A cutting device for partially cutting 103.

This cutting device includes a base 1, a holding member 2, and a first tool 3
And a second tool 4 and an air press device 5.

Two guide rods 10 and 11 are fixed to the base 1 so as to extend in parallel with the driving direction of the air press device 5, respectively. An air press device 5 is fixed to the base 1 at one end side of the guide rods 10 and 11. Further, a lid member 12 is swingably held by a hinge 13 on the base 1,
As shown in FIG. 1, 12 is configured to be able to press the work 100 toward the holding member 2. A magnet 14 is fixed to the base 1 so that the lid member 12 is attracted and held at the closed position.

The holding member 2 includes a holding portion 20 and an intermediate blade 21.
Is fixed to the holder 20. The holding member 2 is pivotally supported by guide rods 10 and 11 so as to be slidably movable. Then, the intermediate blade 21 projects upward from the holding portion 20, and the guide rod 1
It has a plate shape extending in a direction perpendicular to the axial directions of 0 and 11.

The first tool 3 includes a first holder 30 and a first cutting blade 31 held by the first holder 30. First holder 30
Is fixed to the tip of the piston rod 50 of the air press device 5 and is pivotally supported by the guide rods 10 and 11 so as to be slidably movable. Further, the second tool 4 includes a second holder 40 and a second holder 40.
The second holder 40 is fixed to the base 1. The first cutting blade 31 and the second cutting blade 41 are U-shaped Thomson blades having the same shape, and face each other so that their cutting edges face each other.

The air press device 5 is a commercially available device, and the cutting device of this embodiment is a modification of the tip portion of the air press device 5.

A first spring 22 and a second spring 23 are attached to the guide rods 10 and 11, respectively. Both ends of the first spring 22 are locked by the first holder 30 and the holding member 2, and both ends of the second spring 23 are locked by the second holder 40 and the holding member 2. Namely the guide rod 10,
