PURPOSE:To simply set holding force against a gold wire by adjusting elasticity of a compressed coil spring by an adjusting screw. CONSTITUTION:With a gold wire 2 held by a movable arm 3 and a thin plate arm 6, the thin plate arm 6 is pressed by a compressed coil spring 13 and the gold wire 2 is elastically held by both arms 3 and 6. This elasticity can be set to a specific value by adjusting screwing amount of a screw 12. Though the thin plate arm 6 returns to the original position when the movable arm 3 is released, its displacement is positioned by a stopper 14 and further its vibration can be immediately weakened by elasticity of the stopper 14. Thus wire holding force can be maintained without damaging or flattening the gold wire. |
