Claims

[Scope of utility model registration request]

A casing that is driven by a press machine and can move toward and away from the work; a block that is slidably provided within the casing and can move toward and away from the work; and a punch for machining the work that is attached to the block. A biasing means provided within the casing that constantly biases the block and punch to a non-operating position away from the workpiece, and an actuation mechanism that moves the block and punch closer to the workpiece against the biasing force of the biasing means. A punch position switching structure characterized by comprising: a driving means for positioning the punch in a certain position.
