[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model drives the threaded rod to rotate by rotating the rotating rod clockwise, and the rotating rod drives the threaded rod to rotate. The rotation of the threaded rod will lengthen the length of the threaded rod located inside the U-shaped frame, thereby pushing the fixing ring to move downward. After the fixing ring contacts the titanium material, the rotating rod continues to rotate, and the fixing ring drives the titanium material to move downward. The titanium material drives the placement ring to move downward. When the placement ring moves downward, it drives the first slider to move downward along the first slide rod. At the same time, the first slider compresses the spring, so that the spring has a certain elasticity. When the titanium material is stretched, the diameter of the titanium material will become smaller. At this time, the spring will push the first slider to rise, and the first slider drives the placement ring to rise, so that the titanium material continues to be fixed between the fixing ring and the placement ring to prevent the titanium material from falling off. The utility model drives the bidirectional threaded rod to rotate by the counterclockwise servo motor. Because the threads at both ends of the bidirectional threaded rod are opposite, the rotation of the bidirectional threaded rod will cause the two second sliders to move along the second slide rod in the direction away from each other, thereby stretching the titanium material. The rangefinder on the second slider can measure the distance between the two second sliders before and after stretching and feed it back to the display screen, thereby facilitating the calculation of the stretching amount.
