Claims (1)

[Scope of utility model registration request] A cylindrical blade is used in the paper perforation machine, and the paper receiving hole is directly attached to the tip of the spring (Figure 1, Figure 5) as shown in Figure 1, or the tip of the spring (Figure 2, Figure 8) as shown in Figure 2. The cylindrical part (Fig. 1, 3, 2, 9) is held so that it can rotate using the cylindrical hole (Fig. 1, 3, Fig. 2, 9) machined in the upper part of the part receiver (Fig. 2, 7) attached to the
When the cylindrical perforating blade (Fig. 1 1, Fig. 2 11) attached to the perforator rotates downward and contacts the paper after perforating the paper, a spring springs upward from below. The parts that have been pushed up rotate synchronously or in a similar state due to the friction of the cutting edge, and the cutting edge of the part and the part come to a relative stoppage, which prevents the blade from cutting or slipping. By taking advantage of zero or significant reduction, wear and tear on the blade parts due to cutting can be prevented.
In addition, the wear and tear of the pad itself is reduced, and the elasticity of the spring adjusted to the required pressure is used to provide a margin for the length of the descending distance of the blade, thereby preventing the blade tip from hitting the paper holder. A specially designed part for paper perforation.
