1. Brake device of paper cutter
        In order to save manufacturing costs, some paper cutter manufacturers use the principle of circuit braking. This device may cause extremely dangerous conditions such as "sliding knife" in the event of sudden power failure, loose socket, and sensor failure. Therefore, when purchasing a paper cutter, purchase a product that uses a motor assembly with a mechanical brake device, so that no matter what circuit malfunctions, the motor is locked and no danger will occur.
        2. During the actual use of the paper cutter, two people are generally required to cooperate. This requires the cutter to be equipped with front and rear safety covers. When the safety cover is opened, the motor will not move to ensure safety.
        3. The operating principle of the double button of the paper cutter
        This requires the two buttons to be pressed at the same time, otherwise the cutter motor will not move, which can guarantee the absolute safety of single-person operation.
        4. When replacing the blade for the paper cutter, be sure to use the knife holder to ensure that the blade edge is closed, which not only ensures the safety of the person, but also ensures that the blade is not damaged. In addition, the removed blades must not be left at will to avoid hurting people.
