ABSTRACT:
A crimping tool includes an elongated first handle member, a pair of head plates pivoted to the front portion of the first handle member, and an elongated second handle member having a front portion pivoted on the head plates to allow movement of its rear portion away from and towards the rear portion of the first handle member. The second handle member has a curved toothed section formed on its front portion. A pawl member is resiliently mounted between the head plates and engages with the curved toothed section of the second handle member when the second handle member moves toward the first handle member. A first stripping plate is fixed on the middle of the first handle member and has one side formed with a plurality of first stripping grooves. The first handle member further has a rectangular opening adjacent to the first stripping plate and a plurality of second stripping grooves formed in the rectangular opening and aligned with the first stripping grooves. A second stripping plate is pivoted to both the first and second handle members and has one end with third stripping grooves that matches the stripping grooves of the first stripping plate. An extension spring has one end connected to the second stripping plate and another end connected to the first handle member.
