Abstract

A cutting head for a hydraulic power tool includes a first jaw that includes a first ear configured with a slot for receiving a corresponding ear. The second jaw includes a second ear with a third ear bore that aligns in between a first ear bore and to a second ear bore of the first ear when the second ear is coupled in the slot of the first ear. The cutting head further includes a spring-biased flange coupled to a blade mounted to the first jaw and a retained coupled at a fixed position to a blade mounted to the second jaw. The retainer is configured to receive the flange during a cutting action such that the flange prevents the blades from shifting out of alignment during the cutting action.

First claim

I claim:

1. A cutting head for a hydraulic power tool, the cutting head comprising:
a first jaw having a first blade;
a second jaw having a second blade;
a flange, configured as a separate component, directly coupled to and extending from the first blade; and
a retainer configured as a separate component from the second blade and from the first and second jaws, and removably coupled to the second blade first blade during a cutting action and receive the flange before and during the cutting action to resist movement of the first jaw or the second jaw out of alignment during the cutting action,
the flange extending through the retainer during the cutting action so that the flange travels in one side of the inner groove and exits at another side of the inner groove.

2. The cutting head of claim 1 , wherein the inner groove receives the first blade.

3. The cutting head of claim 1 , wherein the flange is pivotably coupled to the first blade.

4. The cutting head of claim 1 , wherein the flange includes a detent plunger to engage a hole of the first blade.

5. The cutting head of claim 1 , wherein the retainer includes a first leg that overlaps with a first lateral side of the second blade and a second leg that overlaps with a second lateral side of the second blade, and
wherein the first lateral side is opposite the second lateral side.

6. The cutting head of claim 1 , wherein the retainer is fixed relative to the second blade.

7. The cutting head of claim 1 , wherein the second blade is fixed within the inner groove of the retainer, and the inner groove receives the first blade during the cutting action.

8. The cutting head of claim 1 , further comprising:
a hollow pin defining an axis,
wherein the first jaw and the second jaw rotate about the axis.

9. The cutting head of claim 1 , wherein the retainer is mounted to a top portion of the second blade.

10. The cutting head of claim 1 , wherein the flange is moveable between an extended position and an open position, and
wherein in the extended position, the flange extends into the retainer during a cutting action and in the open position, the flange does not extend into the retainer.

11. The cutting head of claim 1 , wherein the first blade is secured to the first jaw with a first pair of blade mount screws and the second blade is secured to the second jaw with a second pair of blade mount screws.
