Abstract
A control handle included in a bush cutter is provided. A driving controller is switched on so that the cutting blade is driven in an adjusted speed mode at a rotation speed set by a speed adjuster. The control handle includes a high-speed mode controller configured to set the rotation speed of the cutting blade to a high rotation speed, and an interlock device provided between the driving controller and the high-speed mode controller and configured to interlock the driving controller and the high-speed mode controller when the high-speed mode controller is switched on so as to move the driving controller concurrently with the high-speed mode controller. When the high-speed mode controller is switched on, the driving controller is concurrently switched on by the interlock device so that the cutting blade is driven in a high-speed mode.
