An adjustment lever 15 for adjusting the movement of both casings 4 and 5 is attached to a support portion 3a projecting from the right side of the head body 3 so as to be rotatable about a bolt-shaped support shaft 14. . The adjustment lever 15 has a first vertical hole 16 formed at one end (lower end in FIG. 1), and a bolt-shaped first bolt screwed into the first casing through the first vertical hole 16.
The first casing 4 is connected to the first casing 4 by a connecting pin 17 . Note that 18 is a knob attached to the other end of the adjustment lever.

On the upper surface of the head body 3, there is an L-shaped interlocking member 19 that moves the second casing 5 in conjunction with the adjustment lever 15. , 20, and is attached to the head body 3 by tightening bolts 21, 21 screwed into the head body 3 so as to be movable in the left-right direction. Further, the interlocking member 19 has a connecting piece 19a formed at a right angle at one end thereof (the left end in FIG. 1), and the distal end thereof is connected to the second casing 5 by a pin 22. In addition, interlocking member 1
The other end of the adjustment lever 9 extends perpendicularly to the other end of the adjustment lever 15, and a grip portion 19b is bent at the tip thereof as shown in FIG. At the intersection of the interlocking member 19 and the adjustment lever 15, the interlocking member 19 connects to the second vertical hole 23 and the second bolt-shaped
It is detachably connected to the adjustment lever 15 by a connecting pin 24. The second connecting pin 24 has a threaded portion 24a passing through the interlocking member 19, and is fixed at a predetermined position on the interlocking member 19 by a nut 25 screwed into the threaded portion 24a. The head 24b of 24 is removably engaged with the second vertical hole 23 formed in the adjustment lever 15. Moreover, the adjustment lever 15 is connected to the interlocking member 19.
The head 24 of the second connecting pin 24 and the adjustment lever 1

Only the casing 4 moves.

When only the second casing 5 is moved, the adjustment lever 15 is elastically deformed into a curved shape as described above, and the second vertical hole 23 and the second connecting pin 24 are disengaged. By moving the member 19, only the second casing 5 is moved.

(Effects of the invention) That is, according to this invention, both the first and second casings can be moved simultaneously by a simple operation of rotating the adjustment lever about the pivot point at the almost central part of the adjustment lever. The movement of the saw blade can be adjusted quickly and easily. Further, since the device is mainly composed of two members, the adjustment lever and the interlocking member, the structure is simple and the number of parts can be minimized, thereby reducing costs and assembly man-hours.

Furthermore, since the adjustment lever is detachably connected to the other end of the interlocking member by the connecting pin and the vertical hole, the adjustment lever and the interlocking member can be connected in a state where the connecting pin and the vertical hole are detached. The movement of both the first and second casings can be adjusted independently by operating each of them independently.

In particular, according to this invention, the engagement and disengagement between the interlocking member and the adjustment lever when the first and second casings are moved independently is achieved by elastically deforming the adjustment lever formed from a spring plate material into a curved shape. This has the advantage that it can be easily and quickly removed by separating the connecting pin and the vertical hole.
