    摘要： A hand operated crimping tool comprising a crimping head 10 and a pair of operating handles 12 for actuating said crimping head. At least one of said handles includes a force sensing arrangement including detent mechanism for maintaining handle portions 80, 88 in an unloaded position until a predetermined crimping force is applied by the crimping head whereupon the detent mechanism releases to allow slight, relative pivotal motion between the handle portions. The detent arrangement includes a tapered extension post 90 defining a recess 100 and a grip 80 pivotally connected to the post. The grip slidably mounts a spring biased slider 98 which defines a recess, confrontingly aligned with the recess in the tapered post when the grip and extension are in an unloaded position. A detent ball 94 is captured between the confronting recesses. The force exerted by the slider on the detent ball resists pivotal movement between the grip and the extension. When the crimping force applied by the crimping head exceeds a predetermined level, the detent ball disengages the slider and allows the grip to pivot slightly with respect to the extension thus providing a tactile and audible indication to the operator that a predetermined crimping force has been reached.
