  The movable operation unit 14 is not mechanically interlocked with the blade body 18, for example, every time the switch is turned on / off, for example, every time the push button switch is pressed, an electrical signal is sent from the switch so that the blade body 18 is moved to a predetermined angle. You may make it rotate (for example, 5 degree | times, 10 degree | times, 15 degree | times, etc.).

  As shown in FIGS. 6 (a) and 6 (b), in the upper and lower side blade plates 19 and 20 of the blade body 18, the reinforcing plate portions 36 are opposed to each other from both sides in the width direction Y in the vicinity of the upper and lower side blade edges 19a and 20a. Then, when the upper and lower side blade edges 19a and 20a are brought into contact with each other, the reinforcing plate portion 36 may suppress bending of the upper and lower side blade plate portions 19 and 20 to maintain the sharpness. . Note that the same reinforcing plate portion 36 may be formed on only one of the upper and lower side blade plate portions 19 and 20.

  7A and 7B, in the upper blade plate portion 19 of the blade body 18, a plurality of convex portions arranged in the width direction Y below the upper blade plate portion 19 in the vicinity of the upper blade edge 19a. A reinforcing rib 37 having 37 a and a plurality of concave portions 37 b arranged in the width direction Y on the upper side of the upper blade plate portion 19 may be formed. Further, as shown in FIGS. 8A and 8B, in the upper blade plate portion 19 of the blade body 18, a ridge 38a extending in the width direction Y below the upper blade plate portion 19 in the vicinity of the upper blade edge 19a. A reinforcing rib 38 having a groove 38b extending in the width direction Y on the upper side of the upper blade plate portion 19 may be formed. When the upper and lower blade edges 19a and 20a are brought into contact with each other, the reinforcing ribs 37 and 38 can suppress the bending of the upper blade plate portion 19 and maintain the sharpness. Similar reinforcing ribs 37 and 38 may be formed on the lower blade plate portion 20 of the blade body 18. For example, these reinforcing ribs 37 and 38 are integrally formed with the blade body 18 by pressing.
