Abstract:
1. A cable tie tool comprising: a tool handle having a barrel structure; a tool head supported within said barrel structure, the tool head having a forward end to which may be secured a cable tie for tensioning thereof; an elongate lever supported within said tool handle by a pivotal connection thereto, said lever having near and distant positions thereon which have corresponding longitudinal reduced and increased separations from said pivotal connection, said lever being coupled to said tool head and pivotal between neutral and tensioned positions such that, when a cable tie is secured to said tool head, pivoting said lever from said neutral to tensioned positions causes said lever to apply a force to said tool head to increase the tension in the cable tie in proportion to the force applied to said tool head by said lever; a variable trigger linkage supported within said tool handle by a connection thereto, said trigger linkage being coupled to said lever and movable between open and closed positions such that moving said trigger linkage from said open to closed positions causes said lever to pivot from said neutral to tensioned positions, said trigger linkage engaging said lever alternatively at said near or distant positions to provide said coupling to said lever such that, when a uniform force is applied to said trigger linkage for movement thereof from said open to closed positions, said engagement at said distant position results in said force applied to said tool head by said lever being greater than said force applied to said tool head by said lever which results from said engagement at said near position.
