First Claim
1. Electric scissors comprising:
- a first blade including a cutting edge portion and a transmission portion, and rotatably supported by a shaft serving as a fulcrum;
a second blade including a cutting edge portion and a transmission portion, wherein an object between the first blade and the second blade is cut by closing the first blade and the second blade;
a toggle link mechanism including a first link, a second link, and a drive shaft; and
a drive section,wherein one end of the first link is rotatably connected to said transmission portion of the first blade,one end of the second link is rotatably connected to said transmission portion of the second blade,the other end of the first link is rotatably connected to the other end of the second link through the drive shaft, andthe drive section is configuredto close the first blade and the second blade by displacing said drive shaft in a direction of increasing an angle between the first link and the second link, andto open the first blade and the second blade by displacing said drive shaft in a direction of decreasing said angle between the first link and the second link.

Abstract
Electric scissors (1A, 1B) is provided with: a first blade (2A, 2B); a second blade (3A, 3B); a toggle link mechanism (7A, 7B) including a first link (71A, 71B), a second link (72A, 72B), and a drive shaft (70A, 70B); and a drive section (5, 6). One end of the first link (71A, 71B) is rotatably connected to a transmission portion (21A, 21B) of the first blade (2A, 2B). One end of the second link (72A, 72B) is rotatably connected to a transmission portion (31A, 31B) of the second blade (3A, 3B). The other end of the first link (71A, 71B) is rotatably connected to the other end of the second link (72A, 72B) through the drive shaft (70A, 70B). The drive section (5, 6) is configured to open/close the first blade (2A, 2B) and the second blade (3A, 3B) by displacing the drive shaft (70A, 70B) in a direction perpendicular to an axial direction of the drive shaft (70A, 70B).
