Claims

[Scope of utility model registration request]

A branching machine in which a chain saw 1 is installed above a main body 3 that can be raised and lowered with respect to a tree trunk 4, and the chain saw 1 is spirally raised relative to the trunk 4 to cut branches on the way up. 1. A branch sensor 2 for preventing branch bite, which is pivoted to the upper end of the chain saw 1 with a pivot pin 6 so as to be tiltable back and forth while maintaining the tip protruding from the curved movement locus of the cutting edge at the upper end edge; A return spring 12 is interposed between the chain saw 1 and the branch sensor 2 to always return the branch sensor 2 to a predetermined forward regulating position, and the pivot pin 6 is moved from a direction perpendicular to the inner surface of the chain saw 1 opposite to the surface of the trunk 4. The branch cutting machine is provided so as to be tilted rearward, and a part of the tip of the branch sensor 2 gradually protrudes from the inner surface of the chain saw 1 toward the trunk 4 side as the tip part of the branch sensor 2 is tilted rearward from the restriction position. Chain saw branch sensor.
