Abstract
A locking device for a spline shaft of a brush cutter is disclosed. The brush cutter comprises the spline shaft installed in a shell and coupled with a driven bevel gear that is coupled with a drive bevel gear, which is further linked to a power device. The spline shaft has a blind hole, and the shell has a stub tube facing to the blind hole. A spring and a pin are received in the stub tube in such a way that the pin is inserted through the spring and the spring acts on the pin. With this structure, when a cutting tool is to be assembled to or disassembled from the spline shaft, it is only needed to push the pin into the blind hole of the spline shaft to restrain the spline shaft from rotating. Accordingly, the cutting tool can be assembled or disassembled in safe and convenient.
