Claims

[Scope of utility model registration request]

In a small engine work machine that performs trimming work by transmitting the rotational driving force of the engine mounted on the work machine body to the trimming blade mechanism at the front of the main body via a reciprocating mechanism, the trimming blade of the trimming blade mechanism is connected to the trimming blade mechanism on the front part of the main body. A small engine working machine, characterized in that it is formed by a drive connecting plate that engages with the blade main body in the thrust direction, and the thrust engaging part is provided outside the case of the reciprocating mechanism.
