The invention relates to a specially-used universal knife which mainly comprises a side baffle. The upper portion and the left side of the side baffle are connected with an upper connecting base and a side connecting base in a surface welding mode respectively. A fixed ring with an internal thread is arranged at the center of the side baffle, and a rotating ring is arranged on the outer side of the fixing ring in a sleeving mode. A drill bit, a cutting knife head and a balance beam are sequentially arranged at the front end of the outer side face of the rotating ring in the circumferential direction, and a circle of wheel teeth are arranged at the rear end of the outer side face of the rotating ring. A turnburkle which can lock the rotating ring on the outer circle of the fixed ring is arranged on the upper portion of the outer side face of the rotating ring. A gear which is meshed with the wheel teeth is arranged on the right side of the rotating ring, and the gear is axially connected with a motor which is mounted on the side baffle. One side of the portion under the side baffle is sleeved with an H-shaped bolt, and the front side face of the rear end of the H-shaped bolt is fixedly connected with springs mounted on the inner side face of the side baffle. The specially-used universal knife is high in automation degree, so that knives are quickly switched, and the stability of drilling and cutting work is improved.
