The knob 201f drives the first bidirectional threaded rod 201e to rotate, thereby driving the first slider 201c to move, so as to drive the clamping plates 201d to clamp and fix both ends of the wire and cable. After that, close the door and turn on the low-temperature box body 102 to lower the temperature inside the low-temperature box body 102. Finally, the staff rotates the runner 202g to drive the rotating rod 202e to rotate, thereby driving the worm 202f to rotate, and then driving the worm gear 202d to rotate. When the worm gear 202d rotates, it drives the second bidirectional threaded rod 202c to rotate, thereby driving the second slider 202a to move, and then driving the fixed rod 202b to move. In this way, the wire and cable are stretched by driving the movable column 201a to move. During the stretching process, the staff can directly observe the data displayed on the display screen 203b.
