxide and aluminum copper powder, and in addition to this, a mixed powder added with some flax to improve performance is ignited and burned, causing a thermite reaction and melting. The copper alloy and the metal to be welded are melted by utilizing the reaction heat, and they are completely integrated to form an alloy structure and bond.
