Abstract:
1. A crimping tool for crimping a coaxial cable with a cable-end connector, comprising: a tool body comprising a receiving chamber defined therein, two pivot holes aligned at two opposite lateral sides thereof near one end of said receiving chamber and a positioning block disposed in an opposite end of said receiving chamber; a lever comprising a front connection portion, a rear operating portion backwardly extended from a rear end of said front connection portion, and a first pivot located on a front end of said front connection portion remote from said rear operating portion and pivotally connected between the two pivot holes of said tool body; and a linking mechanism axially slidably coupled to said tool body inside said receiving chamber and movable by said lever, said linking mechanism comprising a link having one end thereof pivotally connected to said front connection portion of said lever, a locating block located on an opposite end of said link and a working device connected to said locating block, said working device comprising a shank, a connection member axially extended from one end of said shank and fastened to said locating block, a rod-shaped working head located on an opposite end of said shank remote from said connection member for inserting into a collar of the cable-end connector, said working head being longer than said collar and having a rear surface continuously bent from a rear side of an outer surface of the working head to said shank, a sliding socket axially slidably coupled to said shank and adapted for capping onto said working head, said sliding socket having a sleeve that presses around the outer surface of said working head, a sleeve portion bent inwards from a rear side of said sleeve and extending on the rear surface of said working head to said shank, said sleeve portion including a rear wall surface perpendicular to the surface of said shank, a front edge of said sleeve converging forwards to form an annular guiding bevel in order to facilitate pressing and guiding said collar of the cable-end connector, and a spring member mounted around said shank and stopped between a front surface of said locating block and the rear wall surface of said sliding socket to force said sliding socket onto said working head; wherein: when the inner diameter of said collar is larger than the outer diameter of said sliding socket, said working head of said working device and said sliding socket are mounted into said collar simultaneously; when the inner diameter of said collar is smaller than the outer diameter of said sliding socket but greater than the outer diameter of said working head, said collar pushes against said sliding socket to compress said spring member, and said working head is inserted into said collar.
