The present invention relates to a nail head cutter for slate demolishment. In a cutter, a cutting head (2) formed of a pair of jaws (2a, 2a′) with a cutting blade (21) is assembled to an end of a pair of hilts (1, 1′) by hinges (10), the inside of a front end of the hilts (1, 1′) is assembled to each other by a hinge (11), and support pieces (3, 3′) are coupled to an upper and a lower part by hinges (20) to connect the jaws (2a, 2a′) forming the cutting head (2) such that the jaws (2a, 2a′) of the cutting head (2) can be closed to cut a thick steel wire or a steel wire when the hilts (1, 1′) are closed. A tip of a cutting blade (21) of the jaws (2a, 2a′) is formed as a ∠-shape, a tail of the cutting head (2) is bent at an angle of 15-45°, and a groove (22) is formed on the cutting head to bury a support piece (3′) in an undersurface of the jaws (2a, 2a′). Screw shafts (31) formed in left and right sides of a top surface of the support piece (3′) penetrate the jaws (2a, 2a′) and a support piece (3) and then are coupled by anti-releasing nuts (32); thereby preventing the protrusion of the support piece (3′) from the undersurface of the jaws (2a, 2a′). The present invention quickly and conveniently demolishes a slate roof (S). Also, the present invention minimizes a fracture ratio of the slates to minimize the scattering of asbestos as a carcinogen; thereby maximizing safety and reliability. |
