Crimping plier

A crimping plier, used for crimping a telecommunications connector, the crimping plier comprising:

• a clamp handle mechanism, comprising a first clamp handle and a second clamp handle pivoted to each other;
• a crimping mechanism, comprising:
• a main body, disposed on a top end of the clamp handle mechanism, the main body having a terminal accommodation portion;
• a crimping tooth member, movably disposed on the main body, one end of the crimping tooth member having a tooth-shaped structure, the tooth-shaped structure corresponding to the terminal accommodation portion;
• a crimping member, movably disposed on the main body, the crimping member having a flat end, the flat end corresponding to the terminal accommodation portion and being positioned in a first position or a second position;
• and
• a clamp set, having a first concave portion and a second concave portion, the first concave portion being disposed on the first clamp handle and the second concave portion being disposed on the second clamp handle;
• and
• a driving mechanism, disposed between the first clamp handle and the second clamp handle, the driving mechanism comprising:
• a first connecting rod with one end connected to the first clamp handle and the other end connected to the crimping tooth member and the crimping member;
• and
• a second connecting rod with one end connected to the second clamp handle and the other end connected to the crimping tooth member and the crimping member;
• wherein when the first clamp handle and the second clamp handle move toward each other, the first connecting rod and the second connecting rod push the crimping tooth member and the crimping member such that the tooth-shaped structure of the crimping tooth member enters into the terminal accommodation portion, and the flat end of the crimping member selectively enters into the terminal accommodation portion such that the first concave portion and the second concave portion close to jointly form a circular structure,
• wherein when the flat end of the crimping member is positioned in the first position and the first clamp handle and the second clamp handle move toward each other, the flat end enters into the terminal accommodation portion, and
• when the flat end of the crimping member is positioned in the second position and the first clamp handle and the second clamp handle move toward each other, the flat end is located outside of the terminal accommodation portion.
