A segment screw dissembling device is provided to dissemble a segment screw without damage or of a screw assembly because first and second clamps are separated from each other by a cylinder. A segment screw dissembling device comprises a base frame(10), first and second clamps(20,30) which hold both ends of a segment screw, a cylinder(40) which approaches of separates the first and second clamps, and a cylinder driving unit which moves a cylinder shaft(41) of the cylinder. The cylinder is anchored to the first clamp. The cylinder shaft passes through the first and second clamps. The end of the cylinder shaft is anchored in the second clamp. The first and second clamp are distanced from each other in the tension of the cylinder shaft. The cylinder driving unit comprises a first unit(51) which separates the interconnected segment screw primarily, and a second unit(52) which separates the separated segment screw in relation to the screw shaft secondarily. |
