The present design relates to reporters woodworking angle geumgeut easily perform angle measurement and marking-off, the cutting operation of corners, edges, such as by bar wings to rotate left and right interior carpentry work when the body bar tip, more specifically, the upper lengthwise in accordance with the body bar (10) forming the grid, 'and a stem (25, 25 described above, the left and right wings of the body bar front end left and right wings are hinged to rotate in the opposite right and left on the bar 20 20') at both ends but the left and right wings are connected by a hinge bar 20 (20 ') coupled to move the slide back and forth along the length of the bar to the body for measuring the angle scale by rotating the left and right portions in accordance with the syntax of the configuration (30); Push, which is installed so as to retracting the elastic to the body bar 10, a bottom bar (50) is first formed an extension portion 51 that extends forward of the body bar to the front, and installed up and down of the push bar (50) 1 a spring (60) and intended to be used infestation by moving Multan second spring (70) back and forth up and down and the body bar by being installed around the longitudinal hameuroseo a corner by the bar blades to rotate left and right in the interior during carpentry work body bar tip angle, such as the edge measuring and marking-off gold easy haenghadoe, especially in bars push to Tan infestation in the bar lower body during the molding cutting operations improved structures, so haunting to the front of the body bar base is compact electric saws cutting machine cutting operations solve the problem of difficulty in the case of a conventional installation and will have the effect to further maximize the operability, efficiency.
