Abstract
A boundary cutting tool includes a tool body. The tool body includes a motor, a cutting blade, and a guard. The cutting blade is configured to be driven by the motor to rotate about a first axis a. The guard covers part of the cutting blade. The cutting blade includes a mounting region having a mounting plane and at least one blade arm. The blade arm has a first curved section and a second curved section. The first curved section has a first line b, and the second curved section has a second line c. The first line b is not parallel to the second line c.
Claims20
A boundary cutting tool, comprising:
- a motor;
- a cutting blade, configured to be driven by the motor to rotate about a first axis for cutting, comprising a planar mounting region and at least one blade arm having a first curved section and a second curved section, the first curved section has a first line b, the second curved section has a second line c, and the first line b is not parallel to the second line c;
- and
- a guard covering at least part of the cutting blade.
A boundary cutting tool, comprising:
- a motor having an output shaft configured to be rotatable about a first axis to generate a driving force;
- a cutting blade, configured to be driven by the motor to rotate about the first axis for cutting, comprising a mounting region having a mounting hole so that the cutting blade is mountable to the output shaft of the motor and at least one blade arm having a free end away from the mounting region where a top end of the free end has a first side and a second side longer than the first side and the first side is basically perpendicular to a first region edge line of the mounting region;
- and
- a guard covering at least part of the cutting blade.
A boundary cutting tool, comprising:
- a motor;
- a cutting blade, configured to be driven by the motor to rotate about a first axis for cutting, comprising a planar mounting region and at least one blade arm having a free end away from the mounting region where a cutting edge is formed at the free end;
- and
- a guard covering at least part of the cutting blade.
