Abstract
Pruning shears include a cutting head with a spring-biased blade; a driving line connected at a first end to the blade; an elongated body; a handle; and a frusto-conical shaped wheel connected rotatably to the handle. The diameter of the wheel at a first end being smaller than the diameter at a second end. The line is wound into a spiral groove around the wheel at the first end; a second end of the line is attached to a second end of the elongated body; and the line wound around the wheel moves toward the second end of the wheel when unwinding a part of the line from around the wheel and winding another part of the line around the wheel for decreasing the distance between the first and second ends of the line, resulting in movement of the blade in relation to the jaw, when the handle is moved.
