When the processing of the inclined surface of an art work piece is desired, the moving jaw(4) is moved toward the screw strut(2). Insert the range adjusting bar(15) into the rotary work hole(14a) provided at the front of the fixed jaw(3). Moving it to the desired direction, a worm axle(13) and the worm wheel(12) interlocked, rotate little by little, and the angle of the inserting dent changes. Then the worker can view the coincidence of the scale(14b) of the angle adjusting plate(14) with the standard scale(3b) by handling the range adjusting bar(15). Therefore, angle adjustment is becomes easier and fine angle adjustment is made possible.
