Novel bevelling machine knife rest

The utility model provides a novel bevelling machine knife rest. A machine body is fixed to a machined workpiece through four machine body fixing screw rods which are evenly distributed in a circumference mode. An annular gear is arranged inside the machine body and driven by a drive device. Two knife rest bodies are symmetrically arranged on the machine body. The annular gear drives the two knife rest bodies to conduct circular motion at an equal speed. The novel bevelling machine knife rest further comprises a hinge type turning tool clamping and holding device which is provided with a fixed end and a free end which are hinged to each other. The fixed end can be fixed to the knife rest bodies or can move on the knife rest bodies in a horizontal and radial mode. The free end clamps and holds a turning tool which can slide vertically along the free end. Grooves of any angles can be machined only through one or two kinds of turning tools instead of using turning tools of different angles to conduct groove turn
