摘要：
A spring support which receives one end of a needle spring to urge the needle in a reset direction is free to move forwards or backwards. During assembly the spring support is disposed in the top end direction of the needle such that the needle is stable at the inserting state of the top end in the needle guide, after completion of the assembly the spring support is moved rearwards and fixed, and the needle is supplied with a restoring force by compression of the needle spring.
