Effort-saving paper punch

An effort-saving paper punch which comprises

• a base with a plurality of punching holes disposed towards a punching end;
• a plurality of spring-loaded punching members disposed corresponding to the plurality of punching holes;
• a pair of vertical supports mounted on the base;
• a lever pivotably connected to the pair of vertical supports by means of a lever pivot to pivot between a resting position and a punching position, and the lever pivot is fixed in position in relation to the lever;
• characterized in that:
• a lever pivot slot is provided at each of the vertical supports for receiving the lever pivot in a way which enables the lever pivot to move towards the punching end in the resting position and away from the punching end in the punching position;
• a longitudinal contact member is fixedly disposed underneath the lever at a position corresponding to the punching members so that a first end of the longitudinal contact member which is farther away from the punching end abuts against the punching members in the resting position;
• and as the lever pivots from the resting position to the punching position, the first end of the longitudinal contact member moves farther away from the punching end until a second end of the longitudinal contact member which is nearer to the punching end abuts against the punching members in the punching position.
