  When the gripping part 1 is gripped, the rotating body 4 is located at a position where it can be operated with the fingers of the hand gripping the gripping part 1, so that the rotating body 4 can be rotated with the fingers of the hand. .

  When the rotating body 4 is rotated in one direction, the facing distance between the pair of supporting arm portions 2 is maintained at the wide distance L1 by the wide / narrow switching mechanism 4, and the replacement blade body 3 is not supported. The replaceable blade body 3 is in a removable state.

  When the rotating body 4 is operated to rotate in the other direction from the state in which the wide distance L1 is maintained, the facing distance between the pair of support arm portions 2 by the wide / narrow switching mechanism 4 becomes the narrow distance L1 at which the replaceable blade body 3 can be sandwiched and supported. It will switch to the state to maintain.

  Therefore, the rotating body 4 can be easily operated with the finger of the hand (one hand) holding the gripping part 1, and the rotating operation with the finger can be easily performed. Since the facing interval between the arm portions 2 can be easily switched between a wide interval L1 at which the replaceable blade body 3 can be attached and detached and a narrow interval L2 at which the replaceable blade body 3 can be held and held, the replacement operation of the replaceable blade body 3 is extremely difficult.

  Further, for example, the rotating body 5 is formed by screwing both end portions in a direction orthogonal to the rotating direction to the respective base side sides of the pair of support arm portions 2, thereby connecting the base side sides of the pair of support arm portions 2. In a state of being installed in a freely rotating manner, the opposing distance between the pair of supporting arm portions 2 is set by the screw advance operation or screw retract operation when the rotary body 5 is rotated in one direction. The distance between the pair of supporting arm portions 2 can be set to the narrow distance L2 by the screwing-in / out operation or the screwing-out operation when the rotating body 5 is rotated in the other direction. If the wide / narrow switching mechanism 4 is configured so that it can be maintained in a state, the opposing distance between the pair of support arm portions 2 can be reliably set to the wide distance L1 and the narrow distance by a simple operation of rotating the rotating body 4. The wide and narrow switching mechanism 4 that switches to L2 can be easily designed and realized.

  In addition, for example, the one having the replacement structure of the replaceable blade body as in Patent Document 1 has a problem that if the support arm portion is deformed so that the pair of support arm portions are opened for some reason, the support arm is quite difficult. However, in the case of the wide / narrow switching mechanism 4 having such a screw advance / retreat structure, the pair of support arm portions 2 are slightly deformed.
