The cutting blade 3 is pushed down so that 6 is substantially parallel to the upper surface of the base 21 and the cutting blade 53 is swung. In this state, the fixing bolt 45A is tightened to define the position of the stopper holder 45 with respect to the swing support portion 41. Further, by operating the restriction operation unit 28 and the clamp lever 41B, the rotation angle of the turntable 22 and the tilt angle of the cutting unit 3 are adjusted in accordance with the cutting angle of the wood W.

  Thereafter, the fixing screw 51A is loosened so that the cutting main body 5 is slidable with respect to the slide portion 6, the stopper pin 45C is pulled, the engagement between the engagement portion 45E and the recess 42b is released, and the pin 45F Is inserted in the groove 45b, the cutting part 3 is swung upward, and the cutting blade 53 is arranged on the base part 2 as shown in FIG. In this state, the wood W is placed on the base portion 2, and as shown in FIG. 8, the cutting main body portion 5 is slid forward to swing close to the base portion 2 to cut the wood W. To do.

  As shown in FIG. 4, the stopper pin 45C is slid by the biasing force of the spring 45D in a state where the cutting portion 3 is swung to a position where the slide portion 6 and the upper surface of the base portion 2 are parallel. The engaging portion 45E enters the recess 42b, and the cutting blade 53 is disposed at the cutting position. As a result, the cutting part 3 cannot swing, so that the cutting body 5 is always kept at a fixed position in the swinging direction even if the operator does not push down the handle 55 against the biasing force of the spring 44A. It is. Therefore, the cutting blade 53 can be fixed at a predetermined swing angle at which the slide portion 6 and the upper surface of the base portion 2 are parallel. Since the cutting blade 53 does not swing after being fixed, the wood W can be cut by applying a force to the handle 55 only in the direction in which the cutting blade 53 slides.

  The cutting main body 5 is slid backward as shown in FIG. 9 with the slide portion 6 and the upper surface of the base portion 2 parallel to cut the wood W. After the cutting is completed, by pulling the stopper pin 45C, the engaging portion 45E and the concave portion 42b are disengaged, and the cutting blade 53 can swing upward, which is the non-cutting position. .

When cutting, the cutting width L that can be cut by the slide of the cutting main body 5 is L, the sliding amount is n, the radius of the cutting blade 53 is 1, and the base from the center of the cutting blade 53 is shown in FIG. When the distance to the upper surface of the part 2 is m ₁ ,
L ₁ = n + (l ² −m ₁ ² ) ^(1/2) × 2
Given in. In the state where the cutting width is L ₁ , the width of the wood W: L ₁ is smaller than H, so the wood W cannot be cut. On the other hand, the adjustment knob 42A is rotated in a state where the slide portion 6 is parallel to the upper surface of the base portion 2 so that the cutting main body portion 5 is brought close to the base portion 2 and from the center of the cutting blade 53 to the upper surface of the base portion 2. When the distance is m ₂ (m ₁ > m ₂ ),
L ₂ = n + (l ² −m ₂ ² ) ^(1/2) × 2>H> L ₁ and the wood W can be suitably cut.

  Therefore, the wider wood W can be cut by bringing the cutting blade 53 close to the base portion 2. Conversely, the thickness of the wood W that can be cut with the cutting blade 53 is determined by the distance from the surface of the base portion 2 to the center of the cutting blade 53, so that it is thicker by separating the cutting blade 53 from the base portion 2. The wood W can be cut. Moreover, since the distance from the cutting blade 53 to the base part 2 can be changed arbitrarily, even if the cutting blade 53 is a small diameter, it can cut suitably from the thick wood W to the wide wood W.
