Pliers for compression connecting a connector for a telephone line

A pair of pliers for compression connecting a connector for a telephone line, comprising:

• a pair of handles pivotably joined by a pivot pin;
• a working section is provided near the pivot pin, said working section includes a compression connecting seat fixedly mounted on one of the handles, an other one of the handles is mounted on said working section with a compression connecting block, said compression connecting seat is provided on a main body of said working section with a receiving seat to receive a telephone line connector, and a guiding groove for guiding vertical insertion of said compression connecting block therein;
• said compression connecting block is connected with a limiting pin which is inserted in a limiting hole in the other one of the handles, said limiting hole is beveled away from said compression connecting seat and said pivot pin, so that a lower edge of said limiting hole is used by said limiting pin to push said compression connecting block away from said receiving seat;
• and
• said limiting hole is a triangular shape, the upper edge of said limiting hole includes an abutting edge beveled relative to a push guiding edge thereof, so that when said abutting edge contacts and presses said limiting pin, a contact point therebetween is located besides the center of said limiting pin towards the direction where an action force is directed to, thereby a component force of a resisting force from the center of said limiting pin towards said contact point of said abutting edge with said limiting pin is at the same side as that of said action force, so that a horizontal component force of said action force is reduced, and a larger vertical force is obtained for compression connecting said compression connecting connector.
