Problems solved by technology

[0003] However, the existing punching machine is only for double-hole punching. This kind of double-hole punching machine is limited by its appearance, so that it cannot get enough force arm, and cannot achieve the effect of labor-saving pressing. Not only that , the distance between the two punching positions cannot be changed, which increases the restrictions on use, and can only punch holes for a small amount of paper in use. For the above problems, it is urgent to improve
