Abstract:

A new and improved remote trigger actuating mechanism for a power tool comprises an elongated handle or pole which is provided with a handgrip upon a rear end portion, while a mounting bracket, into which a forward end portion of the elongated handle or pole is fixedly engaged, is fixedly mounted upon a rear end portion of the power tool as a result of being bolted directly thereto by suitable bolt fasteners. A spring-biased sleeve member is concentrically disposed about the elongated handle or pole, and a trigger actuator linkage member has a rear end portion thereof fixedly mounted upon the spring-biased sleeve member while a forward end portion of the trigger actuator linkage member is provided with a hooked portion which is adapted to engage the trigger mechanism of the power tool. The spring-biased sleeve member is normally biased to a forward extended position by a coil spring such that the trigger actuator linkage member does not normally engage the trigger mechanism of the power tool, however, when the spring-biased sleeve member is manually moved in the rearward direction against the spring-biasing force of the coil spring, the trigger actuator or linkage member will engage and actuate the trigger mechanism of the power tool whereby the power tool will be energized.
