ABSTRACT:
The knot tyer in accordance with the present invention includes, a hollow, elongated body member with a coil expansion spring mounted tubular piston therein and a release thereon. The hollow, elongated body member has a tubular piston slidably mounted and constrained within a cylindrical, hollow bore therethrough. The tubular piston has a first shoulder, a second shoulder, and a groove extending around the diameter of the tubular piston. The cylindrical, hollow bore in the rear end of the hollow, elongated body member accommodates in free longitudinally sliding manner a first shoulder on the tubular piston as well as a coil expansion spring encircling the tubular piston. The cylindrical, hollow bore in the front end of the hollow, elongated body member accommodates in free longitudinally sliding manner a second shoulder and a groove on the tubular piston. The release is pivotally attached to the hollow, elongated body member by a pin, which pin allows the release to pivot on the external longitudinal axis of the hollow, elongated body member. The tubular piston has a grooved and notched front end. The front end of the tubular piston is grooved so as to be open on the top and hollow internally. The front end of the tubular piston has a diagonal notch in the shape of a jaw cut therethrough.
