Claims

[Scope of utility model registration request]

A power source is provided at one end of a long main rod, and a cutting blade rotated by a transmission shaft penetrating the main rod and a spindle supported by a gear box is provided at the other end. In a brush cutter that is held between side blade seats and screwed to the tip of the spindle via the lower cutting blade catch, a substantially cylindrical member that surrounds the head of the fastening member is attached to the lower cutting blade catch. The protrusions are integrally molded,
A spindle lock structure comprising two parallel faces formed on the outer periphery of the cylindrical protrusion and a wrench applied to the two parallel faces to suppress rotation so that the fastening member can be tightened and loosened when attaching and removing the cutting blade. .
