Claim:
A spacer jig using as a tool for replacing a spacer damper on overhead power lines, the spacer jig comprising; a frame having a polygonal shape of two flat panels in parallel with a clearance for mounting a set of fixtures arranged even intervals in radial direction between the two flat panels ( 30 ), a set of said fixtures consisting of stationary hexahedron nuts ( 40 ) and rotational hexahedron nuts ( 50 ) mounted between the two flat panels ( 30 ), wherein said rotational hexahedron nut ( 50 ) has integrally formed disk-shaped hinges ( 51 ) protruded on front and rear surfaces to mate with circular hinge holes formed on the frame, so that said rotational hexahedron nut ( 50 ) can be rotated within a limited angle with respect to an axis of the disk-shaped hinges ( 51 ), a set of clamp shafts ( 20 ) forming long cylindrical-shape with threaded end portion for inserting into the fixtures, a cable gripping unit consisting of a clamp ( 10 ), lid ( 12 ), snapping latch ( 13 ) and locking detent ( 14 ) for opening and closing the lid ( 12 ), and a clamp mounting unit ( 25 ) for rotationally mounting the cable gripping unit on top of the clamp shafts ( 20 ), wherein said clamp mounting unit ( 25 ) is consisted of a circumferential groove ( 24 ) integrally formed at top end of the clamp shafts ( 20 ), a retainer ( 26 ) formed a semi-circular cutout at its center and divided to two pieces for laterally engaging to the groove ( 24 ), a mounting plate ( 27 ) having four bolt holes at each corner, and four fasteners for securing and fixing said retainers ( 26 ) and mounting plate ( 27 ) together to the bottom of the clamp ( 10 ).
