Betätigungsmechanismus für die untere Sägeblattschutzvorrichtung einer Gleitverbund-Gehrungssäge

摘要

A saw includes a base having a turntable for movement about a vertical axis, a support member 626 mounted on the turntable, and a saw arm mounted on the support member for pivotal movement about an axis between cutting and non-cutting positions. The saw blade is mounted for rotation about an arbor axis. A lower blade guard is supported on the saw arm for pivotal movement about the arbor axis between a surround position and a non-surround position. A cam plate 642 is mounted on the saw arm, and a cam follower 638 mounted on the support member 626 such that movement of the saw arm between the non-cutting position and the cutting position causes pivotal movement of the lower blade guard between the surround position and the non-surround position. A torsion spring 674 biases the guard to the surround position.
