Abstract
A power tool comprising a hollow pole, a prime mover disposed at one end of the pole, a tool disposed at the other end of the pole, a transmission shaft rotatably disposed within the pole and configured to transmit torque from the prime mover to the tool, a joint mechanism configured to support the tool such that the tool is capable of rotating with respect to the pole, a lock mechanism configured to selectively lock and unlock the joint mechanism, and a clutch mechanism disposed on a pathway of torque transmission from the prime mover to the tool via the transmission shaft, and configured to selectively connect and disconnect the pathway of torque transmission. The lock and clutch mechanisms are coupled with each other such that the clutch mechanism disconnects the pathway of torque transmission when the lock mechanism unlocks the joint mechanism.
