Claims

[Scope of utility model registration request]

The vertically movable frame has a pair of left and right horizontal saw blades for cutting both sides near the tip of the workpiece along the width direction, and a pair of horizontal saw blades for cutting both sides near the tip of the workpiece along the longitudinal direction. For this purpose, in a tenon cutting machine in which a pair of left and right vertical saw blades are rotatably supported on both the horizontal saw blades and opposite to the horizontal saw blades, the frame is attached to the frame in order to cover the upper part of the vertical saw blades. On the other hand, there is a rear cover plate that is supported so as to be tiltable unilaterally upward, and a rear cover plate that can be tilted unilaterally forward in order to cover the upper and front areas of both horizontal saw blades with respect to the front end of the rear cover plate. Beneath the connection fulcrum with the connected front cover plate, the double force bar plate slides into contact with the upper edge of the tip of the workpiece when it moves up and down with the frame to guide the front end of the rear cover plate in the vertical direction. 1. A safety cover for a tenon cutter, characterized in that sliding contact pieces are provided opposite to each other so as to straddle the double force bar plate.
