Embodiment Construction
[0039] In the figure, a support 4 is set on the support base 7, a crossbeam 1 is arranged at the upper end of the support 4, an upper chuck 2 and a force-sensitive sensor 3 are arranged in the middle of the crossbeam 1, and one end of the metal wire 12 is connected with the upper chuck 2 and the force-sensitive sensor 3. One end links to each other with the lower clamp 13, and the lower clamp 13 is fixed with a metal frame 14, and an iron block 15 is fixed inside the metal frame 14, and an electromagnet device 16 is arranged below the metal frame 14. The force-sensitive sensor 3 is connected with the force-sensitive sensor measurement controller 8 through an interface, and the force-sensitive sensor 3 is used to measure the tensile force of the metal wire 12 , and can be displayed through the force-sensitive sensor measurement display screen 9 . The electromagnet device 16 is used to apply a pulling force to the metal wire 12 by acting on the iron block 15 through magnetic forc...
