Push-pull pliers with hammers
View Patent ↗A push-pull pliers with hammers utilizing the mechanism of conventional vise-grip locking pliers comprises a fixed jaw with threaded hole and hammer head and a slidable hammer assembly attached to either side of the body of the fixed jaw. Gripping a workpiece, such as a cotter pin, a nail, a tube, etc., the slidable hammer assembly can be used to push the workpiece into its base or to pull the workpiece out of its base. The slidable hammer assembly is detachable from the body of the present invention.
1. A push-pull pliers with hammers having a fixed handle and a movable handle linked together by a spring and a toggling linkage mechanism comprising:
a movable jaw;
a fixed jaw with a rectangular hammer head having five hammering surfaces, one on a top surface and one on each remaining four sides;
a threaded hole formed in a body of said fixed jaw;
a straight rod having a distal end having a first metal stop attached thereto and a proximal end that is threaded;
a second metal stop threadedly engages said proximal end of said straight rod; and
a hand-grip cylindrical hammer having flanges at each end slidable on said straight rod between said first metal stop and said second metal stop.
2. The push-pull pliers with hammers according to claim 1 , wherein said threaded hole is located as close to said fixed handle as possible.
3. The push-pull pliers with hammers according to claim 1 , wherein said straight rod threadedly engages said threaded hole of said fixed jaw.
4. The push-pull pliers with hammers according to claim 1 , wherein said body of said fixed jaw comprises two flat surfaces, a front flat surface and a rear flat surface.
5. The push-pull pliers with hammers according to claim 4 , wherein an axis of said straight rod is perpendicular to either said flat surfaces of said body of said fixed jaw.
6. The push-pull pliers with hammers according to claim 1 , wherein said first metal stop, when hit by said hand-grip cylindrical hammer, serves as means to apply pulling force to a workpiece clamped by said push-pull pliers; and said second metal stop, when hit by said hand-grip cylindrical hammer, serves as means to apply pushing force to said workpiece clamped by said push-pull pliers.
