ABSTRACT:
A tool for extending and thereby restoring the compression of a fuse block spring (46). The tool comprises a rod (10) fixedly mounted at one end to extend from an end of one arm (14) of a pistol grip and at the other end is slotted to admit the spring tang as the rod (10) is inserted within the spring coils. When the rod (10) is stopped, either by a portion (48) of the spring or the fuse socket base, a finger (32) at the end of a sleeve assembly (18, 29) slidably fitted over the rod (10) is rotated to capture an initial coil of the spring. The sleeve assembly (18, 29) at its other end is pivotally connected to an end of a second arm (22) of the pistol grip, which second arm (22) is also pivotally connected to the first arm (14). The second arm (22) is closable on the first arm (14) to retract the sleeve assembly (18, 29) along the rod ( 10) to extend the spring (46) to the required length.
