PROBLEM TO BE SOLVED: To make an abutment body very simply and rapidly determine an acute angle that is a desirable angle to a cutting object with respect to a guide body that is another constituent member.SOLUTION: One end 4a of an abutment body 4 closer to a guider 1 is provided in projection with a turning pivot 5, and the other end 4b is fitted with an angle adjustment slider 6 projecting on the top face of a pressure plate 2 through a slender guide window hole 7 provided inside the pressure plate 2. An angle graduation display part 9 with the display of an angle scale 8 and a gradient graduation display part 11 with the display of a gradient scale 10 are displayed in a circular arc form on the top face 2c of the pressure plate 2 extending from the abutment body 4 to the guider 1 with the scale, and a window hole 12 is formed in a vicinity of the angle graduation display part 9 and the gradient graduation display part 11.SELECTED DRAWING: Figure 1 |
