Abstract
A clutch safety switch of a power chainsaw includes a safety member slidably connected to the casing and a trigger which is not able to be squeezed when the safety member is not slid away. A gear connected to the power source has engaging recesses and a clutch device member is rotatably mounted to an output shaft which is independent from the gear. A link is connected between the safety member and a plate connected to the clutch member which is rotated to engage the output shaft with the gear by sliding the safety member. A lever is connected to the plate which is pivoted by pushing the lever to allow the link to move in a horizontal portion of an L-shaped slot in the plate to make the safety member be pushed back to disengage the clutch device from the gear to release the connection.
