Abstract

An example shearing head includes a first member and a second member being rotatable about a pin. The first member has a shearing surface forming a substantially right angle with a first lateral surface of the first member. The second member has a shearing surface forming a substantially right angle with a second lateral surface of the second member. The second member includes a first distal surface and a second distal surface forming a substantially right angle. The first distal surface and the second distal surface are substantially perpendicular to the second lateral surface. The second member includes a third lateral surface opposing the second lateral surface and a retainer is attached to the second member. A first surface of the retainer contacts the first distal surface, a second surface of the retainer contacts the second distal surface, and the third lateral surface contacts a third surface of the retainer.

Dependent claims

A shearing head comprising:

a first jaw rotatable about a pivot axis and including a first shearing member, the first shearing member having a first shearing surface and a first lateral surface, the first shearing surface forming a right angle with the first lateral surface;
a second jaw rotatable about the pivot axis and including a second shearing member, the second shearing member having a second lateral surface, a second shearing surface, a first distal surface, and a second distal surface, the second distal surface facing the first shearing surface, and the second shearing surface forming a right angle with the second lateral surface;
and
a blade retainer attached to the second jaw, the blade retainer in contact with the first distal surface, the second distal surface, and an outer lateral surface of the second jaw, the blade retainer resisting movement of the first jaw that is transverse to a shearing plane during a cutting action and the blade retainer distributing an impact force applied to the blade retainer to the first distal surface and the second distal surface of the second jaw so that the impact force is compressively absorbed by the first distal surface and the second distal surface of the second jaw.
