The present invention relates to a precise sliding angle adjustment device which can perform a cutting work in a state of being fixed without any wavering, and can adjust horizontality easily during the cutting work of a workpiece (section steel, structural steel, round bar, pipe etc), and can transfer the workpiece easily, and can prevent chips from being scattered to a worker, and can cut the workpiece precisely, safely and conveniently, and also can perform the cutting work in an accurate dimension, and can improve productivity of the cutting work remarkably. The precise sliding angle adjustment device of the present invention includes: a main base (900) comprising an angle magnetic scale (200), an angle groove (240) and a water drop leveler (960); a height adjustment ruler (700) which raises or lowers the main base (900) by being installed at one side of the main base (900); a base adjustment spring (710) which is located on a bottom of the main base (900), and adjusts height of the main base (900) by surrounding the height adjustment ruler (700); a base adjustment support (720) to support the height adjustment ruler (700); a base fixing handle (730) to fix the main base (900); a rotation plate (260) which is rotatably installed on an upper plane of the main base (900), and comprises an accommodation groove to accommodate a cutting blade; and a digital angle display unit (210) which is installed at one side of the rotation plate (260) and displays a rotation angle of the rotation plate (260). |
