However, for details, see the work shown in Figure 2 and Figure 3.
At an intermediate position of the drive part 1, a VC rotation fulcrum 8 is provided in the opposite direction to the blade part, and the grip 5 and the drive part 1 are rotated by 50%.
As shown in the figure, it is rotatably fixed with a screw n via a nut 21 and a washer 22. This nut 21 corresponds to the rotation fulcrum 8. That is, as shown in FIG.

A retaining portion a of the drive portion 1 is provided within the pair of engaging portions 5′ of the grip 5.
', align the hole 5a on the grip 5 side with the hole a on the drive unit 1 side, and insert the rotation fulcrum nut 21 from the outside into the holes 5a and a, and then Washer 22 from the side. A screw 23 is provided to rotatably connect the grip 5 and the drive unit 1 side. The lock button 24 is provided in the grip 5; the lock button 24 is pressed in the longitudinal direction of the L flip 5 when the spring is pressed. Engaged to lock n1 rotation. As shown in the second factor, the retaining part of the retaining part 26 is provided at the 3PM location, and the first retaining part 26 a
The grip 5 is held in a half-line state with the blade part. Then, by moving the lock button 24 in the opposite direction to the blade part against the spring 25, the engaging part of the lock button 24 is disengaged from the first engaging part 26a, and the lock is released. By rotating the grip 5, the other second. Third engaging portion 26
