Capillary tube pliers

A capillary tube plier, comprising:

• a first clamping arm;
• a second clamping arm, wherein first pivot portions are formed by extending oppositely to each other from a first end of the first clamping arm and a first end of the second clamping arm respectively, and the first pivot portions are connected by a first pivot axis for allowing the first and second clamping arms to rotate relative to each other;
• a first pressing portion, provided at a second end of the first clamping arm, protruding towards the second clamping arm and forming a first pressing surface;
• and
• a second pressing portion, provided at a second end of the second clamping arm, protruding towards the first clamping arm and forming a second pressing surface, with the second pressing surface and the first pressing surface set oppositely, and when the first clamping arm rotates to close with the second clamping arm, the first pressing surface and the second pressing surface press tightly;
• wherein the extension length of the first pivot portion of the first clamping arm is substantially equal to the protruding length of the first pressing surface from the first clamping arm;
• the extension length of the first pivot portion of the second clamping arm is substantially equal to the protruding length of the second pressing surface from the second clamping arm;
• to make the first pressing surface and second pressing surface receive even force when pressed.
