Manual bundling tool
First Claim
1. A manual binding tool, comprising:
- a tightening mechanism configured to pull a tie portion of a binding tie through a head portion of the manual binding tool;
a cutting mechanism configured to cut the tie portion in a place in a vicinity of the head portion;
a first lever and second lever that are pivotally coupled to each other;
a tightening linkage mechanism linking the first lever and the second lever with the tightening mechanism in a first state where the tie portion is pulled through the head portion of the manual binding tool as the first and second levers move from a first position to a second position intermediate the first position and a third position;
a cutting linkage mechanism linking the first lever and the second lever with the cutting mechanism in a second state where the tie portion is cut as the first and second levers move from the second position to the third position; and
a switching mechanism configured to cause the tightening linkage mechanism to establish linkage of the first and second levers with the tightening mechanism in the first state by engagement of a support roller in a tip end recess of a tension arm connected to a triangular link engaging the tightening linkage mechanism when a pulling force applied to the tie portion by the tightening mechanism is less than a threshold value, thereby disabling operation of the cutting linkage mechanism in the first state, said switching mechanism being further configured to cause the cutting linkage mechanism to establish linkage of the first and second levers with the cutting linkage mechanism in the second state by disengagement of the support roller from the tip end recess of the tension arm connected to the triangular link now engaging the cutting linkage mechanism when the pulling force exceeds the threshold value, thereby disabling operation of the tightening linkage mechanism in the second state.

Abstract
A manual binding tool in which, without transferring the fingers, tightening and cutting can be performed simply by gripping a pair of levers. The manual binding tool includes a tightening mechanism that pulls a projection tie portion that is passed through a head portion, a cutting mechanism that cuts the projection tie portion in the vicinity of the head portion, first and second levers, a tightening linkage mechanism that links the levers with the tightening mechanism in a state where the projection tie portion is pulled by gripping of the levers in a range within a predetermined angle, and a cutting linkage mechanism that links the levers with the cutting mechanism in a state where the projection tie portion is cut by gripping the levers beyond the predetermined angle. A switching mechanism alternatively allows one of the tightening or cutting linkage mechanism to operate based upon tightening force.
