Abstract
A reciprocating acting tool includes a disc rotatably received in a housing and includes a shaft slidably engaged in the upper portion of the housing. The disc includes a bolt rotatably engaged in a groove and a slide threadedly engaged with the bolt. The slide includes a stud for rotatably supporting a follower which is slidably engaged with the shaft. The slide is moved longitudinally along the groove so as to adjust a moving stroke and a moving speed of the shaft. The shaft is moved quickly for driving a cutting tool and is moved slowly for moving a saw blade or a file.
