The invention is related to a crimping tool. The crimping tool includes a connection rod having one end pivotally connected to the first handle and the other end of the connection rod pivotally connected to a crimp section. A first screw rod is disposed at the second handle of the crimping tool. The first screw rod drives the connector which leads the first handle to displace. The movement of the first handle leads a connection rod to displace. As a result, the position of a crimp section on the first handle can be adjusted.
