Cable tie tensioning and cut-off tool

摘要

A hand held tool for the tensioning and severing of cable ties, including reciprocating means for tensioning the cable tie tail, locking means to prevent further tensioning upon the attainment of a preselected tension level in the tie tail, and severing means to sever the tie tail from the cable tie head.

主权项

1. A tool for tensioning and severing an elongate cable tie, said tie having a tie head portion and tie tail portion, the tool including:
a pistol-shaped housing including a handle portion and a barrel portion; an elongate trigger extending downwardly from the barrel portion, forwardly of the handle portion and displaceable toward and away from the handle portion; a tensioning mechanism in the barrel portion operable to engage a tie and apply tension to the tie in response to movement of the trigger toward the handle portion; a locking mechanism in the barrel portion operable to stop application of tension to the tie when tension applied by the tensioning mechanism reaches a predetermined tie tension; a cutoff mechanism in the barrel portion operable to cut off the tie when the locking mechanism stops tie tensioning; a tension-lock-cut linkage wherein said tension-lock-cut linkage includes a pawl link mounted for horizontal, linear reciprocal movement relative to the housing, the pawl link further including a forward end having a pivotally attached tie gripping pawl; and wherein said tension-lock-cut linkage is coupled to a tension adjustment system.
