ABSTRACT:
A throttle trigger device for an internal combustion engine of a working tool has a throttle trigger connected to the handle of the working tool so as to be pivotable about a pivot axis. A throttle trigger lock is connected to the handle of the working tool so as to be pivotable about a pivot axis. A spring is connected between the throttle trigger and the throttle trigger lock. The throttle trigger, the throttle trigger lock, and the spring form a unitary part. The spring rests at an abutment of the handle at least when under load such that the spring is divided into functionally independent sections, whereby a first section extends between the abutment and the throttle trigger and a second section extends between the abutment and the throttle trigger lock.
