At this time, the distance between the upper portion of the first key 46a and the lower portion of the second key 46b is larger than 0.1 mm from the distance between the upper portion of the first key groove 18a and the second key groove 18b. In addition, a guide groove 48 is formed between the first key 18a and the second key 18b to accommodate the head 32 of the adjustment screw 30 exposed to the seat portion 14 side. Preferably, the upper surface of the first key 46a and the lower surface of the second key groove 46b form a first elastic inclined surface 47a and a second elastic inductive slope 47b extending narrowly from one side to the other side. do.

The following briefly describes the coupling state and the operating state of the side cutter 100 formed as described above.

First, when the coupling state is described, the adjustment screw 30 is coupled to an appropriate position using a stove (not shown) to the adjustment hole 22 formed in the partition wall 12. When the adjustment screw 30 is coupled in this way, the locator 40 is positioned in accordance with the first key groove 18a, the second key groove 18b of the seat portion 14 and the head 32 of the adjustment screw 30. Let's do it. Then, after assembling the wedge 50 to the seat portion 14, and tighten the wedge screw 52, the wedge 50 is in contact with the rocket 40 to generate a strong force (F1) (see Fig. 4) ) Force F1 is applied to the first key 46a and the second key 46b attached to the rocket 40 by the first key groove 18a and the second key groove 18b on one side of the seat portion 14. Insert it in At this time, the dimension between the first key 46a and the second key 46b is designed to be 0.1 mm or larger than the dimension between the first key groove 18a and the second key groove 18b, so that the first key 46a and The second key 46b generates forces F3-1 and F3-2 with elastic deformation along the first elastic inclined plane 47a and the second elastic inclined plane 47b, thereby providing the first key 46a and the first key. Another force (F2) in which the rocket 40 pushes the side of the seat portion 14 after making a perfect contact between the second key 46b, the first keyway 18a, and the second keyway 18b without generating a gap. -1, F2-2, F2-3) is a second generation of the rocket 40 is fixed strongly.
