摘要：A drive mechanism for a power tool having a housing, a motor, and an output shaft moving in a reciprocating motion. The drive mechanism compris a gear plate ()adapted to rotate about a first axis (Z-Z) and having a plurality of elongate first teeth ()extending perpendicular to the first axis; and
a drive conversion mechanism cooperating
with the gear plate () to cau reciprocating movement of the output shaft in respon to rotation of the gear plate about the first axis. Conventional drive mechanisms having an output shaft with a reciprocating motion generally have bevel gears with teeth formed at 45° to the axis of rotation of the gears. By providing a gear plate and a drive conversion mechanism which provides a reciprocating drive force for an output shaft with teeth formed at 90° to the axis of rotation of the gear, the gear is cheaper and easier to make as the gear teeth do not have to be formed as accurately as prior art inclined gear teeth. Also, the gear plate does not need to be as accurately located relative to the gear driving it, since some longitudinal movement in the direction of the mutually engaging teeth is possible without the gears ceasing to function correctly.
