Hin- und herbewegliches Werkzeug mit einem Hubeinstellmechanismus

摘要

A reciprocating acting tool includes a disc 20 rotatably received in a housing and a shaft 14 slidably engaged in the upper portion of the housing. The disc includes a bolt 30 rotatably engaged in a groove and a slide 28 threadedly engaged with the bolt. The slide includes a stud 281 for rotatably supporting a follower 29 which is slidable engaged with a notch 15 in the shaft. The slide is moved longitudinally along the groove so as to adjust the stroke 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. The shaft 14 is formed with an internal thread 16 at one end to engage a tool.
