A safety cutter for jam prevention for preventing an object being cut from being jammed when the direction of a disc-shaped rotary cutting member is switched especially in a diagonal or curved line, as well as cutting the object while the disc-shaped rotary cutting member is traversing and rotating about a center of the object being cut by means of simple pushing force without needing scissoring. The safety cutter includes a cutter body, disc-shaped rotary cutting members, and fastening members. In the cutter body, an open slit is formed on the front of the cutter body, coupling holes are respectively formed on the top and bottom of the open slit, and a grip part is formed on the rear of the cutter body. |

1. An anti-jam safety cutter comprising:
a cutter body which includes an open slit formed in the front thereof, coupling holes formed at the top and bottom of the open slit, respectively, and a grip portion provided at the rear thereof; disc-shaped rotary cutting members which are rotatably connected to the top and bottom of the front of the cutter body, respectively, and which include central holes formed in the center thereof to communicate with the coupling holes of the cutter body, insertion holes spaced in the radial direction from the central holes, and cutting blades formed on the edges thereof to protrude through the open slit and overlap each other; and fastening members which rotatably connect the disc-shaped rotary cutting members to the top and bottom of the front of the cutter body, respectively, and which include central coupling protrusions provided in the center thereof to be sequentially inserted and coupled to the central holes of the disc-shaped rotary cutting members and the coupling holes of the cutter body, and anti-jam insertion protrusions provided at the outside in the radial direction to be inserted and fixed to the insertion holes of the disc-shaped rotary cutting members to prevent an object to be cut from being jammed when the cutting direction is changed. |
