Claims

[Claims for Utility Model Registration] (1) Rope head 16 that accommodates the rope-shaped cutting blade 20 inside, and the through hole 42 of this rope head 16
The locking body 46 is attached so that it is prevented from coming off.
and a through hole 52 formed in the locking body 46 and screwed into the rope-shaped cutting blade 20 to lead out the rope-shaped cutting blade 20 to the outside of the rope head 16. A brush cutter. (2) The rotation restraining parts 56, 58, and 64 can freely switch between restricting and allowing rotation of the locking body 46 in the circumferential direction of the rope-shaped cutting blade 20.
6 and the locking body 46. (3) The brush cutter according to claim 2, wherein the rotation restricting portions 56, 58, 64 include engaging portions 56, 58 between the rope head 16 and the locking body 46. (4) The rotation restraint parts 56, 58, 64 are the friction parts 6 between the rope head 16 and the locking body 46.
3. The brush cutter according to claim 2, further comprising: 4. (5) Used in brush cutters, with spiral striations 44 on the periphery.
60. A rope-shaped cutting blade characterized by being formed with a diameter of 60.
