The utility model relates to an insulated wire ligature pincers, its characteristics are: it is including keeping silent surely, moving and keep silent, surely, it is curved body to keep silent and move to keep silent, keeps silent surely and arranges the top of fixed pincers handle in and link firmly, and it keeps silent to move arranges the top of rotor arm in and link firmly, moves and keeps silent with to keep silent concave the 5th pin joint relative, the rotor arm surely articulated with the first pin joint of fixed pincers handle, and the 6th pin joint of rotor arm is articulated with the third pin joint that removes the pincers handle, the one end of connecting rod with remove that the pincers handle is articulated, the other end articulates with fixed pincers handle. During the use, ligature is later done to the insulated wire by the elder generation, then makes removal pincers handle wind fixed pincers handle rotate clockwise, and the drive rotor arm is around fixing pincers handle anticlockwise rotation to open and keep silent, will open ligature department later of arranging the insulated wire in of keeping silent, again the antiport remove the pincers handle around fixed pincers handle anticlockwise rotation, drive the rotor arm around fixed pincers handle rotate clockwise, the closure of keeping silent is pressed from both sides ligature department later of insulated wire tightly.
